HECO's Rooftop Solar Programs

  • Customer Grid Supply Plus: Customers who take advantage of the grid supply program will send any extra energy produced by their solar PV system to Hawaiian Electric in return for energy credits.
  • Customer Self Supply: Customers utilizing the self supply program can connect their rooftop PV panels to personal solar battery systems, such as the Tesla Powerwall II and LG Chem. Instead of being exported to HECO's grid, their excess energy can be stored for times when needed most, when solar power is not readily available; at night when returning home from work or in times of natural disaster.
  • Smart-Export: Customers who opt to apply under the smart-export program a solar storage system alongside their PV system that charges and receives credit from HECO's grid during designated hours of the day.
