Forgive my ignorance, what does one do during non-insolated hours? Do solar cells typically come with battery packs or does one just pull from the grid?
If the latter then the cost savings are a bit less impressive than stated.
Also can you put power back into the grid in San Francisco? Is that benefit included in the cost savings estimate?
