Heating water is one of the biggest pieces of a Hawai'i electric bill — and with year-round sun, solar hot water is one of the fastest-payback upgrades you can make. We install and service systems on Oahu and Maui.
Water heating quietly eats a big share of most Hawai'i electric bills. Because the islands get strong sun nearly every day of the year, a solar water heating system can cover the vast majority of your hot water for free — making it one of the fastest-payback solar upgrades a homeowner can make here.
A system is straightforward: roof-mounted collectors heat your water using the sun, an insulated tank stores it for whenever you need it, and a small electric backup only steps in on the occasional cloudy stretch. Pair it with state and federal tax credits and $0-down options, and many homeowners see the system pay for itself in just a few years.
It's one of the simplest ways to take a real bite out of your HECO or MECO bill — and it works beautifully alongside a PV system.
Because water heating is such a large slice of your bill, solar hot water typically pays for itself faster than almost any other solar upgrade in Hawai'i.
Hawai'i's steady sun means consistent savings every month — no seasonal slump like you'd see on the mainland.
Solar water heating generally qualifies for the 30% federal credit plus Hawai'i's state credit, shrinking your out-of-pocket cost.
