"Excellent experience. We had a connectivity problem with our solar panels. They responded quickly and set up an appointment right away and came when they said they would. The technician very personable. He was able to determine the problem and correct it, updated the software on our system, and explained that maintenance was not necessary. I would highly recommend this company."

"In order to get my roof repaired, I had to get my solar panels taken down and replaced. Bright Light Energy Corp got the job done for $400 less than my original quote and began work the day after I contacted them. The first company had a 30-day wait. They are clearly professionals who know their business and provide a well-done service in the time and cost they quote. I highly recommend this company."

"Kevin was great! The rest of the company not so much. Kevin diagnosed the problem immediately as the thermostat, had a replacement in the truck, and completed the installation of the new unit quickly. He showed me how to program the updated version, and everything seemed to be fine - until the next morning. Turned out the replacement was defective. When I called, I was told that they might not be able to get back to me that day, but Kevin interrupted his schedule to come back and put in a new (and working) unit at no charge."
