Parabolic concentrator glass solar system

[China] DONGGUAN CITY HESOLAR CO., LTD

Description of The Key Technology

Independently developed high-accuracy solar tracking system: the solar target-seeking head is a combined application of light reflection principle, optical system and controlling software. It is able to adapt to the different types of weather, with a tracking accuracy of 0.05 degree. This invention was patented.

Independently developed low-cost long-life turning system:  It makes use of the miniature brushless DC machine, small spur gear box, and the adjustable clearance of turbine turning device, with a high cost-performance ratio.

Independently developed high reflection and high accuracy parabolic mirror: It uses the low iron supper white bending strengthening the silver impregnation  tempered glass and back curved tempered glass(or FRP) to make laminated out objectives. It is able to resist the ice storm, debris impact, and silver layer in sandwich. It has a long life, it is highly reflective, and it is easy to be cleaned. Equivalent glass cuts the silicon solar cells by about 96 percent. As a result, it could strongly reduce the cost of electricity generated from solar skills, and make the cost similar to the cost of electricity generated from coal.

Cooperated developed 30-times condenser silicon solar cells (encryption buried gate, back contact). Packing development of strip concentrator silicon solar cells module, the solar cell's conversion efficiency about 20%.The system of conversion efficiency can be reached 15% top.

Independent development design test system of gross structure: The poem said"Where once they visited great homes, dip among doorways of the poor is our noble vision--ptimization of power , light area,load rate of raw materials, structure volume, costs,   comprehensive factors such as the cost.It aims to make the solar light , electricity, heat and easy to popularize ,in order to make the user creative value and effiectiveness(the system has been got the country's patent )
