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 Solar section.

All applications for the spring 2015 Solar Grant funding cycle are due by 5 p.m. on Thursday, April 30.

  • the facilities of site-based nonprofit organizations;
  • low- or moderate-income housing owned by nonprofit organizations; or
  • individual residences that are part of an affordable housing program.
