This is my parents' home in Aomori Prefecture at the far northern tip of Honshu, Japan. During daylight hours, the photovoltaic panels provide enough electricity to run the home and feed energy back into the grid, which does net metering. The wind turbine mounted on the pole to the right provides a few additional watts of power for the home. Water and house heat is provided primarily by solar water heaters and an on-demand propane heater. My dad has purchased additional PV panels since this photo was taken.
