The grid needs to be decentralized. More solar on rooftops and neighborhood backup batteries. This would help level out demand.
In other parts of the world this is fairly affordable. In the USA its astronomically higher. I speak from firsthand experience. When installed its wonderful, but is really pricey up-front, and just a small fraction of Americans are both homeowners, and can afford to buy these systems. The Inflation Reduction Act brings the price down from 10x the cost of other nations to just 7x the cost. Its an improvement, but not enough to make these systems widely available to all household budgets.
Rooftop solar panels should be offered for free by either the local government or the power company at this point.
To be fair this is just if you pay professionals to do it. They charge astronomically out the ass for labor for no reason. The actual cost of the equipment is surprisingly little if you buy it yourself, and installing it is very straightforward and easy you do not need to be particularly intelligent or skilled. I've done about five different systems at this point, two on RVs and three on houses. One of the houses and one of the RVs was my own and the rest are friends that I have helped set it up.
For example with a goal of about 20k spent This bundle gets you 12Kw of inverter output and 30Kwh of batteries for 11k. Then just grab two Of these solar panel pallets for 28Kw of panels. Or Alternatively go smaller with just one pallet and save a bit. Then ofc you will get the 30% federal tax credit on top of everything.
Ask any installer for a similar sized system and it's almost certainly going to be 80k+ at minimum. The only part you may definitely want a professional for is if you plan on roof mounting them, have a roofer come help install the framing so you can ensure no leaks. But for ground mount (or if you are familiar with roofing) even that's not needed.
The actual electrical works is very straight forward. Everything is very clearly labeled, the documentation is very explicit about what goes where. On the solar panel side you're literally working with DC so you're literally only dealing with positive and negative. Even on the AC coupling side when you're talking about an off-grid inverter you're not back feeding into the grid so it's very straightforward. Your house grid goes into the input, and your output on the inverter goes to your panel.
The only stuff to watch out for in the NEC is rules about where your secondary panel for the solar output can be placed, has to be a certain distance from the ground, has to have a certain amount of clearance around it on all sides, has to be accessible, stuff like that but it's all fairly easy to just look up thankfully
Not sure what the price is elsewhere, but I got 6.4 kW solar panels and a 10kW battery backup last year, and the cost was $33k USD. This was in U.S. Midwest (Colorado) and with a local (not National) Solar provider.
I paid cash to avoid the 6% rate loan and additional fees, and I received a $9k tax credit for it this year, bringing the total cost down to $24k. I think this is an expense beyond many Americans, especially since this system could take over a decade to pay for itself, if it does at all.
No point here, just figured I’d point it out so people are aware of the cost. And bear in mind, this is a small system, in a small (just over 1k sq/ft) home.
