Politicians are getting in the way. While they officially want to reduce pollution they also do not want to eat too much in the profits of their corporate sponsors.
For example in Silicon Valley you need to get permission from PG&E (yes the Erin Brockovich foes) before you can be permitted to install panels. They can refuse if your capacity will be too high. Locally we are not allowed to cover the entire roof, as the firemen need room to walk on the roof. I get that one, safety first.
I'm considering putting panels on my south facing walls and get batteries. After that I might be able to curt the cord from the grid since they want to charge $25 to $50 per month just for the privilege to be connected to the grid. Knowing CA lawmakers they might want to pass a law to make it illegal to be off grid as PG&E profits would take a hit.
Again I'm talking profits, I'm charged $0.41 to $0.51 per kWh, plus a monthly minimum fee.
Going off grid would be a good way to say FU to them and save over $1k/y at current rates.
A friend of mine with no solar can have monthly electrical at $1k for a family of 5, insane.
Yes go solar, if not to save the planet, do it for selfish reasons: save your wallet in the long term.
