I found energysage to be an extremely useful tool in not only my solar purchase, but also my understanding of the solar industry. It has great resources to help us learn about everything from inverters to panel warrantees. It also makes going solar so easy. In the past, I sat through a salesman telling me what he wanted me to know about his company and the solar system that they offer. With energy sage, I was able to see the entire picture of what was being offered and compare that to other quotes at the same time. I would not have gone solar without energy sage making this process so much more transparent and easy.
