How many years does a on-grid setup like yours, with similar capacity, take to pay off in electricity savings? And how much does it cost? Thank you, love this style of informative videos.
I think you should also talk about how load calculations need to be done roughly and how battery capacity needs to be chosen for ex: 100ah vs 150 ah and how backup time will be affected and such. This will ensure viewers are well educated and can make proper judgment on which inverter and battery to buy depending on their load needs.
1kw generates 4units per day and 5kw approx 20 units per day/year average. Coming to the battery how many wh needs for your home(power cut hrs and what load needs that time ex.75w fan*4=300w and uses 4hrs = 1200wh (1.2kwh or 1.2 units) so u need a battery including depth of discharge and autonomy all loses 1200wh*3.676/24(two batteries & also depend on inverter sizes) = 183.8ah ~180ah or 200ah

4:34 Dear Ranjit, why did you go with lead acid batteries? Their efficiency is only 50 percent and they emit H2 which is highly flammable specially in enclosed areas like your cabinet. These are only recommended for tight budget projects. A good LFP battery can easily serve for 20 years in stationary storage. Or maybe you've planned to switch to Lithium when these stop working?
Hi Ranjit, My question is that in an on-grid system, if in an area there are frequent power cuts then the system won't send electricity back to grid. Is there option of a hybrid sysytem which is on-grid (for net metering benefits) and also saves the power in the batteries when there are power cuts? Thankyou.
Yes, instead of adding more panels and a Offgrid inverter, he could have changed the Inverter to Hybrid and added LFP batteries to it. When the Grid goes down, those panels will still charge the batteries and power the house/office.
Just the video I wanted, I have some questions can you please explain in your next video: 1. What is the cost like (Approximate just to get an idea) 2. How long the battery last. 3.

I have a few questions to ask you 1. Your opinion on hybrid systems 2. Brands to go for 3. Did you apply for a subsidy and how was your experience on that
Didn't opt for Hybrid coz our Society does not allow that, it has to be a strict on-grid with max capacity of 5Kva they have too many restrictions in our Society, also as it's a Pvt Gated Society we don't have any subsidy but if you have a Govt meter then you can opt for Subsidy and that differs from state to state.
For Pvt Big gated Society their is only 1 central Govt meter all individual meters are by the society and are net-metered and very high tech meters so they do track the extra electricty that we export (in-fact we have an app on our phone from that we can see the exported units in real time, so daily we get an idea how much power we consumed from the grid and how much was exported) so we do get the metering benefits but we can't avail any subsidy as our meter per house is a pvt meter. Large Gated Society have very different rules, also the electricity rate is also decided by our Society and not the Govt. The society indirectly pays the govt a fixed rate for elecricity.
@@almondnineFor off-grid system if you own the roof, no one can stop you as you are not exporting any electricity back to the grid or the society, it's a completely isolated system with different wiring, it's just like you are installing an inverter in your house they can't stop that, it's just that you are powering that inverter from Solar power. But yeah if it's an on-grid system you have to follow the limits as you are exporting back power to the society and the grid.

This is the exact video you need to know about solar installation. You will get the checklist here and according to your condition just tick the boxes and buy accordingly.
Thank you. Very informative for me as I am planning to get it installed for my home. Few questions: 1. How to decide what capacity to go for? E.g 5kw vs 3kw, etc. 2. Any suggestions on which vendors are reliable (e.g in Bangalore)? 3. A rough estimate on pricing would also be good (to make sure my vendor isn't cheating me) 4. My society has DG. Any possibility of making it work with on-grid solar system (to cover power cuts during night time?). My vendor says it's not possible.
From what I have seen, the on grid system stops working if the grid doesn't have power.. This is a safety feature for personnel working on power lines. The electricity board starts adding new maintenance charges that actually eat up into your savings..don't expect anything great from the net metering if it becomes negative also
Kindly make a comparison of the energy production in peak summar and winter. To recover the cost what is the approx duration it needs to run, as MKHBD did in his video. Obviously the total cost and availability of the same in tier 2 cities.
Hi sir, regarding on-grid system do discuss the amount difference in electricity bills pre and post installing the solar power system. Also there are many brands and firms doing this installation process, which ones to prefer and which to avoid.
2:50 All Passively cooled ongrid inverters must have at least 30cm clearance on the top and 30cm clearance sideways, 50cm clearance below the inverter and 50cm on the front. (Please check the user manual) Since the Growatt inverter you are using only has heat sinks (no fans), therefore it require good ventilation. Otherwise inverter will start derating (especially in summers) and and it’s components will be damaged. And sometimes whole unit may catch fire 🔥. There are several videos on RUclips too Must follow standard installation procedure of inverter otherwise it will overheat and 💥 POSSIBLE FIRE HAZARD
Hi Ranjit Sir, i waited so long for this informative video. But would love to know the services and vendors you opted for each and every component so that we can compare it with the ones available in our area.
Please do also make a video on the companies which can be considered or relied for Solar Power Systems as we in India now have hundreds of companies offering various products in this category. Also make a video on the complete process one has to go through if they plan to install a solar rooftop plant in their house.
halfcut bifacial Monoperc panel cost 27 per Watt ,Battery 150Ah - 12500, Luminous Hybrid TX 5 KVA MPPT inverter with net metering facility - 60,000 net meter cost - 12000
Great video. Just 1 confusion with the specifics. PWM is actually a method to generate AC from DC by control of switches (Mosfet ot Thyristor) whereas MPPT is an algorithm to extract max power from the system in given conditions. Even those solar inverters that operate with MPPT could have PWM as control method for generating AC from DC.
Thank you for the useful information. Please share details of on-grid vendors in the next video. I tried contacting tata solar through their online forms, but not a single customer rep has called. None of the entries on Google maps seem to have decent reviews. If there are some online resources listing solar vendors, please share them as well. The only one I've found and shortlisted till now is loom solar. Looking forward to your next video to get some inputs on the brand and vendor.
Hello Ranjit bhaiya, was waiting from long time for you to give this informative video. Could you please point out the cost, company or service provider of each component and what is its role. Also it would be really helpful for the viewers if a separate video comes from you about how to maintain the longevity of the solar systems. Thanks !!!
Very much informative. Next week i will go for 3Kwatt ongrid system. My vendor said that he will provide Adani panels. What is your opinion about the panels? What maintenence required for panels, afraid that panels will be placed on slanted roof top at a height about 60 foot,. not easily acessible. Your guidance is the most welcome.
1) Why you're not using bifacial solar panel. 2) What if, if we use battery with on grid solar panel for backup. 3) Is there any limit for using on grid system or we can use as many as we want? 4) Tell about lithium-ion battery is it worth it or not? 5) Right now which type of solar panel technology is most efficient & which company have it? 6) Upcoming superior technology in India. 7) Tools for cleaning solar panel & how to clean them? 8) Do's & don't while cleaning? 9) How to get most output? 10) Most important things to know while installing solar panel like stands, wire etc.
halfcut bifacial Monoperc panel cost 27 per Watt ,Battery 150Ah - 12500, Luminous Hybrid TX 5 KVA MPPT inverter with net metering facility - 60,000 net meter cost - 12000
1) Why you're not using bifacial solar panel. costlier and not worth extra price for 5-10% more generation 2) What if, if we use battery with on grid solar panel for backup. You can use normal inverter battery but that won't be charged by solar actually, you'll be using grid power to charge it and on grid does not produce energy during power cut 3) Is there any limit for using on grid system or we can use as many as we want? The maximum solar you can install is same as your meter load. Residential meters are capped at 20kW load so max you can install is 20kW. In most cases, you won't have a big enough roof on residential property to have 20kW solar but thats what the rule says. 4) Tell about lithium-ion battery is it worth it or not? Only if you live in rural area with more power cut hour than power available hours 5) Right now which type of solar panel technology is most efficient & which company have it? mono perc best
1. I live in a small town in Bihar where power cuts are frequent. We do not get continuous power supply during the day time and on an average, we get 16 hours of power supply out of 24 hours in a day. Considering this, should I go for on on grid/off grid or hybrid? 2. If someone buys an on grid, will the power from grid auto connect whenever the sun sets or on cloudy days? 3. If the average power consumption in my house per day is 500 watts, what should I opt for (on/off grid or hybrid)?
Hi Ranjeet, I also installed and activated an on-grid solar system of 3.2 Kw capacity in Bengaluru in Feb this year, I got the MPPT inverter of 4Kw from the EPC company. They actually tried to push the Enphase microinverters to me, but it didn't fit my budget and also the efficiency gain of those didn't feel like good investment. They have been working above my expectations or calculations and I installed it without subsidy because if you buy with subsidy the rate the DISCOM pays you for exported units goes down, in the long run I would make better returns by not opting for the subsidy. Plus I can avoid chasing the EPC/government to get the subsidy if it doesn't happens to come in time. I just have three questions, how often do to clean it and how, do you have any tools or Excel sheets as to see what returns It's generating, if you took an AMC from the EPC vendor, what's the charges?
Good to hear your plant is working great. I haven't taken any AMC, I was not Cleaning the planels eaier as every 10 odd days we were having rains, but now we are having a dry spell, so good idea to clean every 3 odd weeks. I noticed a improvement of about 4-5% after the panels are cleaned. I have ordered a new Cleaning brush that has water outlets, will get it delivered next week so that should make the Cleaning job a lot easier. But if you don't clean them often it's okay, as in our old setup we didn't clean for 6 months just noticed a drop of 7-8% generation.
Can you please provide the contact of the vendor? I assumed one has to chase govt for on grid solar system even when opted without subsidy.....also what rates are they paying for exported units?
We have 2kva hybrid system, which has 4 batteries and also is grid tied. You should have gotten a hybrid inverter for the offgrid one. Meanwhile we also installed 3kw ongrid
1. What was the total cost of both On-grid and Off-Grid systems for 5KW? 2. What additional costs do you have to incur regarding net meter and government formalities? 3. What are the Precautions and Safety measures needed for On-Grid system?
Hi.. if some one interested for solar simply go for ongrid-hybrid. No need of two. Ongrid-hybrid comes with batteries and even during power u can generate and utilise in your home
Thank you very much for this informative video. Can I install solar panels at little height on the roof, ie by using taller beams of galvanized steel, so that I can use the space under it as a shed or storage?
For on-grid the return on investment would be anywhere from 4.5 - 6 years, based on the type of panels used and subsidy available or not. For off-grid setup it would be 9 odd years and does not make that much sense as replacement of batt cost would be there.
About 7000 units per year generation on average. If all the units are used by you, you can recover total plant cost in 5 yrs. Panel warranty is 25 yrs and many inverters come with 10 yr warranty
Different states have different buy back policy for power. Visit your state discom policy for more clarity. But if you size plant correctly for your home needs, ROI will be faster. Basically you need to pull last 12 month bills and sum total units and divide by 12 If that value is 400, you need 4kw. If it's 500, you need 5kw and so on
I have a few questions 1. How is Tata Power equipment and service wise ? 2. Can you short list a few good vendors in part 2 ? 3. What is the make of your current panels and how good is Waaree ? Thank you for this and upcoming videos in this series !
Hi Ranjit, Your video is really interactive and informational. Well I am working on solar panel installation project that take cares of end to end process including site survey to installation of solar panel. Could you pls let me know, what are the thing we check and equipment's are needed while we are on site survey for installing solar panels Specially while site survey.
What is your opinion on using Lithium iron phosphate batteries...vs lead acid that needs top up of acid and less Max power draw? Also lithium has longer life.. Cost is more..so is it worth it? Looking forward to part 2... And part 3.. about maintenance
halfcut bifacial Monoperc panel cost 27 per Watt ,Battery 150Ah - 12500, Luminous Hybrid TX 5 KVA MPPT inverter with net metering facility - 60,000 net meter cost - 12000
simple formula for selecting a solar system type(varies case by case): 1) If you are facing extreme power cuts go for offgrid system. 2) If you are facing less frequent power cuts go for a hybrid system. 3) If you have little to no power cuts go for ongrid system. Also if you have a higher budget go for Lithium ION battery packs for hybrid or offgrid system. They usually come with a 10 year warranty and 25 year life span.
My last question, if I wish to go with storage/battery, as per the average consumption (500 watts) per day, how many volts or KV I need to consider for an inverter and how much power for a battery (AH)?
Please suggest some good brands and do we need to change the wiring system of the entire house?can you also give an approximate idea about the area required for say 1KW of solar panels?
Please list out each cost in money terms also either your cost or general market cost or both to just get rough idea of cheap expensive on a personal level
Please also talk about number of strings you have installed how the hybrid system works and why is your panels.mounted so steep im from chennai the angle is just 11 or 12 here your panels seems to be installed at around 25 to 30 degrees wont it impact production?
Hi Ranjeet, How much is load efficiency in the winter season and Summer during the night time. What is the storage capacity of the Inverter installed? Thanks
If it's a new construction, can we plan a South facing sloped roof for panels or is it necessary they have their own separate steel skeleton supporting them ?
Hey ranjit! What about hybrid ones? My ques is the excess energy generated should go to the grid which is on grid but at the same time can we save those energy in batteries before it goes to the grid(so that we can use it when the power is cut) 1.panel to our use + charge batteries first And then 2.can it go the grids? Is this possible?? Pls answer ranjit!!!
Hey I have already an inverter with battery installed in my house for power backup . Now if i want to install solar system..should it be ongrid or offgrid? What is the difference in price in ongrid and off-grid system? What are the advantages and disadvantages of both the system when compared side by side.?
Ranjit sir, what's the total set up cost of ur ongrid solar panel also can u tell about the difference in the electricity bill after the installation of it and can we set up these kind of system in Delhi as it's a bit conjusted areas here in Delhi.
Can you please review wzatco Yuva plus projector its a budget projector i need to know your experienced knowledge about this projector please review it will be helpful to me and many others as well. Merry Christmas
Is the net-metering system only provided by private companies or can the government distributors provide them as well? Also, do we need to arrange for batteries to store the excess power generated by the on-grid system in case the net metering system is not yet installed?
Hello Ranjit Sir, first of all thankyou for making this series to educate your viewers. So my ques is, as you own a nexon ev, do you use your solar system to charge it up ? if you do then the power is taken from the on grid or the off grid system, i have heard ev charging takes up a lot of power, is a solar system capable of delivering that amount of power ? Thankyou
Meine apne shop pr 200w ka mono panel lagaya hai with exide 1100va solar inverter & 75ah lead acid solar battery without any controller. But isme toh 1 fan bhi nai chalta hai .

hi sir ,could you please make this type of edu videos on the different type of wifi networking systems like the one you recently bought tp link omada most people including me dont know about that kind of stuff please do make video on that topic.
Efficiency of solar system almost becomes half after some time. Is it true? If yes, then periodic cleaning will be helpful? And how to do the cleaning of the panels without any damage.
I think you can tabulate the solar panels types, their size, wattage and energy output. It would have been more easier to understand sir in my opinion.
Awesome man, I wish to get solar system installed at my house as well, unfortunately the requirements you mentioned doesn't get fulfilled. We have some shsdes from neighbours :(
It's my own independent house, with my own terrace so yeah they do allow but in our gated society we can put a max of 5Kva for On-grid system. If you are in a flat then they will generally not give permission as terrace is considered a common area in flats.
Nice Video Buddy one feedback, you spoke for like endless minutes, showing the setup without explaining what we need to understand from that setup. may be try explaining that is off grid and what is on grid first, Give some context about the panel because to me both panel looked the same.

This is the exact video you need to know about solar installation. You will get the checklist here and according to your condition just tick the boxes and buy accordingly.
Thank you. Very informative for me as I am planning to get it installed for my home. Few questions:
1. How to decide what capacity to go for? E.g 5kw vs 3kw, etc.
2. Any suggestions on which vendors are reliable (e.g in Bangalore)?
3. A rough estimate on pricing would also be good (to make sure my vendor isn't cheating me)
4. My society has DG. Any possibility of making it work with on-grid solar system (to cover power cuts during night time?). My vendor says it's not possible.
From what I have seen, the on grid system stops working if the grid doesn't have power.. This is a safety feature for personnel working on power lines.
The electricity board starts adding new maintenance charges that actually eat up into your savings..don't expect anything great from the net metering if it becomes negative also
Kindly make a comparison of the energy production in peak summar and winter. To recover the cost what is the approx duration it needs to run, as MKHBD did in his video. Obviously the total cost and availability of the same in tier 2 cities.
Hi sir, regarding on-grid system do discuss the amount difference in electricity bills pre and post installing the solar power system. Also there are many brands and firms doing this installation process, which ones to prefer and which to avoid.
2:50 All Passively cooled ongrid inverters must have at least 30cm clearance on the top and 30cm clearance sideways, 50cm clearance below the inverter and 50cm on the front. (Please check the user manual)
Since the Growatt inverter you are using only has heat sinks (no fans), therefore it require good ventilation.
Otherwise inverter will start derating (especially in summers) and and it’s components will be damaged. And sometimes whole unit may catch fire 🔥.
There are several videos on RUclips too
Must follow standard installation procedure of inverter otherwise it will overheat and 💥
POSSIBLE FIRE HAZARD
For now I would recommend you to keep the cupboard doors open 3:12
Hi Ranjit Sir, i waited so long for this informative video. But would love to know the services and vendors you opted for each and every component so that we can compare it with the ones available in our area.
Please do also make a video on the companies which can be considered or relied for Solar Power Systems as we in India now have hundreds of companies offering various products in this category. Also make a video on the complete process one has to go through if they plan to install a solar rooftop plant in their house.
1] Overall Cost for each variants
2] Installation process
3] Will they work in the rainy season??
halfcut bifacial Monoperc panel cost 27 per Watt ,Battery 150Ah - 12500, Luminous Hybrid TX 5 KVA MPPT inverter with net metering facility - 60,000 net meter cost - 12000
he is the og of tech review... Follwing him since 2014
Great video. Just 1 confusion with the specifics. PWM is actually a method to generate AC from DC by control of switches (Mosfet ot Thyristor) whereas MPPT is an algorithm to extract max power from the system in given conditions. Even those solar inverters that operate with MPPT could have PWM as control method for generating AC from DC.
Thank you for the useful information. Please share details of on-grid vendors in the next video. I tried contacting tata solar through their online forms, but not a single customer rep has called. None of the entries on Google maps seem to have decent reviews. If there are some online resources listing solar vendors, please share them as well. The only one I've found and shortlisted till now is loom solar. Looking forward to your next video to get some inputs on the brand and vendor.
Thanks for picking this topic. I heard about subsidies on the solar system. Please explain the same as well.
Hello Ranjit bhaiya, was waiting from long time for you to give this informative video. Could you please point out the cost, company or service provider of each component and what is its role. Also it would be really helpful for the viewers if a separate video comes from you about how to maintain the longevity of the solar systems. Thanks !!!
Very much informative. Next week i will go for 3Kwatt ongrid system. My vendor said that he will provide Adani panels. What is your opinion about the panels? What maintenence required for panels, afraid that panels will be placed on slanted roof top at a height about 60 foot,. not easily acessible. Your guidance is the most welcome.
1) Why you're not using bifacial solar panel.
2) What if, if we use battery with on grid solar panel for backup.
3) Is there any limit for using on grid system or we can use as many as we want?
4) Tell about lithium-ion battery is it worth it or not?
5) Right now which type of solar panel technology is most efficient & which company have it?
6) Upcoming superior technology in India.
7) Tools for cleaning solar panel & how to clean them?
8) Do's & don't while cleaning?
9) How to get most output?
10) Most important things to know while installing solar panel like stands, wire etc.
halfcut bifacial Monoperc panel cost 27 per Watt ,Battery 150Ah - 12500, Luminous Hybrid TX 5 KVA MPPT inverter with net metering facility - 60,000 net meter cost - 12000
1) Why you're not using bifacial solar panel.
costlier and not worth extra price for 5-10% more generation
2) What if, if we use battery with on grid solar panel for backup.
You can use normal inverter battery but that won't be charged by solar actually, you'll be using grid power to charge it and on grid does not produce energy during power cut
3) Is there any limit for using on grid system or we can use as many as we want?
The maximum solar you can install is same as your meter load. Residential meters are capped at 20kW load so max you can install is 20kW. In most cases, you won't have a big enough roof on residential property to have 20kW solar but thats what the rule says.
4) Tell about lithium-ion battery is it worth it or not?
Only if you live in rural area with more power cut hour than power available hours
5) Right now which type of solar panel technology is most efficient & which company have it?
mono perc best
1. I live in a small town in Bihar where power cuts are frequent. We do not get continuous power supply during the day time and on an average, we get 16 hours of power supply out of 24 hours in a day. Considering this, should I go for on on grid/off grid or hybrid?
2. If someone buys an on grid, will the power from grid auto connect whenever the sun sets or on cloudy days?
3. If the average power consumption in my house per day is 500 watts, what should I opt for (on/off grid or hybrid)?
Man i am watching him from so long, my 1st phone was moto G turbo 2016-17
Hi Ranjeet, I also installed and activated an on-grid solar system of 3.2 Kw capacity in Bengaluru in Feb this year, I got the MPPT inverter of 4Kw from the EPC company. They actually tried to push the Enphase microinverters to me, but it didn't fit my budget and also the efficiency gain of those didn't feel like good investment. They have been working above my expectations or calculations and I installed it without subsidy because if you buy with subsidy the rate the DISCOM pays you for exported units goes down, in the long run I would make better returns by not opting for the subsidy. Plus I can avoid chasing the EPC/government to get the subsidy if it doesn't happens to come in time.
I just have three questions, how often do to clean it and how, do you have any tools or Excel sheets as to see what returns It's generating, if you took an AMC from the EPC vendor, what's the charges?
Good to hear your plant is working great. I haven't taken any AMC, I was not Cleaning the planels eaier as every 10 odd days we were having rains, but now we are having a dry spell, so good idea to clean every 3 odd weeks. I noticed a improvement of about 4-5% after the panels are cleaned. I have ordered a new Cleaning brush that has water outlets, will get it delivered next week so that should make the Cleaning job a lot easier.
But if you don't clean them often it's okay, as in our old setup we didn't clean for 6 months just noticed a drop of 7-8% generation.
Can you please provide the contact of the vendor? I assumed one has to chase govt for on grid solar system even when opted without subsidy.....also what rates are they paying for exported units?
We have 2kva hybrid system, which has 4 batteries and also is grid tied. You should have gotten a hybrid inverter for the offgrid one. Meanwhile we also installed 3kw ongrid
1. What was the total cost of both On-grid and Off-Grid systems for 5KW? 2. What additional costs do you have to incur regarding net meter and government formalities? 3. What are the Precautions and Safety measures needed for On-Grid system?
I have a 5kw off grid system. Monoperc half cut panels and 4 lead acid batteries. My total cost was 4.85 lakh. I can comfortably run a 1.5 ton ac.
@@tinatuna7620which vendor have you opted for solar system installation?
Ranjit, what made you choose Luminous inverter for off grid system?
I would like to know if you spotted some good things about it.
Hi.. if some one interested for solar simply go for ongrid-hybrid. No need of two. Ongrid-hybrid comes with batteries and even during power u can generate and utilise in your home
Thank you very much for this informative video. Can I install solar panels at little height on the roof, ie by using taller beams of galvanized steel, so that I can use the space under it as a shed or storage?
Is it really profitable!
Can u show some calculation
For 5kwh setup for on grid🙏
Can we also use home inverter and on grid at same time?
For on-grid the return on investment would be anywhere from 4.5 - 6 years, based on the type of panels used and subsidy available or not.
For off-grid setup it would be 9 odd years and does not make that much sense as replacement of batt cost would be there.
About 7000 units per year generation on average. If all the units are used by you, you can recover total plant cost in 5 yrs. Panel warranty is 25 yrs and many inverters come with 10 yr warranty
Different states have different buy back policy for power. Visit your state discom policy for more clarity. But if you size plant correctly for your home needs, ROI will be faster.
Basically you need to pull last 12 month bills and sum total units and divide by 12
If that value is 400, you need 4kw. If it's 500, you need 5kw and so on
Thanks for this video sir. What chair you are using/recommend for someone who is spending more than 10 hours in front of computer.
Always informative and to the point.. Thank you Sir!
I have a few questions
1. How is Tata Power equipment and service wise ?
2. Can you short list a few good vendors in part 2 ?
3. What is the make of your current panels and how good is Waaree ?
Thank you for this and upcoming videos in this series !
Perfectly timed video when everyone is talking about solar panels
Hi Ranjit, Your video is really interactive and informational. Well I am working on solar panel installation project that take cares of end to end process including site survey to installation of solar panel. Could you pls let me know, what are the thing we check and equipment's are needed while we are on site survey for installing solar panels Specially while site survey.
What is your opinion on using Lithium iron phosphate batteries...vs lead acid that needs top up of acid and less Max power draw?
Also lithium has longer life..
Cost is more..so is it worth it?
Looking forward to part 2...
And part 3.. about maintenance
Please make more of these videos, looking forward to it.
halfcut bifacial Monoperc panel cost 27 per Watt ,Battery 150Ah - 12500, Luminous Hybrid TX 5 KVA MPPT inverter with net metering facility - 60,000 net meter cost - 12000
Please cover the details about subsidy with on-grid systems.
simple formula for selecting a solar system type(varies case by case):
1) If you are facing extreme power cuts go for offgrid system.
2) If you are facing less frequent power cuts go for a hybrid system.
3) If you have little to no power cuts go for ongrid system.
Also if you have a higher budget go for Lithium ION battery packs for hybrid or offgrid system. They usually come with a 10 year warranty and 25 year life span.
Thanks for the details. I have 3phase meter and is it good to go with single phase or three phase inverter for 5kv ongrid solar system in Hyderabad.
for a basic house hold how much power we need in general.n you please explain the maintenance cost of panel and batteries as well
My last question, if I wish to go with storage/battery, as per the average consumption (500 watts) per day, how many volts or KV I need to consider for an inverter and how much power for a battery (AH)?
The real OG tech youtuber.
Please suggest some good brands and do we need to change the wiring system of the entire house?can you also give an approximate idea about the area required for say 1KW of solar panels?
Sir, you said that your Air conditioning is working on Offgrid 2KVA inverter. What type is the AC, any specifications appreciated.
Please list out each cost in money terms also either your cost or general market cost or both to just get rough idea of cheap expensive on a personal level
Which is the best solar on grid inverter?
How is the performance of your growatt inverter
Would it possible for you to walk us through how to know the correct requirements if one is staying in an apartment or flat.
Please also talk about number of strings you have installed how the hybrid system works and why is your panels.mounted so steep im from chennai the angle is just 11 or 12 here your panels seems to be installed at around 25 to 30 degrees wont it impact production?
Hi Ranjeet, How much is load efficiency in the winter season and Summer during the night time. What is the storage capacity of the Inverter installed? Thanks
If it's a new construction, can we plan a South facing sloped roof for panels or is it necessary they have their own separate steel skeleton supporting them ?
Hey ranjit! What about hybrid ones? My ques is the excess energy generated should go to the grid which is on grid but at the same time can we save those energy in batteries before it goes to the grid(so that we can use it when the power is cut)
1.panel to our use + charge batteries first
And then
2.can it go the grids?
Is this possible??
Pls answer ranjit!!!
Please let us know about maintenance. Cause i have heard if its not cleant properly the efficiency of panel drop. Also maintenance for battery.
for 3KW is it better to go with string inverter or micro inverter.. cost difference is 62k for both from a vendor quotation?
Hello Sir, Soon to be your neighbour. Moving in to Melody which is opposite Indraprastha.
please go through each step of buying & setting up one by one
how to apply for subsidy
Pls cover the cost as well, sir . Great video
Which brands should we go for (w.r.t. every component) and pls release all other parts of this video asap🙏
very well presented.
Hey
I have already an inverter with battery installed in my house for power backup .
Now if i want to install solar system..should it be ongrid or offgrid?
What is the difference in price in ongrid and off-grid system?
What are the advantages and disadvantages of both the system when compared side by side.?
Ranjit sir, what's the total set up cost of ur ongrid solar panel also can u tell about the difference in the electricity bill after the installation of it and can we set up these kind of system in Delhi as it's a bit conjusted areas here in Delhi.
Ranjit sir Viwership is coming low because he was not making regular videos. He is one of the best in reviews
Can you please review wzatco Yuva plus projector its a budget projector i need to know your experienced knowledge about this projector please review it will be helpful to me and many others as well.
Merry Christmas
Which one is best off grid solar inverter manufacturers in India? Currently i have luminous 3.75 kva NXT
Is the net-metering system only provided by private companies or can the government distributors provide them as well? Also, do we need to arrange for batteries to store the excess power generated by the on-grid system in case the net metering system is not yet installed?
Hello Ranjit Sir, first of all thankyou for making this series to educate your viewers.
So my ques is, as you own a nexon ev, do you use your solar system to charge it up ? if you do then the power is taken from the on grid or the off grid system, i have heard ev charging takes up a lot of power, is a solar system capable of delivering that amount of power ?
Thankyou
Nexon EV is charged via the ongrid system, my off-grid solar panels are not enough to charge the car.
What about subsidy? How to avail that? And why you haven't opted for hybrid one?
Meine apne shop pr 200w ka mono panel lagaya hai with exide 1100va solar inverter & 75ah lead acid solar battery without any controller. But isme toh 1 fan bhi nai chalta hai . Morning mein 1-2 hours 100w ac fan chalta hai and evening mein bhi fir 1-2 hours chalta hai fan and 1 led bulb. Mujhe kya change karna chahiye taki 130 watt ki ac cooler subh( 9am-01pm) 4 hours and evening (5pm-9pm) mein 4 hours chal jaaye?
hi sir ,could you please make this type of edu videos on the different type of wifi networking systems like the one you recently bought tp link omada most people including me dont know about that kind of stuff please do make video on that topic.
How are you doing, @geekyranjit? I watched your video where you were talking about your health issue and fitness tracker.
Hi ranjit how to choose panel vendor there are so many vendors now how to know which solar panel company use best solar cells?
Which panel one should go for TopCoN vs PERC vs HJT
Hello Ranjit sir…are these panels delicate? What is the strength of a panel…What is the hardest material that these panels can sustain?
ranjitbhai i live in gujarat . we have 40 percent subsidy on solar panel system so which is advisable here on grid or off grid ?? for my new house
Can you make video on balcony solar system for those are living on apartment and want to use it
I am using LiFePO4 batteries with my solar setup, DOD is good. Battery lifecycle is 3000 to 6000 cycles
Please mention what are the devices you use on off grid system and on grid system like AC , TV etc., and cost per Kwt
I think you should share the expenses with us so that we can get a more obvious reason to purchase
Can you give some more insight on converting the home inverter to offgrid solar system.
Efficiency of solar system almost becomes half after some time. Is it true? If yes, then periodic cleaning will be helpful? And how to do the cleaning of the panels without any damage.
Always love the content other than the mobile phone 👍
I think you can tabulate the solar panels types, their size, wattage and energy output. It would have been more easier to understand sir in my opinion.
Most awaited video
Awesome man, I wish to get solar system installed at my house as well, unfortunately the requirements you mentioned doesn't get fulfilled. We have some shsdes from neighbours :(
Not a tech related question. What can be some suitable business opportunities for an aspiring candidate in solar field in Bharat?
I would like to know about the Hybrid solar system and how it is different from the off grid system
Do private societies allow ongrid systems to install?
Do they allow to use terrace for same.
It's my own independent house, with my own terrace so yeah they do allow but in our gated society we can put a max of 5Kva for On-grid system. If you are in a flat then they will generally not give permission as terrace is considered a common area in flats.
@@geekyranjit thanks Ranjit
Nice Video Buddy
one feedback, you spoke for like endless minutes, showing the setup without explaining what we need to understand from that setup.
may be try explaining that is off grid and what is on grid first, Give some context about the panel because to me both panel looked the same.
