Hawaii Energy Announces Increased Rebate For Residential Solar Water Heating Systems

Honolulu, Hawai‘i – Hawaiʻi Energy, the state’s Public Benefits Fund administrator that focuses on energy-efficiency education and clean-energy initiatives, is now offering an increased rebate for residential solar water heating systems. From now until June 24, 2024, Hawaiʻi residents who install a new solar water heating system can receive a $1,500 rebate, an increase of $500.

“A solar water heater alone can reduce monthly electricity bills by up to 40%,” said Caroline Carl, executive director at Hawaiʻi Energy. “To date, Hawai‘i Energy has helped more than 24,000 households afford solar water heating systems and reduce their energy costs for years to come. With Hawai‘i’s electricity rates being the highest in the nation, this is one of the biggest ways to bring down an electric bill, and we highly encourage residents to take advantage of this limited-time offer.”

Hawaiʻi Energy’s Residential Rebate Program makes it easier for residents to invest in energy-efficient equipment and installations. In addition to the solar water heating system rebate, a $200 solar water heater tune-up rebate is also available, which is recommended every five years.

Some customers may qualify for a federal tax credit of 30% and a state tax credit of 35% off the costs of the solar water heating system and installation. Hawaiʻi Energy encourages residents to contact their tax professional for details on how to apply.

Hawaiʻi Energy rebates are available to residential electric utility ratepayers on Hawaiʻi Island, Lāna‘i, Maui, Moloka‘i and O‘ahu only. They are available on a first-come, first-served basis and are subject to availability of funds. Kaua‘i residents are serviced by a utility cooperative and therefore not eligible for Hawai‘i Energy rebates.
