In Germany, 405 Watt panels new can be had for 65 euros. The law allows up to 800W to be connected to homes with relatively little bureaucracy, as a balcony solar power plant which renters can install without modifying the building. This seems to have pushed the price down, so there are many 800W kits including panels, an inverter and cables available for under 400 euros.

Mind sharing a link to buy one? Not in Germany but am in Portugal looking to buy

Sure thing, here is the solar panel: https://shop.green-cluster.de/products/405-watt-full-black-p... and here is the kit: https://www.netto-online.de/balkonkraftwerk-830-w-600-w-phot...

There are always lots of new deals, if you search for "photovoltaik" on mydealz.de you can find the latest offers in Germany

Nobody said "infinite". The upper asymptote of an S-curve is often called its "carrying capacity". We expect an inflection point about halfway toward this point. What do you think the maximum capacity of global solar energy is? The total amount of solar energy hitting Earth is about 4.4 * 10^16 watts -- 44,000 Terawatts. If we covered 1% of the Earth in solar panels at a meager 10% efficiency, that's 44 Terawatts --…

> 44,000 TW Check your arithmetic; it's considerably more than that.

There's a considerable difference between the amount that hits the atmosphere and the amount that hits the surface of the Earth. My number includes average cloud cover. It's this order of magnitude, and a higher number only strengthens my point.
