I wonder if they are mandating grid tie also. My system is just under 1.0 kW (off grid) and, with a bank of several batteries, is just enough to run the primary electronics in the house and somewhat marginal in the winter.
How about adding a woodchip gasifier generator? Got chips?
That's probably the purpose. The only result of solar is to force other ratepayers (in other California cities) to pay retail prices for unreliable power with subsidies and profits going to the solar companies. It is a scam from top to bottom. Here in Virginia my power company can buy reliable power 24x7 for about 4 cents a kWh or they can be forced to buy solar power from an unreliable provider for full retail price. Obviously they are choosing the former as much as possible but can't say so publicly.
