The Asymmetric Tracking Concentrator Photovoltaic Systems is a high-tech method used in the world's solar energy industry to significantly reduce the cost of the third generation of photovoltaic systems. It not only highlights the main advantages of contemporary silicon solar photovoltaic systems, photovoltaic systems can reduce the cost of electricity has ten times and then a big drop on the basis of one third of the cost. And on December 8, 2010 successfully obtained independent intellectual property patent in China. It reduces the cost of solar electricity generation by 1/3 to 1/6 of the similar products on the market.
Three aspects of the present invention patent is the core of the innovative technology to simplify the tracking and converging methods technically and scientifically:
First, two-dimensional automatic tracking system. It works according to the daily operation of the Sun system by using a normal micro-motor, a simple integrated circuit, and a reduction gear. The precise implementation makes sure that the two-dimensional angle and elevation angle of the Sun movements are automatically tracked even in harsh whether conditions. The photovoltaic module can be kept concentrating at the Sun all the time to produce the best photovoltaic power output for decades. The tracking itself consumes less than 0.5% of the electricity generated.
Second, the use of more scientific asymmetric condenser formula that considers the factors of the photovoltaic power plant location, the annual average temperature, and how to avoid PV modules being burned by over-heated
Third, replacing expensive stepper motors with regular motors and using newly invented designs of circuit controller. These helped to achieve a precise control of the motor rotation angle.
The most suitable product market prospects:
First, the construction of large photovoltaic power plant with a 20% less total cost than the flat fixed photovoltaic panel power plants.
Second, the construction of small-scale concentrating photovoltaic power plant on the roof of a building, can be used for a large number of roads electric vehicle charging stations; but can also supply a wide range of uses by hospitals, schools, military units, villas, offices, businesses. So it can be used as independent power supply or backup power supply.
Third, single power generators are suitable and affordable for families, the average generating capacity is about 4 degrees.
Fourth, the product demonstrates photovoltaic power generation, light converging, two-dimensional automatic Sun tracking, accompanied with the conversion from DC to AC, etc. the product of a small model can be widely used as scientific instrument and teaching equipment.
