Kuntz Residential Solar Project GreenSpark installed a 5.5kW solar array at the Kuntz residence in January of 2014. The solar array combined with the 10kW wind turbine that SunCommon installed years ago have allowed the family to cover 100% of their electric load with renewable energy. Your home could be powered by the sun. Our solar advisors can help you find the right solar solution for your home based on your electricity usage and affordability. We've helped countless homeowners in the Greater Rochester area make the switch to clean, local, and sustainable solar power.
