Solar power from 18 cents/kwh down to 9 over 15 years

In sunny states like California, solar power from Solar City is at an unsubsidized 18 cents per kwh. However, is subsidized which brings it down to 12-15 cents per kwh for many locations. This is cheaper than the lowest tier of PG and E electricity at 15.5 cents. There are four pricing tiers and they increase and usage increases and go up to about 25 cents per kwh. In 15 years, Solar Cities scaling and technology plans could bring the unsubsidized price of home solar electricity down to about 9 cents per kwh. This would be lower than the average price of US electricity at 12 cents per kwh. Elon Musk also plans to provide batteries for power storage so that the solar power does not burn off as heat at the feeder stations on the one way power grid.
