Hawaii: Commercial Solar Financing + Government Incentives 0

Many solar projects in Hawaii often face delays due to challenges in securing adequate financing. Fortunately, there are now more commercial solar financing options available for Engineering, Procurement, and Construction (EPC) firms and organizations in Hawaii. Whether you’re dealing with projects that are on hold or planning your next steps, we’ll provide an overview of the various financing options you can choose from.

We’ll explore all the key options, from both private and public sources, including solar Power Purchase Agreements (PPAs), solar leases, and Commercial Property Assessed Clean Energy (C-PACE) financing. We’ll also cover the specific government incentives available in Hawaii that can help turn your stalled solar projects into successful, energy-producing assets, advancing the state’s renewable energy goals.

Commercial Solar Financing Options in Hawaii

Solar Power Purchase Agreement (PPA) 

A Solar Power Purchase Agreement is a financial arrangement where a third-party developer installs, owns, and maintains a solar energy system on a commercial property, and the property owner buys the power generated at a predetermined, often reduced rate. This setup allows businesses to benefit from solar energy with no upfront capital expenditure and minimal risk.

Types of C&I Projects a Solar PPA Is Good For 

Ideal for large-scale projects such as manufacturing plants, resorts, or large office complexes in Hawaii, a Solar PPA allows organizations to avoid upfront costs while benefiting from lower energy rates. This is particularly attractive for businesses looking to mitigate financial risks associated with solar investments.

Solar Lease 

Similar to renting a property, a solar lease allows businesses to use a solar energy system installed by a third-party provider for a fixed monthly payment. This payment remains consistent regardless of how much power the system produces, and all maintenance is the responsibility of the provider, not the business.

Types of C&I Projects a Solar Lease Is Good For 

Solar leases are well-suited for medium-sized commercial properties, such as retail stores, small manufacturing units, or multi-tenant buildings. These businesses can benefit from solar energy without the need to invest capital in purchasing systems, while also avoiding maintenance responsibilities.

Solar Loan 

A solar loan is a traditional financing option where a business borrows money specifically to pay for the purchase and installation of a solar energy system. The business owns the system outright and benefits from all tax credits and incentives. Loans are paid back over time, typically with interest.

Types of C&I Projects a Solar Loan Is Good For 

Solar loans are perfect for businesses that prefer ownership to take advantage of the tax benefits, such as the Investment Tax Credit (ITC). They are ideal for commercial entities with good credit facilities and include operations such as corporate offices, hotels, or hospitals that plan to use the property over a long period.

Commercial Property Assessed Clean Energy (C-PACE) 

C-PACE is a unique financing tool that allows commercial property owners to finance qualifying energy efficiency and clean energy improvements through a voluntary property tax assessment. The financing is provided by the state or local governments and repaid over a long-term schedule, typically 10-20 years, which often aligns with the useful life of the installed system.

Types of C&I Projects C-PACE Is Good For 

C-PACE financing works best for commercial properties undergoing significant renovation or retrofitting projects that include sustainability upgrades. This can include shopping malls, older office buildings, or hospitality venues looking to enhance energy efficiency and increase property values through sustainable improvements.

Energy Service Agreements (ESA) 

In an energy service agreement, a service provider installs and maintains an energy system on a property at no upfront cost to the property owner. Instead, the property owner pays for the energy used at a rate typically lower than the local utility. This agreement can often include performance guarantees where the payment is linked to the amount of energy saved compared to a predetermined baseline.

Types of C&I Projects an ESA Is Good For 

ESAs are a great option for energy-intensive businesses like data centers, large supermarkets, or industrial facilities that want to reduce energy costs without upfront expenditure or ongoing maintenance hassles. These agreements provide a way to stabilize energy expenses while focusing on core business operations.

Hawaii Incentives and Federal Solar Tax Credits

What Is the Commercial Solar Tax Credit in Hawaii? (Renewable Energy Technologies Income Tax Credit

Renewable Energy Technologies Income Tax Credit (RETITC) allows businesses to claim up to 35% of the total installation costs for solar energy systems and up to 20% for wind energy systems, with a maximum tax reduction of $5,000. By taking advantage of this incentive, businesses not only lower their initial investment but also benefit from ongoing savings on energy expenses and contribute to Hawaii’s sustainability goals.

Example of How Much a Business Can Save Using RETITC

Let’s consider a hypothetical example of a business in Hawaii that installs a solar system costing $50,000. By leveraging the Renewable Energy Technologies Income Tax Credit (RETITC), the business can significantly reduce its net costs.

The RETITC allows for a credit of up to 35% of the total installation cost for solar PV systems. Here’s how it would work:

  1. Total Cost of the Solar System: $50,000
  2. RETITC Percentage: 35%
  3. RETITC Amount: 35% of $50,000 = $17,500

The business can claim a tax credit of $17,500 against its state income taxes for the year in which the system is installed. This reduces the effective cost of the solar installation from $50,000 to $32,500 ($50,000 – $17,500).

Federal Solar Tax Credit

Organizations such as businesses and non-profits that own solar installations can take advantage of two federal tax credits for solar energy.

  1. Investment Tax Credit (ITC): This credit allows for a reduction in federal income tax liability equivalent to a percentage of the solar system’s installation cost within the tax year. For systems installed from 2022 onward, and whose construction begins before 2033, the ITC provides a 30% credit.
  2. Production Tax Credit (PTC): This credit offers a per kilowatt-hour (kWh) tax credit for electricity generated by solar and other eligible technologies during the first decade of the system’s operation. It helps reduce federal income tax liability and is annually adjusted for inflation. Solar systems installed from 2022 onward, starting construction before 2033, can qualify for a PTC of 2.75 cents per kWh if they meet specific labor requirements set by the Treasury Department or if the system is under 1 megawatt (MW) in capacity.

Project owners should be aware that they cannot simultaneously claim both the ITC and PTC for the same property. However, they can apply different credits to co-located systems, such as solar and energy storage, based on specific criteria outlined by the Internal Revenue Service (IRS) guidelines.

Example of Savings Using Investment Tax Credit (ITC)

Let’s consider a hypothetical example to illustrate the savings a business in Hawaii can achieve by claiming just the Investment Tax Credit (ITC).

Assume a business installs a solar system costing $100,000.

  1. Initial Cost of Solar PV System: $100,000
  2. ITC Percentage: 30%

Calculation of ITC Savings ($30,000)

$100,000 x 0.30=$30,000 (ITC Savings=Initial Cost×ITC Percentage)

By claiming the ITC, the business can reduce its federal income tax liability by $30,000. This significantly lowers the net cost of the solar installation.

Net Cost After the ITC ($70,000)

$100,000 – $30,000 = $70,000 

Therefore, the business effectively reduces its expenditure on the solar system to $70,000 after applying the ITC. This substantial saving makes the investment in solar energy more financially attractive, while also contributing to long-term energy cost reductions and sustainability goals.

Example of Savings Using the Production Tax Credit (PTC)

Let’s consider a hypothetical example of a business in Hawaii installing a solar photovoltaic (PV) system and leveraging the Production Tax Credit (PTC).

Assume the business installs a solar PV system with an annual production of 500,000 kilowatt-hours (kWh). The PTC rate is 2.75 cents per kWh.

  1. Annual Energy Production: 500,000 kWh
  2. PTC Rate: 2.75 cents per kWh (0.0275 USD)

Calculation of Annual PTC Savings ($13,750)

  1. Annual Energy Production×PTC Rate
  2. 500,000 kWh×0.0275 USD/kWh
  3. $13,750 

The PTC is available for the first 10 years of the system’s operation, so we calculate the total savings over this period:

Total PTC Savings Over 10 Years ($137,500)

  1. Annual PTC Savings×10
  2. 13,750 USD/year×10
  3. $137,500
