With more and more solar fence post cap appearing in cities, the advantages of solar fence post cap in saving energy and promoting environmental protection are gradually known and understood by people. Today, solar fence post cap light suppliers introduce the structure of more solar fence post cap from the root level. Solar fence post cap is mainly composed of the following parts: solar panel, solar controller, storage battery and light source.

1. Solar panel: As the center of solar fence post cap, solar panel is undoubtedly the most valuable part of solar fence post cap. Its function is to convert the light energy output by the sun into electric energy, and send it to the storage battery for storage. Solar photovoltaic panels are mainly divided into polysilicon solar cells, monocrystalline silicon solar cells and amorphous silicon solar cells.

2. Solar controller: For a high-quality solar fence post cap, a controller with outstanding performance is an essential component. A controller with outstanding performance can effectively regulate the charge and discharge of the cap light, avoid overcharge and deep charge of the battery, and thus prolong the service life of the battery.

3. Battery: Because the input energy of solar photovoltaic system is unstable, it is generally required to configure battery system for operation. The selection of battery capacity should comply with the following criteria: on the premise of ensuring night lighting, the energy of solar cell modules should be stored as much as possible during the day, and at the same time, it should be able to store the electric energy that meets the lighting requirements at night in successive rainy days. If the capacity is too large, the battery will always be in power shortage, which will not only cause waste, but also affect the life of the battery.

4. Light source: What kind of light source to choose is very important for the normal operation of solar column cap lights. Generally, low-voltage energy-saving lights, low-voltage sodium lights, electrodeless lights and LED light sources are selected for solar lights.
