What are the advantages and disadvantages of photovoltaic power generation ah?

Photovoltaic power generation is a renewable energy technology that uses light energy to convert solar radiation into electricity. It has the following advantages and disadvantages:

Advantages:

1. Renewable and Clean Energy: Photovoltaic power generation is a renewable source of energy, and solar radiation is virtually unlimited on Earth. Compared with traditional coal-fired or gas-fired power generation, photovoltaic power generation does not produce greenhouse gases and air pollutants, which is more friendly to the environment.

2. Quiet and low maintenance: PV power systems have no mechanical movement during operation and are therefore very quiet. Compared to coal-fired or gas-fired power plants, PV power systems have low maintenance costs, which mainly consist of regular cleaning and checking the condition of the modules.

3. Distributed Generation and Flexibility: PV power systems can be distributed in various places, including rooftops, solar farmland, deserts, etc.. This distributed layout reduces transmission losses and allows for flexible scaling to meet different power needs.

4. Long life and scalability: Solar modules have a long life, usually working for more than 25 years, and are scalable. The number of solar panels can be increased or decreased as needed to flexibly respond to changes in energy demand.

Disadvantages:

1. Affected by weather: The efficiency of photovoltaic power generation is affected by weather conditions, such as cloud cover, cloudy days and nights. In cloudy weather or at night, the capacity of PV power generation decreases.

2. Relatively low energy density: Compared to traditional fossil fuel-based power generation, PV has a lower energy density, meaning that a larger area is needed to get the same amount of power generated.

3. Limited resources and higher costs: The production of solar modules and other materials required for PV power generation is energy and resource intensive. Currently, the cost of manufacturing and installing solar cells is still relatively high, although costs are gradually declining as technological advances and economies of scale are realized.

4. Energy storage and network access challenges: Electricity generated by PV needs to be stored or connected to the grid. Energy storage technologies are not yet fully mature, and connecting to the grid may involve grid upgrades and transmission capacity constraints.

Photovoltaic power generation is affected by a variety of factors, including meteorology, equipment parameters, and installation conditions. Among them, all the parameters needed for power generation calculation can be provided by the Xihe-energy big data platform (xihe-energy.com).

In the platform, it is possible to simulate a preset PV power plant in a certain geographic location based on meteorological data, or restore the historical power generation curve of a certain PV power plant. By specifying the location, time, data source and PV plant parameters, an accurate hourly power curve is obtained.
