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 thejanuary 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.
Respectfully,
Adam Thurrell
Operations Manager

Re: Kajka Residence, Florence, MA
PV Squared Project No. 12100
NECE Project No. 18-001 T-145
Dear Ms.Geschwind,
At your request New England Construction Engineering, PLC(NECE) has reviewed the
information that Pioneer Valley PhotoVoltaics Cooperative, Inc. (PV Squared) provided on the
roof and supporting structure of the Kajka residence, at 40 Nutting Avenue in Florence(village
of Northampton), MA.The purpose of this review was to provide an opinion as to the
structure's ability to support a proposed rooftop mounted photovoltaic(PV)array.The
information that you provided is attached for reference.
You are proposing to erect PV panels on the south facing surface of the house roof.The house is
a two-story wood framed residence with a gable roof.The roof has a 23-degree pitch.The roof
is supported by manufactured wood fink trusses at 24"O.C.You have provided a second-floor
design plan and section and roof truss design output.These trusses span approximately 25'on
the horizontal.The roof trusses were designed for a ground snow load(Pg)of 50psf. The truss
top and bottom chords and webs are 2x4.The top chords are MSR Fb=2100psi grade SPF
lumber. The bottom chords are N2 SPF.The web members are Stud grade SPF.The roof plans
call for nominal 5/8" plywood roof deck.The roof has asphalt shingles.
NECE's analysis and review includes controlling gravity load combinations(snow and dead
loads). In providing this review we assume that the roof and supporting structure was
constructed as designed.We further assume that the trusses were properly installed with
diagonal bracing for out-of-plane forces.
Conclusion:
Based on the information that you provided, in my opinion,that the house roof will adequately
support the design snow load and the additional dead load of the PV array. 1 base this opinion
on the assumptions already discussed and the following additional assumptions. I assume that
New England Construction Engineering, PLC PV Squared—Kajka Residence
Jonathan Rugg, P.E. Florence, MA
Page 2 of 2
owing to their smooth surface,the PV panels will shed snow more readily than the existing
asphalt shingles. I also assume that PV panels will be installed parallel to the roof,eliminating
any additional wind load.The ground snow load (Pg)for Northampton is 40psf. According to
information that you have provided,the proposed PV panels weigh approximately 2.6 psf.
In summary, in my opinion,and predicated on the assumptions above,the house roof rakers
will support the proposed PV array.
Thank you for the opportunity to assist with this project. If we can be of further assistance,
please contact Jonathan Rugg at NECE.

POLICY DOCUMENT #9
Current version adopted by the Board of Directors on April 28, 2011
INSTALLATION CREW OPERATING POLICY
This policy applies to all PV Squared employees in Massachusetts, but is particularly
directed at those involved in the installation of solar electric and other renewable energy
systems (licensed electrician, learner/apprentice electrician, licensed constructor
supervisor, supervised carpenter and laborer).
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
Policy # 9
Installation Crew Operating Policy
Pioneer Valley Photovoltaics Cooperative
POLICY DOCUMENT N9
Current version adopted by the Board of Directors on April 28, 2011
• 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).
