Solar Installers & Interconnecting

Selecting an Installer

When choosing a contractor/installer, consider the following:

  • How much/what type of solar experience do they have?
  • What references do they provide?
  • What types of warranties and maintenance agreements do they offer?
  • Do they work with specific suppliers or components that are important to you?
  • Once you have the bid(s) be sure that they are all based on similar system and design criteria.

Although it is not required that you use one, your PUD maintains a list of Registered Solar Installers. Click here to view the list.
Because of Restraint of Trade restrictions, Snohomish County PUD cannot recommend or endorse any individual installer who appears on the list.

What Is the Process to Interconnect with the PUD?

1 Get an assessment from a solar contractor to determine if your home/business is a good candidate for solar
2 Get one or more project bids
3 Submit an Interconnection Application and a Net Metering agreement (available at right)
4 Your project submission is reviewed – if acceptable, we will issue an Approval to Construct for your project
5 Proceed with the solar installation, following all local codes and permitting requirements
6 After your electrical permit has been finalized, submit the Notice of Completion to the PUD
7 The PUD will set new solar meters
8 The PUD will execute your Net Metering agreement
