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 region, the higher the power generated by photovoltaic panels, the shorter the time it takes to generate 1 kilowatt hour of electricity, and the higher the power generated within a day.


    Photovoltaic panels, with sunlight to generate electricity. So, no electricity at night. Similarly, the wind fog and fog, rain and snow weather, almost no 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 produce different electricity. There are places where light is plentiful and nature has an advantage.




On average, a photovoltaic panel produces about 400 degrees of electricity a year.




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




To install the photovoltaic panels, the installation Angle and orientation are required, so that the photovoltaic panels can fully receive the light and give full play to their functions. If the installation, people have Angle, you lay flat; Somebody else sits north face south, you sit south face north unluckily, depart from with science, can not affect generation capacity!




Days of rain and snow, long periods of smog, dust storms and so on, even the sun can not be seen, no matter how good the photovoltaic panels can not power.




If use the line of inferior cable and so on, the electricity that send is missed secretly, send again much also trashy, still appear easily accident. This shows the importance of materials.




Solar panel shielding should be cleaned from time to time. For example, there is a big tree near the photovoltaic panel, or a tall house, the total light has not a few hours, how to fully generate electricity ah. So that's the location problem. Or, the local wind and sand, only to install photovoltaic panels, but not careful maintenance, the battery board is dusty, also can not fully generate electricity.
