German roof-top solar electricity may cost today as little as 120 euros per MWh and there is a lot more sunshine in Spain.

First Solar has not yet achieved grid parity. It is right now claiming that it can sell electricity with subsidies at 58 dollar price point, but this is not yet realized and it is not that particularly cheap. Centralized solar plant needs also expensive reserve generation capacity for winter, rainy days and night time production. E.g. in Germany average market price of electricity was €40 / $50 per MWh.

People often confuse retail prices and generation costs. Because transmission costs are quite high, it is better to go with decentralized roof-top solar production.
