Re: Solar Panel Installation—As-built Certification
Anderson Residence
68 Higgins Crowell Road
West Yarmouth,MA 02673
Dear Sirs,
I've reviewed the as-built solar panel installation at this location to evaluate the existing roof
structure and the connection of the panels to the roof.
ri riia: Applicable codes: MA State Building Code—780 CMR,9th Edition
(2015 International Residential Code with MA Amendments)
2015 Wood Frame Construction Manual
Design roof load: 30psf live load, 10 psf dead load,40 psf total load
Design wind load: 140 mph,35 psi;Exposure Category
My findings are as follows.
1. The new solar panels will imply an additional dead load of 3 psf. The existing roof structure
(wood roof trusses @ 24"o.c.,with 2x4 chords and rafters(top chords),truss span=+/-28'-0")is
sufficient to bear this additional load. Inaccessible,assumed or concealed structural members that
were not documented during the initial site analysis will be verified by the system installer prior to the
system installation,and any discrepancies will be reported to the Architect in writing.
2. The solar panels are attached to the roof with the solar
as shown on the attached drawings. The mountingpanel mounting system,components and fasteners
are rated for 140 mph. system,roof connections and connection spacing
The as-built installation is in compliance with these specifications,building codes and all
manufacturers requirements and recommendations.
I therefore certify that the actual installation complies with the applicable codes and design loads
mentioned above and is acceptable for approval. Please let me know if you have any questions
on this information. Thanks!
Sincerely yours,
