Self-Supply = PV + Battery Storage
The name of the residential solar game in Hawaii is Self-Supply. Self-Supply means only your home uses the electricity generated by your photovoltaic (PV) panels. Energy produced by your panels is stored in batteries until you use it. Self-Supply systems have a one-way connection to the power grid that allows electricity to be purchased from the utility; no electricity can be exported to the grid.
