Solar Water Heater Rebate

Summary

Hawaii Energy, a third-party administered public benefits fund, provides incentives for energy efficiency and conservation to customers of the Hawaiian Electric Company (HECO) and its subsidiaries, Maui Electric Company (MECO) and Hawaii Electric Light Company (HELCO). This incentive is available for installations on the islands of Oahu, Hawaii, Maui, Lanai and Molokai.

Residential utility customers in Hawaii, Honolulu, and Maui counties can choose between a direct upfront rebate of $1,250 or a $1,250 interest rate buydown. They cannot receive both. The upfront incentive is paid to the installer and deducted from the customer's final bill. The interest rate buydown is paid to participating lenders. The lender, in turn, will provide the customer with a 0% or low interest loan depending on the customer's credit and/or the financial institution. The commercial rebate for solar water heaters is $250 per ton de-rated output. 

Hawaii Energy provides a list of participating contractors that have agreed to comply with the programs' rigorous standards regarding equipment use and installation. A participating contractor will visit the home or business, analyze the building's hot water usage, and provide a bid for a complete installation, including the anticipated energy savings. Hawaii Energy will perform a comprehensive post-installation inspection to ensure the system was installed to meet the proper standards. Customers may also qualify for the Hawaii State Energy Tax Credit and the federal tax credit for solar water heaters.
