Low Income Solar Programs: What's Actually Available in 2026

By ClearWatt Editorial Team · Published September 21, 2026

Short answer: Low income solar programs in 2026 are mostly state- and utility-run, not federal. The 30% federal tax credit expired for homeowner-owned systems, but options like state-funded low-income solar grants, utility bill-assistance programs, weatherization funding, and community solar subscriptions can still lower costs or provide free or discounted access — availability depends entirely on where you live.

Why the landscape changed in 2026

For years, the main incentive lowering the upfront cost of home solar for any household — low income or not — was the federal residential Clean Energy Credit under Section 25D of the tax code, worth 30% of system cost with no cap. That credit was repealed by the One Big Beautiful Bill Act (H.R. 1), signed into law on July 4, 2025, and it expired for systems placed in service after December 31, 2025, with no phase-down period (Congress.gov, H.R. 1, 119th Congress). The IRS’s own guidance page on the credit reflects this cutoff (IRS, Residential Clean Energy Credit).

This matters more for lower-income households than for anyone else, because the 30% credit was one of the few incentives that scaled automatically with system cost and required no separate application. Without it, low-income buyers who want to own a system outright are now leaning much more heavily on state programs, utility assistance, and financing tools — several of which are covered in more detail in our state solar incentives guide.

One partial exception: homes that get solar through a lease or power purchase agreement (PPA) don’t own the system, so the company that owns it may still be able to claim a separate commercial credit under Section 48E of the tax code. Whether and how much of that value gets passed through to the household in the form of lower monthly payments is up to the leasing company, not guaranteed by law, and worth asking about directly — see our comparison of solar loan, lease, and PPA options for how third-party ownership actually works financially.

Federal programs that still exist (outside the tax credit)

The tax credit’s expiration doesn’t mean every federal support for low-income solar disappeared. A few programs operate on separate legal authority:

• Solar for All. This initiative was funded through the EPA’s Greenhouse Gas Reduction Fund and directed grant money to states, tribes, territories, and nonprofits specifically to expand low-income and disadvantaged-community access to solar. Awards and rollout timelines vary by grantee, and federal budget changes in 2025 affected multiple clean-energy funding streams, so confirm current status with your state energy office or the EPA rather than assuming a specific local award is still disbursing funds.
• Weatherization Assistance Program (WAP). Run through the U.S. Department of Energy and delivered by state and local agencies, WAP funds home energy-efficiency upgrades for income-qualified households. It’s not a solar program per se, but some state agencies have paired weatherization funding with solar or battery pilot projects, and reducing home energy use first is usually the more cost-effective step before adding solar.
• LIHEAP (Low Income Home Energy Assistance Program). Administered by the Administration for Children and Families within HHS, LIHEAP primarily helps with heating and cooling bills, not solar installation, but it’s often the entry point that connects a household to other state energy-assistance resources, including any solar set-asides.

Because eligibility rules, funding cycles, and even whether a program is currently accepting applications change frequently, the most reliable way to check current status for any of these is your state energy office or the program’s own site, not a general web search.

State and utility-level programs

This is where most of the real savings for low-income households now show up. States set their own rules, and they vary enormously — some have dedicated low-income solar grant or discount programs, some rely on net metering rules that favor smaller systems, and some have nothing beyond the standard incentives available to any homeowner.

California is a useful example of how deep state involvement can go: the state’s investor-owned utilities have historically operated income-qualified solar programs overseen by the California Public Utilities Commission, alongside the state’s separate rules on net metering and interconnection (California Public Utilities Commission). Other states run more limited rebate or low-interest loan programs targeted at income-qualified homeowners, often administered through the state energy office or a state housing finance agency rather than through the tax code at all.

Because there is no single national database that captures every local program accurately in real time, the practical move is to search the U.S. Database of State Incentives for Renewables and Efficiency, which is maintained specifically to track this kind of program by state (DSIRE). Our own state solar incentives guide walks through how to use that database effectively.

Community solar: an option when you don’t own the roof

Many low-income households rent, live in multifamily housing, or have roofs that aren’t suitable for solar (too much shade, an aging roof, or a homeowners association that restricts installations). Community solar offers a workaround: instead of installing panels, you subscribe to a share of output from a solar array located elsewhere, and that share shows up as a credit on your electric bill.

Some state-run or utility-run community solar programs specifically reserve a portion of subscriptions for income-qualified households, sometimes at a bigger discount than what’s offered to standard subscribers. Availability is entirely dependent on whether your state has authorized community solar and whether a program near you has a low-income carve-out. Our guide to community solar for renters covers how to evaluate a subscription offer, including the fine print that matters most (cancellation terms, escalator clauses, and whether credits are guaranteed).

Financing routes when a grant or rebate isn’t enough

Even with a program discount, many low-income households still need to finance some portion of a system. Traditional solar loans typically require a credit check and a reasonable credit score, which can be a barrier. A few alternative paths exist:

• PACE (Property Assessed Clean Energy) financing, where repayment is attached to the property tax bill rather than underwritten like a conventional loan. It can be easier to qualify for but carries real risks and costs that are frequently misunderstood — our article on solar financing with bad credit breaks down what PACE actually costs versus what it’s marketed as.
• On-bill financing or utility-administered loan programs, where a state or utility offers below-market financing repaid through the electric bill.
• Leases and PPAs, which avoid upfront cost entirely in exchange for a long-term contract with the solar company, and which may indirectly retain some tax-credit value under Section 48E even though the homeowner can’t claim it directly (EnergySage, solar leases vs. PPAs).

Whatever the financing route, the Federal Trade Commission’s consumer guidance on solar purchases applies just as much to income-qualified buyers as anyone else: get multiple quotes, read the contract before signing, and be skeptical of any offer described as “free solar panels,” since a lease or PPA is a long-term contract, not a gift (FTC, Solar Power for Your Home).

A rough comparison of program types

The table below is a general framework, not a promise of what’s available in any specific location — actual terms depend entirely on your state and utility.

Why energy costs make this worth pursuing

Lower-income households often spend a larger share of their income on home energy bills than higher-income households, a pattern the U.S. Energy Information Administration has tracked through its residential energy surveys (EIA). That’s part of why federal and state policymakers have specifically targeted low-income solar and efficiency funding rather than relying solely on the general tax credit, which mainly benefited households with enough tax liability to use it and enough upfront cash or credit to finance a system.

What to do next

Start with your state’s listing on DSIRE, then check with your utility and your state energy office directly, since program funding and application windows change throughout the year. If a program isn’t currently accepting applications, ask about waitlists rather than assuming the door is permanently closed. And if a contractor or salesperson tells you that you qualify for a specific low-income program, ask for the program’s name and verify it independently before signing anything — the FTC’s guidance on avoiding solar sales pressure applies with extra force to programs marketed as “free” or “government-backed.”
