Open Sky Energy designed and installed a system perfectly sized for our home. Michael was thorough in explaining our options and the installation team was efficient and clean. Highly recommend for anyone in the Philly suburbs.
David K.
We appreciated the straightforward approach — no upselling, just honest recommendations based on our energy usage. The system has been producing consistently for six months and our electric bills are nearly zero.
Jennifer B.
Good quality installation and responsive customer service. The only delay was on the utility side for interconnection, which Open Sky helped us navigate. Overall a positive experience.
