Cool stuff. You've already generated more than I have in a full year, but then you have more panels and will get more sun. I've not had issues with the panels getting dirty yet. We did have a little snow, but it slid off them. We've had a few days of blue skies and production is booming.
Being able to run a car off solar is a wonderful thing. We could possibly do that over the summer months.
Do you foresee less encouragement of people to fit solar in the next few years? That would be shortsighted.
