I want to wholeheartedly endorse Big Dog Solar.
I got my system a few years ago and the savings are very significant compared to what my power bills would be without the system. My neighbor, with a comparable sized home, paid SEVEN TIMES what I did in electrical costs this winter.
When I first contracted for my system, Big Dog Solar handled all the engineering, permitting and power company integration tasks. The actual installation was quickly and very competently done.
Even during snow, ice, high winds & other harsh conditions, my system has functioned perfectly. The company recently detected a monitoring issue after a recent power surge that knocked out a large number of other systems in the area. They detected it from their monitoring & asked me to go to the controller to help trouble-shoot. Unfortunately, I am handicapped and cannot do even such a simple task. No problem, they said, and immediately scheduled a technician to come check the system. A tweak later and a couple more to further optimize the system and a call back to let me know all is good.
I am not only pleased to have a system that has proven reliability and substantial savings that were promised, but grateful for the diligent and excellent customer service that they provide. I strongly recommend Big Dog Solar to anyone considering such a system.
