View: 103302/21/2020  

In the modern society where new energy is constantly replacing old energy, the use of solar energy can be said to be very good, which can make the energy we need in our lives more clean and pollution-free. And street light is an indispensable part of our life, which provides us with very good benefits when we walk on the dark road. In the past, streetlights generally used electric lighting. This part of the electricity comes from coal energy and old energy. Now, the emergence of solar streetlights has greatly changed the situation of streetlights in the past and can make our lives cleaner and more environmentally friendly.

20W solar street light

The price of 20W solar street light is related to its equipment. 

The price of 20Wsolar street light mainly focuses on the four parts of light pole, battery board, LED light source and battery. 

1. It depends on the specific height of the solar street light pole the customer wants, such as 4m, 8m or 12M, which is the demanding choice. Different pole heights are calculated by shares, and different pole prices are obtained.

2. Look at the price of the solar light composition. For example, the solar kit for daily operation is mainly composed of solar street light battery panel, solar street light battery, solar street light controller and solar battery box.

3. The price of double arm solar street light is also different from that of single arm solar street light. Double arm street light needs two battery panels, so the cost will be higher. Others, such as cables and pre buried cages, have little difference.

Selection details of 20W solar street light

1. LED light source, most of the solar street lights on the market are selected LED light sources, and most of them are selected with 1W high power in terms of light beads, so in general, the power of a light bead is 1W, so we can choose appropriate light beads according to the specific application environment so that we can fully play the role of lighting.

2. The price of a single crystal is higher than that of polycrystalline. Many unscrupulous manufacturers will reduce the 50W to 40W for assembly, and the layman is ugly. That is to say, it is difficult to find problems even if there is no professional instrument measurement for the insiders. Therefore, it is suggested that we can measure the scale area according to the scale area. When the scale area of the battery board reaches, the greater the power of the battery board is, and vice versa. Therefore, we can choose our battery board according to this law.

3. The battery is a very important part of the structure of solar street light. Generally, there are three kinds of battery: lead-acid battery, lithium battery and gel battery, which can only be classified. Different types of batteries have different functions. Now we use more colloid and lithium battery. The cost of lithium batteries is higher than the other two, so we can make a reasonable choice according to our own needs and economic ability.

4. Generally, the height and shape should be considered for the pole of solar street light. The higher the height is, the higher the price will be. Otherwise, if the shape of the pole is messy, the price will increase relatively. Therefore, we should try our best to summarize and consider the selection of appropriate height and shape according to different places and needs.

5. The poor quality of the controller will lead to excessive discharge, which fails of lighting time to meet the requirements, and will cause great damage to the battery. The above content is the principle, structure, advantages and disadvantages, price and purchase details of the solar street light which is compiled by xianji.com and shared by us today. I believe you know something about solar street light. Nowadays, energy conservation and environmental protection are being promoted nationwide, and solar street lights are popular because of their superior energy-saving function and pollution-free low-carbon lighting. Solar street lights will also become the mainstream trend of lighting in the future.
