I bought a house about two years ago, and was in the process of restoring/renovating it when the Deepwater Horizon disaster happened. And I decided then to try to find ways to use my house to reduce my petroleum intake. I did all the usual stuff--heavy insulation, tankless water heaters, high-efficiency appliances and so on. But I also put solar panels on my roof--enough to generate considerably more than my family uses--and resolved to get a PiP as soon as it became available. Looks like I'll finally be getting the car in the next week, and am excited to start driving on my own home-generated power. I'm curious, are others in this forum charging off of solar? If so, any surprises or discoveries of interest?
