High-power condenser and PV module technology continues to improve

High-power condenser reflection and transmission of the two practical HCPV power generation system condenser multiples of 500 × 1200 times the commercialization of high-power concentrating home solar panels photovoltaic power generation system efficiency from 23% to 28%. Fresnel lens is easy to design and simulation and lower costs, the main factors for concentrator photovoltaic systems using the lens. 

EmcoreConcentrix (SOITEC) Fresnel lens concentrator. However, to meet the requirements of high-power condenser system, to achieve long-term against environmental erosion, the Fresnel lens manufacturing also faces a series of challenges. There are a variety of technology manufacturing Fresnel lens, such as polymethylmethacrylate (PMMA) injection molding and hot pressing, and glass coated silicon gel (SOG), which require more complex fabrication process.

The transmittance, spot uniformity, focal length, process consistency, aberration, anti-UV, anti-sandstorm capacity assess the lens of the important indicators are.PMMA and SOG lens is now the most common of the two Fresnel lens. The high-power concentrating photovoltaic module contains a time lens, receiver, box and breathable device.

Single power module from tens of watts to watts range, depending on the system and tracker design the IEC62108 [Concentrator photovoltaic (HCPV) modules and assemblies-Design qualification and typeapproval] is only concentrating solar panels for sale receiver and groups pieces of international norms of evaluation criteria.

The U.S. Solfocus is one of the few manufacturers of reflective optical system used in the system design HCPV. The use of large parabolic mirror dish to do reflective optical system is considered to be a significant reduction in the the condenser manufacturing cost effective way, being in the combined heat and power (integrated PV + solar thermal) system.

Here to tell you about Canada MorganSolar. They developed a unique optical design (LightguideSolarOptic) is considered to be the major breakthrough of the CPV systems become much lighter and more thin photovoltaic modules in the same concentration magnification, greatly reduce the cost of module production while also reducing its tracker. Morgan's optical system can effectively reduce infrared radiation on the chip, so as to solve the heat problem.

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.

From a policy perspective, the concentrating cheap solar panels power technology in the government to promote the next in order to develop other photovoltaic technology.The European photovoltaic applications is done best in Germany, Spain, Italy and other European countries, the government give great efforts to feed-in tariff.

Favored relative to hydroelectric power, wind power, solar photovoltaic power generation due to less impact on the environment. HCPV relative to other photovoltaic technology, its enormous cost reduction potential to make it in a variety of new energy technology competition in advantage.
