Interconnection will be a circuit breaker connection in the existing 200 Amp electrical panel located in the basement.Install a 35 Amp,2 pole Eaton BR Classified circuit breaker for the solar connection in the existing 200 Amp panel.The circuit STRING& breaker for the solar connection MUST be installed at the far end of the panel away from the main circuit breaker.From the solar circuit breaker,bring the conduit outside and wire into a 60 Amp non-fused disconnect switch mounted on the CONDUIT LAYOUT adjacent exterior wall.From the disconnect switch,wire through the PV meter and then into the PV combiner panel.From the PV combiner panel,bring the conduit back into the basement.Once in the basement,transition to interior conduit then run conduit across the basement ceiling to get over to the west end of the house.At the west end of the house penetrate outside then run exterior conduit up the wall,wrap up over the eave and bring onto the roof.Once on the roof,run exterior conduit across the roof to the two junction boxes located under the two arrays,as shown in the drawing. All roof mounted conduit must be at least 1"above the roof surface and flash supported properly.There will be two circuits of inverters to the roof.

The leveling feet will be fastened directly into the existing joists with 5/16" diameter lag screws with a minimum embedment of 2.5". In addition, it is important that the leveling feet support locations be staggered between adjacent panels so that no single rafter supports more load than under the existing conditions. Wind Loading: Based on our calculations,the net wind loads imposed on the roof framing with an attachment spacing as indicated above will be less than the current loading on the roof framing. In addition, provided that the leveling feet are attached to the roof framing members in atypical staggered fashion,the overall wind loading imposed on the structure and the individual framing members will not be impacted to any great extent. If you have any questions regarding this matter,please feel free to contact my office at 609-489-5511. We appreciate the opportunity to assist you with this evaluation.

From a practical standpoint,the International Residential Code allows up to 2 roof coverings on a residential dwelling. Each layer of roofing imposes a net load of about 2.5 to 3.0 PSF on the roof. From this perspective, since the existing roof has only a single layer of shingles,a second layer is allowed to be added by the code without analysis.This 2nd layer of shingles essentially weighs the same as the proposed solar panels. ➢ Materials such as metal roofs or solar panels are considered slippery surfaces. Since the solar panels are mounted slightly above the roof line, it would be conservative to consider a thermal factor Ct of I.1,treating the panel surface as a cold roof rather than a warm roof. Based on the roof slope and considering it as a slippery surface,the snow load is reduced by 27% compared with the snow loading directly on the existing shingled roof surface. This reduction equates to 5.97 PSF which essentially offsets the weight of the solar panels. N.. ■■■ ■■■u■' ■ ■uZ N.

Our analysis was based on the framing information and configurations provided by Direct Energy Solar. It is our understanding that the structural components of the existing roof framing are in fair condition. It is further understood that all existing connections between the various roof framing members, including ceiling joists and rafters are adequate to resist the current loading conditions and behave in the manner that a typical rafter and ceiling tie system is intended to behave prior to installation of the solar panels. Results Roof A—adequate to support the proposed solar panels Structural Data and Code Information Our analysis was performed in accordance with the requirements of the 780 CMR 51.00: Massachusetts Residential Code which has adopted the 2009 International Residential Code with Massachusetts amendments. Per Table R301.2 (1),the ground snow load to be used for each town is in accordance with Table R301.2(5). Similarly,the wind speed for each town is in accordance with Table R301.2(4). The roof framing was analyzed in accordance with Section R104.11 of the of the 2009 International Residential Code which allows for alternate approved design such as using the ASCE 7 code for determining actual snow loads on roofs(e.g. deriving flat or sloped roof snow loads from the specified ground snow load referenced in Table R301.2(5)). Wood members were analyzed and designed in accordance with the NDS 2005. The roof area for the solar panels of this residence is framed in a gable configuration with conventional 2x roof rafters. The existing roof structure is in good condition and is assumed to have one layer of asphalt MPP Engineers, LLC 1 34 South Main Street, Suite D I Allentown,NJ 08501 609-489-5511 (office) I www.mppenvineers.com 1 609-489-5916 (fax) City of Northampton 212 Main Street, Northampton, MA 01060 Solid Waste Disposal Affidavit In accordance of the provisions of MGL c 40, S54, I acknowledge that as a condition of the building permit all debris resulting from the construction activity governed by this Building Permit shall be disposed of in a properly licensed solid waste disposal facility, as defined by MGL c 111, S 150A.
