Solar Rebate and Solar Grant Programs

Solar Rebate and Solar Grant Programs

Solar Rebate

Boulder residents and businesses that have installed solar electric or solar thermal (hot water) systems on their property may be eligible for a sales and use tax rebate. The city may rebate approximately 15 percent of the city sales and use tax paid on materials and permits for the solar installation. To be eligible, taxpayers must file a rebate application within 12 months of the city's final inspection. For even more resources on solar in the city see the solar page.

Solar Grant

Notice: the City of Boulder Solar Grant Program application cycle frequency and time of year is changing. There will not be a fall 2019 application cycle and starting in 2020, there will be one application cycle annually, opening in late spring/early summmer. Please check this page going foward. It will be updated as more information becomes available.

Funds generated by the City of Boulder's Solar Rebate Ordinance are used to provide grants for the installation of solar electric and solar thermal (hot water) systems on:

  • The facilities of site-based nonprofit organizations and nonprofit organizations that lease city-owned facilities;
  • Low/moderate or middle income housing owned by nonprofit organizations; and
  • Individual residences owned by low/moderate and middle income residents as defined under the Solar Grant Evaluation Criteria.

Grants are subject to funding availability.

Please consult the IRS or a tax professional regarding potential tax consequences for grant recipients.

Solar Grant Committee

The Solar Grant Committee (SGC) is comprised of members who possess knowledge of vital program elements such as solar installations, policy and financing, nonprofit organizations and affordable housing programs. The SGC consists of five to nine members selected by staff, each to a three-year term, with the option to continue to serve an additional three-year term. The committee reviews solar grant applications, awards grants and discusses ways to continually improve the Solar Grant Program’s effectiveness. Meetings are usually held twice a year; once in the spring (typically in May) and once in the fall (typically in November), with occasional email correspondence as necessary.

The City of Boulder is not currently seeking new members to serve on the committee.
