advantage
1) Stable operation: normal power supply even in harsh environmental and climatic conditions.
2), long life: the life of crystalline silicon components is usually more than 25 years, and the life of amorphous silicon components is usually more than 20 years.
3), low maintenance costs: only a small number of staff after completion, regular inspection and maintenance of the system, in comparison, conventional power station maintenance costs are very large.
4), natural energy: energy is inexhaustible, inexhaustible solar energy, no energy costs.
5), no noise pollution: the whole system has no mechanical moving parts, no noise.
6), modular: according to the need to choose the system capacity, flexible installation, convenient, easy to expand.
7), safety: no flammable items in the system, high safety performance.
8), independent power supply: can be off-grid operation, independent power supply, not affected by the public grid.
9) Distributed power generation: decentralized photovoltaic power stations can be built to reduce the impact and harm to the public power grid.
10), high altitude: in the area of high altitude and strong sunshine, it can increase the output power of the system. (Compared with photovoltaic power generation at high altitudes, due to low air pressure, the efficiency of diesel generators is reduced, and the output power is reduced.)
shortcoming
1) High initial investment cost: Due to the high initial investment, it is necessary to conduct economic evaluation of a single system and comparison of multiple schemes. If the initial investment is reduced and the cost of conventional fuels rises, the photovoltaic system will be more competitive.
2) Unstable sunshine: weather has a great impact on the power output of any solar system. When climate or site conditions change, the system design must also change.
3), need energy storage device (independent system) : photovoltaic power generation system at night, no sunlight can not generate electricity, need to increase battery energy storage equipment, thereby increasing the system scale, cost and maintenance workload.
4) Efficiency needs to be improved: starting from the effectiveness of investment, it requires the efficient use of photovoltaic system resources. Users must use efficient load equipment.
5), the need for technical training: photovoltaic systems use a lot of new technologies that people are not familiar with, so users need to go through technical training before running photovoltaic systems.
