"They simply did a great job. I had them remove the old insulation, install new batt insulation, and add radiant barrier in my attic. Now my attic and house are a whole lot cooler. It is noticeably cooler in the house. The person who contacted me was Dustin. He was very professional and did a great job explaining things to me and laying out my options. The crew, which included Aldo, Roman, and Aaron were very professional and respectful to the care of our home and performing their job. I would definitely recommend and am willing to rehire them again for possible future projects. Thanks guys."

"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."

"We purchased the home energy audit with the understanding that we would be receiving a more extensive analysis of our home energy usage along with possible solutions. Ultimately, the process was more about a presentation for solar panels that anything else, which was not what we were looking for when we purchased the offer. Richard was very professional and thorough in his presentation and presented options regarding areas to save in terms of energy usage but those areas were not as thoroughly explored as the solar discussion. Green Source Energy should be more direct about what the Home Energy Audit entails so buyers can make an informed decision."
