I've been using my solar system for some months now, but I haven't been approved to sell power back to the utility. Today I was approved to grid-tie the system. The first such installation for West Oregon Electric Co-op (WOEC). On this sunny afternoon my meter immediately started running backward, generating 1 kilowatt. I'll never make money at the current rates or number of panels, but it will offset some use, and gives me battery backup for my refrigerator and water purifier.

One more experimental feature of the house is to take an ordinary fridge, but put it inside an insulated box that is directly connected to the outside. For this purpose I intentionally located the fridge on the north wall.
The two white boxes are Panasonic passive air vents. I eventually discarded the covers to get 1/2" addtional depth.
The inlet and outlet covers on the exterior wall.
The fridge in place needing a seal and trim around it. A foot off the floor is a nice height for the fridge compartment, but the freezer is up there.
