Contractor installing solar

Fort Collins Utilities' Residential Solar Rebate Program created the Participating Solar Contractors Network to ensure consistent positive customer experience and support their decision-making with complete proposals and pricing details in a consistent, industry-accepted format.  

Effective June 2019: Only active Participating Solar Contractors may submit solar PV projects for the Residential Solar Rebate Program. In order to be eligible, a project must be sold, designed and installed by active Participating Solar Contractors. 

Solar PV and solar thermal system installers must register as a specialized trade contractor with Building Services to install solar systems in Fort Collins. Building Services requires a building permit application for every solar and/or battery storage installation.   

Every customer should receive the following documents with a proposal for a solar PV project: 

At a minimum, the customer must receive these documents with both the initial and final proposals for a project.
