I'm not one to typically leave reviews. But this company deserves a little shout out. Power Northwest is simply the best! They were very knowledgeable, easy to work with (answering my million and one questions), and competitively priced. I did a ton of research and they truly offered the best system at a very fair price. They also made the entire process easy from start to finish. After working with them I got the feeling that they had my best interests in mind. Without even asking, Power Northwest designed an array that would be efficient and aesthetically pleasing. As much as I love the idea of solar, I was a little worried that the panels would stick out like a sore thumb. I couldn't have been more wrong. They explained some of the features that make them unique and it was stuff I would not have even thought of. For example, they ran all of the wiring so that it was hidden as opposed to running it across the roof. They explained that this was more difficult and took more time, but that it was important to them that the finished product looked great. They also offer a 10 year Production Guarantee which means that when they estimated the return on my system if it ever falls short of what they say it'll produce, they will pay us back for any shortages on production. It made me feel safe, knowing that they truly stand behind their designs. Absolutely a pleasure to work with. Could not be happier. Now I don't feel as guilty having 10,000 Christmas lights strung up around my house :-) I would highly recommend them to anyone!
