From a field inspection of the property,the existing roof support structures were observed by Astrum Solar auditors as follows: The roof structure of(Roof A)consists of composition shingle on roof plywood that is supported by nominal 2x12 rafters @ 16"o.c., paired with nominal 2x10 raised ceiling joists @ 16"o.c..The rafters have a max projected horizontal span of 11'-0", with a slope of 35 degrees.The rafters are connected at the ridge to a continuous 2x12 ridge board and are supported at the eave by a load bearing wall.There are plywood gusset plates that connect the rafters of opposite roofs rogether near the ridge. The roof structure of(Roof B)consists of composition shingle on roof plywood that is supported by nominal 2x12 rafters @ 16"o.c., paired with nominal 2x10 ceiling joists @ 16"o.c..The rafters have a max projected horizontal span of 15'-0",with a slope of 35 degrees.The rafters are connected at the ridge to a continuous 2x12 ridge board and are supported at the eave by a load bearing wall. There are 2x6 collar ties @ 32"o.c.for structural stability. 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 existing roof framing system of(Roof B)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: o Applicable Codes=Massachusetts Residential Code,8th Edition,ASCE 7-05,and 2005 NDS ® Roof Dead Load=10 psf(Roof A) -- 10 psf(Roof B) ® Roof Live Load=20 psf ® Wind Speed=100 mph,Exposure C ® Ground Snow Load=50 psf - Roof Snow Load=35 psf 1.311 �"A R��tt( La,�"e'Uh A%,41 �II..F 1�1811:A4 Y'Rl,� - Monterrror Residence, North Andover 1 8955 Her-ikels Lane, 'Suite 508 Annapolis]Lin ct,ion, flolD 207 PHONE 1.800.903.6130 FAX 443.267.00 30 AST RU I L R" Please contact me with any further questions or concerns regarding this project.

The Enphase' 250 Microinverter delivers increased energy harvest and reduces design and installation complexity with its all-AC approach. With the M250, 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 M250 integrates seamlessly with the Engage® Cable, the Envoy' Communications Gateway'"', and Enlighten, Enphase's monitoring and analysis software. ommmimmmmiwmm�iu'Mmni ammo'�uuumm'muuuuuoomumuummmmuumaln�moom ''...
