Some Basic Knowledge about Solar Photovoltaic Power Generation

1. How to deal with the temperature rise and ventilation problems of solar cells? The output power of photovoltaic cells decreases with the increase of temperature. Ventilation and heat dissipation can improve the power generation efficiency, and natural ventilation is the most commonly used method.

2. Does the photovoltaic power generation system have electromagnetic radiation hazards to users? The photovoltaic power generation system converts solar energy into electricity based on the principle of photoelectric effect, which is pollution-free and radiation-free. Electronic devices such as inverters and distribution cabinets have passed EMC (electromagnetic compatibility) tests, so they have no harm to the human body.

3. Is there any noise hazard in the photovoltaic power generation system? The photovoltaic power generation system converts solar energy into electricity and does not produce any noise. The noise index of the inverter is not higher than 65 decibels, so there is no noise hazard.

4. What issues should be paid attention to for fire prevention and firefighting in household distributed photovoltaic power generation systems? Flammable and explosive materials are prohibited from being stored near the distributed power generation system. Once a fire occurs, the resulting loss of life and property is immeasurable. In addition to basic fire safety measures, it is particularly reminded that photovoltaic systems have self-detection and fire prevention functions, which can reduce the possibility of fire. Moreover, fire and maintenance channels must be reserved at intervals of no more than 40 meters, and there must be an easy-to-operate emergency DC system circuit breaker.

  Advantages of Photovoltaic Power Generation:

1. Solar energy is infinite and sufficient. The solar radiation energy received by the earth's surface is sufficient to meet the current global energy demand 10,000 times over. Installing solar energy in 4% of global deserts can meet global needs. Solar energy is safe, reliable, and not subject to the impact of energy crises and fuel market instability.

2. Solar energy is available everywhere and does not require long-distance transportation, avoiding losses in long-distance power transmission lines.

3. Solar energy generation has no moving parts and is not easily damaged, and maintenance is simple.

4. Solar energy generation does not produce polluting waste during the process, making it an ideal clean energy source.

5. The construction period of the solar energy generation system is short, convenient, and flexible. Solar energy arrays can be added or reduced arbitrarily according to changes in load, avoiding waste.
