The growth of the photovoltaic industry

Since the global oil crisis broke out in the 1970s, solar photovoltaic power generation technology has attracted great attention in western developed countries, and photovoltaic industry has developed rapidly in the world. The installed capacity of photovoltaic power generation increased gradually from 135.76GW in 2013 to 386.11GW in 2017 and then to 480.36GW in 2018. In a short period of five years, it has increased 3.5 times. The Asian market leads with 274.6GW of PV installed capacity.  In the future, the global photovoltaic industry will maintain a high level and enter the industry integration period.

Since three scientists in bell laboratory successfully developed monocrystalline silicon cell in 1950s, photovoltaic cell technology has been continuously improved and developed, and a set of complete and mature technology has been formed at present. With the implementation of the global sustainable development strategy, the technology has received strong support from many governments and is widely used in the world.  Since the global oil crisis broke out in 1970s, solar photovoltaic power generation technology has attracted great attention in western developed countries, and photovoltaic industry has developed rapidly in the world.

According to the latest data of the International Renewable Energy Agency (irena), the global installed capacity of photovoltaic grid-connected is 94.3gw in 2018, 171gw in 2018, more than half of the installed capacity of renewable energy is solar energy, and the cumulative installed capacity of photovoltaic grid-connected is about 1/3 of the global installed capacity of renewable energy. Photovoltaic power generation increased gradually from 135.76gw in 2013 to 386.11gw in 2017 and then to 480.36gw in 2018, achieving a 3.5-fold increase in just five years. The growth rate is amazing.
