Do You Know How Solar Panel Street Light Works?

Solar energy is the cleanest energy source on the earth. As a huge amount of renewable energy, the radiant energy reaching the surface of the earth every day is approximately equal to 250 million barrels of oil, which can be said to be inexhaustible. With the development of technology, solar energy is more and more widely used in our life, such as solar water heaters, solar panel street lights and so on. Especially in the lighting industry, solar panel street light has become an important part of outdoor lighting. The biggest difference between solar panel street lights and traditional street lights is that it completely relies on solar power. Some new users are skeptical about this. Will solar panel street lights run out of electricity after use? How does it generate electricity, and if it can't generate electricity, will it fail? In this article, we will give you a detailed introduction to how solar panel street lights work.

Solar panel street lights are composed of crystalline silicon solar panels, batteries, intelligent controllers, light sources and other accessories. Solar panel street lights are recognized by users due to a series of advantages such as low carbon, environmental protection, safety and reliability, and thus have been vigorously promoted. They are widely used in urban arterial roads, highways, communities, tourist attractions, parking lots and other places. Its working principle is to convert solar energy into electric energy to realize lighting. On the top of the street lights are solar panels, also known as photovoltaic modules. During the day, these polysilicon photovoltaic modules convert solar energy into electrical energy and store them in batteries. Under the control of the intelligent controller, the solar panel is irradiated by sunlight, absorbs the sunlight and converts it into electrical energy. At night, the power is delivered to the light source through the control of the controller to illuminate people at night.

Solar panel street lights generate electricity through solar energy, so there is no cable, and there will be no leakage and other accidents. A well-equipped intelligent controller can ensure that the battery is not damaged due to overcharging or overdischarging, and it has multiple functions such as time control and light control. So as long as there is the sun, the solar panels can be charged to store electrical energy for night lighting. The service life of solar panels on the market can reach 25 years, so as long as the solar panels are properly maintained, there is no need to worry about the problem of electricity conversion. Even in the cloudy day, solar street lamps can also illuminate normally. When configuring solar panel street lights, the street light manufacturer should be informed of the maximum number of rainy days. In this way, when configuring the battery and solar panel capacity of the street lamp, it is necessary to fully consider the customer's lighting needs, so as to give a reasonable configuration. Under normal circumstances, the stored electric energy of solar panel street lights in sunny days can support 5-7 days of cloudy lighting.

High-quality accessories are also a guarantee for the normal lighting of solar panel street lights. Commonly used solar panels can be divided into monocrystalline silicon and polycrystalline silicon, and the power conversion rate of monocrystalline silicon solar panels is higher. The successful application of LED light sources in the street lamp industry also provides a strong guarantee for the installation of solar street lamps. Almost all the spectrum of the LED is concentrated in the visible light band, so the luminous efficiency is high. Moreover, LED is more energy-efficient than energy-saving lamps by a quarter, which is a great reform of solid-state light sources. Batteries are the core components of street lights. Commonly used batteries include gel batteries, lead-acid batteries, and lithium batteries. Nowadays, there are more street lights using lithium batteries, because lithium batteries have low pollution and long service life. The role of the intelligent controller is also very large, and it needs to stabilize the voltage.
