Photovoltaics based on power supply type
DC power system and AC power system
-
According to the characteristics and types of the power supply
Divided into independent photovoltaic power generation systems and grid
connected photovoltaic power generation systems
-
Is there any noise hazard in photovoltaic power generation systems?
The photovoltaic power generation system converts solar energy into
electrical energy without generating noise effects. The noise index of the
inverter is not higher than 65 decibels, and there is no noise hazard.
-
Does photovoltaic power generation system pose electromagnetic radiation
hazards to users?
The photovoltaic power generation system converts solar energy into
electrical energy based on the principle of photovoltaic effect generated by
light. It is pollution-free and radiation free, and electronic devices such
as inverters and distribution cabinets have passed EMC (electromagnetic
compatibility) testing, so it is not harmful to human health.
-
How to deal with the temperature rise and ventilation issues of solar cells?
The output power of photovoltaic cells will decrease with increasing
temperature, and ventilation and heat dissipation can improve power
generation efficiency. The most commonly used method is natural wind
ventilation.
-
What should be paid attention to in fire prevention and firefighting of
household distributed photovoltaic power generation systems?
Flammable and explosive materials are prohibited from being stacked near
distributed power generation systems. In the event of a fire, the personnel
and property losses caused are incalculable. In addition to basic fire
safety measures, photovoltaic systems are also reminded to have self
detection and fire prevention functions to reduce the likelihood of a fire.
In addition, fire prevention and maintenance channels must be reserved every
40 meters, and there must be emergency DC system circuit breakers that are
easy to operate.

The main advantages of solar photovoltaic power generation
Isolation temperature. Heat insulation in summer and block cold in winter.
-
Photovoltaic power generation reduces the rate of roof aging
After installing photovoltaic panels on the roof, it can block direct
sunlight from shining on the roof, reduce the aging rate of roof tiles, and
extend their service life.
