I agree with the do it yourself for cost savings if you have the ability and I totally support that. There are a many rebates and tax credits that make solar more affordable at this time:

AB 920 requires utility companies to pay households or businesses for any extra electricity produced by the customer’s solar power system. Supporters said the bill would encourage customers, who previously had no incentive to use less electricity than was generated, to be more efficient.

SB 32 expands the feed-in tariff program for large-scale solar facilities from 1.5 megawatts to 3 megawatts, potentially pushing utilities to construct massive solar installations on unused spaces like parking lots and warehouse roofs.
