Gardner Energy installed 12 panels on our house a few years ago. We were so pleased with their work that we hired them again this past year to add an additional 30 panels. Once again we found Gardner to be competitive in its bid, accessible and clear in their communications with us, honest about the timeline, and professional in their workmanship. The panels look great and the system works well. We definitely recommend Gardner Energy to anyone who is interested in installing a solar panel system.
