Since July 29, under the influence of typhoon "Du Suri", Beijing has experienced the strongest rainfall since the beginning of this year's flood season, and the Beijing Meteorological Observatory has issued a regional rainstorm red warning signal.
Faced with such extreme weather, does the use of household distributed photovoltaic have any impact?
Today, I will summarize the following knowledge about the use of household distributed photovoltaic in thunderstorm weather.
Ask: Can exposed photovoltaic panels withstand the "watering" of rainwater?
Answer: The rain-proof and moisture-proof performance of regular photovoltaic panels is guaranteed.
Q: Do I need to turn off the PV system when it thunders?
Answer: The photovoltaic panel is equipped with a lightning protection combiner box, so it is not necessary to turn off the photovoltaic power generation system in case of thunder.
Ask: Will the photovoltaic system leak electricity when it meets water?
Answer: When installing photovoltaic panels, professional technicians will take grounding measures according to industry standards. The whole photovoltaic power generation system is an insulator, and there is no leakage problem.
Q : What should I do in case of power failure?
Answer: In case of power failure and tripping, manual closing is required to ensure the normal operation of photovoltaic. In order to ensure safe operation, relevant professional and technical personnel should be invited to operate.
Question: Can photovoltaic power generation system resist hail?
Answer: The qualified photovoltaic modules produced by regular manufacturers have the certificate of qualified solar energy products certified by China Quality Certification Center. Hail will not harm the qualified photovoltaic power generation system.
The front must pass a maximum static load (wind load, snow load) of 5400 pa. The maximum static load (wind load) on the back is 2400pa and the hail with a diameter of 25mm hits at a speed of 23m/s.
Q: Will PV still generate electricity in rainy days?
Answer: PV can generate electricity in rainy days, but compared with sunny days, the power generation of the system will be "discounted".
Finally, in thunderstorm weather, please do not touch outdoors without permission. If you find special circumstances, you should call the after-sales operation and maintenance telephone at the first time and contact professional technicians to solve them!
