1. Does the photovoltaic power generation system have noise hazards?
Photovoltaic power generation system converts solar energy into electric energy without noise impact. The noise index of the inverter is not higher than 65 decibels, and there is no noise hazard.
2. Does the photovoltaic power generation system have electromagnetic radiation hazards to users?
Photovoltaic power generation system converts solar energy into electrical energy based on the principle of photovoltaic effect generated by light. There is no pollution and no radiation. Electronic devices such as inverters and power distribution cabinets have passed the EMC (electromagnetic compatibility) test, so there is no harm to the human body.
3. How to deal with the temperature rise and ventilation problems of solar cells?
The output power of photovoltaic cells will decrease as the temperature rises. Ventilation and heat dissipation can improve the efficiency of power generation. The most commonly used method is natural wind ventilation.
4. What issues should be paid attention to in the fire protection and fire protection of household distributed photovoltaic power generation systems?
It is forbidden to stack flammable and explosive materials near the distributed power generation system. In the event of a fire, the loss of personnel and property is immeasurable. In addition to basic fire safety measures, the photovoltaic system is also reminded to have self-checking and fire protection functions to reduce the occurrence of fires. Possibly, in addition, it is necessary to reserve fire protection and maintenance channels every 40 meters long, and there must be an emergency DC system disconnect switch that is easy to operate.
