Very good daily communication about the project.This was a more completed solar installation with multiple parties to interface with. There were a number of issues that arose during the construction which were quickly and completely resolved to my complete satisfaction. Good job all around.

Very satisfied with Western Solar from the time Callum came out, through the process of choosing our individual system and final electrical and panel install. Office staff was extremely helpful and quick to respond to every question I asked. Very good company to deal with!

Working on a historic house, parts of which are over 125 years old, can create problems for securing panels. Western Solar spent the time and effort to complete the project, even a month early! So now the Tennant house overlooking Tennant Lake in Ferndale WA has Western Solar panels producing green power!
