Rebates and Incentives

Hawaii is at the forefront of the nationwide movement to generate power from renewable sources of energy. In fact, under the recent Hawaii Global Warming Solutions Act, the state intends to reduce greenhouse gas emissions to 1990 levels by 2020. To achieve this goal, Hawaii offers substantial incentives to business owners who wish to invest in renewable energy technologies. In combination, these incentives enable businesses to receive approximately 65% off the price of a solar electric or solar thermal system and pay back their initial investment fast—in some cases within two years!
