The solar tracker is used to keep the solar
panels at any time of the sun, so that the light of the sun at all vertical
exposure to solar panels power plant. The tracker is divided into two
kinds of single-axis tracker and dual-axis trackers.
Uniaxial type suitable for relatively low Si solar cell on tracking accuracy requirements or trough concentrating system, as applied to the roof of the system, its direction of development tends to be small and lightweight. Biaxial apply to high tracking accuracy requirements concentrator small solar panels power generation system, the tracking accuracy of up to 0.1 °, mainly used in large-scale power stations, to medium-sized, solid, high-aspect of development.
Solar tracker main sensor tracking, classification according to the tracking method to calculate the the sun trajectory tracking and hybrid tracking. Sensor tracking method using photoelectric sensors to detect the degree of deviation of the sunlight and the battery plate normal feedback tracking, the tracking accuracy of 0.1 °, but affected by the weather.
Sun trajectory tracking method is based on the actual trajectory of the sun at a predetermined program to adjust the tracking device and this tracking method can weather real-time tracking, the tracking accuracy of about 0.5 °. The hybrid combines the advantages of both, in good weather sensor tracking to ensure tracking accuracy; tracking method by sensor tracking to bad weather conditions, depending on the date of the trajectory tracking. According to statistics, HCPV system failure 90% from the tracker fails.
From a technical perspective, the main way to reduce the cost of photovoltaic cells 5: First, absorption through the full spectrum further improve the photoelectric conversion efficiency of the cell chip, the second is reused to reduce the chip manufacturing costs through the substrate, three, increase the system's condensermagnification and improve the optical efficiency of the entire assembly, are light and heat utilization, five is used to significantly reduce the cost of the condenser system.
From the market level, concentrating solar panel price photovoltaic technology to further mature and further expand the scale of production, its costs can be lower than the crystalline silicon and thin film batteries is expected within the next few years. To each kWh to 0.1 U.S. dollar, on the requirements of the installed system costs from $ 5 to 8 / watt down to $ 2 / W chip cost from 8 to 10 U.S. dollars / square cm to 3 to 5 USD / square centimeter. To achieve this goal, there is no certain industrial scale is not possible, which requires more corporate involvement.

Major development companies in the world from the chip HCPV power generation system of the whole industry chain vertical integration the U.S. Solfocus company, Amonix,
Highly considered the bigger and stronger the British Wotai from the industry has been committed to the technical threshold obliterated by high power concentrating solar panel manufacturers power technology in order to help more companies to successfully enter the industry. The company's main products are components of the receiver, the core components of the photovoltaic modules.
These receiver components for many enterprises do HCPV PV module development and system integration, paving the way into the HCPV industry.Meanwhile, we also do not have any experience in the design of enterprise PV module reference design to accelerate progress in the development of these enterprises.
