Keystone Energy uses multiple sources to purchase solar modules both domestic and abroad. We are also capable of installing footed panels for a standard residential roof, a non-penetrating ballasted system for a flat roof as well as ground mounted systems. Each design is site specific and custom built based on the particular application.
We would like to thank Keystone Energy for the fine planning and construction of our sunroom. The crews were on time and very nice. We had to force them to stop working and eat something! Everything you stated would happen, did!! You can add our name to your satisfied Sunroom Customer list. Thanks for everything!!!
