This is brilliant. In Germany, it's popular to buy €200 solar panel / inverter combos that plug into a nearby power outlet, feeding the power back into the grid, running their power meter backwards. "Installation" just takes a minute. Folks in apartments simply hang them from their balcony “like wet laundry.” Over 500,000 have been sold. With power at €0.25/kWh, the payback time is about 27 months—after that, it's just free electricity. https://www.nytimes.com/2024/07/29/business/germany-solar-panels-climate-change.html?unlocked_article_code=1._E0.zL83.1FCeoxOrFDBY&smid=url-share
Germans Combat Climate Change With D.I.Y. Solar Panels

Plug-and-play solar panels are popping up in yards and on balcony railings across Germany, driven by bargain prices and looser regulations.

@waldoj what do you mean, power at 0.25 EUR/kWh :) We still pay 37¢
@ctietze I'm just repeating what the article says. ("Electricity prices in Germany jumped after Russia invaded Ukraine, and have now settled at around 25 euro cents per kilowatt-hour. But they remain among the highest in Europe.") I've got no special knowledge of your power rates. :)

@waldoj I just read the article, and I'm even sadder to hear that 25¢ was considered to be expensive

Good thing is our solar panels will payback even sooner 🥲
