Dear Town Inspections Officials, Please see our enclosed applications to permit a Solar Photovoltaic System in your jurisdiction. As you are likely aware, PV Squared is a worker-owned-cooperative B-Corp, employing 40+ people in Greenfield. We have installed thousands of PV Systems out of our Greenfield, MA Headquarters since 2002. PV Squared is committed to complying with all Commonwealth laws and regulations. Our worksite guidelines are created with the intention of exceeding all safety, electrical, and building requirements as defined by their respective jurisdictional entities. This includes the work of people from multiple disciplines, including electrical engineering, structural engineering, civil engineering, electricians, construction supervisors, roofers, and their associated helpers. We are a company that values training and education. We make certain that every individual is qualified for the roles and responsibilities that they assume. It is our policy to pay for the employees travel and training time and cost of the education, including CSL and Journeyman and Master Electrician classes. As an electrical contractor we are furthermore guided by the January 30, 2009 Massachusetts Board of State Examiners of Electricians (BSEE) judgements, and rulings that have followed. We pay strict adherence to these mandates and all electrical work is conducted by an electrician and an electrician’s apprentice in a 1:1 ratio. We also understand that non-electrical tasks associated with a Solar installation can be completed by non-electrical workers, such as CSLs and others. I have attached our installation policy for your review, as well as a list of example non-electrical tasks. Should you have any questions or concerns regarding this policy or delineation of work, please let us know. We are a learning organization that is always trying to improve on what we do.

(PV Squared) provided on the Barr & Mereschuk residence, at 69 Barrett Street, in Northampton, MA. The purpose of this review was to provide an opinion regarding the structure's ability to support a proposed rooftop mounted photovoltaic (PV) array. The information that you provided is attached to this letter for reference. You are proposing to mount PV panels on the south face of the house and the attached garage. The house is a one‐story ranch. The house measures approximately 25’x42’. The house has a gable roof which is symmetric about the peak. The roof has a 25‐degree pitch. The roof is supported by 2x6 rafters at 16” O.C. Ceiling joist resist the outward end reaction of the rafters on the walls. The roof has solid board sheathing and asphalt shingles. The attached garage measures approximately 24’x24’. The roof has a 22‐degree pitch. The roof is framed with site‐built trusses at 16” O.C. These trusses have 2x6 top chords, 2x4 bottom chords, and 2x4 web members in a fink truss configuration. The members are connected with plywood gussets. The roof has solid board sheathing and asphalt shingles. NECE’s review analysis included controlling gravity load combinations (snow and dead load). Lateral loads (wind and seismic) are excluded from this review and report. Consideration of snow loads included both balanced and unbalanced conditions. Conclusion: Based on the information that you provided, I conclude that the house and garage roof will support your proposed PV array. I base this opinion on the following. I assume that the PV panels will be installed parallel to the roof, eliminating any additional wind load. Owing to their New England Construction Engineering, PLC PV Squared – Barr & Mereschuk Jonathan Rugg, P.E. Northampton, MA Page 2 of 2 smooth surface, the PV panels will shed snow more readily than the existing asphalt roofing. The ground snow load (Pg) for Northampton is 40psf. The minimum flat roof snow load (Pf) is also 35psf. The information that you provided indicates that the proposed panels weigh 2.2psf. In summary, in my opinion, the roof will support your proposed PV array. Thank you for the opportunity to assist with this project. If I can be of further assistance, please contact Jonathan Rugg at NECE. Sincerely, Jonathan Rugg, P.E. New England Construction Engineering, PLC.

When engaged in this work as an employee of PV Squared on a PV Squared project site, activities of PV Squared employees are covered under the General Liability Insurance maintained by the Cooperative. It is the intent of this policy to provide clarity to installation situations where the applicable codes and regulations are unclear, ambiguous, or silent. It is possible that a municipal building or electrical inspector could interpret the codes and regulations in a manner that differs from what appears here. But this policy sets out, in writing, how the cooperative interprets legal work requirements and unclear details. It is an internal consensus working model, intended to be revised and improved from time to time. As a general matter, a city’s or town’s Building Commissioner is charged with enforcing the State Building Code, Plumbing and Gas Code, Electrical Code and Architectural Access Code. The commissioner addresses concerns about the safety, accessibility and security of construction of homes and businesses. The commissioner also enforces zoning bylaws. In accordance with Massachusetts General Law, employees of the cooperative who perform electrical tasks and activities must hold a Massachusetts journeymen’s electrician license or be under the direct supervision of such licensed personnel. These tasks and activities include installing electrical wiring, conduits, apparatus, devices, fixtures or other appliances for carrying or using the electricity associated with Renewable Energy Generators (electrically active solar photovoltaic modules, wind turbine-generators, hydroelectric generators, etc.). In no circumstances shall the Massachusetts licensed journeymen have more than one learner or apprentice working with him/her or under his/her supervision. Mounting structures come in a variety of configurations and have differing functional and physical characteristics.A structural component or assembly becomes associated with electrical work as the Renewable Energy Generator is electrically bonded to the mounting structure. Unless otherwise noted in M.G.L. c.143 §§3 through §§60 inclusive, all structural work defined as follows shall not be required to be performed by a Massachusetts licensed journeymen electrician: Structural improvements Elements of a Renewable Energy Generator’s support structure that fall under a building permit (e.g., assembly of top-of-pole mounting structure on steel pole with concrete foundation prior to execution of any required electrical bonding of the support structure and associated renewable energy generator (solar electric module) to the support structure Pioneer Valley PhotoVoltaics Cooperative POLICY DOCUMENT #9 Current version adopted by the Board of Directors on April 28, 2011 Policy # 9 Installation Crew Operating Policy Roof-top mounting support structures including but not limited to posts, stand-offs, flashings, feet, and mounting rails Operation of heavy equipment involved in moving, hoisting, digging and other tasks Earth work, excavation and concrete work Manual labor involved in moving loading and unloading of equipment Moving, hoisting, and attaching an electrically bonded panel assembly (defined as one or more assembled and electrically bonded solar electric modules) to an existing structural support designed to host the panel assembly. Note however that construction of a panel assembly is an electrical task due to the required electrical bonding activities. Repair and Servicing of Installed Equipment Repair or replacement of an electrically bonded and/or energized renewable energy generator (e.g., installed solar electric panel) will be performed by a licensed electrician or properly supervised learner or apprentice working with the licensed electrician. Replacement of an installed inverter must be performed by a licensed electrician or properly supervised learner or apprentice working with the licensed electrician, if the work requires removal of AC and/or DC conduit and associated wiring that originates outside of the installed inverter (e.g., removal of external AC conduit and wiring between the inverter and point of interconnection with the on-site electrical service). Note that this activity may require a wiring permit in some local jurisdictions. This requirement also applies to the servicing of an installed inverter that involves replacement or repair of components and wiring internal to the pre-manufacturer inverter (i.e., factory installed components that were originally shipped with the inverter) even though such activity may not require a wiring permit. Replacement of an installed inverter may also be performed by a qualified technician who may or may not be a licensed electrician or properly supervised learner or apprentice working with a licensed electrician if the inverter is of a “plug and play” design. Such a qualified technician can also performed other tasks that include installation and servicing inverter-based performance monitoring systems (e.g., replacing internal communication cards, making “plug and play” ethernet connections, etc.), assuming these activities do not require creation of a new AC power source circuit to operate the communication system(s).
