@cjd You think India is less corrupt than the US?
The people who have deception and scamming as an integral part of their culture?
Are you serious?
@cjd The problem is scale and redundancy.
The math just isn't the same.
I don't know the math on batteries, but no one seems to be doing that.
I think the issue is discharge rates, and subsequent overheating, but I'll need to look into it more sometime.
I know a bit more about solar though.
For starters, cells lose efficiency with temperature, so on summer months you might want to have those panels well above the ground, or employ water cooling.
Panels are designed to work best at roughly 25°C and on hot days they can reach over 65°C, leading to a 10-25% drop in efficiency.
Transporting the power comes with losses, so you want a power plant near your major cities, but taking up lots of real-estate near a city is costly too, which is another consideration that private consumers don't have.
Finally, the redundancy.
You need to have turbines ready.
Which means warm at least (preheated), if not idling.
So you pay extra for the installation, but then you still have to keep the turbine on top of hiring more technicians to maintain the solar cells.
I think it's a hard sell for most power plants.
I draw, code, and make memes sometimes.
