Hawaii Solar Rebates and Incentives

Hawaii Rebates and Incentives Summary

Hawaii

 

Hawaii is gaining a reputation in the solar industry as a litmus test for grid management as residents get a greater and greater percentage of their power from distributed renewable energy generation.

While Hawaii only ranks seventh in the country for installed solar capacity, utilities in the state started hitting their caps on integration agreements for rooftop solar installation in 2012. With nearly 10 percent of the population in most Hawaiian utility territories drawing power from the sun and feeding their excess onto the grid, Hawaii is the first to face the real grid integration issues that have had utilities in other states fearing for their futures.

Hawaii’s Public Utilities Commission rejected Hawaii Electric Companies’ long-range plan because it didn’t incorporate enough rooftop solar and didn’t solve for potential grid instability.

Because the state relies primarily on imported fossil fuels for electricity, rates are nearly triple what they are in the rest of the United States. As the price of solar installations have plummeted, Hawaiians have put solar on their properties at record rates.

As utilities stopped allowing grid connection, Hawaiians started to defect from the grid in favor of solar installations.

The state is still wrangling with its solar policies and the utilities will have to find a way forward that could lead the rest of the nation to a solution that will allow for more solar and clean energy.

With strong public and government support, there’s no indication that growing pains will stall solar growth in Hawaii. Some of the state’s incentives are on hold while utilities work out the logistics, but Hawaii still has an ambitious goal to get 40 percent of its power from renewable sources by 2030.

To reach that goal, the state offers incentives like tax credits, a feed-in tariff, an evolving net metering program, and low-interest loan programs, Hawaii is helping its residents make the transition to solar and its renewable cousins. The state also offers rebates for solar hot water systems.

Hawaii has offered this renewable energy state tax credit to residents and businesses since 1976, though the amounts and terms have changed over the years.

The tax credit is for the year the system was purchased and installed. It is only available to the purchaser of the system. So, if a developer builds 10 homes and pays for photovoltaics (PV) or solar water on each, the developer is considered the purchaser and eligible for the credits. But if the developer offers a system as an add-on, for which the buyer must pay extra, or if a homeowner contracts to have a system installed on their home, they are the beneficiary of the credit.

As of 2014, the income tax credits for solar photovoltaic systems are as follows:

• Single family homes are eligible for a tax credit of 35 percent of the actual cost of the solar system and installation up to $5,000.

• Multi-family residential properties, such as condominiums or apartment buildings, are eligible for a credit of 35 percent of the actual cost of the system and installation up to $350 per unit.

• Commercial property is also eligible for a credit of 35 percent up to $500,000.

Hawaii Feed-In-Tarrif

Rates for Tier 3 vary by technology

Required Documentation Varies by utility

Hawaii had one of the best feed-in tariff programs in the country when it started in 209. In fact, it was one of the only feed-in-tariffs. The idea of paying a premium to electric customers who produced their own clean power made sense in an island state that depends heavily on expensive imported fossil fuels for electricity generation.

However, the program has been at a stand still with no new enrollees since 2013. The state has the highest solar adoption rate of any in the country. With most utilities hitting their interconnection limits, the state is revisiting how it handles solar photovoltaic systems.

Hawaii Solar Hot Water Rebate

Program Type Rebate 
Technologies Solar Hot Water Heating
Amount $1,000 upfront for residential or $1,000 interest buy-down for residential hot water heating
Required Documentation Paperwork done by participating solar installer                                                                  
Official Web Site http://www.hawaiienergy.com/16/water-heating#solar-water-heating

 

The Solar Water Heater Rebate is offered through Hawaii Energy, a public benefit fund administered by a third-party. The incentive is a one-time $1,000 rebate for residents and companies that install a solar water heating system on their building. It is limited to the islands of Oahu, Hawaii, Maui, Lanai and Molokai. The rebate itself is applied by a participating contractor at time of sale. The program maintains a list of participating providers at its website.

The rebate was instituted in 1996 and has helped more than 50,000 solar hot water systems get installed on the Hawaiian islands of Oahu, Maui, Lanai and Molokai. The program was managed by the utilities, but in July 2009, it was transferred to Hawaii Energy.

With these rebates and other tax credits and incentives, a solar hot water heating system can cost as little as $2,000.

Homeowners can choose to participate in the interest rate buy-down program instead of receiving the rebate. Through this program, Hawaii Energy pays $1,000 to participating financial institutions, reducing the cost of financing to the homeowner.
