We speak


We serve our customers for the longevity of their system. Once a year we will offer a Spring Cleaning service to maximize the production of your solar array. In this service we clean the solar modules, remove debris under the module, and visually inspect the wires and connections where accessible. In addition, we provide critter guards, for homes where squirrels or birds need to be deterred from nesting under the solar array; system expansions, in case the in-laws or kids move back in and you need to increase your solar production to off-set your energy bill; and for our longest-term customers, we offer a very reasonable uninstall/reinstall service for when the roof needs to be replaced before the solar modules (which is usually the case).

The best solar company in Whatcom County

Western Solar installed our solar array in 2017. The knowledge and professionalism of the team was outstanding. The install went very smoothly. I really appreciate that they have a full-time service department to help when I have questions on cleaning, maintenance or any kind of issue with my inverter.

Excellent, personalized, customer device together with very friendly,efficient installation team.

I chose Western Solar on the recommendation of a neighbor. I am very happy I did so. The entire project was made simple because of the comprehensive service provided by Western Solar. From low cost financing to quick,quality design and installation using excellent technology, to outstanding customer communication. I could not be happier with the company. I am now a power producer due to the excellent work of Western Solar.

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.
