15 cents a kilowatt is pretty low for most of California. California is one of the few power markets that make solar on the grid a viable option.
Pretty low? According to this link it’s average:

But even at let’s say 25 cents a kilowatt hour it still doesn’t make much sense to me. A 1000 watt light run 24 hours a day would cost about $200 a month to run. At $13k a month, that would be about 65 of those lights running all day for a month. 65 1000 watt light bulbs on even a 240 volt circuit would come to 271 amps a day. Unless they replaced the circuit breaker I just don’t see it. The max a circuit breaker can handle in a residential complex is 200 amps.
