CCSE recommends evaluating at least three (3) different contractors. Download our Homeowner Bid Comparison Worksheet and consider the following:
- Check the status of Contractor License at www.cslb.ca.gov- License must be an active A, B, C-10, or C-46 in order to meet the eligibility requirements for the CSI Program.
- Check references- One of the most reliable sources for business references is the Better Business Bureau (BBB).
- Examine customer feedback- Conduct internet searches, talk to those who may have used this contractor, etc. in an effort to find out as much information as possible.
- Get detailed project information for the California Solar Initiative- See what the average project costs, how much contractors charge per watt, etc. by downloading our program data here.
