Micro-inverter is now an important component of PV plants , micro-inverter to the panel level to achieve maximum power point tracking , central inverter has advantages beyond . So that each module can be achieved by optimizing the output power , the overall maximum output power . Now, with the steady growth of the global PV installed capacity , the industry that in 2017 the market will quadruple.
Before 2005, the mere presence of new energy industry in the laboratory and academic journals , from business applications within the foreseeable future , the government projects are almost no direct subsidies , venture capital is only several hundred million dollars annually . Today, the rising demand for energy and environmental pressures , prompting the world have invested in new energy development and a lot of effort . Now governments subsidies to further promote the development of new energy .
United States each year to provide new energy industry subsidies amounted to $ 90 billion , equivalent to 50 years of tax exemption to these companies . In contrast, the traditional energy industry only received $ 4 billion in subsidies. The photovoltaic feed-in tariff , for example, in Europe and
North America 's
leading solar energy are clearly defined national solar feed-in tariff policies
to encourage solar power technology research and development , project
development and wide application .
At the same time , the total installed capacity of solar energy rising relevance for many industries, such as polycrystalline silicon, micro- inverters have a positive impact , includingmicro-inverter output value of the industry is expected to quadruple in 2017 .
IEA PV installed capacity is expected to reach 230GW by 2017 according to the International Energy Agency (IEA) latest trends in the renewable energy market analysis and forecast in 2017 , the photovoltaic industry is expected to achieve strong growth .
IEA projections , the cumulative installed capacity of the grid from 2011 to
the 70GW 91GW, 2013 years of 115GW, 2014 years of 140GW, 2015 years of 167GW
and 197GW in 2016 and 2017 of 230GW. The IEA also said that with the increase
in installed capacity , the annual average level of PV capacity will reach 35
terawatt hour (TWh).
In all of the available solar wind inverter energy technology, the fastest growth rate forecast photovoltaic . The IEA said that , from the overall perspective, to 2017 , including concentrating solar power (CSP) , including solar power renewable energy will account for 4.9% of the total .
