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.

Residential is expensive anyway, larger installations are plenty viable. My town in a northern Michigan is installing solar to help stabilize the rates they offer (I pay about 11 cents per kWh).

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…

It's hard for people to really understand this because utilities and grid operators are using this is a headline justification for electric capital projects. In New York, they've deferred capital projects for decades and we're absorbing a massive distribution charge increase. I think my electric delivery portion of the bill is up 40%.

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…

Australia is lucky, we get hot summers and mild winters, which means our electricity demand is highest precisely when we get the most solar.

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.

My point is that scaling coordination issues exist for everything, including all sources of energy production.

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.

Also, power companies did not necessarily kill energy export incentives. Here in Massachusetts my meter “runs backward” when I export to the grid. This does not earn me money but it does earn me kWh credits, which means that if I am net negative for energy import in the summer and net positive for import in the winter, I can be net zero (or close to it) for the year.

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.

There 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…

No, you are reading the article wrong. It is indeed 60% of new electricity generation that is from solar, not capacity

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…

Generating your own power does not necessarily mean cutting ties with the grid. I think for most people in most places being off-grid would be a real challenge. I’m not sure how Australia does it but in my neck of the woods (northeast US) staying grid-tied is the norm.

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.

That appears to be true in places in the US that have time-of-use rates. Sadly where I live, there are no time-of-use rates for residential customers, otherwise I would absolutely do this.

Curiously, TFA doesn't raise the question of why demand surged, it spends its 8 microparagraphs only praising solar.

I'm going to go out on a limb and say it has some thing to do with those data centers and LLM stuff.
