Very happy with Cascadia Solar PV installation!

Cascadia Solar/Frederickson Electric did a fantastic job on our new solar PV system. They were prompt completing the site evaluation and putting together the proposal. The system was well designed, with high quality components. The installation was completed as scheduled by their highly professional and courteous crew, and the system looks and works great! We're very happy customers!

Cascade Solar installation and performance.

We started our solar adventure with Cascade Solar in the spring of 2022 with an interview, consultation and planning session. Estimating our solar needs was the first step. Our 28 panel system was installed in three days with very little interruption of our daily lives. The county installed our meter on July 15 so we are approaching one year of solar power. With the exceptional sunny spring weather, we have experienced we have produced more than originally projected for our first year. If the rest of the summer produces like last yea,r I project we will go into the "long cold dark" PNW winter with a "bank" of over 500 kwh. This should cover nearly 90% of our projected electrical usage. This would be 13% more than our original projection of 77%. The people at Cascade Solar are pleasant and easy to work with. All around a great experience.

17kw system in Sequim, WA

I recently had the pleasure of working with Cascadia Solar, and I must say that I am thoroughly impressed with their professionalism, expertise, and commitment to excellence. They designed and installed a 17kw solar panel system for my new shop in Sequim, WA. Brian Thornberry, my primary contact at Cascadia Solar, was an absolute pleasure to work with. He was knowledgeable, attentive, and responsive to all of my questions and concerns. He took the time to explain every aspect of the installation process in detail, and he kept me updated every step of the way. Overall, I couldn't be happier with my experience with Cascadia Solar. They exceeded my expectations in every way, and I would highly recommend them to anyone in need of solar panel installation services. Thank you, Cascadia Solar, for your outstanding work!
