I had planned to install solar panels some day, but now I'm thinking solar shingles. Our current home has a heat pump, and I appreciate not ordering fuel every winter. (I can remember tossing burning pieces of toilet paper into the furnace before we got the new furnace at the old house. The old house was bulldozed a couple years ago, btw, after we sold it.) Wouldn't it be great not to have a big electric bill!
