Solar Hot Water on the Big Island of Hawaii
As homeowners on the Big Island of Hawaii look for ways to cut energy costs and embrace sustainability, solar water heaters have become an increasingly popular investment. With Hawaii’s abundant sunshine and high utility rates, switching to a solar water heating system can offer significant savings while reducing reliance on fossil fuels. In this guide, we’ll explore the cost of solar water heaters, the benefits they provide, and why they are a smart choice for Big Island residents.
How Much Does a Solar Water Heater Cost on the Big Island?
The cost of installing a solar water heater in Hawaii varies depending on the system’s size, type, and installation requirements. On average, homeowners can expect to pay between $6,000 and $9,000 for a full installation. Fortunately, Hawaii offers several financial incentives that can help offset the initial expense:
Hawaii Energy Rebate – Eligible homeowners can receive a rebate of up to $1,000 for installing an approved solar water heating system.
Federal Tax Credit – The Federal Solar Investment Tax Credit (ITC) allows homeowners to deduct 30% of the cost of their solar water heater from their federal taxes.
State Tax Credit – Hawaii offers an additional 35% state tax credit, making solar water heaters even more affordable.
With these incentives, the actual out-of-pocket cost can be significantly lower, making solar water heating a cost-effective option for many Big Island homeowners.
Cost Savings and Expenses
Investing in a solar water heater can lead to substantial savings on energy bills. For a typical family of four in Hawaii, installing a solar water heater can save up to 40% on the electric bill, amounting to over $1,900 annually.
The average cost of installing a solar water heater in Hawaii is approximately $4,000. However, homeowners can benefit from financial incentives to offset this cost. The Hawaii Energy Tax Credit offers a 35% income tax credit on new installations of solar water heating systems, up to $2,250 per system.
Additionally, the federal government provides a 30% tax credit for solar water heater installations, further reducing the overall expense.
Considering these incentives, the payback period for a solar water heating system in Hawaii can be relatively short, making it a financially viable and environmentally friendly option for many homeowners.
By carefully weighing the pros and cons and consulting with local professionals, residents of the Big Island can make informed decisions about implementing solar water heating systems in their homes.

Increased Home Value – Homes equipped with energy-efficient systems like solar water heaters are more attractive to buyers, potentially increasing resale value.
Hawaii’s Solar Water Heater Mandate – Since 2010, Hawaii has required all newly constructed homes to install solar water heating systems, further emphasizing the state’s commitment to clean energy.

When selecting a solar water heating system, Big Island homeowners should consider:
Roof Space & Orientation – Ideally, panels should face south for maximum sun exposure.
