How to get cost-effective LED solar lights
Developments such as industry have increased the demand for energy in all countries. The problem of power shortage has become a major obstacle. The solar PV market was born in this context and developed rapidly. For daily lighting, the LED solar light has reduced daily energy consumption and is very environmentally friendly. LED solar lights, with the advantages of LED DC low voltage operation, energy saving and environmental protection, has the advantage of 0 power consumption for solar photovoltaic conversion. Next, we will introduce you to how to get cost-effective LED solar lights.
Firstly. The basic operating principle of solar LED lights
First, let’s understand the basic operation principle of solar LED lights, so as to know where you should pay better attention when purchasing solar LED lights.
Solar LED lights use sunlight as the energy source, charge during the day and use at night, without laying complicated and expensive pipelines, can be adjusted at will, safe, energy-saving, pollution-free, no manual operation, stable and reliable, save electricity, do not need maintenance. Solar LED light is mainly composed of solar cell component part (including bracket), LED light head, control box (with controller and battery) and lighting pole. Solar energy is converted into light, thus achieving the advantage of environmental protection and zero energy consumption.

secondly. Introduction and classification： solar street light/solar floodlight/solar garden light
Solar LED lights are currently divided into solar street lights, flood lights and garden lights, depending on the application scenario. Among them, the most widely used solar LED lights are solar street lights. Because solar street lights are used outdoors, higher requirements are required for the materials used in street lights. Solar flood lights are more suitable for use in homes, hotels and other scenarios. There are also portable models, so there are relatively more choices. Solar garden lights are unique in type and shape, as shown in the image below.
Third. Introduction to basic functions and physical requirements
The basic functions of the general LED solar light are: automatic lighting when it’s dark, stable power on cloudy and rainy days, and saving electricity during the day for lighting at night.
Optional intelligent lighting control, automatic lighting, lighting more intelligent, more convenient to use.
Optional light body material is die-cast aluminum for better heat dissipation and is bolted with stainless steel.
Since solar lights are often used outdoors, the material and performance requirements of the light body are higher. Both the lamp and the lamp head must meet the sealing requirements to prevent the street lamp from being damaged by thunderstorms, thus extending the service life.
Fourthly. Selection of solar panels
For solar LED lights, photoelectric conversion efficiency is more important, which mainly depends on the performance of solar panels.
The main function of solar panels is to convert light energy into electricity, that is, the photovoltaic effect. Among the most common and most practical are monocrystalline solar cells, cosmic polycrystalline silicon solar cells, and amorphous silicon solar cells.
1) Polycrystalline silicon solar cells are relatively easy to produce and can be much cheaper than monocrystalline silicon cells. The conversion efficiency is lower compared to monocrystalline cells, but it has improved 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 with more rainy days and relatively less sunlight.
3) Compared with 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.
Fifth. Battery selection
When choosing a solar LED light, its battery quality is also a factor to consider. The large capacity battery lasts for a long time and at the same time can supply enough current for instant start of high power electrical equipment. For some high-power electrical equipment, it is recommended that the battery be 200Ah (less than 1000W), and when the power is greater, a 400Ah battery can be used. So, how to determine the battery capacity according to the solar street lighting devices used. The simple method is to multiply the power of all devices used by the amount of time the battery is used between each charge.
A good selection of solar panels and batteries can increase the range of the light body to achieve the 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 solar LED lights.
