The only negative thing I feel about all of this is that we're doing now. Once the glaciers are farked, the snow is going and the mass die offs are started. Better late than never they say, but why the hell didn't we just invest in this in the 1990s?

Lobby from the other people selling energy: the not green type. They have the money, the lawyers, the ads, everything. Balcony solar power is only allowed now due to energy shortage.

I have 2kW of panels on my balcony and 4kWh of batteries. I'm happy with the setup. I expect it to pay for itself in just a few years. The only thing I wish it had is open APIs to control the inverter and the batteries, ideally over bluetooth, so that I'm not forced to use an app.

I use victron devices and a litime battery + an esp32 of your choice and some LLM magic to read and relay data from Bluetooth to web.

For both victron and litime plenty of examples exist, including home assistant integrations.

Solakon One has a quite decent API you can control without cloud being involved...

Earlier quoted context omitted.

Solar panels were expensive and not very efficient then.

Do you think more investment / subsidies weren't possible over the last few decades?

They were and Germany was actually going in that direction, but it took the manufacturing scale of China to create an incentive to introduce the hundreds of minor changes necessary to get costs down.
