Power solar
modules are issued by the DC , the exchange must be changed by DC , to access
the grid or load . Photovoltaic solar inverter system is essential for the
device , the proportion of the cost of the PV system from about 10 % to 13 %.
Domestic PV
installed capacity market , mainly from the large-scale photovoltaic
demonstration power plant and the " Golden Sun Demonstration Project"
Energy Board. In 2010, the National Energy Board set up the second batch of
tender plants total size of 280MW, a total of 13 projects. Golden Sun
Demonstration Project for critical equipment ( PV modules , inverters and
storage batteries ) by winning 50% of the agreed price to give subsidies, other
costs according to different project types respectively 4 yuan / watt and 6
yuan / watt given a fixed subsidy . This projection, Golden Sun Demonstration
Project power plant construction costs about 7-8 yuan / watt, from 2010 to 2011
the recoverable cost of investment. Under the Golden Sun Demonstration Project
, the domestic photovoltaic power plant has a certain degree of profitability,
high market enthusiasm.
In addition,
December 2, 2010 , four departments jointly announced the aid of financial
subsidies , "Solar Roofs " program and other initiatives, strongly
promote large-scale application of photovoltaic power generation in the country
, and strive to complete the new installed capacity of 1000MW in 2012 ,
ensuring the realization of 2020 the total installed capacity of 20GW target
year .
For domestic
manufacturers , the PV inverter production only to Infineon , Semikron,
Mitsubishi, Fuji
and other international giants supplier core components to be assembled after
purchase . Eliminating the need for complex and expensive production equipment,
fixed investment is small , the industry barriers to entry are not high . The
next 1 to 2 years, as competition intensifies , with excellent technical skills
and a higher cost of corporate control will ultimately come to the fore .
PV inverter
power inverter and can be divided into small power inverter, power inverter
technology threshold is much higher than the small power inverter. At present,
the domestic manufacturers more entrants in the field of small and medium power
inverter , its technology has been at the same level with foreign manufacturers
. Small power inverter products produced alienation smaller , product stability
, cost, and delivery is a major manufacturer in the field of competition .
Overseas
business delivery is generally 6 to 8 months, domestic enterprises have
geographical advantages , relatively short delivery time . Meanwhile , domestic
enterprises capacity building fast , relatively low labor costs, has obvious
competitive advantage in the small power inverter. Power inverter (300KV, 500KV
, etc. ) due to the higher power , presents a greater challenge to stability .
Future competition in PV inverter technology , mainly in the field of high
-power inverter .
Start the
domestic PV market installed , so go the golden period of development of
domestic photovoltaic inverter . The short term, lead through quality
certification company has first-mover advantage. However, the PV inverter
industry is relatively low barriers to entry , after profits, cost and
technical advantages of long-term development of enterprises is fundamental .
