Solar power can cut energy bills, but the upfront cost is steep. Fortunately, federal, state and local programs now make solar much more affordable, in some cases nearly free, for eligible homeowners. While no program simply hands out panels at zero cost to everyone, a combination of tax credits, rebates and grants can cover most or all of the expense for qualifying households. For example, certain state initiatives offer rebates so large that they “fully cover” the cost of a typical small system. In practice, “free” solar usually means heavy subsidies or no-money-down financing backed by government funds, not literally untaxed handouts.

To navigate these opportunities, homeowners should identify the programs they qualify for and follow each program’s application process. Below we outline major federal and state incentives, utility or local programs, and community solar options (for renters or those without suitable roofs), including who’s eligible and how to apply. We also explain what “free” really means in this context, and give concrete steps to get started.
Federal Solar Incentives
- Residential Clean Energy Tax Credit (ITC). The big federal incentive is the Residential Clean Energy Credit, which lets homeowners deduct 30% of their new solar system’s cost from their federal income tax liability. (This was authorized under the Inflation Reduction Act and runs for systems placed in service 2022–2032 at 30%.) For example, a $20,000 solar system yields a $6,000 tax credit. You claim the credit on IRS Form 5695 when you file your taxes. Note this credit is nonrefundable: you must have tax liability to use it (excess credit can be carried forward to future years). In practice, it reduces your net cost but does not come as a direct cash payment. (If you leased the panels or had a third-party install them, you generally don’t own the system and can’t take the credit.)
- Other Federal Support: The federal government also fuels programs that bring solar to low-income communities. For example, the EPA’s “Solar for All” initiative provided billions for state programs that let income‑eligible households go solar at little or no cost. (These grants fund community solar projects and nonprofit‐administered installations.) And HUD issued guidance in 2022 ensuring that subsidized renters in public housing can join community solar without risking rent increases or loss of benefits. While not a cash grant to homeowners, these efforts create new opportunities (see Community Solar below).
How to claim: To use the federal tax credit, work with your solar installer to document costs and then claim the credit on IRS Form 5695. If you owe little tax, you can carry the credit into future years (or in limited cases donate it to nonprofits). For low-income assistance programs, visit USA.gov or Energy.gov to find related grants or call your state energy office for guidance.
State and Local Incentive Programs
Many states and even local governments offer extra rebates or incentives that stack with the federal credit. You should search the DSIRE database or EnergySage Incentives Finder by zip code to see all programs in your area. Here are some notable examples of state/local programs that make solar very cheap for low-income or moderate‑income homeowners:
- California – DAC‑SASH: In California, the Disadvantaged Communities – Single-Family Solar Homes (DAC-SASH) program provides huge rebates to low-income homeowners. It pays up to $3 per watt (often covering 100% of cost) for systems up to 5 kW on qualified homes. To qualify you must own and live in a single-family home in a “disadvantaged community” (per CalEnviroScreen) and meet income limits tied to utility low-income rates. Eligible customers of PG&E, SCE or SDG&E apply through the program administrator (GRID Alternatives) – there’s an online eligibility form on Grid’s DAC-SASH page. GRID reports that “we provide low-to-no cost solar electric systems to families that qualify as low income” and that their Energy for All program offers no-cost solar for families with low incomes.
- Delaware – Green Energy Program: Delaware offers a free small system to low-income homeowners. Under the Green Energy Program, eligible low-income customers receive a free 4 kW solar installation (no cost). Moderate-income homeowners (up to higher income thresholds) can get 70% off a larger system. This is a cash grant on top of the federal credit, so a qualified Delaware homeowner could end up paying virtually nothing for solar panels grants. (Check the Delaware DNREC website for program details and contact info.)
- Washington, D.C. – Solar For All: DC’s Solar for All program covers the full cost of a rooftop solar system (up to $10,000) for income-qualified residents. The District is partnering with nonprofits to install solar on homes and build community solar projects for renters. All Solar for All participants see roughly 50% savings on their electricity bills over 15 years. To apply, DC residents can visit the official Solar for All site or contact the program hotline.
- Massachusetts – SMART: Massachusetts’ SMART incentive pays solar owners a set rate per kilowatt-hour generated, in addition to net metering. Low-income homeowners qualify for higher incentive rates (larger payments per kWh). (Income-qualified households and community solar projects fall into extra high tiers.) The SMART program requires an application before installation (through your utility’s portal). Income-qualified participants should work with a solar installer experienced in SMART to maximize their rate.
- Oregon – Solar Within Reach: Oregon’s Solar Within Reach (through Energy Trust of Oregon) adds cash incentives per watt for qualified customers of Portland General Electric or Pacific Power. As of 2025, PGE customers can get $1.10 per watt (up to $6,600) and Pacific Power customers $0.90 per watt (up to $5,400). This rebate is in addition to the federal credit, cutting the homeowner’s share substantially. Check Energy Trust’s website to see if you qualify and learn how to apply.
- Other States: Many states have solar rebate or credit programs (often listed on their energy agency or utility websites). For example, New York and Illinois each offer Solar for All programs allowing low-income families to subscribe to community solar at little or no cost. Colorado, New Jersey and other states have similar LMI solar initiatives. Programs and eligibility vary, so homeowners should check the state energy office or DSIRE for local incentives. (A good rule of thumb is to search “solar rebate” on your state public utilities or energy department site.)
Utility and Local Programs
Beyond state programs, electric utilities and local governments sometimes offer additional incentives:
- Utility Rebates and Loans: Some utilities provide extra rebates, performance bonuses, or low-interest loans to help income-qualified customers install solar. For instance, in Oregon the Energy Trust incentives mentioned above are funded by the utilities. In other states, municipal utilities or cooperatives may have their own LMI solar grants. You should contact your electric utility or visit its energy efficiency program webpage to ask about solar incentives, on-bill financing or special programs for low-income customers. (In California, utility programs like PG&E’s Self-Generation Incentive Program or local nonprofit programs can also help.)
- Community Organizations: Local nonprofits often partner with utilities or governments to run solar access programs. For example, GRID Alternatives (a national nonprofit) implements many local solar programs for low-income households in California, Colorado, Maryland and elsewhere. Reaching out to community action agencies or energy justice groups in your area can uncover pilot programs or grants not widely advertised.
- Solar Co-ops and Bulk Buys: Some cities organize solar co-ops, allowing homeowners to get group discounts. Co-ops don’t usually make systems free, but can reduce prices. Check if a community solar co-op (via a group like Solar United Neighbors) is available in your area.
Community Solar (Renters and Apartment Dwellers)
Even if you rent or can’t install panels on your roof, you can still benefit via community solar or shared solar projects. Community solar lets multiple subscribers share the output of a single solar array, receiving credits on their electric bills. Many states have special programs so low-income households can join community solar at no or very low cost:
- Community Solar “Solar for All” Programs: Several states (Illinois, New York, DC, Colorado, and others) have “Solar for All” programs that let qualifying households subscribe virtually for free. For example, Illinois’s Solar for All and New York’s Solar for All provide free or heavily subsidized community solar shares to income-eligible residents. The EPA’s funding for these programs aims to make community solar accessible to renters and low-income families.
- HUD-Backed Protections for Renters: The U.S. Department of Housing and Urban Development (HUD) issued guidance in July 2022 ensuring that HUD-assisted renters can participate in community solar without losing their affordability. In other words, if you live in public or Section 8 housing, your community solar credits will reduce your utility costs but won’t trigger higher rent or reduced utility allowances. This removes a barrier for the ~4.5 million families in HUD-subsidized housing to save money with solar.
- How to Join: To find a project, search for “community solar low income” plus your state or utility name. Utilities also often list approved community solar providers. In DC, for instance, Solar for All identifies community solar projects and handles subscriptions. In New York, the NY-Sun program’s website explains how to join community solar through Solar for All. Generally, you apply as a subscriber (often through a website or phone) and are allotted a share of a solar farm; your electricity bills then receive monthly credits from that share, usually at no upfront cost.
Eligibility: Who Qualifies for Free/Solar Programs
Qualification rules vary by program, but common requirements include:
- Income Limits: Most low-income solar programs require your household income to be at or below a certain threshold (often defined as a percentage of Area Median Income or tied to federal poverty guidelines). For example, California’s DAC-SASH requires household income below the state’s CARE program limits (roughly 80% of area median). Other programs tie eligibility to participation in assistance programs like SNAP, SSI, or free school lunches.
- Homeownership and Location: Many incentives require you to own your home and live in it. (Renters usually can’t claim federal tax credits or home-based rebates.) Programs may also be limited to certain areas – e.g. within a particular utility’s territory or, like DAC-SASH, in designated “disadvantaged” neighborhoods. Utility-specific programs (like the Oregon example) require you to be a customer of that utility.
- Housing Type: Most programs cover single-family homes. Some also allow small multifamily (with a participating owner) or community solar instead. There are separate programs for apartments (e.g. California’s SOMAH program for affordable multi-family housing, though it targets owners, not tenants).
- Installation Requirements: Many incentives only apply if a certified installer does the work. For example, California’s state rebates (DAC-SASH) must be done by a pre-approved solar contractor working with the program. Always check if the program lists approved installers or has a pre-application requirement.
Whenever possible, read the program rules or contact the program administrator directly to confirm you qualify. For example, the California DAC-SASH page provides a detailed eligibility checklist (income, utility, location) and an online form to see if you qualify. You can use eligibility checker tool to verify the same.
What “Free” Solar Really Means
No mainstream program simply gives a homeowner a solar system for absolutely nothing. Instead, “free” generally means fully subsidized by incentives so that your net cost is zero:
- Cash Rebates and Grants: Government rebates (like DAC-SASH’s $3/W or DC’s $10,000 cap) pay out before installation, covering most of the price. In those cases homeowners pay little or nothing upfront. Similarly, community solar programs for low-income often charge no subscription fee, effectively giving free clean energy credits.
- Tax Credits and Incentives: The federal tax credit is not “free money”, it reduces your tax bill by 30% of project cost. If a homeowner owes $6,000 in tax and installs $20,000 of solar, their tax bill drops by $6,000. While this isn’t cash in hand, it’s a substantial subsidy. (Programs targeting low-income do not give a cash refund; they typically take other approaches like grants or direct payments to installers.)
- Third-Party Ownership vs. Subsidy: Watch out for ads claiming “free solar” via leases or Power Purchase Agreements (PPAs). Those arrangements often put the system under a leasing company – the homeowner pays for the power, and while there’s no upfront cost, it is not a government program. And in many utility territories, third-party ownership customers cannot take advantage of the tax credit or subsidies (only owners can).
- Who Ultimately Pays: Public solar incentives are funded by taxpayers or by utility ratepayers, so in effect society is covering the bill. That’s why these programs have income or location limits – they’re targeted to help those who couldn’t otherwise afford solar.
In short, “free” solar usually means you personally pay nothing after accounting for rebates and credits. But to get those benefits, you must navigate the application process (often working with a qualified installer who handles paperwork).
How to Get Started
- Check Federal Benefits: If you plan to buy and own a system, gather quotes and plan to use IRS Form 5695 to claim the 30% tax credit on your 2025 (or later) tax return. If you owe little tax, look into carrying forward the credit.
- Find State and Local Incentives: Use online tools (like DSIRE or EnergySage’s incentives map) to list solar programs in your ZIP code. Visit your state energy office or public utility commission website for specifics. Example: California residents should check DAC-SASH or state solar rebate sites; New York residents check NYSERDA’s Solar for All; etc.
- Contact Your Utility: Ask your electric company about any solar rebates or “green energy” programs. Some, like Energy Trust of Oregon, have online portals. In many cases, an installer will know these details too.
- See If You Qualify: Look at program income and eligibility rules. If you’re low-income, focus on programs explicitly designed for that (e.g. DAC-SASH, Solar for All, state rebates). If you rent, look at community solar projects (and note HUD’s rule that these won’t raise your rent).
- Get a Solar Quote: Contact a reputable solar installer in your area. Ask them about these incentives upfront – installers often help with the paperwork. In some programs (like SMART in MA or DAC-SASH in CA) you must have a signed contract before applying for the rebate. A good installer will help you apply to the correct programs.
- Apply and Install: Follow the steps for each program: fill out online forms, provide income proof if required, and sign contracts. After installation, apply for post-installation incentives or rebates (some programs disburse funds after inspection).
- Claim the Tax Credit: When your system is live, keep records of costs. File IRS Form 5695 to claim your federal tax credit. If you qualify for any state tax credit, deduct that on your state tax return as well.
- Enjoy Savings: Once your panels are on your roof or you’re subscribed to community solar, your electric bills should drop substantially. Low-income programs often aim for 50–90% bill reductions.
Conclusion
In summary, do your research and reach out: check federal rules (IRS/ENERGY STAR), search DSIRE for your state, contact your utility’s solar program, and talk to local nonprofits or solar installers. By combining these resources, many U.S. homeowners – including low-income families – can access solar power at little to no cost.
