Rose Ave., Oxnard, CA 93033 <br />Tel: 805-4864700 <br />Subject:Static load test results for the following: <br />Maximum Frame Maximum Frame Load EqulvalentWInd SpeedMounting System Length* (In.)Width' (in.)(lbs/fF)(mph)** <br />Rooffrac ® 65 40 55 135 <br />TE5r SETUP (as shown in attached drawing detail): Three modules, as specified above, were bolted to 136"xl.5°xl.5" <br />Professional Solar Products (PSP) patented Roofrrac® support rails using an assembly of 5/16" Stainless Steel (SS) bolts, <br />SS lock washers and proprietary aluminum clamps and inserts. The Roofrrac® support rail was attached to the PSP Roofrrac® <br />structural attachment device with a 3/8" SS nut and SS washer at six attachment points. The setup was attached to 2"x6" <br />wooden rafters using 5/16" x 3-1/2" SS lag bolts. The attachment spans consisted of 48" front to rear with structural <br />attachments spaced 48"on center. <br />TEST PROCEDURE (as shown in attached drawing detail): The test set up was top loaded to 55 lb/fe. 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 test setup was then inverted and loaded to simulate the upiift condition. The test set up was re-loaded to 55 <br />lb/fe. The setup remained loaded for an approximate period of 30 minutes. The maximum deflection and any signiof . <br />permanent deformation were recorded. <br />TEST RESULTS: <br />The maximum top load deflection was recorded at 0.469", with no permanent deformation. <br />The maximum uplift deflection was recorded at 0.313", with no permanent deformation. <br />This document certifies the Roofrrac® mounting system used with modules, as specified above, withstands a 55 lb/fe static <br />pressure load, equivalent to a wind speed of approximately 135 mph'*. The mounting system performed as expected. <br />Sincerely, <br />James R. Vinci, S.E. <br />This engineering report verifies that Vinci & Associates has provided independent observation for load testing as described in this report. The results of this <br />load test reftect actual deflection values and are generally accepted as the industry standard for testing module mounting systems.
