Going Solar

Financing Your System

There are many different options available to help finance your solar system. Talk to your financial institutions about financing options. Many solar companies will help customers find financing options, as well. Talk to your accountant to understand which option provides the best financial benefit for you.


Tax Credits

Get the latest information on the new temporary administrative rules regarding State tax credits. Check with your tax consultant to determine if you qualify to receive federal or state tax credits.

  • A 30% federal tax credit is available to eligible solar energy (including solar water heating and solar PV systems) and other renewable energy systems placed into service before December 31, 2016. Visit the Database of State Incentives for Renewables & Efficiency, www.dsireusa.org, for detailed information.
  • The Hawaii state tax credit for PV system installations is 35%, up to $5,000 per system, on a single family residential property. Solar water heater installations on single family homes also qualify for a 35% tax credit, up to $2,250. Both non-refundable and refundable options are available. Visit the Hawaii Department of Taxation site, to download the N-342 form and instructions to see if you qualify for a state renewable energy tax credit.
  • Hawaii Energy currently offers a $1,000 rebate on solar water heater systems. Visit https://hawaiienergy.com/ for the latest information.

Finance-to-Own

Many banks in Hawaii, as well as contractors, have programs that can help you finance your solar system, either a solar water heating system or a solar electric (PV) system. Finance-to-own agreements typically come in the form of equity-based loans or unsecured loans. Equity-based loans may take longer to obtain approval but allow the homeowner a larger amount of potential financing. Equity-based loans offer amounts up to the amount of equity available on the property. Unsecured loans are typically based on the credit rating of the homeowner. Unsecured loans usually have lower loan availabilities (up to $50,000), but offer the homeowner great terms such as 0% interest and $0 payments for a specified period. The system cost usually determines which financing option would best suit a homeowner's situation.


Lease

Leasing is a another way to finance a solar PV system for homeowners or businesses looking for a low-cost solution to their electric bills. Leasing arrangements are often confused with Power Purchase Agreements (PPA), but there are many differences between the two. Leased PV systems can be sized to fully offset a homeowner's current electric bill and generally have generation guarantees. If the system does not perform as specified, the lessor will cover the agreed upon costs. In general, lease agreements tend to have agreed upon monthly payments. The homeowner is still required to pay the utility any interconnection fee and for any energy used that is not generated by the leased PV system. Depending on the actual lease agreement terms, appropriate sizing of the PV system may be important so that the lessee does not end up paying for more electricity than their actual electricity load.


PPA

Power Purchase Agreements (PPAs) are where the PV system is owned by a financing party such as a PV development company, and the homeowner signs a contract with the PV financier to buy the PV electricity at an agreed-upon price per kilowatt-hour. Often the price may escalate after a set number of years. PPAs may be an attractive option for homeowners who don't have the cash to buy the PV system themselves and who don't want to worry about ongoing maintenance of the PV system, since this is the responsibility of the PV financier. The homeowner pays for all of the electricity that is produced by the PV system. As such, it is important that the PV system not be sized greater than needed to meet the customer's needs.
