FAQs
How do I know if solar is right for my business?
The best way is to contact one of our representatives for a free, no-obligation site evaluation. You may also estimate the size, cost, and savings of a new system using a solar estimator. Solar technology has achieved a point in its development where almost any business has enough roof or ground space to generate sufficient electrical power to meet its needs.
How long will it take to pay for itself?
That depends on your method of financing and the size of your current utility bill. With the recent extension of the 30% federal Investment Tax Credit, solar power makes great sense for many businesses throughout the United States. In Hawaii, solar power is an even better investment. The State of Hawaii offers an incredible 35% state tax credit on all investments in solar power and solar thermal systems. In many cases, that means that businesses can receive 65% off the purchase price of a solar system and pay back their initial investments in only two years.
How long do solar electric systems last?
Because solar electric systems are made from high-impact tempered glass, have no moving parts, and require very little maintenance, they can operate reliably for 40-50 years—paying back the initial investment many times over! Hawaiian Energy uses only the highest-quality, state-of-the-art equipment on all our jobs.
Do your solar systems come with a warranty?
Yes. In the event that something ever does go wrong, all of our photovoltaic panels come with a 25-year manufacturer’s warranty. In addition, Hawaiian Energy covers all other parts of the system—including roof mounts, conduit, and every last nut and bolt—for 10 years.
Do I have to pay for the system up front?
That depends on your method of financing. For more information about financing options, please visit our Financing page.
How does it work?
There are five basic components:
- Solar Modules convert sunlight to electrical power. Typically, Hawaiian Energy professionals mount them in a steel frame attached to the roof of a commercial property or ground-mount them on a piece of land close to the site.
- The Inverter (or power converter) converts the direct current (DC) produced by the solar modules to alternating current (AC), the same type of electrical power supplied to homes and businesses from the utility grid.
- Power travels from the inverter to the breaker box, or electrical service panel, where it is then distributed throughout the home or business for use.
- When the solar electric system produces more power than you are currently using (for instance over the weekend at a business), the excess electrical power will flow into the electrical power grid of your local energy company through a special bi-directional utility meter, effectively causing the meter to run backwards and generating a credit with the utility company that will offset future usage. This arrangement is known as net metering.
- The utility grid is the state and national infrastructure that links homes and businesses to electricity-generating assets. The grid automatically provides electricity when business demand exceeds solar production.
