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 and total solar system costs. The Ballast mounting system requires a easily reachable base at the local site with a cement block weighted by 30Kg each ballasting on the top of each bottom rail, no need to think about complicated installing job for the base. As the total structure is made of aluminum alloyed AL6005-T5 and SUS304 materials, the structure is light and can be easily transported and delivered to any project sites, at the same time, the aluminum alloyed AL6005-T5 and SUS304 materials can make the whole structure have a wonderful performance in the total solar system for over 25 yearsBallet Roof Support Mounting and our other product combinations include: Energy Optimiser Maximum Input Power 800W,3rd Generation Of Micro Inverter, We can complete a complete Solar Powered System.
