Working with Solterra has been amazing and seamless. We had multiple companies give us bids and Solterra won hands down. They were knowledgeable and were able to answer all our questions. From start to finish of the project, they walked us through each step, layout a timeline that they met. We are so happy with the product and even more so with the service. Thank you Solterra!

I highly recommend Solterra Solar for solar panel installation in Seattle! After receiving four bids, Solterra stood out from the start. Macie came to discuss the plan, walked my roof, and asked if I had any concerns. Later, the project manager and electrician inspected my electrical panels and roof to ensure everything was safe for installation.
The installers were efficient and friendly, and the electrician, Mike, was incredibly helpful—he explained the process clearly and guided me through the Enphase app setup. Once everything was complete, Macie returned to review the work, provided a disc drive with all documentation, and made sure I was satisfied.
Solterra truly focuses on customer care, safety, and a smooth installation process. Everyone I worked with was amazing! If you’re looking for solar panels in Seattle, I highly recommend Solterra.

We had a fantastic and seamless experience with Solterra.

Our install was seamless and ahead of schedule. Everyone at the company was very nice and informative, taking time to educate us on the system itself and the integration with our local utility.

Aimee is probably wondering where this review is. Especially since I wrote this 9 months ago. The bottom line is I was waiting for the one year anniversary of our system so I could properly analyze the performance of the system.

At one year we produced 14.2(-ish)MWh, from a system that was designed for 12.4(-ish)MWh performance after 25 years. The “overproduction” is also in part due to moving some panels from west to south facing. Running the numbers, it is exactly what should have been produced.

The actual consumption was a good bit lower than the design for a couple of reasons. First, we replaced our roof as “part” of the solar installation. This actually reduced our heating and cooling needs, since our attic finally had ventilation. We also added an EV to our home, estimated at 3MWh, but we don’t really drive as much as “normal” people. Lastly, Solterra added a Span smart electric panel at our request, and I enjoyed turning off circuits remotely while we were away from home.

The bottom line here is that we still have 4.4MWh of excess production. Even knocking 15% off the total at 25 years (higher than the 8% the REC panels specify), we will have over 2MWh to “burn.” Looks like we are going to consider replacing the gas stove and tankless hot water heater with electric!

Finally, I can’t say enough good things about the installation team. Super professional, and worked well with my roofer to route the wiring around the end of the roof and avoid penetrating the roof. We have even had them return to install the EV charging plug.

SolTerra did a fantastic job with our solar installation. The entire process was a great experience - professional, clear and timely communications, great customer service. They provided lots of information and options regarding what they could offer us, and I'm very pleased we went with them. In addition they were super helpful with financing with a partnership with PSCCU. The panels were install ahead of schedule and have been working flawlessly. We are extremely happy with the results!
