Sandbox Solar installed a 12 kW system on our Fort Collins home along with two Tesla Powerwalls. The owners Ian and Andrew were personally involved and answered every question. Production has exceeded estimates by about 8%.

We chose Sandbox because they are local and highly recommended by neighbors. The installation was quick and professional. They also installed an EV charger at the same time, which was super convenient.

Good company with quality equipment. The system is performing well. Only reason for 4 stars is that the timeline slipped by about three weeks due to permitting delays, but Sandbox communicated clearly throughout.
