Make no mistake, this is happening all over the globe with enormous success.

Australians now get free power for three hours a day. India, Pakistan and many other developing countries are deploying solar and batteries insanely fast because it’s so cheap direct from China.

China themselves add more solar capacity in a few months than the entire US grid.

There really is only one country with prohibitively expensive solar and batteries thanks to tariffs. Fingers crossed that will change soon.

Solar is also unique in that it is both affordable and practical to deploy locally.

Part of the difficulty in estimating growth is that a significant chunk of installed supply is not a "power station" that is easily counted and measured.

Residential solar is a few kw here, a few there. But it adds up quickly to mw and gw.

And yes, this results in a larger variable demand on the grid. Which makes planning harder. But it's cheap enough for any established business with a roof to install. It's cheap enough for residential. And from decision to power flowing can be measured in months not years.

What do panels cost in the US? I can order a 500W panel from amazon.de for a little under 100€. It looks like amazon.com only has panels for $300+. Is Amazon just very expensive?
