The Engineer Group, LLC 20 Bofat Hill Road Chesterfield.MA 01012 Date: 08-08.2016 To: Bill Killough-Hill, PV Squared, 311 Wells Street. Ste. II. Greenfield, MA 01301 Re/Pmject: 60 Lake St. Florence , MA roof gravity load analysis for addition of solar panels. Bill, Per your request,we have analyzed 2 roof sections the main roof,and the rear additoin,at the above referenced address for gravity loads to asses the addition of solar panels to the existing structure. After the site visit on 8/05/2016,we ran some calculations on the roof with 4 psf elicited for solar panel dead loading in addition to snow and existing dead load. The rear addition is 2x6 rafters at 16"o.c. spanning appx. 9',and we find no reinforcement of this area is required.The main roof made from 2x6 rafters at 16"o.c. are spanning appx. 12',and we reccommend reinforcement for this roof.A drawig of the roof is attached. The following describes the loading used for our calculations,and assumptions/conditions made for the panel installation. Loading Analysis: According to the Massachusetts State Residential code, the standard for snow load in the area of the home is 40 psf ground snow load. The following factors were also used; occupancy category II, 1 =1.0,et=1.2,C=1.0,Pg=40 psf,and Pf= 30.8 psf. Although the code and references allow load reduction for balanced snow condition loading,reductions for pitch, and slick roof surface, it requires an unbalanced snow condition be analyzed for each side of the roof as well.The Residential code references ASCE7-05 as a standard to calculate snow loading, which allows roof rafters to be evaluated using the ground snow load, as the unbalanced load condition.The unbalanced load of 40 psf on the solar panel side is the controling case for the roof in question. We propose a retrofit to the main roof by installing 2x4 kneewalls according to the attached sketch. We estimate the dead load of the roof to be 14 psf with the solar panels, rafters, and existing asphalt shingle, which includes an additional 4psf for the solar system.The calculations were based on SPF#2 material,even though the materials in the existing rafters may exceed the stress values of todays SPF. With the absence of visible grade stamps on the existing material, we feel this is a conservative approach. Solar Panel /Racking Conditions/Assumptions: The solar panels are to be mounted on an aluminum rail system with the rails installed parallel to the ridge, and approx 42" o.c. max spacing between rails. Rails to have support foot spacng of 48" o.c. maximum along each rail, and one support at each end. Closer spacing is allowed for rails or supports. Supports are to be fastened through the sheathing into the rafter member without splitting or stripping the fastener.Any stripped fasteners,or fasteners that miss or split the rafter are to be repositioned. Split rafters shall be repaired in an approved manner. Each row of rail supports must be staggered with the adjacent rail supports by 16"or to the adjacent rafter to distribute the load over all the rafters as uniformly as possible. The panels, rail system/suports must be rated by the rail I panel system manufacturers for the support spacings above for the indicated ground snow load. Fastening of the rails/support system to the rafters is to Page I of 2 The Engineer Group, LLC 20 Bofat Hill Road Chesterfield. MA 01012 he done for 90 mph, 3 sec gust wind, pressure, and uplift in addition to the indicated snow load, Design of solar panels, rails, supports. and their respsective fasteners is by others and not addressed by this analysis. Retrofit Required: Please see the attached sketsh for the main roof retrofit. No retrofit is required for the rear roof. Items not included in this report: Typically,the panel/rail/suppon system, and fastening methods for the same are designed by the manufacturers of these components or their engineers. Therefore, the following is not included in our review at this time, and not covered by this report.These items may be required to complete the solar system install requirements.We have not performed a full wind analysis on the rafters, as this is typically uncommon for existing buildings in this wind zone/building location, and verification can not be made for the hidden fastening of components. Given the age of the building, the wind resistance is not likeley to pose an issue for the raters.If you require design or review for any of these items,we can provide them in addition to this report. We believe this proposal is conservative given the good condition, and age of the structure. This proposal is not to be considered final,and construction should not begin until it has both the engineers seal,and the final approval from the building department having local jurisdiction. If you have any questions, please give me a call.
