U.S. companies set up the world's first hybrid photovoltaic/solar thermal panel cooling system. Chromasun, a rooftop solar company in the Silicon Valley of Meiyuan, announced in mid-December 2011 that it had installed the world’s first solar technology, a hybrid photovoltaic panel-coupled solar thermal cooling system, as shown in Figure 1.

The project was deployed in September 2011 in San Jose, California.
This project pioneered the use of newly developed Chromasun hybrid photovoltaic panels and solar cooling systems. By harnessing the sun's energy to generate electricity, and then using waste heat to drive an absorption chiller, the Chromasun system can provide more useful energy to buildings than previous methods, which is particularly useful for large-scale power and cooling load facilities. .
Traditional solar photovoltaic panels can only harvest 15% of the solar energy, while the new hybrid technology can harvest more than 75%.
Steel Structure Building is fabricated with steel for internal support and external cladding. Steel Structures are best suited for multi-storey buildings and used in high rise buildings, industrial buildings, hospitals, schools, malls, warehouse, and garage. Steel Structure buildings have been widely recognized, due to cost efficiency, improved safety and resistance. The usage of steel structures has expanded with improved materials, productions and design capabilities.
