PV inverter market undetermined shape quality, technology, inter-brand competition

With more to build more photovoltaic power plants, inverters manufacturers and production capacity is also increasing rapidly. Currently famous inverter manufacturers have over thirty, and large and small enterprises have been involved in more than one hundred. In the disorderly competition, the price has become the most direct means of competition. A number of large power stations in the western tender, has 500kW inverter manufacturers offer less than 0.5 yuan / watt. Built in 2011 in Qinghai many power plants, the inverter by the problems have been ignored.

Sun power, Corona and TBEA Xinjiang new energy, etc. are among the first companies involved in inverter, and the business started in the early wind power inverter. With the expansion of photovoltaic power plants, more and more manufacturers began to emerge inverter. Power to the sun for example, the former head of the production department factory founded after leaving Guanya power. GREAT sun power with the emergence of staff has a close relationship.

The Hefei University has become a Chinese inverter industry source technology can not be ignored. Sunshine Power General Manager Cao Renxian Hefei University was originally a teacher, founded in 1997, this is currently the largest in the domestic energy business after the inverter until today also serves as the university's doctoral tutor.

 Hefei University of the inverter technology has a relatively mature technology, and its inverter drawings also been sold in many companies, large and small, which was founded in 2000 in Anhui EHE New Energy technology is also aided by Hefei University. With inverter manufacturers and capacity gradually plump, Hefei University of inverter drawings prices are falling. Early on, a set of drawings of the selling price inverters up to 300 million yuan, now the price has dropped to four or five hundred thousand yuan.

Compared to the simple replication of existing technologies and improved many bought by "drawing" production inverter gridtiepowerinverteronline manufacturers, Chint Group, a subsidiary of Shanghai Chint Power Systems, Inc., and affiliated TBEA Xinjiang new energy is more Relying on the parent company in the electrical field of technology accumulation.

Kehua RXPE, KSTAR, Kyushu Electric, Zhuzhou CSR, broadcasting electrical, NARI, etc. are with the South since earlier in the power supply, electricity and other related businesses to get involved in the accumulation of the field of photovoltaic inverters. Nortel Energy is using a route Sino-US cooperation in technology and product quality on the breakthrough. This new factory is located in Qingdao, participants, and R & D institutions in California. IDS in energy-saving and Switzerland to cooperate in investment and construction in Tianjin inverter factory.
