Rose Ave., Oxnard, CA 93033 <br />Tel: 8054864700 <br />Subjects Static load test results for the following: <br />Madmum Frame Maximum Frame Load Equivalent Wind SpeedMounting System Length• (In.)WIdth, (In.)obs/ftz;(mph>* * <br />Rooffrac® 65 40 50 125 <br />TE5T SETUP (as shown In attached drawingdetail): Three modules, as specified above, were botted to 136 x1.5'*2.5" <br />Professional Solar Products (PSP) patented Roofrrace support rails using an assembly of 5/16' Stainless Steel (SS) bolts, <br />SS lock washersand proprietary PSP aluminum cmampsandinserts. The Roofrrac® support rail was attached to the PSP <br />Roofrrac® structural attachment device with 3/8 SS hardware at four attachment points- The setup was attached to 2"x6 <br />wooden rafters using 5/16" x 3-1/2- SS lag bolts. The altachment spans consisted of 48" nontto rear with structural <br />attachments spaced 72-on center. <br />TEST PROCEDURE (asshown in attached drawingdetali): The test set up wastop loaded to 50 lb/fti The setup remained <br />loaded for an approximate period of 30 minutes. The maximum deflection and any signs of permanent deformation were <br />recorded. The testsetup was then inverted and loaded to simulate the uplift condition. The test set up was re-loaded to 50 <br />lb/ft:. The setup remained loaded for an approximate period of 30 minutes. The maximum deflection and any signs of <br />permanent deformation were recorded. <br />TEST RESULTS: <br />The maximum top load deflection was recorded at 0.313", wlthno permanent deformation. <br />The maximum uplift deflection was recorded at 0.250: with no permanentdeformation. <br />This document certifies the Roomace mountingsystem used with the modules, as specified above, withstands a 50 lb/f@ <br />static pressure load, equivalent to a wind speed of approximately 125 mph'*. The mountingsystem performed as expected. <br />Sincerely, <br />James R.Mind, S.E. <br />Thb enalneering report verifies that Vinci & Ass©clates has provided indelandent observation for load tesUng as describedinthisreport The results of this <br />load testienect actual dellectionvalues and are generally accepted as theindustiystandard for testing module mounting systerna, Vinci & Ahsociates does <br />not eld check instanations or verify that the mounting systenn Is installed as described in this endneeringreport <br />TO assist the building Inspector in verifringthe authenticity of <br />silverrellectlve-RoofTrace- label, 23 shown, is placed on at <br />with ·Professional Solar Prod.
