Solar energy is the only inexhaustible, clean, pollution-free and renewable green energy on earth.
Therefore, solar power generation, with unparalleled cleanliness, high safety, sufficient and extensive energy, long service life, and maintenance-free, has the advantages and characteristics that other conventional energy does not have, and is favored by people.
Solar street lamps do not need to lay cables, AC power supply and electricity charges; It adopts DC power supply control; The utility model has the advantages of good stability, long service life, high luminous efficiency, simple installation and maintenance, high safety performance, energy conservation, environmental protection, economy and practicality.
Therefore, solar street lamps are installed on both sides of roads in many rural areas, and solar street lamps in rural courtyards are also very common.
What are the types of solar street lamps in rural yards? And how to choose?
It is mainly selected from the following four aspects:
1. Choose light source: solar street lamps generally use LED light source, and the most used are 1W high-power lamp beads. Generally, the power of one lamp bead is 1W, and generally the number of lamp beads is the number of watts.
2. Solar panels: solar street lamp panels generally use single crystals and polycrystals. The price of single crystals is higher than polycrystals. If customers buy them, they do not have professional measuring instruments. It is recommended to use size and area to measure. The larger the size and area, the higher the power. The size of the solar panel is directly proportional to the power.
3. Battery: solar street lamp battery is generally divided into lead-acid battery, colloidal battery and lithium battery. At present, colloidal battery and lithium battery are commonly used. The cost of lithium battery is higher than colloid, and colloid is higher than lead-acid battery.
4. Lamp pole: the height, shape and parameters of the lamp pole are mainly considered. The higher the height of the lamp pole, the corresponding parameters should be increased, and the price will also increase. The more complex the shape of the lamp pole, the price will also increase.
