Massachusetts

Licensing (General)
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.

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 (L x WxH).

A CSL is not required for solar PV installs as the Board of State Examiners of Electricians has ruled that all such PV install work requires a Massachusetts licensed electrician (an example of an exemption from the CSL is when a tradesperson, licensed by another state agency, is working under the umbrella of his/her trade license).

Licensing (PV)
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.

Interconnection with the electrical service requires the services of a licensed electrician and an electrical permit is required.

Electrical code: 2017 NEC Code and 2018 I-Codes

Reciprocity: Reciprocity with NH licensees only
