What are the requirements for the surrounding environment for rooftop photovoltaic power generation system installation?
There are large dust pollution sources around the photovoltaic power generation system, heavy sand, heavy smoke, etc., which affect the use of sunlight, which will lead to a decline in power generation.

Does the photovoltaic power generation system need to be disconnected during thunderstorms?
Distributed photovoltaic power generation systems are equipped with lightning protection devices, so there is no need to disconnect them. It is recommended that for safety insurance, you can choose to disconnect the circuit breaker switch of the combiner box and cut off the circuit connection with the photovoltaic module to avoid the harm caused by direct lightning that cannot be removed by the lightning protection module. The operation and maintenance personnel should check the performance of the lightning protection module in time to avoid the harm caused by the failure of the lightning protection module.

How to prevent lightning from photovoltaic power generation combined with buildings?
Lightning is mainly divided into two hazards: direct lightning strikes and indirect lightning strikes. Protection of direct lightning strikes: Set up metal lightning protection wires to the ground on tall buildings to release the huge charges of thunderstorm clouds.
Inductive lightning protection: Add lightning protection devices to the photovoltaic system, that is, add lightning protection modules to electrical equipment such as combiner boxes and inverters to protect against indirect lightning strikes.

When it is cold in winter, will there be insufficient power?
The power generation of photovoltaic systems is indeed affected by temperature, but the impact is very small. The factors that directly affect the power generation are the radiation intensity and sunlight, and the operating temperature of the solar cell components. In winter, the temperature is relatively low and the duration of sunshine will be short, so generally the power generation will be less than in summer, which is also normal.
Will the photovoltaic power generation system still work in continuous rainy or hazy days after installation? Photovoltaic cell modules can also generate electricity under a certain amount of low light. Haze does have an impact on photovoltaic power generation, but the impact on power generation efficiency does not exceed 5% (except for heavy haze). Under normal circumstances, the power generation in rainy days is only about 10%-20% of normal. Due to continuous rainy or haze weather, the solar radiation illuminance is low, if the working voltage of the photovoltaic system does not reach the starting voltage of the inverter, the system will not work, and the grid-connected power generation system and the distribution network are operated in parallel , When the photovoltaic system cannot meet the load demand and does not work, the electricity from the grid will automatically be replenished, and there is no problem of power shortage and power failure.

Will the photovoltaic modules be damaged if it encounters harsh environments such as hail?
First of all, according to the hail test results in the product description, it can be seen that the photovoltaic modules can withstand hail impacts with a speed of 44m/s and a diameter of 35mm at the best speed. The compressive performance of the module has passed the state of working in other harsh environments. Certified by an international professional organization. Secondly, we generally recommend that the owner find a regular insurance company to insure the solar power station. As long as the insurance is purchased, it will be compensated accordingly when encountering natural disasters.
