Start saving up to 40%

For families of four or more, installing a solar water heater can save you up to 40% on your electric bill (over $1,900) per year. With those savings, imagine what you could buy with that extra money: round trip outer island flights, 800 lbs. of rice, 850 malasadas or 270 pairs of slippers!

Affordability options

Solar water heating can be affordable with Hawaii Energy. Whether you are purchasing a brand new system or need to replace your current system, here are two options:

• Hot Water, Cool Rates: We can help you finance a new solar water heating system with a zero to low interest loan through one of our participating lenders. Apply to receive a $1,500 Hawaii Energy rebate (credit) to be used towards your first payment on a new loan.

This measure may qualify for valuable tax credits through the Inflation Reduction Act. Please check with your tax professional on applicability.
