City of Boulder Solar Grant

Grants for income-qualified resident homeowners are available.


Funds generated by the Solar Rebate Ordinance are used to provide grants for the installation of solar systems (photovoltaic and thermal) on individual housing units owned and occupied by low-to-moderate income-qualified residents.

In order to participate in the city’s solar grant program, you must live within Boulder city limits and be enrolled in EnergySmart. EnergySmart is Boulder County’s free residential sustainability program.

Solar grants are subject to funding availability.

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