The Enphase" M215 Microinverter with integrated ground delivers increased energy harvest and
reduces design and installation complexity with its all-AC approach. With the advanced M215, the DC
circuit is isolated and insulated from ground, so no Ground Electrode Conductor (GEC) is required
for the microinverter. This further simplifies installation, enhances safety, and saves on labor and
materials costs.
The Enphase M215 integrates seamlessly with the Engage® Cable, the Envoy® Communications
Gateway`"', and Enlighten®, Enphase's monitoring and analysis software.
PRODUCTIVE SIMPLE RELIABLE
- Maximizes energy production - No GEC needed for microinverter - More than 1 million hours of testing
- Minimizes impact of shading, - No DC design or string calculation and millions of units shipped
dust, and debris required - Industry-leading warranty, up to 25
- No single point of system failure - Easy installation with Engage years

To: Town of Northampton
212 Main Street
Northampton, MA 01060
Subject: Structural Certification for Installation of Solar Panels
Leahan Residence
234 Spring Grove Road
Florence, MA.01062
To Whom It May Concern,
A design check for the subject residence was done on the existing roofing and framing systems for the installation of solar
panels over the roof. From a field inspection of the property,the existing roof support structures were observed by Direct
Energy Solar auditors as follows:
The roof structure of(Roof A)consists of composition shingle on roof plywood that is supported by fink trusses that are spaced
at @ 24"o.c..The trusses have a max projected horizontal span of approximately 26'-0"between exterior load bearing walls,
and a slope of 25 degrees.The top chords are 2x6 sections,the bottom chords are 2x6 sections and the web members are 2x4
sections.The truss members are connected by steel gusset plates.The max unsupported projected horizontal top chord span is
approximately 7'-0".
The existing roof framing system of(Roof A)is judged to be adequate to withstand the loading imposed by the installation of
the solar panels. No reinforcement is necessary.
The spacing of the solar standoffs should be kept at 48"o.c.with a staggered pattern to ensure proper distribution of loads.
I further certify that all applicable loads required by the codes and design criteria listed below were applied to the Unirac
Solarmount solar rail system and analyzed. Furthermore,the installation crews have been thoroughly trained to install the
solar panels based on the specific roof installation instructions developed by Unirac Solarmount for the racking system and
Ecofasten for the roof connections. Finally, I accept the certifications indicated by the solar panel manufacturer for the ability
of the panels to withstand high wind and snow loads.
Design Criteria:
• Applicable Codes= Massachusetts Residential Code,8th Edition,ASCE 7-05,and 2005 NDS
• Roof Dead Load=8 psf(Roof A)
• Roof Live Load=20 psf
• Wind Speed=90 mph, Exposure B
• Ground Snow Load=40 psf - Roof Snow Load=28 psf
Please contact me with any further questions or concerns regarding this project.
Sincerely, a`rg4Jo
