Developments such as industry have led to an increasing demand for energy in all countries. The problem of energy shortage has become a major obstacle. The solar photovoltaic market was born in this context and has developed rapidly. For daily lighting, the LED solar light has reduced daily power consumption and is very environmentally friendly. LED solar lights, with the advantages of LED DC low voltage operation and energy saving and environmental protection, have the advantage of 0 power consumption for solar photovoltaic conversion. Next we will introduce you how to source cost-effective LED solar lights.
I.Basic Operation Principle of LED Solar Lights
First of all, let's understand the basic operation principle of LED solar lights, so as to better know the places to pay attention to when purchasing LED solar lights.
Solar led lights use sunlight as the source of energy, charging during the day and using at night, without complicated and expensive pipeline laying, can be adjusted at will the layout of the lamps, safe, energy-saving and pollution-free, and no manual operation work stable and reliable, saving electricity, maintenance-free. The solar led light is mainly composed of solar cell component part (including bracket), led light head, control box (with controller and battery) and light pole. Solar energy is converted into light, thus achieving the advantage of environmental protection and 0 power consumption.
II.Introduction & classification：Solar street light/Solar flood light/Solar garden light
LED solar lights are currently divided into solar street lights, floodlights and garden lights, depending on the application scenario. Among them, LED solar lights are widely used is the solar street light. As solar street lights are used outdoors, they have higher requirements for the materials used in street lights. Solar floodlights are more suitable for use in homes, hotels and other scenarios. There are also portable models, so there are relatively more options. The solar garden lights are more unique in style and shape, as shown in the picture below.
III.Introduction to basic functions and material requirements
The basic functions of the general LED solar light are: automatic light on when it is dark, constant power on cloudy and rainy days, and electricity saved during the day for lighting at night.
Optional intelligent light control, automatic lighting, lighting more intelligent and more convenient to use.
Optional light body material is die-cast aluminium for better heat dissipation and is fixed with stainless steel screws.
As solar lights are often used outdoors, the requirements for the material and performance of the light body are higher. Both the lamp and the lamp head have to meet the sealing requirements to prevent damage to the street lamp caused by thunderstorms, thus extending the service life.
IV.Choice of solar panels
For LED solar lights, the photoelectric conversion efficiency is more important, and this depends mainly on the performance of the solar panel.
The main function of solar panels is to convert light energy into electricity, i.e. the photovoltaic effect. Among the more common and more practical are mainly monocrystalline silicon solar cells, polycrystalline silicon solar cells and amorphous silicon solar cells .
1)Polycrystalline silicon solar cells are relatively simple to produce and can be much cheaper than monocrystalline silicon cells. The conversion efficiency is lower compared to monocrystalline cells, but it has been improving in recent years and is suitable for areas with sufficient sunlight and good sunshine.
2)Monocrystalline solar cells have more stable electrical performance parameters and are suitable for areas where there are more rainy days and relatively less sunlight.
3)Compared to polycrystalline silicon and monocrystalline silicon, amorphous silicon solar panels require less sunlight and can achieve high photoelectric conversion efficiency even when the sunlight is weak indoors.
V.Battery selection
When choosing an LED solar light, the quality of its battery is also a factor to be considered. A large capacity battery lasts a long time and at the same time can provide enough current for the instantaneous start of high-powered electrical equipment. For some high-powered electrical equipment, it is recommended that the battery should be 200AH (<1000W), and when the power is even greater, a 400AH battery can be used. So, how to determine the capacity of the battery according to the led solar street light appliances used. The simple method is to multiply the power of all the appliances used by the amount of time the battery is used between each charge.
A good choice of solar panels and batteries can increase the range of the light body to achieve full lighting effect. Of course, you can also choose the appropriate quality according to your needs. I believe that through the above introduction, you must have a certain understanding of how to purchase cost-effective LED solar lights.
