In the Solar Powered System,The Ballast Mounting Structure is specially designed as a flat roof mounting system for cement and metal sheet rooftops, with the unique west-eastern layout for the solar panels in order to get a better sun radiance on the solar panel. The structure so called High Durability Ballast Support Mounting can get a full sunshine in a whole day, with the result of increasing electrical power generated by solar system by over 15% than the traditional norther-southern layout. The structure can be widely accepted by most areas and most of the climates all over the world, with an excellent performance in the extreme weather by 60m/s wind load. The structure can decrease the total weight of the solar system on a building rooftop so that the total pressure on the rooftop can be reduced, which can make the whole building safe enough. The structure can achieve a fast installation job by 500KW per day with 2 human labors, which will be efficiently reduce the labor costs an…
