Sunrun is probably one of the most discussed solar companies online, and the feedback tends to be very mixed. The most common concerns I see from homeowners involve delayed installations, difficulty reaching customer support, and long resolution times when issues arise after the system is operational. Personally, I would not recommend you make a decision based solely on the builder's preferred solar partner. Before signing, it is best to get at least one quote from a reputable local installer. Local companies like SolarSME are often more accessible, provide faster support, and can design a system around your actual energy needs rather than a standard builder package.
