Our analysis was based on the framing information and configurations provided by NRG Solar.It is our understanding that the structural components of the existing roof framing are in good condition. It is further understood that all existing connections between the various roof framing members behave in the manner that a typical truss system is intended to behave prior to installation of the solar panels. Results House Rear&Garage Rear Roofs—NOT adequate to support the proposed solar panels • Provide sistering/reinforcement with new 2x4 member for all top chords on the side where solar panels will be installed.Reinforcement shall be the full length of the top chord and be installed flushed with the ridge and extended down towards the eve. • Attach all reinforcements using(2)SDS 1/4"x 3"long screws @ 12"O.C. or(2) 16D common nails @ 6" O.C.for full length of member. • If the reinforcement for the top chord cannot be installed as a single piece,it may be installed as two separate pieces provided there is a minimum 4 feet of lap. Rear Dormer South Roof—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 8301.2(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 8301.2(4). The MPP Engineers,LLC 1 34 South Main Street, Suite D I Allentown,NJ 08501 609-489-5511(office) 609-489-5916(fax) Derby Residence Solar Installation 531 Johnson Street North Andover,MA 01845 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 areas for the solar panels of this residence are framed in a gable configuration utilizing pre- engineered metal plate connected wood trusses.All roofs have the same configuration, as per information provided by NRG. The existing roof structure is in good condition and has one layer of asphalt shingles. The pertinent data is listed below: House Rear,Garage Rear,&Rear Dormer South Roofs(40 Panels Total): Roof Truss Members: 2"x 4"(#2 Spruce-Pine Fir Assumed) Spacing: 24"O.C. Roof Slope: 22 Degrees Horizontal Projected Length of Rafter (Horizontal Projection): 14.60 feet maximum Ceiling Joists: Present Roof Sheathing: Plywood Sheathing Condition of Framing: Good Roof Covering: Asphalt Shingles Ground Snow Load,Pg: 50 PSF from Table R301.2(5)of Massachusetts Residential Code Importance Factor,I: 1.0 Exposure Factor,Ce: 1.0(Conservatively taken as Partially Exposed) Thermal Factor,Ct: 1.1 with Panels(Cold Roof) 1.0 existing condition (Warm Roof) Design Snow Loads On sloped roof: 35.00 PSF(Existing—Unobstructed Warm Roof) 30.80 PSF(New—Slippery Surface on Cold Roof) Wind Speed: 100 MPH from Table R301.2 (4)of Massachusetts Residential Code Exposure B Analysis Results: General Considerations ➢ The proposed solar panels consist of solar panels which impose a total weight of approximately 2.5 to 3 pounds per square foot(PSF)on the roof surface. 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 2°a layer of shingles essentially weighs the same as the proposed solar panels. Derby Residence Solar Installation 531 Johnson Street North Andover,MA 01845 ➢ 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 1.1,treating the panel surface as a cold roof rather than as a warm roof, Based on the roof slope and considering it as a slippery surface,the snow load is reduced by 12%compared with the snow load acting directly on the existing shingled roof surface.This reduction equates to approximately 4.20 PSF which completely offsets the weight of the solar panels. Gravity Loading: House Rear&Garage Rear Roofs—NOT adequate to support the proposed solar panels • Provide sistering/reinforcement with new 2x4 member for all top chords on the side where solar panels will be installed.Reinforcement shall be the full length of the top chord and be installed flushed with the ridge and extended down towards the eve. • Attach all reinforcements using(2)SDS %4"x 3"long screws @ 12"O.C. or(2) 16D common nails @ 6"O.C.for full length of member. • If the reinforcement for the top chord cannot be installed as a single piece,it may be installed as two separate pieces provided there is a minimum 4 feet of lap. Rear Dormer South Roof—adequate to support the proposed solar panels It is our understanding that the panels will be installed using IronRidge rail with L-feet(or equal)at approximately 48 inches on center(e.g. every two to three rafters).The leveling feet will be fastened directly into the existing joists with 5/16"diameter lag screws with a minimum embedment of 3". 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 a typical staggered fashion,the overall wind loading imposed on the structure and the individual framing members will not be impacted to any great extent.
