Solar panels are cheap but batteries are very expensive.

Batteries are dirt cheap already and getting cheaper all the time. Pakistan would be buying them at the Chinese prices without a lot of tariffs or nonsense that might be misleading you into believing otherwise. Think a bandwidth of 50-80$ per kwh cost levels for the manufacturer with a margin on top in a market where there's over production and prices are still trending down and margins are probably under quite a bit…

They're cheap and getting cheaper. Your info is from 2021. Things change quickly in this industry.

if the same solar also had enough battery capacity, sure. But they do not, they still need to buy at out of solar peak and that just causes problems for both sides. I think grid should start moving into selling storage as a service. Just put a bunch of bulk storage at every transformer station and buy solar from consumers at solar peak, sell them back say 80% of it (or whatever margin is required to pay for it) off p…

EVs have giant batteries - they can be connected via their DC ports and charged/discharged via solar inverters - technically. The current spec for CCS and NACS doesn't allow for this (Chademo did, but they lost the 'format war'). Giant effing oversight on manufacturers' part if you ask me. Some people have managed to trick their cars into reverse charging via solar hybrid inverters and some custom hardware and it wor…

Balcony solar is even cheaper to build than utility-scale solar.

It's limited to 800W in Germany and 1200W in Utah. It isn't about to replace utility-scale generation anytime soon.

Unpopular opinion: this is so contentious because it’s more about control.

It's crazy to think that thanks to Starlink, EVs, renewables, a small-ish rural community could become almost independent.
