Introduction and working principle of solar street lamp

Luz Solar Para Calles are street lamps powered by crystalline silicon solar cell, with maintenance free valve controlled sealed battery (colloidal battery) to store electric energy, super-bright farola LED as light source and controlled by intelligent charge discharge controller, which is used to replace traditional public electric lighting.

    Solar energy is inexhaustible, clean, pollution-free and renewable green, color ring and energy conservation. Solar power generation has unmatched advantages such as cleanliness, high safety, relative universality and sufficiency of energy, long life and maintenance free. Photovoltaic energy is considered to be a very important new energy in the 21st century. Solar street lamps do not need to lay cables, AC power supply and electricity charges; DC power supply and control; It has the advantages of good stability, long service life, high luminous efficiency, simple installation and maintenance, high safety and safety performance, energy saving, environmental protection, economy and practicality. It can be widely used in urban main and secondary roads, communities, factories, tourist attractions, parking lots and other places. Product parts: lamp pole structure: steel lamp pole and bracket, plastic spraying treatment on the surface, and special anti-theft stainless steel screws are used for battery board connection.

    Description of working principle of solar street lamp: under the control of intelligent controller, the solar panel absorbs solar light and converts it into electric energy after being irradiated by solar light during the day. The solar cell module charges the battery pack during the day, and the battery pack provides power to the luz de alta de mástil alto source at night to realize the lighting function. The DC controller can ensure that the battery pack will not be damaged due to overcharge or discharge, and has the functions of optical control, time control, temperature compensation, lightning protection, reverse polarity protection, etc.

    Core technology and development trend of Sistema De Energía Solar: with the development and progress of solar photovoltaic technology, it is first applied to lighting lamps in civil use. In recent years, due to the dual advantages of environmental protection and energy saving, solar garden lamps, solar lawn lamps and solar decorative lamps have gradually formed a scale. How to choose an economical and practical solar lamp product that is more suitable for local climate conditions in many dazzling commercial advertisements? This has always been the user's final question?

    In the design of solar lighting fixtures, many factors are involved in the light source, solar cell system and battery charge and discharge control. Any problem in any link will cause product defects. Let's first understand the composition of solar lamps!

    Solar cell

    The main function of solar baterías is to convert light energy into electric energy. This phenomenon is called the photovoltaic effect. Among many solar cells, monocrystalline silicon solar cells, polycrystalline silicon solar cells and amorphous silicon solar cells are more common and practical. In the eastern and western areas with sufficient sunlight, polycrystalline silicon solar cells are better. Because the production process of polycrystalline silicon solar cells is relatively simple and the price is lower than that of monocrystalline silicon. The conversion efficiency has been continuously improved in recent years. It is better to use monocrystalline silicon solar cells in southern China where there are more rainy days and less sunshine, because the electrical performance parameters of monocrystalline silicon solar cells are relatively stable. Of course, amorphous silicon solar cells are better when the indoor sunlight is very weak, because amorphous silicon solar cells have low requirements for solar lighting conditions.
