One of the questions that is often asked by people in the photovoltaic industry or looking to buy solar energy systems is how many kilowatt-hours a year can a single photovoltaic panel produce? To answer this question, we first need to understand the factors that affect the power generation of solar panels:

First, the power generated by solar panels.
Second, the area where the solar panels are installed.
The more power the photovoltaic panels produce in the same area, the shorter the time it takes to produce one kilowatt-hour of electricity, and the more power they produce in a day.

Photovoltaic panels, with sunlight to generate electricity. So, there's no electricity at night. Similarly, the wind haze, rain and snow weather, it is almost impossible to send electricity. That is to say, photovoltaic power generation is closely related to the location of installation. Different resource areas, the same type of photovoltaic panels, will also produce different amounts of electricity. Some places have an inherent advantage because they are well lit.

On average, a single photovoltaic panel can produce about 400 (theoretical) kilowatt-hours of electricity a year.

Why is it theoretical? This is because, in addition to the power generation of photovoltaic panels, installation area (annual equivalent utilization hours), photovoltaic power generation is also subject to external factors, such as installation Angle and orientation, local climate, connection line material, surface shielding, etc.

The installation Angle and orientation of the photovoltaic panels are required so that the photovoltaic panels can fully receive the light and exert the maximum effect. If the random installation, people have an Angle, you lie down; When people sit in the south, you just sit in the north. If you deviate from science, it will affect the power generation.

Days of rain, snow, haze for a long time, sandstorms, and so on, even the sun can not see, no matter how good the photovoltaic panels can not generate electricity.

If you use poor quality cable and other lines, the electricity will be secretly lost, no matter how much power is sent, it is also easy to cause accidents. This shows the importance of material.

The shielding of photovoltaic panels should be cleaned frequently. For example, if there are trees or tall houses near the photovoltaic panels, the total light has not been for a few hours, how can we fully generate electricity? This is the problem of location. Or, in a windy and sandy place, you just have to install photovoltaic panels, but don't maintain them carefully. The panels are covered with dust and can't generate enough electricity.

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