A field inspection was conducted upon the completion of installation and the following is a summary of my findings. The solar panels add approximately 4 psf to the existing roof structures. The standoff attachments are staggered as specified in the structural analysis. The products that were used in this project, such as the PV panels, racking systems, and accessories are consistent with these on the permit plan sheets. The installation crews have been thoroughly trained to install the solar panels based on the specific roof installation instructions developed by Unirac for the racking system, and by EcoFasten for the roof connections. I further certify that all applicable loads required by IRC 2009 with Massachusetts amendments were applied to the Unirac SolarMount rail system and analyzed. Finally, I accept the certifications indicated by the solar panel manufacturer for the ability of the panels to withstand high wind and snow loads. If I may be of further assistance, please not hesitate to contact me at my office at 978-406-8921. Sincerely, Elaine A. Huang, P.E.

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: • 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 SEE A SUNNY DAY IN A WHOLE NEW WAY® Montemor Residence, North Andover 1 ,ASTRUIMSOLAR` Please contact me with any further questions or concerns regarding this project.

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: • 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 SEE A SUNNY DAY IN A WHOLE NEW WAYO Montemor Residence, North Andover 1 ASTRU'MSOLAR Please contact me with any further questions or concerns regarding this project.
