1、Does the photovoltaic power generation system have noise hazards?
Photovoltaic power generation system converts solar energy into electrical energy and does not produce noise. 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 is based on the principle of photovoltaic effect to convert solar energy into electricity, no pollution, no radiation, inverters, distribution cabinets and other electronic devices have passed EMC (electromagnetic compatibility) test, so there is no harm to human body.
3、How to deal with the temperature rise and ventilation 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, and the most common method is natural wind ventilation.
4、What should I pay attention to in terms of fire prevention and firefighting of distributed PV power generation system?
In addition to the basic fire safety measures, the PV system should be reminded to have self-detection and fire prevention function to reduce the possibility of fire, in addition to the need to reserve fire prevention and maintenance channels at intervals of up to 40 meters, and there must be an emergency DC system disconnect switch for easy operation.
5、The advantages of photovoltaic power generation
(1) Solar power generation without moving parts is not easy to damage and simple to maintain.
(2) Solar power generation process is not easy to produce pollution waste, is the ideal clean energy.
(3) Solar energy is available everywhere and does not have to be transported over long distances to avoid the loss of long-distance transmission lines.
(4) The construction period of solar power generation system is short, convenient and flexible, and solar arrays can be added or reduced at will according to the increase or decrease of load to avoid waste.
(5) Solar energy is inexhaustible, the earth's surface receives enough solar radiation energy, 10,000 times the current global energy demand, as long as the installation of solar energy in 4% of the world's deserts can meet global needs, safe and reliable, not subject to the impact of the energy crisis and fuel market instability.
