1. The higher the temperature, the more electricity it generates?
Answer: The normal temperature of a photovoltaic module is 25 degrees. If it does not rise by one degree, the power will drop by 0.04%. The main factor affecting photovoltaic power generation is not temperature, but the duration of sunlight.
2. If photovoltaics have already been installed, why do you still need to pay electricity bills?
Answer: Photovoltaics can only generate electricity when there is light. At night, photovoltaics cannot generate electricity. If you need electricity at night, you need to use the mains power supply, and you need to pay for this part of the electricity, which is the grid-connected system.
However, if you do not want to pay electricity bills, you need to add batteries to the photovoltaic system. During the day, the remaining electricity is stored in the battery for use at night.
3. What should I do if the photovoltaic power generation decreases?
Answer: If you are a layperson, first check whether there are any buildings, trees or other obstructions nearby. Secondly, check whether there is dust or bird droppings on the surface of the photovoltaic panels. Clean the surface of the photovoltaic panels regularly. Finally, check whether there is any damage on the photovoltaic panels.
If you are an industry insider, in addition to the above three points, you should also check whether the connections between the photovoltaic panel components are firm and whether the connecting wires are damaged.
