Photovoltaic certification is approved by the national certification bodies, such as TUV (Technical Inspection Association), the IEC (International Electrotechnical Commission), the China Quality Certification Center (CQC) on photovoltaic enterprise products meet compliance with the relevant standards of the certification. Photovoltaic product certification can be divided into two major categories: safety certification and performance certification. UL is the world's first engaged in photovoltaic product safety certification research of the third party testing agency. Solar photovoltaicSolar photovoltaic power generation has the advantages of being full of clean, relatively wide range, long life and maintenance free, which is considered as the most important new energy in twenty-first Century. Since 2002, the rapid development of solar photovoltaic industry in China, the output of solar cell in 2007 has been ranked first in the world. Photovoltaic products have what?Crystalline silicon photovoltaic modules; controller, inverter, control inverter integrated machine; independent photovoltaic system; thin film photovoltaic modules; grid connected inverter; photovoltaic battery; concentrating photovoltaic modules; photovoltaic system connector; junction box; solar photovoltaic wire; CABLES; backplane; bracket; photovoltaic glass; PV application products: DC lighting, solar lights, solar lawn lamp, garden lights, LED lights, and so on.
