Your application paperwork

Washington's Solar for All program, funded through the federal Greenhouse Gas Reduction Fund, brings the benefits of solar to income-qualified residents. It offers no-cost solar installations for income-qualified single-family homeowners and no-cost community or shared solar participation for renters. The Department of Commerce runs it through selected program partners.

Steps to apply

  1. Confirm you are an income-qualified Washington homeowner (or a renter interested in community solar).
  2. Visit the Commerce Solar for All page to find the current program partners and how to enroll.
  3. Contact a participating partner to check eligibility and start enrollment.
  4. If eligible, the partner arranges the no-cost solar installation.

Documents you will likely need

  • Proof of household income to confirm you are income-qualified.
  • Proof you own and live in the home.
  • A recent electric bill.
  • A government-issued photo ID.

Requirements vary by program and locality. Confirm the exact rules on the official program page. We can help you prepare your paperwork, but you submit it yourself.
