1. Is there any noise hazard in the photovoltaic system?
Photovoltaic system converts solar energy into electrical 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 system have electromagnetic radiation hazards to users?
Photovoltaic system converts solar energy into electrical energy according to the principle of photovoltaic effect generated by light. It is pollution-free and radiation-free. 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 of solar cells?
The output power of photovoltaic cells will decrease as the temperature rises. Ventilation and heat dissipation can improve the power generation efficiency. The most commonly used method is natural wind ventilation.
4. What problems should be paid attention to in the fire prevention and fire protection of household distributed photovoltaic power generation system?
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 specially reminded that it has self-detection and fire prevention functions to reduce the occurrence of fires. In addition, fire and maintenance passages must be reserved at intervals of up to 40 meters, and there must be easy-to-operate emergency DC system disconnect switches.
5. Advantages of photovoltaic system
1) Solar system has no moving parts, which is not easy to be damaged and easy to maintain.
2) It is not easy to produce polluting waste in the process of solar system, which is an ideal clean energy.
3) Solar energy can be obtained everywhere, without long-distance transportation, avoiding the loss of long-distance transmission lines.
4) The solar system has a short construction period, is convenient and flexible, and can add or reduce solar arrays arbitrarily according to the increase or decrease of the load to avoid waste.
5) Solar energy is inexhaustible and inexhaustible. The solar radiation received by the earth's surface is 10,000 times the current global energy demand. As long as solar energy is installed in 4% of the world's deserts, it can meet the global needs. It is safe and reliable. Shocked by the energy crisis and fuel market instability.
