@@freddymax5256 Many people think lowering taxes is good (it is debatable if that is true, given that the US has run a large deficit for every administration after Clinton). Instead of giving tax breaks to mostly those earning over $1M, things like the solar tax credit gives a tax break to incentivize a shift to lower cost energy that reduces the overall energy costs on Americans. That is, this is a productive tax credit, and more accessible to all Americans rather than just the wealthy. Seems like a good investment to me...
A pretty good video. But here in California, what I see is that the utilities are doing everything they can think of to block customer solar. In the earliest days, the Utilities simply were not doing anything about climate change. Schwarzenegger started the solar ball rolling and left office in 2011. It took awhile, but the citizens took up the task of adding solar and inverters to their rooftops hear and there. Not many rooftops offer good solar exposure. He even made it necessary for southern side neighbors to trim their trees if they shaded their northern neighbor's solar. That law was soon modified to protect existing trees. Up until 2022, rooftop solar grew nicely. But then, what we see is that suddenly grid scale solar grew in the deserts, exceeding rooftop solar. At the same time, Newsom, the CPUC, and the utilities made a big move to kill NEM2, which gave full energy and monetary credit for summer and day solar to be used at night, and even transferred to the winter. New solar customers had to have batteries added to their new system in order to get their money back. The utilites were only offering maybe 5 cents per KWH for solar shipped back to the grid. ... The competition became who gets to dump their excess solar power onto the grid? NEM3 gave penalized rooftop solar. They also wrote rules to make every solar installation go through a single meter, and every separate dwelling to have a meter, killing the ability for customers to have mini-grids of their own. Business, schools, apartment buildings were all penalized. The rooftop solar business was crushed! Hence the statement that only the big solar companies survived was because of corruption.
@@callmebigpapa God only knows! Such i ssues seem to be determined at the state, county, city levels, with no clarity. But even with solar and batteries, back-up is needed for cloudy days.
Free nights from 8 pm to 6 am works great for me. My batteries recharge at night and are charged during the day with excess solar. My batteries carry me through the morning till the sun gets high enough for solar and carries me through from late afternoon till 8 pm I’m paying around $7 a month to be hooked to the grid.
I think environmental legislation in the USA gives China a massive foot forward in dominating the lithium battery market for the time being (Unless Sodium batteries become the new norm). Cost per kWh of storage is way to high in the USA even with incentives and subsidies for it to be used at a residential/utility scale.
@jackthesolarguy there's no excuse for the problems I encounter on American assembled and designed packs. Most of the American ones I reviewed years back are out of business because their products were either a fire hazard or had endless issues. Not talking about environmental legislation here. Talking about the actual device
Sodium batteries became available last year. They are still expensive, but prices are expected to drop significantly. This could have a significant impact this year, or next year. Vertical integration is not always done well and it's not always necessary. SolarEdge offering batteries doesn't mean you have to use their battery if you have their solar system. Other brands can work with SolarEdge systems and they offer a UPS function, where SolarEdge does not. And they are cheaper.
That makes a lot of sense and should be happening, though most people plug in their cars when they get home from work at 5-6pm which is the worst possible time to do so.
Itcwouldn't be hard for Musk to set up programming to limit charging times and rates inside the cars he makes to encourage better use the grid power but he'd cry foul/discrimination/bad impacts for his industry/etc.
When talking about the duck curve you should current data. In 2024 with an addition large amount of battery storage 3-7 Gigawatts have been lopped off the head and tail of the duck curve. The amount of storage should increase another 25% by spring of 2025.
I have had solar panels installed at my house for 3 years. Decreased my electric bill immensely. Used to pay 800 dollars on a bad month in the summer. Now the highest bill is 300 and usually about 50 bucks. And that was before buying 2 electric cars and getting rid of my gas car which cost 300$ monthly gas bill. Could you comment on the new hybrid panels offered by Oxford industries. I believe they offer >25% efficiency. This will go a long way to make solar even more attractive.
Im working on a jackery 5000 with a smart transfer switch. The goal is portable power for 5th wheel travel power. Then when home using it to offset power at home with solar.
Excellent overview! I'm baffled by the 'Virtual Power Plant' payment, as mentioned at 9:15. Isn't paying $2 / $3 per kWh a boon for the homeowner, but unaffordable for the power company? At least where I live, $2/kWh is several times the price that the power company charges, even at peak periods. What am I missing for this to make sense?
We have such things in Australia, and adoption is being encouraged with battery subsidies (we already have 40% domestic rooftop solar). In our case, the energy company agrees to pay for our exports (17c 1st 10 kWh, 6c thereafter) and have access to draw on customer batteries when there is a generation deficit causing prices to rise dramatically on the NEM (national energy market) Energy prices go negative almost every day from 11-3pm, but there can be massive increases between 6-9pm. Bring able to draw from thousands of domestic batteries at a rate of 5 kW each allows them to avoid extreme pricing and still pay the feed in tariff. We also have an energy company called amber who offer dynamic pricing for both consumption and exports. At this time of year our battery is fully charged before 10am.. 10 kW panels and 27 kWh of storage eliminated our energy bills all year
@@jackthesolarguy Thanks for the reply. I've never heard of VPP, even from those I know who have solar installed. As best I understand, the agreement they had (years ago) was pretty simple..(e.g. we'll buy your surplus electricity). Based on your first sentence, should I infer that a power provider's purchase of surplus at $2/kWh actually IS viable, given grid limitations and limitations with 'peaker' plants?
"The duck" is specific to certain points in USA (or int the world). It might also be affected by the amount and size of solar systems... if many people have "oversize" system, the production at mid day is too high and they export. In Finland in the winter half of the year - a common day has "free to very cheap" electricity 01-06 then a small rise rise 7 and 8-10 when everyone wakes up, and companies open and factories start we get a peak of higher prices, then slightly lower (still high) during day 11-18, then varying 19-21, lower 22-24. In the summer prices are in general cheaper overall.
That all SOUNDS GOOD, The average system for any up grade is 9 YEARS TO GET EVEN, that's paying cash. This industry is the shadiest of all, next to used car sales. Never a straight answers, especially the big companies. I have been doing my research for 10 months. The average big company marks up equipment by 100-300 percent.
Most solar installers are only aiming for 10-15% profit margins on any given installation they sell. It is a volume business with a lot of competition. Where you need to watch out is with financing fees and different lease options that many of them sell nowadays.
There are companies who let you DIY by designing a system for you that will qualify for grid tie and credits where possible. Then it's up to you to decide where to buy the components from and who to use to install - or even do it yourself where legal. But I agree when you look at the costs of batteries and panels you can buy that stuff for far less even at retail prices, let alone at commercially. A huge part of what you are paying for is install labor, design support, marketing, warranty, and all their business costs before they even turn a profit. That's why a system can cost $2 per Watt vs panels costing well under $0.20 out of factor.
@@enmodo That’s correct. With most residential installations, the equipment will not exceed more than 50% of the total installation expenses to the installer. The bulk of the project expenses will be labor, permits/utility fees, insurance, and engineering plan sets. If you have the time/knowledge to install the project DIY and source the equipment yourself at a reasonable price, by all means.
It costs a LOT (per kWh) to store energy because of fixed costs of the system only being needed a few hours per week. Plus there is 7-20% (rough estimate) of energy loss to push the power around the system.
im a 66 year old man. I USE TO WORK AT A POWER PLANT IN ARKANSAS (ENTERGY, WHICH WAS ARKANSAS POWER AND LIGHT, CO BEFORE ENTERGY BOUGHT IT) . i can honestly say that I WOULD NEVER HOOK MY SOLAR TO THE GRID AND SUPPLY THE ELECTRIC COMPANY WITH POWER!! NET METERING SUCKS!!
It will take a while for the production of the solar components in USA to be established so importation of that will continue. Tariffs will be applied and cost will go up in the short run. For how long, that is uncertain.
If you study tariffs through history, they always fail to accomplish their stated goals and in the bigger picture cause more economic harm than good. We absolutely should be making solar components here but only if they're price competitive without artificial support.
I have a question. Are solar farms making money? Say a person has a large piece of land. Could they put hundreds of panels on the land and alsi batteries and sell the power to utilities at evening time? Do solar farms make good money?
Government subsidies and tax savings from accelerated depreciation make them profitable projects for the corporations who invest into them despite the costs
I was an early adopter, and my system needs some upgrades. SCE just kicked me off NEM. I have been unable to find a local contractor to help, and am thinking about buying panels, batteries and equipment and installing with the help of an electrical contractor friend. I am a bit above my pay grade, but??? PS, thanks for the good insights.
Can I use a battery when PG&E rates are lower to charge? The cost of total reroofing, panels and Batteries are out of my reach. I thought why not just use batteries to keep me my usage lower during high usage
You can do that, however battery-only systems do not pencil out for financial savings. If you are with PG&E, it is best you offset as much power as possible with Solar, and use the batteries as a means of powering the house during non-solar hours. If you have enough roof space the payback period should be sub 9-12 years.
A consumer off the shelf battery system will cost you $$$. But even a DIY system with a 10kWh for under $5K just doesn't pan out unless you can save big. Even if you saved $0.20 per kWh using a battery that's only $2 a day and takes nearly 7 years to pay back - and that's before you add a grid tie inverter/charger adjust for loses and add more $ to get it approved to hook up. Even a manual system where you need to use it like a generator for part of the day will add a lot to the cost.
@@jackthesolarguy it not as much a matter of roof size as it is prices on electricity over time when we look over longer time i have seen a 4x on 20 years here (2x the last 4 years) with the rising cost of power and lowering prices on solar. the 9-12 years might look different it took me about a year, but i also live in eu´s most expensive country when it comes to electricity but we are also 1 of the biggest producers of wind energy, so years of investing in green energy have not made anything cheaper
Question about the duck curve. That's what the house with solar uses and generates. But the individual will use up that solar energy generated at the home at their place of employment. I work in a shop environment with commercial air compressors, vacuum systems, lighting, air conditioning etc. Its not like when the person leaves the house they stop using electricity. It offsets WHERE they are using electricity. So if you do a graph of a persons energy usage during the day. i think it will be of a dome/mound shape. To follow what solar panels generate. The duck curve makes it look like the solar on people houses is overloading the grid with supply vs demand(from business and none solar powered homes). Hope that makes sense! Thanks for the videos!!
Your situation may be slightly different, however for most rooftop systems which have been designed to offset 100% of the homeowners annual usage, during those 4-6 afternoon hours which the solar panels are producing at peak, more than half of the energy generated will be pushed back onto the grid. Most homeowners already have a duck curve with their usage given that it is highest in the morning and afternoon hours when people are at home and not at work/school. For commercial projects it may look slightly different.
Jack does not seem to have understood the question. You are right that analysis needs to look at the whole system, and not house-by-house use. Of course exports to grid support out-of-home electricty usage. But it depends how much industrial use exists where you are. It is readily observed in NZ that middle of day demand is lower than morning and evening. It hasn't always been this way. If I look at yesterday, the "dip" in middle of the day is about 7.5%, so not very extreme.
@@enmodo Of course. But Jack's answer is talking about residential, and hence my comment. But equally, the duck curve has not always existed. We used to have peak demand around 2-3pm. The bigger question is whether - looking at all heat-power processes if that has a duck curve, or perhaps more work places utilise non-electrical heat sources and hence overall consumption of energy is higher in the middle the day. And that very much depend on what your econcmy is producing
It is not "That's what the house with solar uses and generates." as you have stated. He says, the Duck Curve is "Daily Net Energy Load on the Grid". It's "all usage" no matter whether people are at home, at work or at school. Recently states like California and Texas in summer time have generated 100% of their states daytime consumption with Clean Energy in the middle of the day. Also shown in his graph for California is the best "single day" out of each year listed. That is why CA and TX are also installing massive battery storage facilities for the past 2 years and into the future. It's absolutely game changing. It will take time before we have either enough storage capacity, and alternate clean sources to be able to start to bring down the tail and the head of the duck.
You forgot to talk about the change in Solar Technologies that are expected in the markets, like Perovskites Solar Cells that increases the efficiency of the panels.
Thanks for sharing your top 7 trends for 2025. I am considering going solar in Texas ( possibly anywhere between 13 to 16 kw using REC alpha pure series 460 and connecting 2 tesla powerwall 3). Can you please share your thoughts on whether Tesla Powerwall 3 is forward compatible with REC solar panles and also what would be the implications of the new administration's plan to cut down on IRA if we invest this year?
There are no compatibility issues between panels and batteries/inverters for the most part. You will just have to decide whether to use the Tesla Hybrid inverter or a seperate inverter system. The IRA is covered at the start of the video
@jackthesolarguy Thank you. I am planning to use Tesla hybrid inverter. Do you think Tesla might come up with bi directional battery support similar to that of Enphase sometime this year?
Imagine a US powered solely by solar PV. Per capita primary energy use 300GJ a year, 80% of that is fossil fuel energy. A single 250W panel in the US NE makes about 1GJ a year. So that means 300 panels per person and no means of averaging out over the long term variation. So 12 months a year for 12 units of energy, spring and fall will both give 3 units each but winter and summer will give 1 and 5 units resp. How do we move 2 excess summer units back to winter. We will probably have to triple production and throw away all excess, but then 3x the cost and landuse, but much smaller storage problem. Wikipedia Per Capita Energy Use, and LLNL Energy Flow Graph, 100XJ/330M is about 300GJ a year. Also see "Without The Hot Air" book on energy by David MacKay or the Bill gates version.
All that is needed to claim the 30% tax credit for a residential installation is to fill out a 5695 form which can be found on the IRS website of your preferred tax filing software. It’s a one page form which will take less than 5 minutes to fill out. What are you referencing as far as the difficulty is concerned?
@@jackthesolarguy Being a CPA (just about retired), the hardest part to fill out the 5695 form is to get the client to find their darn receipts. But please remember, the 30% of batteries is for storage in excess of 5Khw which is easy enough of a target. Even the really efficient furnaces or wood stoves qualify for the energy credits too. Never leave FREE money from the government on the table as I say.

Most homeowners already have a duck curve with their usage given that it is highest in the morning and afternoon hours when people are at home and not at work/school. For commercial projects it may look slightly different.
The duck curve of net demand on the grid is for all uses, commercial and industrial and consumer.
Jack does not seem to have understood the question. You are right that analysis needs to look at the whole system, and not house-by-house use. Of course exports to grid support out-of-home electricty usage. But it depends how much industrial use exists where you are. It is readily observed in NZ that middle of day demand is lower than morning and evening. It hasn't always been this way. If I look at yesterday, the "dip" in middle of the day is about 7.5%, so not very extreme.
@@enmodo Of course. But Jack's answer is talking about residential, and hence my comment. But equally, the duck curve has not always existed. We used to have peak demand around 2-3pm.
The bigger question is whether - looking at all heat-power processes if that has a duck curve, or perhaps more work places utilise non-electrical heat sources and hence overall consumption of energy is higher in the middle the day. And that very much depend on what your econcmy is producing
It is not "That's what the house with solar uses and generates." as you have stated. He says, the Duck Curve is "Daily Net Energy Load on the Grid". It's "all usage" no matter whether people are at home, at work or at school. Recently states like California and Texas in summer time have generated 100% of their states daytime consumption with Clean Energy in the middle of the day. Also shown in his graph for California is the best "single day" out of each year listed. That is why CA and TX are also installing massive battery storage facilities for the past 2 years and into the future. It's absolutely game changing. It will take time before we have either enough storage capacity, and alternate clean sources to be able to start to bring down the tail and the head of the duck.
You forgot to talk about the change in Solar Technologies that are expected in the markets, like Perovskites Solar Cells that increases the efficiency of the panels.
What do you recommend with another trend where solar panel providers are going bankrupt like Sunpower?
Jack can you do a reaction video for Tony Seba speaking in Saudi Arabia ? It would be interesting to see your thoughts.
I am not familiar with him

Thanks for sharing your top 7 trends for 2025. I am considering going solar in Texas ( possibly anywhere between 13 to 16 kw using REC alpha pure series 460 and connecting 2 tesla powerwall 3). Can you please share your thoughts on whether Tesla Powerwall 3 is forward compatible with REC solar panles and also what would be the implications of the new administration's plan to cut down on IRA if we invest this year?
There are no compatibility issues between panels and batteries/inverters for the most part. You will just have to decide whether to use the Tesla Hybrid inverter or a seperate inverter system. The IRA is covered at the start of the video
@jackthesolarguy Thank you. I am planning to use Tesla hybrid inverter. Do you think Tesla might come up with bi directional battery support similar to that of Enphase sometime this year?
@@jrjegon It is already released, but only compatible with the Cyber truck at the moment.
@jackthesolarguy Thanks
Who is currently providing made in America panels right now? You keep referencing that that not saying outright who’s doing it now!

Trump term will be a shit show regarding renewable energy. Trump motto "drill drill"
Imagine a US powered solely by solar PV. Per capita primary energy use 300GJ a year, 80% of that is fossil fuel energy. A single 250W panel in the US NE makes about 1GJ a year. So that means 300 panels per person and no means of averaging out over the long term variation. So 12 months a year for 12 units of energy, spring and fall will both give 3 units each but winter and summer will give 1 and 5 units resp. How do we move 2 excess summer units back to winter. We will probably have to triple production and throw away all excess, but then 3x the cost and landuse, but much smaller storage problem.
Wikipedia Per Capita Energy Use, and LLNL Energy Flow Graph, 100XJ/330M is about 300GJ a year. Also see "Without The Hot Air" book on energy by David MacKay or the Bill gates version.
Modern solar panels are at least 400W per normal size panel.
Hopefully 300watt ones not 100watt ones from China.
I don’t know why people are not given the option to charge their EV’s during the day, while they are at an office with solar power panels parking lot.
That is what should be happening, but most people charge their EV’s once they get home from work around 6pm (worst possible time)

I looked into it and the 30% solar credit was a joke. You would loose most of it in hiring an accountant to understand the illogical government forms.
All that is needed to claim the 30% tax credit for a residential installation is to fill out a 5695 form which can be found on the IRS website of your preferred tax filing software. It’s a one page form which will take less than 5 minutes to fill out. What are you referencing as far as the difficulty is concerned?
@ what I saw on the government website was a stack of forms.
Yea, it really is very easy.
@@jackthesolarguy Being a CPA (just about retired), the hardest part to fill out the 5695 form is to get the client to find their darn receipts. But please remember, the 30% of batteries is for storage in excess of 5Khw which is easy enough of a target. Even the really efficient furnaces or wood stoves qualify for the energy credits too. Never leave FREE money from the government on the table as I say.
Loose😂😂😂😂😂😂😂
