NW Electric & Solar is the Tesla certified installer in WA that Tesla choose to install their solar system. Initially I got the quote online at the Tesla Website. NW E&S written estimate came in very close to Teslas estimate.

They installed 20 solar panels and 2 Tesla power walls in a little over 2 days. They did a great job the workmanship was very professional. The system works great. Would highly recommend them

This is my second solar system in my life. And by far the best!

The team over at north west solar is great to work with and the quality work speaks for itself. They installed a beautiful 19kw system , Tesla charger , Tesla power walls for my home. 2 years later running strong! And there support after the fact has been the best. And they came all the way to eastern Washington !

Had a great experience with Northwest Electric and Solar. Ian was the electrician, and had a fairly complicated job to do (install a Tesla Powershare, whole house backup switch, and keep my generator inlet functional) at my house. He was polite and friendly and took the time to explain everything about what he was doing. He even cut the drywall so precisely that I didn’t have to patch anything up afterwards. The project manager (Giancarlo) was also responsive and was able to incorporate several non-trivial changes without changing the original estimate.

David and his team of Evie, Paul, and Denis installed a battery backup system in my home recently, and it has been great. Timely install and quality work (clean looking install in the garage), and the backup provided seamless power during a recent outage.

I’ve been absolutely blown away by the level of work NWES has done for my solar install and Powerwall backup system. Everyone that I have interacted with has been very punctual, professional, and knowledgeable. They did an absolutely fantastic job installing the solar panels and the Powerwalls in terms of aesthetics and quality and accommodated my concerns about the placement of each component. NWES will be my go to in terms of recommendations for anyone that is looking for solar installations in the greater Seattle area.

Battery FAQs

  • What happens when there is a power outage? Do I have to turn my battery backup on manually?

    Up and Down Chevron

    Tesla, FranklinWH, and Enphase battery storage systems automatically turn on backup energy whenever a power outage occurs. Like the Automatic Transfer Switch used with gas generators, battery energy storage systems allow you to seamlessly transition to backup power, followed by a notice on your companion app for your respective battery manufacturer.

  • If I purchase a battery energy storage system without solar can I still qualify for the 30% investment tax credit?

    Up and Down Chevron

    Yes! Stand-alone battery energy storage systems qualify for the 30% Federal Investment Tax Credit.

  • Is stand-alone battery backup eligible for the Washington sales tax exemption?

    Up and Down Chevron

    No, installing a battery on your home without solar, whether at the same time or installed previously, will not be eligible to receive the Washington sales tax exemption.

  • How many home loads can I cover with partial backup?

    Up and Down Chevron

    Partial backup can cover up to 120A worth of breakers. Depending on the battery storage manufacturer, the 120A breakers can be no larger than 30A for Powerwall and 20A for Enphase IQ batteries. Large loads such as AC units and laundry typically use 50A breakers, and if you want to use these appliances during a power outage, adding at least two to three batteries is recommended. We can help you find the correct battery backup configuration to meet your needs!

  • Do you offer a referral program if I send friends to you for a battery storage system?

    Up and Down Chevron

    Yes! We offer $100 per battery unit if your referral installs a battery storage system. If they install two Powerwalls, you will get $200.
