Solar Installers & Interconnecting

Selecting an Installer

When choosing a contractor/installer, consider the following:

  • How much and 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.

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 Proceed with the solar installation, following all local codes and permitting requirements.
5 After your electrical permit has been finalized, submit the Notice of Completion to the PUD.
6 The PUD will set new solar meters.
7 The PUD will execute your Net Metering agreement
8 If intending to participate in the state’s production incentive program, you will need to certify your system with WSU (click here for details) and then provide a copy of the certification letter or email to the PUD.
