When the homeowner got canvassed by a national solar company, he went to work researching local companies. His shortlist was three local companies and the canvassing company. We were not the lowest priced, (the national company was the highest by far) but we had the best value due to the X-21 Black 350 SunPower modules with inverters he wanted and the other companies could not get. He chose Yes to install the 8.4 kW system which offsets 11,661 kWh of electricity. The SunPower modules have the best efficiency rating and longest warranties, but have premium pricing. He was impressed by the whole Yes team and its dedication to quality and customer satisfaction, and even posted a testimonial on the SunPower website.
