great info but the background music is annoying...
Yepp, very annoying music, otherwise great video
😂😂😂
indeed … and it is actually very superficial, not really informative 🤷🏿♂️
What C said. Great info and well presented but the background distraction for anyone with less than perfect hearing ( ie most adults ) is real.
Absolutely, awful music
We have used the ruclips.net/user/postUgkxOTeIs0vv4_9B5hsmnLsk9r930uDQLu_Y for probably 30 hours with our camper and it’s been great! The noise level is really only noticeable when running the AC and other appliances like the microwave, hair dryer, or coffee pot. It’s not huge like other ones and it has wheels so even at 90lbs, I can move it!
I have 9 panels on my flat roof, angled on frames; one row of six and one of three. Initially I was advised to bias them a bit east of due south, to get the most of the early sun. That was fine for five years, but recently I moved the row of three and pointed them west of south.
It has improved the situation noticeably, as the angle of the rays gets less efficient on the six, it is improving on the three, charging until around sunset.
In some circumstances this will be worth taking into consideration. Saludos from sunny Spain.
a good video. Here in Canada the numbers don't add up, even with NG used for heat. For a 7.5kw system, at our Alberta rates alone I'd still owe money 30 years later!
Solar is definitely a different value proposition depending on your location.
@@SolarayEnergy yes the same for wind power! Im not against it, during the active times we can throttleback NG generation to allow us to use it, and as it slumps ramp up NG and other controllable sources to provide capacity.
The great thing about standards is there are so many to choose from.
Nice video, as stated before it's nice that someone actually puts numbers onto the system.
Thanks for clarifying and putting down some average numbers! Very helpful.
5 years ago, my power bills were huge, just for 2 people, so I put 5kW on the roof. 10 panels NE and 10 NW. The impact on my bills was so good, I put another 5kW on my shed. I have monitors on both systems so I can see the power curve and check they are working correctly. These systems have now paid for themselves, and over the course of a year, my power bills are zero. I have just paid my winter bill of $400, but I will earn that back over summer plus some. Putting PV on the roof was the best thing I have ever done. I monitor the performance of my systems weekly.
Hi mate,whats PV? Thanks
How much was your system?
Simple straightforward and to the point. Thank you Sir. Now I know what I just purchased.
Happy it helped Alexander!
Nice explanation that may give people a realistic idea of what really goes on. For the difference between Kw and Kwh, I like to use the analogy of miles and mph, or, if you prefer, km and kph.
You can also use the analogy of eating a bowl of ice cream (or soup, or cereal). Lets' say you're using a teaspoon, then a single spoonful is a teaspoon of ice cream, but over time that spoon will keep delivering spoonful after spoonful of delicious ice cream, so the spoon is the kW, but how much ice cream it delivers in that 10 minutes of joy is the kWH.
How fuck stupid you people are . Stop breeding
Thanks, now I know I should be able to het by on 5kWh system based on current usage. Simple and to the point.
Very important to know the difference between power and energy
Power is energy divided by the time it takes to generate it. You're welcome
My 5KW system, using Enphase micro inverters has put out in 8.5 years 70.12MWh of power. I figured out the exact number of days (3099), and that is about 22.62KWh of power per day, or 8.26MWh per year. That's in California, a real 5KW system, and what it really puts out, based on weather, temperature and all the other factors.
Am still confused with these ratings. So what battery ratings ratings do you need for such because am seeing batteries rated in KWH
It should be70 MWh of energy.
Thanks for I information. My 10 kw system generation at south India city Coimbatore for a year is 15 MWH of power .
Astro Steve Thx! I’m about to purchase a system now. What panels and what inverters did you use? I was offered 370 watt panels but only Iq8plus inverters which have a Max continuous output of only 290 watts. I was worried about too much clipping. Did your panels and inverters have that much difference in ratings?
Anything you would have done differently?
Thanks for the info.
-Travis
@@maddeusdoggeus1 I have 250 watt panels with the Enphase M215 (215 watts max). If I remember right, it can actually stretch to something like 220 watts. I've only seen clipping on one day - ever. My roof faces south exactly I should have mentioned in my original comment. For 2022, Yes, the IQ8 inverter from Enphase is what you want. Their ability to make power if the utility power goes out is awesome, without needing super expensive batteries! As long as the sun is shining, and the home is using less power than your panels can provide - you will have power. I am seriously looking at adding a few more panels, and possibly upgrading my existing M215 inverters to the IQ8. Good luck!
🤝Thank you for sharing this video.👍👍 Keep up the great content!
Great explanation thank you
Great Info video, Tanks
Well done!! great video
A kilowatt hour is 1000 watts of power being used (or generated) continuously for an hour. Given a microwave oven rated at 1000 watts, a kilowatt would be the power required to run that microwave oven at full power. A kilowatt hour then, would be the energy needed to run that oven at full power for an hour. The rest of your explanation was clear, lol!
Great info... Nice bro... From India
Nicely explained
Great information. The background noise...not so much. Thanks for the information.
Nice explanation 😁
You only use electricity for lighting at night when the sun does not shine. You use more electricity in the winter when the sun does not shine
So understanding the technology, and understand what you use it for, puts you at an advantage. For example, I know that I would like to stay cool in the summer... mostly in my bedroom where I can sleep. My bedroom is a 10x10' room with a 9' ceiling. a 5000BTU window A/C would work, or even a 6000BTU would be great. That uses about 500W/hr. So, I would need Solar Panels to cover that range. Or at least a battery to store that power (because I care mostly about the night when I sleep) and Let's say I get about 8 hours of sleep... even 10 hours let's say. So that's 5Kwh for 10 hours. I would need a 6Kwh battery to have the A/C constantly running for all 10 hours. But the AC is probably climate controlled so your room doesn't become an icicle. So Of that 10 hours, it's probably only running about 65-70% of the time, drawing from your battery. So, that means: I would need 3x250w solar panels, + 1x5kw battery, + 1 2kw battery. Santan sells used 250w panels for 50 a piece, 5Kw battery is about 3500 on amazon, and a 2kw inverter is about 200 bucks. I can have a nice cool summer for many summers to come without using any extra electricity from the grid for under 5K. (3500 batter+150 (maybe about 50 of shipping)+200 for inverter+500 for cabling.) Off Grid living baby!
Figures agree with my installation..Average currently 20.7 kwh. Output drops slightly during extremely hot days but a fair breeze will improve output.
With what size system ?
In 2014 I bought 15 panels at 260 Wp each, totalling 3,900 Wp. They are mounted at a 50 degree angle, straight South which is good in the Netherlands (53 degree North).
The inverter measures the output and the 3,900 Wp results in an average yearly energy harvest of 4,000 kWh. The Wp/kWh per year ratio is slightly over 1 which is the best one can do over here.
The power output of the panels mid day is about 3,000 W with very seldom peaks of 3,500 W for only a few minutes on a sunny but chilly day in the spring.
We are lucky here in Australia that our climate makes us so well suited to get maximum benefit from solar!
@@SolarayEnergy True. However, the geolocation of the Netherlands also has the opportunity to harvest energy with windturbines at the North Sea.
A 1 MWh wind farm at sea and a 1 MWh solar farm together, produce a 0,9-95 MWh complementary output without batteries.
So every location has its advantages and drawbacks. The good news is that we can get rid of fossil fuels.
3:32 That is rather optimistic for me. My system produces about 6000kWh/year. So the location is very important too.
Location definitely matters. These figures were based on a home in Sydney, Australia.
How much sunlight are your panels getting?
I'm purchasing a home that has a 25k kwh/year system. It's got a big system because it's a Arizona home. Hopefully it can keep up with the hot summers
Very interesting☀️Energy!
It appears my previous calculations are correct. I would need a system of around 15kW in size to produce the amount of electric my home uses on the average day in a peak month. (Approximately 70 kWh per day).
About 20kWh a day where I live. (Gold Coast, Qld)
I don't know how much my neighbor paid for roof top solar panels, but he is not getting what he paid for since it isn't pointed toward the sun. If I were to guess, it is 25degrees from ideal direction.
Where I live, power is less than $0.06/kWH. Solar is more of a solution for remote areas, or where paying for installation and distribution don't make sense. Works good for out buildings like a garage, especially when a service upgrade would be required.
my 3.2 kW system gives about 20 kWh on a summer day and about 10 kWh in the winter. Wish we had installed a 5 kW system to begin with
My 10 kW system gives 50-70 kWh on a summer day (1300-1400 kWh/ month) and winter zero (if it is covered with snow) in Finland! And now 2022 when energy prices are high I got over produced part about 20-25 cent / kWh (Euro) and I am not complaining! I wish I had roof for 20 kWh system, but no!
Thank you so much for your video. You took your time to give us some good information. However, it's not one size fits all. Some areas give you more sun in 24h & others don't. Some feed the grid others don't. In many cases, people try to have as much energy as they can effort, from as many panels and batteries, regardless of whether they use it all or not.
Thanks
I Hate it. Grid power even using solar is still causing the individual to be reliant on someone else and must Pay that someone else for what could be theirs alone. I'm all for No Grid and individual homes with solar, wind, geothermal and hydroelectric. This way if the Grid goes down, all will be happy warm, and have good clean water and food because they won't be part of that grid. Cities should allow anyone who wants to run totally off the grid to do so.
@Anna S It does not, you will have power. As long as you have a way to make your own electricity from solar, wind, geothermal or hydro electric, you will always have power even if the cities power grid fails completely or a tornado rips down their power lines. This is because the power you create is stored on your own property in batteries you buy for this purpose. It doesn't need to be connected to any grid power at all. They are two totally separate systems.
If you only do Grid Tie then yes when the power is out your solar goes down to prevent power from back feeding into the grid but... Things have come a long way and you can get very good Hybrid inverters and really good Lithium Iron Phosphate batteries that can be combined into a pretty compact system. With batteries your storing all the excess Daytime energy for use at night. You can see your electric bill drop to a very small amount or actually zero if your system is sized right. Check out Sol-Ark 12K Inverter and the Fortress Evault or Eflex batteries. It works during power outages and can be used as an On Grid or Off Grid system.
@Anna S many systems are wired that way so you don't feed power back to where say lineman are reparing but you can have it wired to disconnect from grid but switch on your home. but without batteries you only have power daytime . much like when people have generators. there's auto and manual switches
Nikola tesla was all about giving us free energy and look where we are now!
the grid should be subsidized as a public works project for people to share their surplus, locally generated energy
good explanation
Very informative video. Greeting from Angola, Lobito.
We're here to help make the information easy to understand.
@3:08 I realized that this video must be made on the southern hemisphere. 😂👍
Yes, this is for Australia. Just stand on your head and it will make more sense. 🙃 Hopefully, it helped nonetheless.
I have a 4kw system on the coast in central California and I produced 3054kwh last year. Edit: I misread the data my actual total production was 7467Kwh my usage of solar was 3054. The rest went to the grid or battery. I also used some power from the grid, because I have a minimum charge so I try to use 2Kwh from the grid everyday to minimize my costs.
I have 4 kw system in England , produces 3700 kw/h per year , yours sounds a bit low, maybe you have shading issues, ask electrician. His figures of 20 kw/h per day for 5 kw seemed quite high , maybe air quality or sunshine better in Australia, well it is sunnier in Australia. You're in California so should be sunny there too.
@@pinarellolimoncello There are a lot of factors that reduce maximum yield and I have several of them from not being aligned due south, inclination angle, partial shading in the late afternoon from a chimney, to not cleaning the panels last year. But you got me thinking enough to recheck the numbers. Apparently I miss read that data and my actual production was 7467Kwh. The 3054Kwh was how much solar I used, the rest went to the grid and my Power Wall. What really made me question my data was when you said daily yields of over 20kwh were unusual. On sunny days my yield in the summer months are usually in the mid 20’s sometimes for well over a month straight. When my panels were new and cleaner they occasionally got into the high 20’s. Never did hit 30 though.
@@matthewhuszarik4173 That is impressive, think I need to move to California . I do get yields in the 20's, think 28 was most I've seen but average's bring it down and our weather here nowhere near as consistently sunny as California and Australia. Makes an even better case for installing solar in places where there is so much sunshine.
@@pinarellolimoncello Yes we live in an ideal area for solar. Along the coast far enough away that we don’t get the marine layer, but we do get the moderate temperatures. One thing I have found interesting is I have yet to get a day without any production. This year so far my lowest production is 4.2Kwh last year I did get a couple days around 0.5Kwh. Last year I had a couple two day periods where I only generated about 4Kwh total, but this year nothing yet close to that with the lowest 2 day total of about 15Kwh. In the last 2 years I have only failed to fill my Power Wall 11 times from my generated power, but I do manage it so I use ~2Kwh a day of grid power, because I have a minimum charge/day of $0.35 whether I use the power or not. So if I was only using solar I would have had another hand full of days where I didn’t fill my Power Wall completely. So far I have been happy and my solar and Power Wall have completely eliminated my electricity bill. I generate enough surplus power to pay for my minimum charges.
@@matthewhuszarik4173 I used to work for a solar install company and a good friend of mine on the company installed the first power wall in England, had a few issues to start with but it got resolved amicably . My thoughts are whilst batteries have a place wouldn't it be simpler to just have credit and debit system with the grid minus a small commisSION (SION>>promised land) . The grid acts as the battery, everything you put back in the day can be used by business /commerce /other people but the domestic consumer owner gets to take back units at night from electricity provided by coal/nuclear / wind, minus a 5% handling charge. This would reduce the demand for expensive batteries and encourage consumers to invest in solar and take responsibility for their usage in daylight hours, they may want to run a washing machine / fridge etc but not leave the tv idle simply because energy is free. Everyone becomes a producer / provider, thus surplus energy results in lower pricing until a balance point is hit where its not worth the investment, the Holy grail of economics. The competitive nature of man means people will then seek improved panel efficiency or more energy efficient electrical goods. Is simple simple stuff and only held back by putting up stumbling blocks to common sense. Elon Musk can still sell batteries to people in remote parts of Africa or Nepal or disaster struck places like Florida at the moment, community solar plant where people can charge their phones etc.
Very good information and nicely presented.
I think the kWh produced by solar panels needs to be reduced by about 20% when that is converted by the inverter to AC though. No?
@@garysmith5025 - thank you! That is rather reassuring.
Great presentation. The music is a tad too loud.
Good information and i had a dance!
What kind of internet system to use with solar
Hi correct me if i'm wrong. A 5KW solar panel system generating 20KWh daily would mean an average of 4 "sunhours" at the spot its installed in correct? So if one stays near the equator where 5.5 "sunhours" @ 23-33 degrees C are typical conditions it could generate a higher daily KWh then?
Indeed. More sunlight means more energy converted
I have 9660 watts and live in Arizona not a bad situation.
South India my 10 kw one year solar plant generate 15,000 + (kWh ) units
Can you recommend a reputed & trusted company who can do a full roof install of panels & install inverter & install a Tesla PowerWall3 (or two) in upper north Melbourne (Cragieburn, Kalkallo, Mickleham) area - on a new house build? Guessing you only do installs in Sydney?
Unless u are an excessive energy user n own electric cars with a very low "fit" .
Its not financially viable for a battery atm 02/21.
Here check out the numbers ruclips.net/video/veZmzeHnTvs/видео.html
Hmmm- What about the months of January and February in central Wisconsin where the sun barely shines at all? Or the cloudy months of April through June? Or are you ONLY talking about grid-connected systems? Are you also keeping up with the power companies that are constantly cutting back on "net metering"?
the music is too loud
Nice explanation 👌 however if you have batteries then won't this change? A video on battery combined and optimised quantity would be great.
Good suggestion Dan. I'll add it to our list!
For batteries, you have to estimate how long you will be without sunshine, and what power you need to be drawing and for how long you will be taking electricity from the batteries. That will help you size the batteries.
Then there's a second part to it, which is how quickly do you want to charge the batteries up? And that determines the power rating of the solar panel installation.
And that is going to depend on a number of factors such as: the duration of the periods of sunshine the panels are exposed to in your location, the capacity of the batteries.
And the brightness of the sunlight comes into play here. Under cloudy conditions the solar panels will not produce as much power and you may decide to double or triple the power rating of the panels, or even more to compensate, so you still get a suitable charging current to the batteries.
I do not understand a thing .. Why it is named 5kW system if it's producing 20kW per hour ?
Ty sir
100 watts at a 90degree angle at the equator. (standard rating). I live at 72 degrees north. I can produce a maximum output of 72watts at a 90degree angle. Factoring in earth wobble and non perfect tracking I average about 50w per 100w(rated)when the sun shines.
The figures provided in this video are based on panel performance in Sydney, Australia. Certainly these figures can vary depending on your latitude etc.
Here in West Aust, they pay 2.5 cent kw for exported power then charged you for the power you use @ 27.3 cents + gst kw ,so not even worth thinking about solar unless you have battery storage.
The main benefit of solar is to use it as it's generated to directly reduce your power bill. In the good old days we'd help people size up a system to match their daytime energy consumption, these days almost everyone sizes up the system based on their 24-hour usage because they will be purchasing a battery within the lifetime of the solar system. The feed-in tariff no longer matters now that we have battery storage, as you say.
@@SolarayEnergy Are you sure that's how it works in WA? I have 20 panels and my Dec bill for 59 days says I exported 1222 kw/h and imported 408kw/h. I am home all day so use power all day , just seems a lot of exported kw/h if I am using the solar as well? Maybe its setup to export everything and then we pay to import it again? it is Government owned Power company lol.
You could dump the excess in a storage heater.
Ok, to export power to the grid requires a higher voltage. For a single phase installation the maximum output voltage is 258V. If the equivalent grid voltage reaches 258V then your inverter will reduce output so as not to exceed 258. So, you can either use the power yourself directly or feed it into batteries.
That's absolute BS - at least here in the UK. You export power when you have excess - at around 240V as that is what the grid is rated at (or SHOULD be). Feeding power to the local 'sub-grid' at the normal voltage will power properties on your 'local' (downstream of your local substation) network. If your grid voltage goes over around 248 - 250V then your inverters shutdown. Why? Because the grid provider has the ability to push the voltage UP to signal that all grid connected PV (and wind etc) systems MUST stop producing as the network is in maintenance mode - they push the voltage high with a low power (amp) load so they can work on / test parts of the network without the risk of frying the staff who are working on it (I have VERY explicit experience of this). The opposite is when the power goes off from the grid - and your inverters shut down (same reason) - they need to be able to work on the grid without getting fried by a bunch of solar generators etc. pumping unexpected power into what is expected to be a safe distribution network. This is why a Tesla Powerwall will disconnect you from the grid when it goes into backup mode..
@@ukgroucho I’ve tracked system voltage with inverter output on a sunny day and my solar supplier was absolutely correct.
@@ukgroucho You seem very knowledgable, i use 6000kwh annually according to my electric bill, does this mean i would need a 6KW system to outweigh my electricity? Its very confusing
@@welshe222 So your average daily use is about 16.5 kWh (or 'units' as it is often referred to). I use nearer 20 kWh on average per day. My system is 8.5 KW. Throughout the summer I generate FAR more than I can use on most days - sometimes as much as 50 or more kWh per day - so even though we will try to do high current draw stuff (washing machine, dishwasher, oven etc.) during the day we still export a bunch. This June and July we generated nearly 900 units per month and exported around 40% of it. When we eventually get electric vehicles (one EV and one PHEV ordered but not due until early next year) we will be able to time charging them to make use of that extra stuff we are generating. We were mostly self sufficient from May through to end of September but there were some days when the weather did not co-operate so the Tesla Powerwall was not full charged and ran out overnight (well down to 16% remaining which is the default that it holds onto) so we used a few units overnight. The challenge is that once the days get shorter and the sun gets lower and you get more cloudy days and you start running off the battery earlier in the evening and later in the morning you simply cannot generate enough to run the house (unless you had a HUGE solar array and batteries) - so, for example, yesterday we only generated 6.9kwh, today just over 9kwh, but Monday 19.2.kwh so we were pretty much self sufficient. As we get deeper into Autumn / Winter I know we will have days when we generate pretty much nothing. The 'bigger' picture is what happens over the course of a year. Last year we used 7360 kWh... 31% came directly off the roof, 32% came from the Tesla Powerwall (so generated, stored, used overnight etc.) 37% was off the grid. So 63% self powered. We generated about 7100 kWh. Also worth noting that the Powerwall doubled the amount of power that we generated and were able to use rather than export. Wish I'd added the Powerwall sooner - only had it since January 2021 and the array is nearly 10 years old. To answer your question specifically, you will not be able to (economically) install enough solar PV capacity to eliminate your need to use grid power - unless you drastically cut that 6000kwh number down. Even then there is a balance between having enough generation capacity to run the house / charge a battery to run the house when you are not generating and having so much capacity that you are exporting huge amounts in the summer - a costly path where I suspect the payback would be long. Plugging the energy generation gap in the colder months is the challenge, I have looked at vertical axis wind turbines but I really can't find a product that looks like it's a good fit. OK long answer... if you have more questions then post and I'll try to help.
@@ukgroucho So essentially i could get away with a 8KW system to at least bring my yearly bills down an incredible amount, thats all im really looking for honestly, not 100% offgrid type of system, just bring the bills to more acceptable level, right now we have a bunch of extra stuff running 24/7 so i suspect our usage is quite high, 3x freezers, 3x fridges etc, essentially my entire house is not eco-friendly right now, but i want to get more green so have been looking at options, And i thank you for all the information you provided, I only noticed on this yearly electric bill that it even says howmuch electricity i used "5999kwh" i believe is what it said, It did say "annually" and not any sort of monthly calculation or weekly or anything, so was confused on how to convert this number into the type of system that would balance this usage out, So thanks for your help, its much appreciated.
What about seasons , height of the sun,
No one is talking about what inverters and the ratio you are using. This matters very much
This video refers to average performances for a 5kW system.
You are absolutely right that the inverter plays a big part in performance. We only do installations with Enphase Microinverters or SolarEdge inverters with DC Optimisers as these will help your system perform better than with a regular string inverter.
If a person doesn't know the difference between kW and kWh, then they shouldn't be anywhere near a solar power installation.
Only had solar for 3 days in the uk. 5.2kw system generated 33.6 kws for the whole day on its 2nd day
Nice!
You should tell us what country you are referring to
HOWdy
Thanks
COOP
...
Interesting.
Was expecting real data , instead of anticipated energy output number
The film is over complicating things. How many sun hours you have, how many 100% sun hours you have? That is region depended and that is telling you how much output you get.
Good and informative video but the accompanied music is so loud and annoying
ah, hell, I am late to this video, I do hope you are still answering comments.
Please tell me how you get to 20kwh from a 5kw system, I assume this has to do with a lot of averages; like daylight hours, location, etc. I would like to be able to calculate this broadly when looking at property.
I assume the rating of 5kW, relates to what it could generate in one hour in perfect conditions. Most of the time, it is somewhere to 2kWh. So, let's say you have a 10 hr of sunshine per day, there you get 20kWh.
It's impossible to give a reliable average - as DS says above - the wattage rating for a panel is in perfect conditions. That panel may perform very differently mounted on your roof, or on my roof because we live in different places and where the panel is mounted makes a big difference. You need to look at things like the direction your roof faces relative to the sun during the day, the pitch of the roof, is there anything that can block the sun like trees etc. All make a big difference to the performance. As does the time of year - in the Winter the days are shorter and the sun doesn't rise so high in the sky (and as the sun shining at 90 degrees to your panel is the ideal, this makes a difference) so even on sunny days in Winter the electricity generated is less than on a sunny day in Summer.
I have a 3.15 Kw system in Southern Spain - my average daily production was 13.17 KwH over the year, but this varied from 8.65 KwH per day in January to 18.83 KwH in July - essentially your annual production follows a bell curve with the high in your Summer and low in the Winter - but someone who lives in India might have a different pattern because of their monsoon season. Also you need to remember that these are averages - so if you have an unusually sunny January, or cloudy July that will mess with your numbers.
When you look at a property you need to look at which way your roof faces etc. The other thing to think about is how you use your energy - if you are at work all day and your energy usage during the day is low then you will probably be selling a lot of energy back to your supplier - so, financially, how you're treated by them will make a big difference to you. If, on the other hand you're retired or work from home then you'll soon get into the habit of running your appliances in the middle of the day when your solar energy production is at it's highest - or use timers if you're at work.
There are the numbers and there are sunny days ...So, it depends on the weather ,I guess ?
PLs reduce the background music to the minimum.
So how much does a 3Kw solar system produce in a day if you say a 5Kw solar system produces around 20KwH/day?
Around 12kWh/day.
solaray.com.au/price-3kw-solar-system-cost-benefit-output/
5KW X 1400 hrs per year = 7000KWH/year = 7MWH per year
was i correct ? right on james
I have a 4.8 kw solar system, its pretty sufficient for me . With the exception of an A.C which i don't need coz I live in a moderate climate place, I power everything in my house, i..e oven , induction , fridge, rice cooker, washing machine, dish washer, water heater or geyser,etc in daytime and in the night , I used only the Tv, fridge , PC and the led lights . I even charge my electric scooty and also slow charge my electric car on sunny days.
Do you have a battery to store the energy not used? WHat is your daily usage? I use about 9.4kWh per day.
@@DS-pk4eh I have 6 lead acid battery 150 amps each connected to a 5.5 kva 220 volts inverter. I use about 9kw - 15 kw in a day
@@sony5244 Nice setup. So you have 33kWh of battery capacity? Or I miscalculated?
@@DS-pk4eh I have 6 nos 12volt x 150 amp tall tabular lead acid batteries connected in series totalling 72 volts.
@@sony5244 OK, thanks Sony. So, that would be around 10kW, enough for at least one day without any kind of power but batteries.
How could it make more than 5kW? It's always going to be less. You should always be around 1.15:1 DC:AC power.
You guys are so lucky. In South Africa we get 0c for pumping into the grid :-( How is that for motivating people to go green?! And now they are talking of taxing us per PV panel. Going green is a sin in South Africa. Government even put heavy taxes on all green products that comes into the country.
Feed-in tariffs used to be much higher, but yes - comparatively we are lucky to get one at all!
Governments should be making greener products more accessible, not less! We are fortunate to have government rebates towards solar installations in Australia to help make it more affordable for families.
@@SolarayEnergy that is great. Governments are directly responsible for these plans to fail or succeed. What can I say, when corruption is all they are thinking about how can it be any different?
Thanks again for the great info and video.
@RepublicanGuard I don't have enough money, because I'm too old now for a job hunt 😀
Those numbers are pie in the sky numbers, I'm calling B.S. on that!!!
Certainly optimistic and under ideal circumstances!
This is in Australia 🦘 ya clowns lmfao.
@@USNEM Is the sun different in Australia? The only way to get full power out of any solar array is with an auto tracking device, PERIOD!!! And even with that, these numbers are pie in the sky.
I'm not sure where the 5K system producing 7.2K is located lol. But here in the Netherlands my 7.2K system produces only 4.8K.
In Sydney a system produces about 4 times its size so a 5kW system will output 20kWh a day, on average, doing more in summer and less in winter.
And now children lets talk to Mr Killowathour
the speaker omitted the only needed facts one would consider in such a project? what is the average 4 member family Kw usage over one year, period? many folks seek an 100% off grid system so his inputs are void for them? there is a balance in solar energy between generation peak power, and usage, peak load, the idea is to keep the well 1/2 full at all times. so how is this carried out?
take your electric bill add all 12 months together divide by 12 divide by 30, that is how much electric you use on an average day. whatever that amount is measured in KW that is the key point to build a solar system off of, think of it as a point of beginning . so your collection device a string of solar panels 12 volt run by 48 volt into the all-in-one converter will receive this flow of electrons and manage it as the demand put on your domestic service is used through out the day. the inverter is programmable or set it on auto function meaning the box will channel some energy to the in home grid panel, some will go to the batteries, some may go to the neighborhood grid sold back at a 1/3 your price rate! lol
The average daily power usage for an Australian home is 17kWh.
Very few enquiries we receive in metropolitan markets are for off-grid systems. This video is definitely not aimed at off-grid prospects - not many households would find 5kW systems suitable for this purpose.
7300
This is great!
Most people have no idea about the difference between energy and power.
Or the physics laws behind all this.
So that’s why you can sell the stupid public everything!
Stupid works both ways. A stupid consumer may buy an overpriced system based on false promises and fail to recognize the lower value received. But another stupid person may be looking at a system priced well, a good value, and have the need, but still not understand or believe good promises, and therefore they don't buy the system that would help them.
Nice video, thanks. Can you help me calculate how much electricity my water pump consumes per hour. I use a Wizz mini motor made in Italy. 220v.....60Hz....3450min'......0.37kW....0.5Hp
i think it works like this .37 x hours used .but with motors they draw a lot of watts to start motors are harder to calculate use. you can have watts to run but not enough to start them.
Your motor, when running for an hour, will consume 0.37kWh (kilowatt hours)
3:08 I kept scratching my head, trying to figure out why that graph was inverted... then it hit me, you're from Australia, duh! 😅
Things are different here in the land Down Under! ;)
I thought it was 15c not 25c
You cannot run a house from a 5kW invertor. Spend the extra money an get at least an 8kW. You only need a huge (over sized 10kW preferably 20kW) lithium battery and a few panels 11 to 15 with a 8kW and thus use 100% of the power produced yourself. But first look at where you can save. Don't listen to people trying to convince you to go Gas? You will never get that money back in a lifetime. Rather use the money for a bigger battery. Get an induction stove, air frier and good induction pots and pans and problem solved. The other secret I will keep for myself. First want to invest in the right company
I use very little to no grid power.
20 x 365 is 7300 :)
Lucky if you get 12 kwh on a constitent time frame
Either am stupid or the manufacturer of the panels are lying , it’s 5kw as it states
3:43 gevin that tesla battry is 80kw this means that the 5kw system producing 7200 KWH per year can charge tesla battry 90 times in one years . which make it payback for install cost on 2 years only ( calculated based on price of install and gas here in egypt )
Very unlikely to charge from 0%, likewise unlikely to charge to 100%...
I’m gonna say….5 kilowatts!! 6.7 horsepower!!
Get rid of the back ground music
Stupid music spoils this
No
Background music is ANNOYING!!!
Is not
500w average.
Always is 10% of what’s claimed. Tops 16%
Just remember when you put a solar system in for your house, unless you willing to pay lots of money, normally the system will help you reduce your power bill not cover it all, so if you normally paid $200 for the power bill. After solar installed, you should see you bill reduced. Still better than nothing.
Why can’t you use more panels?
@@delatroy some places will only allow a system to be but so big. 20kw system is the largest allowed here.
I really want to watch this....but whyyyy does every video have to come with chirpy guitar music? 😫 I'm not just whingeing. It really gets into my head. Perhaps just the problem of a sensitive person but there you go...
Hi A B,
We've taken that feedback on board - you'll be happy to know that all our videos in 2022 have a backing track that is a lot more subtle and soft.
ultra distracting music :( polluting good content
Turn the ******y music OFF - jeez - this is supposed to be a serious discussion !!!
I want to listen to YOU - not some wallpaper jangling noise
We know, we know! We have not put music behind our more recent videos. Lesson learned!
We hope the information was still useful!
Power is energy multiplied by time
