China Smashes Solar Installation Record In May (oilprice.com) 44
An anonymous reader quotes a report from OilPrice.com: China installed its highest solar power capacity for a single month in May, according to official data, which showed mind-boggling figures that the country installed more solar capacity in a month than any other nation did for the entire 2024. With 93 gigawatts (GW) of solar capacity installed in May, China smashed its own record of 71 GW in December 2024, per data from the National Energy Administration cited by Bloomberg.
China's solar capacity additions in May were rushed ahead of a new government policy -- effective June 1 -- to remove pricing protection for solar power projects. Under these protections, solar projects had all but guaranteed profits when they start operations. Another new rule, effective May 1, made connecting rooftop panels to the grid more difficult. These new policies are expected to moderate the growth in solar power additions this summer, analysts say. A separate report notes that China's cumulative installed solar capacity has surpassed 1 TW, according to the National Energy Administration (NEA). "By the end of May 2025, solar capacity had reached 1.08 TW (1,080 GW), up 56.9% year on year," reports pv magazine.
"NEA data show total power generation capacity stood at 3.61 TW at the end of May, an 18.8% increase from a year earlier."

The average solar PV capacity factor in the U.S. is 24.5%. 3.61 TW at 24.5% for one year is 7.7 PWh. Total electricity usage in China last year was 9.5 PWh.

Correct. Teslas Powerwall has generally addressed this at the personal consumer level. And most humans don’t work at night either, making addressing that demand a bit easier.

Adapt or die. Coal is dying. In those cities and countries, we must determine if it is corruption or capability holding back progress. And then address it.

I've recently started looking at my power consumption on a 15-minute graph, and it turns out that power usage isn't all that much less during the night. In fact, at times it is higher because all the lights are turned up. But even at night, there's the fridge and freezer, the house electronics, security cameras, etc.
Turns out the stuff I need for work - a notebook and an external screen - barely register.

Because it's FAR from free. I'm very pro-nuclear, but we need to be honest about the pros (MANY) and the cons (several) of nuclear energy. One of the biggest problems is waste storage - instead of stashing it in an abandoned mineshaft in the Nevada desert (we can thank ex-senator Harry Reid for that), we store it on site. This is an expensive problem. This can be remedied with legislation, but unfortunately the Legislative branch of our government has a very difficult time passing laws, except on culture wa

Sounds like copium to me. Nuclear fission has lost the PR war, the economic war, and the tech war, and now you're hoping you can bring it back from the dead by slagging the competition with baseless hyperbole. Well, good luck with that; but it sure looks like that race has already been called. I still have hope for nuclear fusion, FWIW.

And because we haven't built nukes in quite some time, you'll have to expect overhead for companies regaining the know-how and fixing blunders.

Every house should have solar panels. Forget the environmental impact of oil, look at all the screwed up things oil money funds. For that reason alone we need to switch to solar. Furthermore, if your house has solar .. that gives you more freedom. You're not subject to energy price fluctuations. And heck if you lost all your money you can still survive. I guess you'd need to figure out food I suppose (in theory can grow it indoors with solar energy), but maybe you can use the solar power to get on TikTok and get money for food.

Yes, but even if the energy they produce more than pays for themselves many homeowners lack the capital to install them or have other uses for that capital.

One is that there is a huge centralized energy industry with investors that make money building large generators and the infrastructure to deliver the power where it is used.

You just put high enough tariffs and if possible some extra taxes in the imported solar panels, and hand out that money with 0.5% interest to home owners, to buy solar panels.

Solar only works if you either have a huge roof or get a low energy heat pump for which you need a high level of insulation which may well cost six digits to achieve for existing houses.

I've installed a really small solar array and on sunny days I produce more electricity than I use. I'm sure it'll be a lot less in winter. BUT - I have a wood-burning heater which needs only a bit of electrical power for its control system. I'm pretty sure I can produce enough of that even in winter. So in theory, with the addition of a battery to cover the night, I could survive even if the power grid went down for an extended time.

There are stupid regulations in our neighborhood holding us back. I'd rather not pay for a battery pack, just the panels. It would cost us roughly half as much. But we also want to use our OWN power if the grid goes down, which it does often, but regulations forbid that: we must buy a battery pack to have that ability.
I realize a battery pack gives us off-hour power if the grid goes down, but since it's only a spare, we don't care that it would only work during the day. It would be enough to keep our food f

Re: (Score:2)
You can't really ignore the solar fraction, though, or the also-large wind fraction; even in 2023, the two made up about 43% of total capacity. Those two chunks are counted as nameplate capacities rather than typical output, and typical capacity factors are 15-25% for solar and 20-40% for wind. That means the actual generation is a lot less than 3.61 TW, almost certainly less than 3 TW, and possibly less than 2.5 TW. The US is a lot less affected by those factors (see, for example, https://www.eia.gov/en [eia.gov]
