Developments such as industry have increased 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 reduces daily energy consumption and is very environmentally friendly. LED solar lights, with the advantages of DC LED low voltage operation, energy saving and environmental protection, have the advantage of 0 power consumption of solar PV energy conversion. Next, we will introduce you how to get LED solar lights cost-effectively.

Firstly. Basic operating principle of solar LED lights

First, let’s understand the basic operation principle of solar LED lights, so as to better know what places to pay attention to when purchasing solar LED lights.

Solar LED lights use sunlight as the power source, charging during the day and use at night, without laying complicated and expensive pipelines, can be adjusted at will, safe, energy-saving and pollution-free, no manual operation Stable and reliable, electricity saving, no need maintenance. Solar LED light is mainly composed of solar cell component part (including series), 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 flood light/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 LED solar lights are solar street lights. Since solar street lights are used outdoors, they have higher requirements for the materials used in the 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 options. Solar garden lights are unique in type and shape, as shown in the picture below.

Third. Introduction to basic functions and physical requirements

The basic functions of general LED solar light are: automatic lighting when it is dark, constant power in cloudy and rainy days, and electricity saved during the day for lighting at night.

Optional intelligent lighting control, automatic lighting, smarter lighting, more convenient to use.

The optional light body material is die-cast aluminum for better heat dissipation and is secured with stainless steel bolts.

Since solar lights are often used outdoors, the material and performance requirements for 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 prolonging its service life.

Fourthly. Choosing solar panels

For solar LED lights, the photovoltaic conversion efficiency is more important, and this mainly depends 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 most common and most practical are monocrystalline silicon solar cells, 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 they have improved in recent years and are suitable for areas with sufficient sunlight and good sunlight.

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 with polycrystalline silicon and monocrystalline silicon, amorphous silicon solar panels require less sunlight and can achieve high photovoltaic conversion efficiency even when the sunlight is weak indoors.

Fifth. Battery selection

When choosing a solar LED light, the quality of its battery is also a factor to consider. The large capacity battery lasts for a long time and at the same time can provide enough current to instantly start 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 larger, a 400Ah battery can be used. So, how to determine the battery capacity according to the solar street lighting devices used. A simple method is to multiply the power of all devices used by the amount of time the battery is used between each charge.
