Reviews
What customers say
Positive reviews praise helpful, professional planning and installation; one homeowner appreciated being offered the option to pay a little more to run conduit through the attic rather than outside on the roof, and another says Windfree and its electrical contractor quickly handled minor post-install issues. One customer reported absent project management, errors in engineering documents and very poor communication, as well as no fall protection on a 20-foot roof, an arcing incident that melted insulation on main feeder cables, and a failed inverter after five months; they said the service manager stopped responding until they escalated the issue to an executive. An earlier customer said the system took three months to start crediting their power bill, with poor communication and no priority given to completing the connection.
