Solar energy has the advantages of universality, harmlessness, large reserves and long service life.
(1) Universal: The sun shines on the earth, without geographical restrictions, whether on land or sea.
No matter mountains or islands, they are everywhere, which can be directly developed and utilized, and it is easy to collect, without mining and transportation.
(2) Harmless: the development and utilization of solar energy will not pollute the environment, and it is one of the cleanest energy sources.
(3) Huge: The annual solar radiation energy reaching the earth's surface is equivalent to about 13 trillion tons of coal, and its total amount is the largest energy that can be developed in the world today.
(4) Long-term: According to the estimation of the rate of nuclear energy generated by the sun, the storage of hydrogen is enough to last for tens of billions of years, and the life span of the earth is about billions of years. In this sense, it can be said that the energy of the sun is inexhaustible.
From the energy saving and emission reduction targets of various countries and the United Nations Special Report on Renewable Energy, it is a worldwide trend to realize a high proportion of renewable energy substitution by 2050, which will promote the development of China's solar photovoltaic power generation industry.
The total energy demand will reach 5 billion tons of standard coal by 2030 and 5.2 billion tons by 2050. Renewable energy accounts for 40% of the total energy demand in 2050, and renewable energy accounts for 60% of the electricity demand. The installed capacity of photovoltaic power generation may reach 1 billion KW. The strong support of national policies will promote the rapid and healthy development of China's solar photovoltaic power generation industry
