"We recently had Mega Power Electric Inc install a solar system and panels. The President and provided excellent communication all the way through the process. He even met with us after installation to explain the almost incomprehensible PG&E bill. Although not the least expensive bid, his was competitive and I felt he was as interested in educating me about solar and the various types of panels and inverter systems as he was in selling a system. He demonstrated how the array of panels would meet our energy needs and as opposed to some of the other companies, wasn't selling us more than we needed. We are very satisfied with our solar system and I highly recommended Mega Power Electric Inc."

"Trevor was super helpful through the entire process, great team that got us a cheaper monthly electric bill. Would recommend."

"The reviews below me said it best: Ezra was fantastic! He was prompt, professional, and very informative. He explained to me each of the things he was doing, what he looked for in an audit, and what to expect. He also answered all of my questions about the kind of improvements that were worth it and those that were a waste of money. We were required to have an Energy Audit to sell our home and our realtor recommended Ezra from Landmark construction & energy crew. Lucky for us, Ezra found no recommendations and gave us a good "bill of health." What I like more is that if he does have recommendations, he doesn't perform any work himself, providing a truly unbiased opinion.  I fully plan on having Ezra perform an audit of our next home, whether it is required or not."

"Excellent service!!! Michael Kautz was the technician providing the service. Very professional and knowledge regarding the HVAC system at my residence and the residence of my Dad. Thank you for providing excellent services."
