All aspects of a PV installation are considered electrical work and must be done by a properly permitted and licensed electrician.  Mass building code and states that any electrical generating equipment and ancillary equipment must be installed by a licensed electrician.

A Construction supervisor’s license (either an unrestricted CSL or a restricted one and two family CSL) is required when solar thermal work is involved and the building is a one or two family, stand-alone dwelling or is a small commercial building (less than 35,000 feet of aggregate volume (LxWxH)

Building permits are required any time solar thermal or solar PV is placed on a roof or ground rack due to new roof loads and/or wind issues. Interconnection with the electrical service requires the services of a licensed electrician and an electrical permit is required.
