My experience with Certasun was extremely positive. They are very knowledgeable and well organized in the solar market. They broke down all the steps of the process and were very communicative along the way. The technicians and electricians were very efficient and polite. The installation process was quick and they provided a large team to ensure that. I was very impressed with the whole process and am very pleased with the solar results I'm achieving today.

Even after the installation, they have been helpful in addressing any follow-up questions. Overall, I highly recommend them to anyone considering solar—truly a company that values custome... read more
