What are the advantages and characteristics of solar power generation and why is it the future power generation trend?

I. Advantages of photovoltaic power generation

1, solar energy is inexhaustible, and the solar radiation energy received by the earth's surface can meet the global energy demand 10000 times. As long as solar photovoltaic systems are installed in 4% of the world's deserts, the electricity generated can meet the global demand. Solar power generation is safe and reliable, and will not be impacted by energy crisis or unstable fuel market;

2. Solar energy is available everywhere and can be supplied nearby without long-distance power transmission, thus avoiding the loss of long-distance power transmission lines;

3, solar energy does not need fuel, and the operating cost is very low;

4. Solar power generation has no moving parts, is not easy to be damaged and easy to maintain, and is especially suitable for unattended use;

5, solar power generation will not produce any waste, pollution, noise and other public hazards, no adverse impact on the environment, is an ideal clean energy;

6. The construction period of solar power generation system is short, convenient and flexible, and the capacity of solar array can be increased or decreased at will according to the increase or decrease of load to avoid waste.

Second, the shortcomings of photovoltaic power generation

1, ground application is intermittent and random, and power generation is related to climatic conditions, so it is impossible or rare to generate power at night or in rainy days;

2. Low energy density. Under standard conditions, the intensity of solar radiation received by the ground is 1000 W/m 2. When used in large specifications, it needs to occupy a large area;

Three, as far as the current photovoltaic industry is concerned, the main benefits of installation are:

1, national support projects, installation can apply for state subsidies.

Compared with two years ago, the cost of these years has been greatly reduced, and the current return on investment should be considerable. Judging from this trend of reducing costs, national and local subsidies may soon be gone.

3. Green energy projects are energy-saving and environmentally friendly, benefiting future generations, and are very suitable for old-age projects.

4, the state power company has a special window to accept, according to the development of other countries, because of the restrictions of grid connection.
