China has a vast territory and rich solar energy resources. In addition to the macro events of the photovoltaic industry, go back to the micro solar panels. If someone suddenly asks you, how many kwh can a solar 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 of solar panels.
Second, the installation area of solar panels.
In the same area, the higher the power generated by solar panels, the shorter the time it takes to generate 1 KWH electricity, and the higher the power generation in a day.
Solar panels can generate electricity only when there is sunlight. So it can’t generate electricity at night. Similarly, electricity can hardly be generated in strong winds, haze, rain and snow. That is to say, photovoltaic power generation is closely related to the installation area. Different resource areas and solar panels of the same model will also produce different electricity. In some places, there is sufficient light, which is congenital.
If we have to calculate an average value, a solar panel can generate almost 400 kWh (theoretical value) a year.
Why theoretical value? This is because, in addition to the power generation and installation area of solar panels, photovoltaic power generation is also restricted by external factors, such as installation angle and orientation, local climate, connection line material, surface shelter, etc.
It is necessary to find the correct installation angle and orientation for the installation of solar panels, so as to make the solar panels fully receive the light and play the greatest role. If it is not installed correctly, the power generation will be affected!
Days of rain and snow, long-term fog and haze, sandstorms and so on, even the sun can not be seen, and no matter how good the solar panel can not generate electricity.
If lines such as inferior cables are used, the electricity generated is secretly leaked. No matter how much it is, it is useless and prone to accidents. This shows the importance of materials.
The shelter of solar panels should be cleaned from time to time. For example, there are big trees or tall houses near solar panels. The total light hasn’t been for a few hours. How can solar panels fully generate electricity? This is the problem of location. Or, due to the strong wind and sand in the local area, solar panels don’t have careful maintenance, the panels are covered with dust and can not fully generate electricity.
The above are all factors affecting photovoltaic power generation, so if you want to generate more power, you have to pay attention to the maintenance and care of solar panels.
