Western Solar Rocks

Callum helped design our system, worked through a couple hiccups with our roof. He is super helpful and knowledgeable. The Installers & electricians were punctual and fast! We are currently putting power onto the grid and couldn’t be any more pleased! Western solar is the way to go!

PV Installer that I Trust

We received five bids for our PV project, ranging from local electricians to regional solar specialists. Not only did Western Solar provide the lowest price (for Made in Washington panels/inverter), they were the only installer who designed around all roof vents and within the roofline.

Outstanding solar installers

I was very impressed with the Western Solar team. After taking care of all the permitting, they showed up on a Tuesday and finished by Thursday, a day earlier than expected. This including digging a 130ft trench for an electrical line from the array to my house, building an engineered steel ground-mount setup for the solar panels, installing the panels themselves, and wiring everything together. The installers were outstanding. The team worked well together in a professional manner. They worked quickly and built a very high quality system. Their attention to detail was impressive. I was so satisfied that I called them back several months later so that we could double the size of our array.
