Solar modules DC electricity is issued,
must pass DC to AC only after the grid or load. Photovoltaic inverter solar
power system is essential devices in the PV system costs accounted for about
10% to 13%.
Since China
Domestic PV installed capacity market,
mainly from the Bureau of Energy and large-scale PV demonstration power plant
"Golden Sun demonstration project". In 2010, the National Energy
Board set up the second batch of the total size of the tender plant 280MW, a
total of 13 items. Golden Sun demonstration projects on key equipment (PV
modules, inverters and storage batteries) bid price agreement by giving 50%
subsidy, 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 cost of approximately $ 7-8 / W,
from 2010 to 2011 recoverable investment costs. Golden Sun demonstration
project, the domestic photovoltaic power plant has a certain degree of
profitability, market enthusiasm is high.
In addition, 2 December 2010, four
departments jointly announced with financial subsidies, "Solar Roofs"
program and other initiatives, a strong push in the domestic large-scale
photovoltaic power generation applications, and strive to be completed in 2012
1000MW installed capacity was added, to ensure the achievement 2020 The
cumulative installed capacity of 20GW target.
For domestic firms, the production of photovoltaic
inverter is only to Infineon, Semikron, Mitsubishi, Fuji
PV inverter power inverter and can be
divided into small power inverter, power inverter technology threshold is much
higher than small power inverter. At present, the domestic manufacturers were
more likely to enter 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 small, product stability, cost, and
delivery is a major area of competition
manufacturers.
Overseas enterprises delivery is generally
6 to 8 months, the domestic enterprises have geographical advantages, the
delivery is relatively short. Meanwhile, domestic enterprises capacity building
fast, relatively low labor costs, in the small power inverter has an obvious
competitive advantage. Power Inverter (300KV, 500KV, etc.) due to higher power,
presents great challenges for stability. Future PV inverter technology
competition mainly in the field of high power inverters.
Domestic PV installed capacity market
launch, make homemade photovoltaic inverter into the golden period of
development. Short term, lead through quality certification company has
first-mover advantage. But PV inverter industry is relatively low barriers to
entry, profits after the cost and technical advantages of long-term development
of enterprises is fundamental. Recommendations concern listed companies
shortlisted Golden Sun demonstration project Kstar and XJ Electric.
A solar section scheme is one of the many types of little scale, dwelling power output systems which are available for dwelling users. Solar section schemes are adept to convert power from the lightweightweight of the sun into power, which can then be utilised to power the dwelling. In the Northern Hemisphere, solar section schemes usually work best when they are put in a southerly facing direction, as this is the direction which will get the most sunlight, and therefore they should be able to alter the highest amount of sunlight likely into power. Solar panel systems can be used on their own in some places where there is a bigger mean amount of sunlight, or as a supplement to fossil fuel energy in other locations.
