I'm offering SIG and Josh Clark 5 stars due to the rapid response, efficiency, and quality of their service and install.
More details of my experience below.
I had been thinking about adding solar, and a backup battery, to my Cold Springs cabin for awhile. Last summer a friend suggested SIG due to his good experience. I called the main office on June 10th, and less than 1/2 hr later I received a call from Josh. We thoroughly discussed my needs and requirements. My questions, that Josh wasn't sure about, were answered within a timely manner. After a bit of banter about the number of panels required I received an estimate that fit my budget.
Exactly 1 month after 1st contact my system was installed in less than 7 hrs. Another 16 days passed and then the system was operational.
