What are the weight ratings of standard roof mountings?
This question is a logical one, and an important one. Every home owner who wants roof top solar also wants a sound water proof roof. Some are interested in and want to ensure that both the building and the solar structures, and components meet the industry standard for strength and design. How is that done on the solar PV front?
There is no one undisputed compliance and certification code for structural components or equipment. The largest, and most successful manufacturer, QuickMount, has certified their product under the ICC-ES certificate backed by a PE stamp. Eco-fasten in association with IronRidge, have received an IAPMO – UES certificate. Both of these are nationally recognized by ANSI and SEA respectively. Both have received certified PE stamps on the testing and results conducted. The test completed include lateral, uplift, and rain test on the completed mounting bracket with L-foot, and installed Lag screw. The test results can be found on the products webpage, or the hyper-links attached to the brand names above. Additionally QuickMount stands by their product with a full 20 year warranty.
