After Hawaii regulators approved two new solar tariffs last month, solar customers in the state must now decide whether to buy, lease or pass on battery storage.
The two new tariffs are:
Smart Export, under which owners of solar-plus-storage systems will be able to maximize their use of stored solar to offset their nighttime consumption of electricity priced at Hawaii’s high retail rate. They will also earn some below-retail compensation for generation sent to the HECO grid outside peak solar generation hours.
Customer Grid Supply-plus (CGS+), under which owners of solar-only systems will earn modest compensation for any excess generation they send to the grid, whenever the sun is shining. Solar-plus-storage system owners will be able to choose how much electricity to send to the grid and how much to store to offset the retail rate at night.
