[Photovoltaic power generation principle]
The principle of the photoelectric conversion process is that photons transfer energy to the electrons to move them to form a current.
【composition】
The solar power generation system is composed of a solar battery pack, a solar controller, and a battery (group). If the output power is AC 220V or 110V, you need to configure the inverter.
1 solar panel
The solar panel is the core part of the solar power system. The function of the solar panel is to convert the solar energy into electricity.
[The advantages and disadvantages of photovoltaic power generation]
(1) Advantages
1 no risk of exhaustion;
2 Safe and reliable, no noise, no pollution, absolutely clean (no pollution);
3 Not limited by the geographical distribution of resources, the advantages of building roofs can be utilized; for example, areas without electricity, and areas with complex terrain;
4 It can generate electricity on site without consuming fuel and erecting transmission lines;
5 high energy quality;
6 users are emotionally acceptable;
7 The construction period is short and the time taken to obtain energy is short.
(ii) Disadvantages
1 The energy distribution density of the irradiation is small, that is, it takes up a huge area;
2 The energy obtained is related to meteorological conditions such as four seasons, day and night and cloudy.
3 At present, generators are costly compared to thermal power generation.
4 The photovoltaic panel manufacturing process is not environmentally friendly.
