Our electricity is sufficiently cheap that solar panels are quite marginal, plus we get bad hailstorms occasionally. I'll probably still pull the trigger eventually, but it won't be a particularly savvy decision.

When we were deciding on solar panels I did a quick NPV calculation and realized it was one of the easiest financial decisions ever.

Not quite the same with electric cars though.  That decision is more marginal, even with federal and state electric vehicle subsidies.

Your solar panels should pay for themselves in no time then, especially with whatever crazy subsidies I assume CA has.
