advantage
1) Reliable operation: It can supply power normally even under harsh environmental and climatic conditions.
2) Long lifespan: Crystalline silicon components typically have a lifespan of over 25 years, while amorphous silicon components typically have a lifespan of over 20 years.
3) Low maintenance costs: After completion, only a small number of staff are required to conduct regular inspections and maintenance on the system. In comparison, conventional power stations incur significant maintenance costs.
4) Natural energy: The energy source is inexhaustible solar energy, with no energy costs required.
5) No noise pollution: The entire system has no mechanical moving parts, thus generating no noise.
6) Modularity: Select system capacity according to needs, with flexible and convenient installation, and easy expansion.
7) Safety: There are no flammable materials in the system, ensuring high safety performance.
8) Autonomous power supply: It can operate off-grid, providing independent power supply and being unaffected by the public power grid.
9) Distributed power generation: Decentralized photovoltaic power stations can be constructed to reduce the impact and harm on the public power grid.
10) High Altitude Characteristics: In regions with high altitudes and strong sunlight, the output power of the system can be further increased. (Compared to photovoltaic power generation in high-altitude areas, due to lower air pressure, diesel generators experience reduced efficiency and output power.)
shortcoming
1) High initial investment costs: Due to the high initial investment, it is necessary to conduct economic evaluations of individual systems and compare multiple options. If the initial investment decreases and the cost of conventional fuel increases, the photovoltaic system will become more competitive.
2) Unstable sunlight: Weather has a significant impact on the power output of any solar energy system. When climate or site conditions change, the system design must also be adapted accordingly.
3) Energy storage device required (standalone system): During the night, the photovoltaic power generation system cannot generate electricity without sunlight. Therefore, it is necessary to add battery energy storage equipment, which increases the system scale, cost, and maintenance workload.
4) Efficiency needs improvement: From the perspective of investment effectiveness, it is required to utilize photovoltaic system resources efficiently. Users must use high-efficiency load devices.
5) Technical training is required: Photovoltaic systems utilize many new technologies that are unfamiliar to many people. Therefore, users need to undergo technical training before operating the photovoltaic system.
