How to Finance a Solar Project: Grants, Tax Credits, and Incentives

Investing in solar power is one of the smartest moves a farm or rural small business can make. Solar not only reduces electricity costs, it also provides long-term stability against rising utility rates. While the benefits are clear, the question most business owners ask is: How do I finance a solar project without overwhelming my budget?

The good news is that several programs exist to make solar projects more affordable, including grants, tax credits, and financing strategies. At CGF, we help our partners navigate these opportunities to maximize funding and minimize out-of-pocket costs.

USDA REAP Grants: A Strong Starting Point

The USDA Rural Energy for America Program (REAP) grant is one of the most valuable tools available for rural businesses and agricultural producers. It provides up to 25% of total project costs for renewable energy systems like solar. (7 CFR §4280.122(a)(3)) Grant requests for renewable energy systems run from $1,500 to $500,000. (7 CFR §4280.122(a)(2))

That means if your finished solar installation cost $200,000, the REAP grant could cover as much as $50,000. (7 CFR §4280.122(a)(3))

Timing matters under the new REAP rule published October 1, 2026. The grant comes after the project is done. The project must be completed 12 to 24 months before you apply, or 12 to 36 months for the first application window. (7 CFR §4280.122(a)(1), (a)(6)) So you need a plan to pay for the full system first, with cash, a loan, or other incentives.

The REAP grant can be combined with other incentives, making your project even more affordable. A few REAP limits apply. Your REAP grant and any REAP guaranteed loan together cannot top 75% of the project cost. (7 CFR §4280.122(b)(20)) Costs paid by another federal award cannot be counted in your REAP project. (7 CFR §4280.125(b)(19)) And ground-mount solar on cropland is not eligible for REAP. (7 CFR §4280.122(b)(11))

Federal Solar Tax Credit (ITC)

Alongside REAP, the federal Clean Electricity Investment Credit, still often called the ITC, lowers the federal income tax you owe dollar for dollar. It is a credit, not a deduction. The base credit is 6% of the qualified investment, and it rises to 30% for projects that meet prevailing wage and apprenticeship requirements (IRS). Solar systems under 1 megawatt (AC) can get the 30% rate without meeting those wage requirements (IRS).

Watch the deadline. The 2025 federal tax law ends this credit for solar placed in service after December 31, 2027, unless construction began by July 4, 2026 (IRS Notice 2025-42). Confirm your project’s timing and credit amount with your tax advisor.

Using the earlier example, if your project qualifies for the full 30% credit:

• REAP grant covers up to 25%
• The federal tax credit covers 30%
• That’s up to 55% of your project covered before considering other incentives.

Bonus Depreciation and MACRS

Farmers and businesses can also take advantage of accelerated depreciation through MACRS (Modified Accelerated Cost Recovery System). Solar property that qualifies for the Clean Electricity Investment Credit is generally 5-year property, so you can deduct its cost over a short period (IRS). When paired with bonus depreciation, which may let you deduct much of the cost in the first year (IRS Publication 946), the tax benefits can be substantial, creating significant cash flow advantages.

State and Utility Incentives

In addition to federal support, many states and utility companies offer rebates, performance-based incentives, or renewable energy credits (RECs) that can reduce upfront costs or provide long-term payments for your solar production.

Financing Options Through CGF Partners

Even after grants and tax credits, some businesses need additional capital to cover remaining costs. That’s where financing options come in. CGF partners have access to specialized solar financing programs, designed for farms and rural businesses, that can spread costs over time and align payments with the savings solar generates. If you plan to apply for REAP, pick financing that leaves your business owning the system. Leases and power purchase agreements, where someone else owns the panels, do not work for REAP. (7 CFR §4280.120(a)(6); §4280.125(b)(6)) Learn more on our project financing page.

By stacking REAP, tax credits, depreciation, and financing, many clients see their solar projects pay for themselves much faster, sometimes in just a few years.
