How many kilowatt-hours of electricity can a photovoltaic panel generate in a year?

Do you know or do you calculated?,How many kilowatt-hours of electricity can a photovoltaic panel generate in a year?

China has a vast territory and abundant solar energy resources. In addition to the macro events of the photovoltaic industry, back to the micro photovoltaic panels. If someone suddenly asks you, how many kilowatt-hours of electricity a photovoltaic panel can generate in a year? Many people will be stunned, yes, how much is it? This involves two determinants of photovoltaic power generation:

First, the power generated by 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 kilowatt-hour of electricity, and the higher the amount of electricity generated in a day.

Photovoltaic panels can generate electricity only when there is sunlight. Therefore, there is no electricity at night. In the same way, electricity can hardly be generated even in strong winds, haze, rain and snow. This means that photovoltaic power generation is closely related to the installation area. Different resource areas, the same type of photovoltaic panels, will also produce different electricity. In some places, there is plenty of light, which is inherently dominant.

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 (yearly equivalent utilization hours), photovoltaic power generation is also subject to external factors, such as installation angle and orientation, local climate, Connection line material, surface obstruction, etc.

The installation of photovoltaic panels requires installation angle and orientation, so that the photovoltaic panels can fully receive the light and play the best role. If you install it indiscriminately, you have an angle, and you lie flat; if you sit north and face south, you just sit south and north, which is a departure from science, which will affect the power generation!

Days of rain, snowfall, long-term haze, sandstorms, etc., even the sun can’t be seen, and even the best photovoltaic panels can’t generate electricity.

If you use low-quality cables and other lines, the electricity generated will be secretly leaked. No matter how much it is, it will be useless, and accidents will easily occur. This shows the importance of material.

The obstructions of the photovoltaic panels should be cleaned from time to time. For example, if there are big trees or tall houses near the photovoltaic panels, how can you fully generate electricity? This is the problem of site selection. Or, the local area is very windy and sandy, and it is necessary to install photovoltaic panels, but without careful maintenance, the panels are covered with dust and cannot generate sufficient power.

All of the above are factors that affect photovoltaic power generation, so if you want to generate more power, you have to take care of it~
