It was very helpful to see the various quotes for residential solar installation on our home in a chart format. Aside from the quote chart, I was able to access solar panel and inverter reviews by clicking the equipment links within the quotes. Lastly, an Energy Sage staff person, Peter, was accessible by phone and provided additional information regarding the quotes, equipment, and whether including batteries was advisable. In all, energy sage made installing solar, a totally foreign process to us, a lot more understandable and less stressful. So, thank you..
