WHY USE SOLAR WATER HEATERS?
Do you know how much electricity your home uses for heating water?
Few people realize the energy required for hot water is about 30-40% for the average family’s energy consumption. With the amount of water heating needed for laundry, dishes, and showers, installing a solar water heating system can eliminate water heating costs for your home. We offer fast and efficient solar water system installations in Hilo and throughout the Big Island - no matter the size of your home, we'll ensure the work is done perfectly:
- Solar water systems
- Solar pool heating
HOW DO SOLAR WATER HEATERS WORK?
There are two major components to a solar hot water system. The first is the solar collector. The collector is usually installed on a roof facing the sun. Running through the collectors are copper tubing, filled with water that during the day absorb energy from the sun.
HOT WATER TANK
The second main element is the water tank which gathers and stores the hot water that flows in from the solar hot water panels.
The water in the solar collectors, heated from the sun, flows through piping and circulates into the tank, which ends up heating the water already collected from before.
READY TO GO
Hot water is now available which can be piped throughout the house for use in showers, sinks and appliances.
The heating system is backed-up by electrical or gas so there will always be hot water, even on cloudy days.
The great thing about living in Hawaii is our year round sunshine which means the back up systems are rarely used.
Currently, the federal government provides a 30% tax credit on photovoltaic and hot water systems. The state of Hawaii gives a 35% tax credit. Combined, these incentives can take care of roughly two-thirds the cost of the system.
Drainpipe Plumbing & Solar will guide you step by step on how to capitalize on these generous (and limited-time) programs.
In addition to Hawaii Energy’s rebate, you may be eligible to receive additional federal and state tax credits. Tax credits often reduce the amount of tax you owe dollar-for-dollar. State and federal tax credits are subject to change, as such, please consult your tax professional for further information.
Sample Cost Savings
To make it easy for you, we’ve provided you with the examples below, which show how Hawaii Energy’s solar water heating rebates, combined with federal and state tax credits, can substantially reduce the cost.
*$6,600 is the average system cost for existing home retrofits. Your cost may vary as different household needs require different sizes of solar water heating systems. Contractor prices may also vary. **Hawaii Revised Statute § 235-12.5 (b)(1)(A) caps the credit at $2,250 per system for single-family residential properties.
