For photovoltaic power plants, every extra kilowatt-hour of electricity generated will increase the income of one kilowatt-hour of electricity. Many people think that the power generation of photovoltaic power plants of the same scale should be the same, but in fact, there are many determinants.
1. Light and environmental impact of the area
Photovoltaic power plants rely on the radiation of sunlight to generate electricity. The greater the intensity of solar radiation, the higher the power generation of photovoltaic power plants.
Statistics show that more than 2/3 of the regions in my country have more than 2,000 hours of sunshine per year, which is rich in solar energy resources. Depending on the latitude and the amount of solar radiation, the power generation of photovoltaic power plants is determined.
In addition to differences in solar energy resources, humidity and temperature in various regions will affect the power generation of photovoltaic power plants. In particular, particulate matter in air pollution, that is, smog, will reduce the efficiency of photovoltaic power generation, and the magnitude can even reach more than 17%. According to calculations, in smoggy cities, the power generation of photovoltaic power plants is obviously low. Moreover, when the smog is severe, photovoltaic power plants cannot even generate electricity.
2. Quality factors of photovoltaic power plants
Environmental problems are difficult to change, but a high-quality photovoltaic power station will definitely generate more power than a low-quality power station. From silicon materials to components, and from components to inverters, all devices play a decisive role in power generation.
Photovoltaic module quality
As the core component of photovoltaic power plants, the quality of photovoltaic modules plays a decisive role in the power generation of the power plant. The quality of photovoltaic modules is ultimately linked to service life and efficiency. First of all, the photoelectric conversion efficiency of photovoltaic modules represents the power generation capacity of the modules, so the higher the efficiency of the modules, the higher the power generation of the power station.
In addition to efficiency, the quality of photovoltaic modules is more reflected in anti-attenuation, anti-aging and other aspects. Inferior photovoltaic modules are prone to problems such as cracks and backplane aging. Once such problems occur, the efficiency of photovoltaic modules will drop significantly, resulting in low power generation of the power station.
Photovoltaic power station inverter quality
The inverter is as important as the brain and heart of the entire photovoltaic power station. Simply put, it can convert direct current into alternating current that can be connected to the grid. . With the development of technology, the current inverter has more functions, combining intelligence and big data to monitor the real-time power generation status of photovoltaic power plants, timely warning, and improve the efficiency through data analysis, intelligent deployment and other technologies. Power generation of photovoltaic power plants.
Speaking of which, the components, inverters, distribution boxes, brackets, cables, etc. of Skyworth photovoltaic power plants are all selected from well-known manufacturers, with strict and precise construction and installation, and international supervision standards, to provide users with all-round Create a high-quality high-quality power station to maximize the power generation of the power station.
3. Post-operation and maintenance of photovoltaic power plants to effectively increase power generation
In the 25-year or even longer service life of the power station, good operation and maintenance is the guarantee of power generation.
Providing real-time online system monitoring, timely response to fault reports, system cleaning and maintenance and other operation and maintenance guarantees for the power station can greatly affect the service life of the power station. Without good operation and maintenance management, it will be difficult to detect and solve equipment failures in photovoltaic power plants in a timely manner. The current smart photovoltaic system has the function of fault detection. If there is an abnormality in the photovoltaic power station, it will give an early warning and remind the operation and maintenance personnel to solve the problem. This can effectively reduce losses and increase the power generation of the power station.
In addition, it is also a very important point. Many power station users do not understand the operating principle of photovoltaic power stations. They use it as a board for drying things, such as drying quilts, shoes, dried food, peppers... This will block the components and affect the conversion of solar energy into current. , say small is to reduce the power generation income, say big even have the danger of destroying components.
