LEARN ABOUT SOLAR
Benefits of Solar
Solar energy is abundant, low-emission, and a clean alternative to fossil fuels. As cities grow and energy costs rise, solar provides 30+ years of protection from rate hikes and power outages.
It also boosts property value, requires minimal maintenance, and offers incentives and savings when excess electricity is sent back to the grid.

How Solar Works
Solar panels capture sunlight and convert it into clean, usable energy—even on cloudy days. Washington’s long summer days, cooler climate, and frequent rain make it an ideal place for solar systems to operate at peak efficiency.

How Much
Does Solar Cost?
Solar is a smart investment. With federal and tax incentives, low-interest loan programs, and the potential for significant increase in property value, going solar is a secure, financially sound decision for any property owner.
The cost to generate solar energy is already on par with current utility rates, and as electricity prices continue to rise, solar shines as an even better choice.

Super happy to have chosen Solterra to design and install our panel array! The whole process was seamless from start to finish. Kendall visited us personally to go over our choices, explain how the array would help us power our future home improvements, and discuss the nerdier aspects of generating our own power. The installation team was quick, efficient, and fun, and we really could not be happier with the performance and seeing our new electric bill. Give Solterra a call if you're looking to harness the power of the sun, they'll be honest and transparent with your options and they care about how their system performs not only when you install but down the line as well.

Crew was great to work with. Any trash items dropped on the ground were immediately picked up. They arrived on time each morning. Everything looks level and even on both ends. Had 39 panels installed.

Two preliminary visits, pretty quick install date, two days to install everything, inspection the next work day, net metering visit and start 3 days later. Really couldn't have been happier. Production great so far, first bill was $0 with only half a period covered by solar. Now for the darker months.

We had an outstanding experience with SolTerra, thanks largely to our installer, Marvin. He was incredibly knowledgeable, gave us clear instructions throughout the process, and worked quickly and efficiently while staying completely focused on the job. He showed up on time and was polite and easy to work with from start to finish.
Marvin went above and beyond to help us with our solar panel installation, and it really showed. He's top-tier for this company and deserves real recognition for it a raise, a bonus, or a move into management would be well earned. We feel very lucky to have had him on our home.
The rest of the crew was excellent too. They worked hard through the August heat (we made sure to keep them stocked with water installing solar panels in that kind of weather is no joke), and the whole team's effort didn't go unnoticed.
Thank you for sending such a great crew our way. Our family will be recommending SolTerra to everyone we know.

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.

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.

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!

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!

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!

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.
