Solar street light consists of the following components: solar panels, solar controller, battery, light source, light poles and lamp housing. If the output power to 220V AC or 110V, but also configure the inverter.
Height of poles should be based on the width of the road, lighting the space, the road illumination standard-setting. Lamp housing according to our collection of sun light a number of foreign materials between the aesthetic and energy saving, most of them choose energy-efficient, less demanding exterior lighting, the relative utility on the line.
Solar panels and solar lights in the central part of the solar lights in the highest value. Its role is to the sun’s radiation is converted to electrical energy, stored in batteries or sent. Among the many solar cells in general and more practical than a single crystal silicon solar cells, polycrystalline silicon solar cells and amorphous silicon solar cells, three. Sunny sunshine too good in the east and west, the use of polycrystalline silicon solar cells as well as polycrystalline silicon solar cell production process is relatively simple, lower price than the single crystal. More rainy days in the sun is relatively not very abundant in the southern region, using single crystal silicon solar cells as well as single crystal silicon solar cell performance parameters more stable. Amorphous silicon solar cells in the absence of sufficient sunlight outside is better, because the amorphous silicon solar cells on solar illumination conditions require relatively low.
Solar street lamp solar light in what is an important indicator of normal use, the general energy-saving lamps solar lamps use low pressure, low pressure sodium lamp, lamp, DLED light. Low energy-saving lamps: power is small, light-efficient, but the service life of 2,000 hours, low voltage lamp black, generally suitable for solar lawn lights, garden lights. Low-pressure sodium lamp: high efficiency low pressure sodium lights, but the need inverter, low pressure sodium expensive, making the entire system is high, use less. Lamp: power is small, light-efficient. The lamp in 220V (pure sine wave, frequency 50 Hz) under normal conditions of use of electricity, life can be up to 50,000 hours, life in the Solar Modules light on energy-saving lamps greatly reduced and almost ordinary. LED light source, long life, up to 1 million hours, low voltage, no inverter, light-efficient, made 50 Lm / w, imports of 80 Lm / w. As technology advances, LED performance will be further enhanced. I believe that the LED light source as solar street light will be a trend.
