The advantage and disadvantage of solar power.
Inexhaustible solar energy, the earth's surface solar radiation can meet the global energy demand of 10 thousand times. As long as solar photovoltaic systems are installed on the 4% deserts of the world, the electricity generated can meet the needs of the world.
Solar power generation is safe and reliable, and will not be affected by energy crisis or unstable fuel market.Solar energy everywhere, can be nearby power supply, do not need long-distance transmission, to avoid the loss of long distance transmission lines.
The solar energy does not use fuel, the operation cost is very low;
Solar power generation without moving parts, easy to use damage, simple maintenance, especially suitable for unattended use.
Solar power generation will not produce any waste, no pollution, noise and other public nuisance, no adverse impact on the environment, is an ideal clean energy;
The construction cycle of solar power generation system is short, convenient and flexible, and can add or reduce the capacity of solar array arbitrarily and avoid waste according to the increase or decrease of the load.
The ground applications are intermittent and random, and the generation capacity is related to climatic conditions. They can not generate electricity at night or rainy days.
The energy density is low. Under the standard conditions, the solar radiation intensity on the ground is 1000W/M^2. When the large size is used, it needs to take up a large area.
The initial investment is high.
