Installing a Solar System
-
Choose a solar installer
Work with a licensed, bonded, and insured solar contractor. We encourage everyone to get several bids so you can make an informed decision.
Washington Solar Energy Industries Association Contractor list
Tacoma Power does not partner with or endorse individual solar installation companies.
-
Apply for an electrical permit
Before installation begins, your contractor must apply for an electrical permit from Tacoma Power. If you own and live in the home and plan to do the electrical work yourself, you may apply for the permit directly (TMC 12.06A.230)
-
Submit the Solar Application
After you obtain the electrical permit, your contractor must submit the Tacoma Power Solar Application and Interconnection Agreement, along with the required supporting documents.

Complete installation and inspection
Your system must meet Tacoma Power’s electrical requirements and pass the required inspection before connecting to the electric grid.
How net metering works
When your solar panels produce electricity, your home or business uses that energy first. When you need more electricity than your system produces, you recieve electricity from Tacoma Power.
If your system produces more electricity than you use, the extra electricity is credited to your Net Meter Bank and can help offset electricity you use later. Your Net Meter Bank resets each year on March 31st, as required by Washington state law.
