Domestic Inverter, Converter Gradually to the Market

Release time：2011-04-01

        The overall goal of the power generation is to promote the optimization of the power supply structure and to adapt to the development of clean energy through in-depth research and application of network coordination technology, wind power and solar power grid-connected technology and large-capacity energy storage technology. 2015 to meet the needs of 60 million kW wind power and 5 million kW of solar power generation; 2020 to meet 100 million kW wind power and 18 million kW of solar power generation needs. Power generation links include the coordination of conventional power supply network, wind power grid, solar power grid and large capacity energy storage and other key links. Compared with the conventional power supply, most of the new energy power generation mode provides significant intermittent and random volatility, when the grid is large, it will affect the safe and stable operation of the power grid. As a useful addition to new energy power generation, energy storage technology can smooth the random and intermittent power output by storing power and play an important role in large-scale new energy generation and networking. Therefore, we believe that the grid technology and energy storage technology is particularly important. Below we will introduce the three key technologies in grid-connected technology - photovoltaic inverters, wind turbines and large-capacity energy storage.

      PV inverter: gradually enter the overseas market

          Inverter is one of the important equipment for solar photovoltaic power generation, the cost of about 10-20%. With the rapid growth of global installed capacity of the PV, the inverter market is also expanding. According to IMS Research, the global inverter market reached $ 2.9 billion in 2009, an increase of 14.8% and shipments of 8.3 GW. Global inverter shipments in the second quarter of 2010 were 4.9 GW, an increase of 284% year on year, but sales revenue increased by only 165% year-on-year due to the 30% drop in inverter prices. The first half of 2010, the global inverter shipments reached 8GW, an increase of nearly 3 times. According to Isuppli's forecast, the global inverter installed capacity from the 2.6 million units in 2010 to 23.3 million units in 2014, an increase of nearly 9 times. Sales revenue will grow from $ 5.3 billion in 2010 to $ 8.9 billion in 2014, with a compound annual growth rate of about 13.84%

          According to the "new energy industry revitalization plan" by 2020 China's photovoltaic installed capacity will reach 20GW. We estimate that by 2020 our country's domestic inverter cumulative market size of about 36 billion yuan, the next 10 years compound annual growth rate of about 46.3%. In 2008, Spain is the world's leading PV inverter consumer countries, accounting for about 45% of global consumption, followed by Germany accounted for 27% of total consumption.                       Accounting for more than 70% of the total global consumption, the global PV inverter consumption of regional concentration is very high. Its market development has benefited from the government subsidy policy for photovoltaic power generation. At present, the global PV inverter main enterprises are SMA, KACO, Fronius, Ingeteam, Siemens, Studer, Xantrex, Danfoss, Conergy, Satcon, Power-one, Outback power. SMA accounted for more than 40% of the global PV inverter market share, the world's second-ranked Kaco market share was 30%, only two leading enterprises market share of more than 70%. Many domestic enterprises or technical reserves, or have begun mass production, we expect them to be expected to obtain technological breakthroughs, fully benefit from the rapid growth of the inverter market. Domestic production inverter manufacturers have Hefei sunshine (specializing in the production of off-grid / grid-connected photovoltaic and wind power inverter), Beijing Suoying (feedback power and inverter), Beijing Kono Albert (system integration and inverter ), Zhicheng champion (UPS-based), Beijing good (small power-based), Nanjing crown Asia (control inverter main) and other enterprises. At present, the domestic photovoltaic inverter is mainly sunshine power, Ai Sima, KACO and other brands occupied by foreign enterprises through the majority of agents through the channel to enter the domestic market, due to the difficulty of providing a large overall market share is not high overall market share 2008 statistics show that Hefei Sunshine Power Company accounted for more than 70% of the PV inverter market share, the domestic focus of photovoltaic projects are almost all high-power products selected domestic products.
