Low-Income Solar Programs: LIHEAP & DAC Benefits Explained

Going solar has historically felt out of reach for millions of American families. The upfront cost of a rooftop system — typically $15,000 to $25,000 before incentives — is a real barrier for households already stretched by rising utility bills. The good news: a growing network of federal, state, and utility programs are specifically designed to put solar savings within reach for low-income and disadvantaged community (DAC) residents, often at little to no out-of-pocket cost.

This guide walks through the major low-income solar pathways in 2026, what they actually cover, and how to combine them with EnergyScout's free tools to find every dollar of help you qualify for.

Why low-income solar programs exist

According to the U.S. Department of Energy, lower-income households spend up to three times more of their income on energy than the median household — a gap researchers call the "energy burden." Lawrence Berkeley National Laboratory's 2024 low-income solar tracker found that households earning under 80% of area median income (AMI) represent roughly 43% of U.S. residences but account for only about 15% of residential solar installations.

Closing that gap is the explicit goal of programs like LIHEAP, DAC-SASH, and the Inflation Reduction Act's Low-Income Communities Bonus Credit. These aren't charity — they're infrastructure investments that reduce utility grid strain, create local jobs, and lower long-term costs for everyone on the grid (NREL, 2024).

Federal program #1: LIHEAP and weatherization

The Low Income Home Energy Assistance Program (LIHEAP) is the oldest and largest federal program helping low-income households with energy costs. Administered by HHS and distributed through state agencies, LIHEAP served approximately 5.9 million households in fiscal year 2024 (HHS Office of Community Services).

What LIHEAP covers

• Bill payment assistance — direct payments to utilities to cover heating and cooling bills
• Crisis intervention — emergency help when service is about to be shut off
• Weatherization referrals — LIHEAP often hands off to the DOE's Weatherization Assistance Program (WAP) for deeper home energy upgrades

While LIHEAP itself does not typically pay for rooftop solar panels, the linked Weatherization Assistance Program has expanded in several states to include solar photovoltaic (PV) systems when it's the most cost-effective way to reduce a household's long-term energy burden. Since 2023, DOE guidance permits WAP grantees to fund solar PV as a renewable energy measure where it produces positive net present value over the system's life (DOE, 2024).

Who qualifies

LIHEAP eligibility is typically capped at 150% of the federal poverty level or 60% of state median income, whichever is higher. States set their own rules, so a family of four earning up to roughly $46,000–$55,000 may qualify in most states.

Federal program #2: IRA Low-Income Communities Bonus Credit

Here's an important clarification: the federal 30% Investment Tax Credit (ITC) for purchased residential solar expired at the end of 2025. Homeowners who buy a system outright in 2026 can no longer claim that credit. However, systems financed through solar leases and power purchase agreements (PPAs) still qualify because the commercial ITC remains in place — the tax credit flows to the installer/financier, who passes savings through in a lower monthly rate.

Importantly for low-income households, the IRA's Low-Income Communities Bonus Credit adds an additional 10–20 percentage points on top of the commercial ITC when a solar project is located in:

• A low-income community census tract (+10%)
• Tribal land (+10%)
• A qualified low-income residential building project (+20%)
• A qualified low-income economic benefit project where 50%+ of savings pass to low-income households (+20%)

This bonus is why many third-party lease providers can now offer zero-down solar to income-qualified homeowners with bills lower than what they currently pay the utility (SEIA, 2024).

State spotlight: California's DAC-SASH program

California runs one of the nation's most generous low-income solar programs: the Disadvantaged Communities — Single-family Solar Homes (DAC-SASH) program, administered by GRID Alternatives on behalf of the California Public Utilities Commission (CPUC).

What DAC-SASH covers

• 100% of system installation costs for qualifying homeowners — no loan, no lease, no money down
• System sizing targeted to offset the household's actual usage
• Ongoing education and job training for community members

Who qualifies

To qualify, a homeowner must (1) own and occupy a single-family home, (2) be a customer of PG&E, SCE, or SDG&E, (3) live in a census tract identified as disadvantaged by CalEnviroScreen, and (4) have a household income at or below 80% of area median income. The CPUC extended DAC-SASH funding through 2030 with a budget of roughly $8.5 million per year (CPUC Decision 21-09-001).

Since launch, DAC-SASH has installed over 10,000 systems saving participating families an estimated $90 million in lifetime utility costs, according to GRID Alternatives' 2024 annual report.

Other state and utility low-income programs

Beyond California, several states have launched or expanded equity-focused solar programs. A snapshot of notable examples:

Illinois Solar for All

Funded under the Climate and Equitable Jobs Act, Illinois Solar for All provides no-cost rooftop and community solar subscriptions to income-qualified households, guaranteeing customers save at least 50% compared to their utility bill. As of 2024, the program has enrolled more than 9,000 low-income subscribers (Illinois Power Agency).

New York NY-Sun Affordable Solar

NYSERDA's NY-Sun program offers enhanced incentives — up to $1.00 per watt additional — for projects serving low-to-moderate income households, along with streamlined community solar access for renters and multifamily residents.

Massachusetts SMART low-income adder

The Solar Massachusetts Renewable Target (SMART) program adds $0.06/kWh on top of base compensation for systems serving low-income households, effectively doubling typical payback for qualifying participants (Mass DOER).

Colorado Weatherization + Solar

Colorado's Energy Office bundles solar PV into its weatherization program for income-qualified homeowners, covering 100% of installation at no cost to the household.

Community solar: the option for renters

If you rent, live in a condo, or have a shady roof, community solar is often the best path. Instead of installing panels on your own home, you subscribe to a share of a local solar farm and receive bill credits. According to the EIA, community solar capacity grew to roughly 7.9 GW across 44 states by the end of 2024, with dedicated low-income carve-outs in states like Colorado, Illinois, Maryland, Minnesota, New Jersey, New York, and Oregon.

Many programs guarantee savings (often 10–20% off your effective rate) with no upfront cost, no credit check, and month-to-month terms.

How to combine programs and maximize savings

The savviest low-income households stack multiple programs. A typical winning combination looks like:

1. LIHEAP — immediate bill assistance to stabilize your account
2. Weatherization Assistance Program — free insulation, air sealing, and efficient appliances that cut load before going solar
3. State low-income solar program (e.g., DAC-SASH, Illinois Solar for All) — fully subsidized rooftop system or no-cost community solar subscription
4. Ongoing net metering or SMART credits — monthly utility bill credits from exported solar energy

How EnergyScout helps you find what you qualify for

Navigating dozens of overlapping federal, state, and utility programs is overwhelming. EnergyScout's tools exist to take the guesswork out of the process:

• Start with our free solar assessment tool to see system size, production estimates, and realistic savings for your specific address using NREL's PVWatts model.
• Use the incentive search by ZIP code to surface every rebate, credit, and low-income program available where you live — including LIHEAP, WAP, and state equity funds.
• Connect with vetted local installers through our providers directory. Many participating installers specialize in income-qualified lease and PPA options that still qualify for the commercial ITC.

The bottom line

Solar is no longer a privilege reserved for high-income homeowners. Between LIHEAP, weatherization, the IRA's low-income bonus credit, DAC-SASH, Illinois Solar for All, community solar, and dozens of state programs, a household earning under 80% of area median income can often go solar for $0 down with guaranteed savings on day one. The hardest part is knowing where to look — and that's exactly the problem EnergyScout was built to solve.
