Solar Energy Company reviews in Seattle, Washington

We have nothing but great things to say about SolTerra. Kevin was our sales contact and he was awesome. Very understanding and patient with our questions, he walked us through the whole process. SolTerra makes the build easy. They take care of all the paperwork and permits. They are fantastic with communicating and we never felt out of the loop. Our steep metal roof in January made for a challenging installation, but once a weather window permitted, they were super fast. It only took 3 days. SolTerra is a fabulous company to work with. I highly recommended them to anyone considering going solar. We are very happy with our investment and are proud to know that we are making our own power and doing our part.

They were on schedule, provided all info I asked including gaming out different layouts and did a great job installing.

Would definitely recommend.

We love our new solar power system! The process with Solterra was incredibly smooth from start to finish. Kendall took care of all of our questions during the sales process. Jordan and Marvin went above and beyond during the design and installation phase and did exceptionally clean work. Our neighbors have been complimenting us on the clean, modern look.

I had Solterra Solar install solar panels on my roof a few months ago, and I am very happy with the results. They were professional, easy to work with, attentive to my needs before, during and after the installation. Here are just some of the reasons why I recommend them:
· They offered a free consultation and a detailed quote that explained the costs and benefits of going solar.

· They handled all the permits, inspections, and paperwork with the utility company and the city.

· They arrived on time, worked efficiently, and cleaned up after themselves.

· They installed high-quality panels that are durable, efficient, and aesthetically pleasing.

· They provided a comprehensive warranty and a monitoring system that lets me track my energy production and consumption.

· They followed up with me after the installation to make sure everything was working well and to answer any questions I had.

Solterra is a trustworthy and reliable company that delivers on its promises. I am glad I chose them for my solar project and I would recommend them to anyone who is looking for a solar installer in the Seattle area.

The Solterra team was professional, organized, and communicated clearly through out. I’m very pleased with our solar install + SPAN panels and look forward to Ph. 2 including battery backup and the new SPAN 48 install.

I recently had the pleasure of working with Solterra Solar for my home solar installation, and I am beyond impressed with their service. Initially, the installation was scheduled for March, but thanks to their proactive approach, everything was completed in February. This allowed me to start harnessing solar energy benefits earlier than expected.

My sales representative was outstanding, providing clear and transparent information about the entire process, including the expected return on investment. The communication was top-notch, and I felt informed every step of the way. I also appreciated that the final cost matched the initial estimate, with no surprise fees or hidden costs.

The install team demonstrated exceptional professionalism, respecting my property and completing the job within the agreed timeline. They ensured everything was tidy after the installation. Additionally, Solterra made the paperwork for the tax credit hassle-free, promptly sending all necessary documentation.

Overall, Solterra Solar delivered an exemplary service characterized by efficiency, transparency, and respect for both time and property. It was a seamless experience from start to finish, and I am thrilled to be utilizing solar power ahead of schedule. I highly recommend Solterra Solar to anyone considering a switch to solar energy!

SolTerra provided great customer service with coming to our home to discuss the project, gave us options to chose from, explained the ins and outs of solar power, and did a great job installing. They responded quickly to all our questions. No complaints whatsoever! Much better than any of my other home upgrades!

I was amazed by SolTerra at every step. I was contacted immediately and handed a plan for solar panels, including placement, choices, cost and benefits. Since no one else gave me a hard copy, I compared every other proposal to SolTerra, and no one came close. Communication was excellent and I knew what was happening from start to finish. Installation was fit to my schedule and 24 panels were on my roof in 3 days. I cannot say enough good things about this company. They have my highest recommendation.

Solterra has seemed an excellent solar decision for us from the start. Kendall in sales is supremely knowledgeable and operates with cost-consciousness and integrity. The installation and support teams were also professional and timely. We’re very satisfied!

We had our solar PV system and batteries installed during March 2024. SolTerra was the best value and did a fantastic and impeccable job. Marvin and his team did a great job with our project. He genuinely cared about doing a clean and precise job and treated our house like it was his own. Communication with SolTerra was clear and the process was smooth. They handled all of the planning with permitting and inspections, including with our utility company. Overall we had a great experience and have high confidence in our system!

We've used Solterra for two solar installs and both experiences have been exceptional. They are reliable, responsive and provide clear guidance and expertise during the project. We had some unusual circumstances with the first install after the panel manufacturer went out of business and the panels began to delaminate. Solterra was supportive and went above and beyond in doing what was possible to maintain the system. When it was time to replace, we chose them again and have again been satisfied with their work. Great company!

Working with Solterra was one of the best experiences we've had so far as homeowners. They were extremely responsive, friendly, and professional. We received an email every day that work occurred to summarize what was done and they kept us very well informed about each step of the process. Our roof was challenging for some solar professionals we got quotes from because we have dormers, but Solterra enthusiastically said they could make it work and followed through. We would recommend them to anyone interested in solar panels!

Recently bought a new home and planned to change the roof and perhaps add solar. Attended the Northwest Remodeling Expo in Seattle last year and met Kendall Haynes. Despite just moving in and starting to think about solar, Kendall was very patient and answered all of our questions. We asked that he reach out to us in about 6 months to see where we were at. He did and again, patiently answered all of our new questions. Things came up and more time passed. During a walk around our neighborhood one day we saw a house with a SolTerra yard sign and decided to ask how the owners felt about their decision. Their answers led us to pull the trigger and go with SolTerra. Kendall again answered all of our questions and got the ball rolling. We had two plans, one to add solar to just our house and the other to both our house and detached garage. When we found it would be challenging to add solar to our house, Kendall and his team recommended adding solar to just our house, even though adding solar to our garage would have probably been more profitable for SolTerra. The honesty was appreciated. Our installation had to be postponed a bit because of an unforeseen event on our part and the team was very flexible. The installers were professional and the electrician, Michael Marconi was great. He pointed out potential electrical safety issues with our panel which was appreciated. After nearly a year, we have our system installed and are happy. Overall, a great group of people to work with and would recommend SolTerra for those considering solar.

Although we ultimately chose a different provider, we had a fantastic experience working with SolTerra—especially with Reis, our solar system designer. Reis created thoughtful, well-optimized designs and presented a very competitive proposal. What stood out most was how clearly he explained every component of the system. He took the time to walk us through all the parts, their functions, and even the trade-offs between different manufacturers—helping us understand the long-term cost and reliability implications of each option. His expertise and transparency made us feel very confident throughout the process. We highly recommend speaking with SolTerra if you’re considering solar—they’re professional, honest, and incredibly informative.

I enjoyed Aimee’s presentation. She educated me about solar without overloading me with irrelevant info. Instead of sharing 17 different options she made an educated recommendation and confident quote based on her many years of experience I could tell she was setting realistic expectations. She was conservative with ROI and installation timeline estimates instead of over promising. The installers were very polite and professional. Operations communicated clearly and set expectations. I can’t imagine a more positive experience and now I have Good Energy in my home!

SolTerra did a fantastic job, with excellent communication throughout the process. Their price was reasonable and quality of work excellent. I've already recommended them to friends and relatives.

Solterra makes going solar so easy and we couldn't be happier with our decision! The entire team at Solterra is amazing and so responsive! Kendall went out of his way to get me a quote the same day to make sure we had the information needed to make an informed decision. He has answered all of our questions and has been very helpful and quick to respond. We also were very pleasantly surprised that they were able to get our solar system installed in April when they initially said it would likely be installed in June. Paige and the admin team also did an amazing job with getting everything set up with permits and letting us know how things were going. They took care of every little detail. We had some issues on our end with scheduling (you need to be home during the inspection) but they were able to accommodate and made the install process so easy. Additionally, several of the companies we talked to told us that system monitoring was not included but with Solterra it is. They set you up with the Enphase app and even give you an explanation of how to use it. Thank you Solterra for doing such a fantastic job!

Solterra installed a solar power system on our home in April 2025. We selected Soltera because in all of our interactions with the company, we were impressed with the knowledge and expertise of their team. Our installation went very smoothly and the team kept us informed every step of the way. The finished system looks very professional and is already offsetting most of our electrical needs, even in a Seattle spring. We have already recommended Solterra to friends and colleagues, and we are happy to recommend them here on Google as well.

Solterra made the process of adding solar to our home very easy. They provided us with all the information we needed and got us up and running as quick as they (and the City) could make it happen. We are very excited about this new upgrade to our home and in the future, not having an electric bill! I wouldn't hesitate giving them a call and seeing if it's right for your situation. Many thanks to the Solterra team!

Solterra is the best!! From the sit down with Kendall, all the way to the final walkthrough. Communication with all the staff was top notch. I couldn’t be more happier with process Solterra used to install my panels.

We recently completed a second installation on a second house with SolTerra. SolTerra has been the best company to work with. They walk you through every step of the process and explain things in easy to understand terms, responding quickly to questions and concerns. Installation is quick, efficient and aesthetically pleasing. SolTerra has my highest recommendation. I would give this company double five stars if I could.
