How much electricity can a photovoltaic panel generate in a year? Probably many people will be stunned, yes, how much?
This involves two determinants of photovoltaic power generation:
First, the power generation of photovoltaic panels.
Second, the installation area of photovoltaic panels.
In the same area, the higher the power generation of photovoltaic panels, the shorter the time it takes to generate 1 kWh of electricity, and the higher the power generation in one day.
Photovoltaic panels can generate electricity only when there is sunlight. Therefore, the electricity cannot be generated at night. Similarly, in strong winds, smog, rain and snow, it is almost impossible to generate electricity. That is to say, photovoltaic power generation is closely related to the installation area. Different resource areas, the same type of photovoltaic panels, will also generate different amounts of electricity. In some places, there is enough light, which is inherently advantageous.
Calculating an average value, a photovoltaic panel can generate almost 400 degrees (theoretical value) of electricity a year.
Why is it a theoretical value? This is because, in addition to the power generation of photovoltaic panels and the installation area (annual equivalent utilization hours), photovoltaic power generation is also restricted by external factors, such as installation angle and orientation, local climate, connection line material, and surface shading. things etc.
The installation angle and orientation of photovoltaic panels need to be installed so that the photovoltaic panels can fully receive sunlight and play the best role. If you install it indiscriminately, people have an angle, you lay it flat; others sit north to south, but you sit south to north, which is contrary to science, but it will affect the power generation!
It rains and snows for days, haze persists for a long time, sandstorms appear, etc. Even the sun cannot be seen, and even the best photovoltaic panels cannot generate electricity.
If you use low-quality cables and other lines, the electricity generated will be secretly missed, no matter how much you send, it will be useless, and accidents will easily occur. This shows the importance of material.
The shielding of photovoltaic panels should be cleaned from time to time. For example, if there is a big tree near the photovoltaic panel, or a tall house, and the total light is not enough for a few hours, how can it fully generate electricity. That's a question of location. Or, the local wind and sand are heavy, and they only care about installing photovoltaic panels, but without careful maintenance, the panels are covered with dust and cannot fully generate electricity.
