I've thought about installing solar panels on my roof for years. But when I factor in installation costs, it never makes sense because the local energy rates are pretty reasonable... Also, I live in Southeast, a place with plenty of sun but nowhere near the Southwest. Solar panel prices fell hugely in the past years. Is there anything that could significantly reduce installation costs?
PV is wildly expensive in the US. Apparently you even need a permit from the grid operator for it. Here in NL they come to your house a week after you call and your panels are up and connected in 4 hours or so.
US electricity demand surged in 2025 – solar handled 61% of it

The issue is that works perfectly well when solar is a small % of the grid, but when that number grows, then you need grid scale solutions and coordination for things to continue working well. And that requires both technical skill and political will.
This isn’t remotely true. Solar / wind / nuclear / coal / gas / any electrical source including from neighboring grids can be inbound or outbound from your grid using, the grid. There are capacitors and transformers, relays and transmission lines. Any energy source can provide power. Solar used to give money back to its owners by selling power back to the grid but they killed that initiative quickly and will just use…

You are not wrong. The Australian grid shows that when solar is the dominant part of the grid, it can still work pretty well. But you need to plan for when the sun is not shining and adapt to the notion that base load translates as "expensive power that you can't turn off when you need to" rather than "essential power that is always there when needed". The notion of having more than that when a lot of renewables are…
That's why something like 30% of Australian houses have solar.
That said, grid prices spiked recently. Both a combination of subsidies expiring, and fewer people buying grid power (because of solar) causing fixed costs to be shouldered by fewer people.
It should be pointed out that while electricity prices went up on paper, a lot of people aren't paying those higher prices because they are on solar!

So your implication that other sources of energy currently do not need scaling coordination somehow? I fail to see how that is true, maybe you can provide some insights?
It's easier to coordinate N electricity suppliers when N is small.
Singling out solar and continuing to not prioritize it will inevitably lead to ongoing grid issues. Whereas this has been mostly solved for other sources, due to lobbying and legacy. Thus my confusion about the OPs half-baked point.

In MA and a few other states, polluters are also required to buy “renewable energy credits.” Since I have a solar array I can sell my RECs whether I export energy or not. It’s my first year with a solar array, so I’m not sure how much to expect, but neighbors tell me that they earn between $500-$1000 a year.

Re: US electricity demand surged in 2025 – solar handled 61% of it
#57There should be a minimum level of expertise or commitment to the truth so that publication who certainly think of themselves as major league or factual don't publish blatantly false statements like this. Yes, demand rose, and solar panels were installed whose capacity was about 60% of the new demand, but to say solar handled 60% of new capacity is blatantly false. As someone who owns solar panels, I'm painfully awar…

Solar is highly distributed. At the most basic level with a solar & battery system the production and consumption and CONTROL are all yours. You own it and it's literally on your property. Refinements on ways to sell it to neighbours / recharge various EV's / use it for new purposes are all up to you. There are lots of analogies to self hosting or concepts around owning and controlling your own data, when it's owned…
Cost. Useful life. I thought about an off grid system. Batteries are expensive. Also, unless you live in a dry place in the equator, You'll need to account for things like winter, long rainy spells, so either you add more batteries to account for multiple days (weeks? months?) of low generation, or you'll need a diesel/gas generator, or have a hybrid system instead, which basically means you're using the utilities ga…
I have a relatively big battery (12kWh) which is enough to see me through the evening during the summer months. We do not get quite enough sunshine where I live to be off-grid during the winter, but I can use the battery to hedge against grid outages which are common here in the winter due to storms (eg heavy ice taking down power lines).

Weirdly in the UK it seems to be best to charge battery overnight from the grid and sell back during the day alongside any solar generated.
