What should I pay attention to when buying solar garden lights?

Nowadays, many home gardens will consider choosing solar garden lights when choosing the corresponding lamps. At the same time, it can also show that solar garden lights have very high value, so if you buy bad solar garden lights, it will affect the whole garden. It will not play a very good decorative role. So what should you pay attention to when buying solar garden lights?

1. Load

Solar lighting products have the advantages of energy saving and environmental protection. Of course, the load should be energy saving and have a long life. We generally use LED lamps, 12V DC energy-saving lamps and low-pressure sodium lamps. Most lawn lamps use LED as the light source, the LED has a long life, can reach more than 100,000 hours, and has a low operating voltage, which is very suitable for use in solar lawn lamps. Garden lights generally use LED lights or 12V DC energy-saving lamps. The voltage of DC energy-saving lamps is DC, which is convenient and safe without an inverter. Street lamps generally use 12V DC energy-saving lamps and low-pressure sodium lamps. Low-pressure sodium lamps have high efficiency but are relatively expensive, and are used less frequently.

2. Solar panels

The main function of solar panels is to convert light energy into electrical energy, a phenomenon called the photovoltaic effect. Among the many solar cells, the most common and practical ones are mainly monocrystalline silicon solar cells, polycrystalline silicon solar cells and amorphous silicon solar cells. In the eastern and western regions with sufficient sunlight, it is better to use polycrystalline silicon solar cells. Because the production process of polycrystalline silicon solar cells is relatively simple, its price will be much cheaper than that of monocrystalline silicon cells, and the conversion efficiency has also been improved in recent years. In the southern region where there are more rainy days and relatively less sunshine, it is better to use monocrystalline silicon solar cells, because the electrical performance parameters of monocrystalline silicon solar cells are relatively stable. Amorphous silicon solar cells are better in the case of weak indoor sunlight because amorphous silicon solar cells have lower requirements for solar lighting conditions.

3.Solar energy storage battery

Because the input energy of the solar photovoltaic power generation system is not stable enough, it generally needs to be equipped with a battery system to work, and solar lamps are no exception and must be equipped with a battery to work. Generally, there are lead-acid batteries, Ni-Cd batteries, and Ni-H batteries. Their capacity selection directly affects the reliability of the system and the price of the system.

4. Solar charge and discharge controller

No matter the size of solar lamps, charging and discharging control circuit with good performance is essential. In order to prolong the service life of the battery, its charging and discharging conditions must be limited to prevent the battery from being overcharged and deeply discharged. In addition, because the input energy of the solar photovoltaic power generation system is extremely unstable, the control of the battery charging in the photovoltaic power generation system is more complicated than the control of the ordinary battery charging. For the design of solar lamps, success and failure often depend on the success and failure of the charge and discharge control circuit. Without a charge and discharge control circuit with good performance, solar lamps will not be easy to use.

The above points to pay attention to when purchasing solar street lights are shared here. In addition, when purchasing solar garden lights, you need to see if there is a more professional after-sales service. Many manufacturers can provide on-site installation services.
