Advantages and Disadvantages of Solar Photovoltaic System


Advantages and disadvantages of solar photovoltaic system

advantages

Solar energy is inexhaustible. The radiant energy received by the earth’s surface can meet the global energy demand of 10,000 times. Solar photovoltaic systems could be installed in just 4% of the world’s deserts, generating enough electricity to meet global demand. Solar power generation is safe and reliable and will not be affected by energy crisis or unstable fuel market.

2, solar energy can be everywhere, can be nearby power supply, do not need long distance transmission, to avoid the loss of long distance transmission lines;

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

4, solar power without moving parts, not easy to damage, simple maintenance, especially suitable for unattended use;

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

6. The construction cycle of solar power generation system is short, convenient and flexible, and the capacity of solar array can be arbitrarily added or reduced according to the increase or decrease of load, so as to avoid waste.

disadvantages

1. The ground application is intermittent and random, and the power generation is related to the climatic conditions. It cannot or rarely generate electricity at night or in rainy days;

2. Low energy density. Under standard conditions, the solar radiation received on the ground is 1000W/M^2. Large size use, need to occupy a larger area;

3. The price is still relatively expensive, 3-15 times that of conventional power generation, and the initial investment is high.
