Photovoltaics - The development and production
Photovoltaics - The development and production:
H photovoltaic energy production is a technology that directly converts light energy into electrical energy using the photovoltaic effect of the semiconductor interface. It mainly consists of solar panels (components), εreaders and converters, and the main components consist of electronic components. After solar cells are connected in series, they can be packaged and protected to form a large-area solar cell module, and then combined with power controllers and other components to form a photovoltaic power generation device.
In 2011, the new installed capacity photovoltaic in the world was about 27,5 GW, an increase of 52% compared to 18,1 GW in the previous year, and the global cumulative installed capacity exceeded 67 GW. Of the total installed capacity of almost 28 GW in the world, almost 20 GW of systems are being installed in Europe, but the growth rate is relatively slow The Italian and German markets account for 55% of the global installed capacity increase, 7,6 GW and 7,5 GW respectively. In 2011, the PV industry market demand in the Asia Pacific region represented by China, Japan and India increased by 129% year-on-year and its installed capacity was 2,2 GW, 1,1 GW and 350 MW respectively. Additionally, in the increasingly mature North American market, newly installed capacity is approximately 2,1 GW, an increase of 84%.
