PS: You also wouldn't believe how cheap the power is. California's prices are high compared to most of the US, but it's still only about €0.15 per KWh.
I don't know where you live, but I pay around 38 cents/KWh. Depending on your rate, that can go up to 53 cents/KWh during peak times.
16x is supposed to be the average. I live in upstate New York where I pay about 8c/kwh and a fixed $15/mo connection charge. We have day/night rates available but they're not very different for retail customers. I get a slight discount due to credits from remote net metering at a nearby solar farm.
