How Solar Path Light Works

Update:14 Jan

 

Solar Path Light uses the principle of the photovoltaic effect to make solar cells. During the day, the solar panels receive solar radiation energy and convert it into electrical energy for output, which is stored in the battery through the charge and discharge controller. At night, when the illuminance is gradually reduced to about 10lux, the solar panels are open-circuited. The voltage is about 4.5V. After the charge and discharge controller detects this voltage value, the battery discharges the lamp head! The simplest way: the solar panel will absorb the solar energy and convert it into electrical energy, and store the electrical energy in the battery for use at night. . Batteries are divided into lead-acid batteries and gel batteries.

 

During the daytime, under the control of the intelligent controller, the solar panel absorbs the solar light and converts it into electrical energy. During the daytime, the solar panel charges the battery pack, and at night, the battery pack supplies power to the LED light source to realize lighting. Features. The DC controller can ensure that the battery pack is not damaged due to overcharge or over discharge, and has functions such as light control, time control, temperature compensation, lightning protection, and reverse polarity protection.

 

When installing solar street lights, there is no need to set up complicated circuits, just make a cement base, make a battery pit, and fix it with galvanized bolts. No need to consume a lot of human, material, and financial resources. Solar street lights are a one-time investment and long-term benefit. Due to the simple wiring, there is no maintenance cost and no expensive electricity bills. The cost is recovered in 6-7 years, and more than 1 million electricity and maintenance costs are saved in 3-4 years. It can save the high electricity cost of the city circuit lights, the complicated circuit, and the need for long-term uninterrupted maintenance of the circuit. Especially in the case of unstable voltage, it is unavoidable that the sodium lamp is easy to break, and with the extension of the service life, the aging of the line and the maintenance cost is increasing year by year.
