About Solar Lights Basic Information

A solar light is an outdoor lighting fixture that operates using solar energy. Unlike traditional lighting systems that rely on electricity from the grid, solar lights harness energy from the sun through photovoltaic (PV) panels.they are designed to convert sunlight into electricity during the day and store it in batteries for use at night or when sunlight is not available.

Some solar lights are set to charge even when they are OFF, but some solar lights are set so that the switch must be turned on to charge during the day. Please refer to the manual for details.

Yes, all solar lights have batteries, because the working principle of solar lights is to convert light energy into electrical energy through the solar panel, and then store it in the battery. The battery releases energy and supplies it to the LED to make it glow.

Solar lights are usually equipped with a light sensor, also known as a photoresistor or photocell. A light sensor is a device that senses the intensity of surrounding light. When the ambient light intensity drops below a certain level (usually a certain lux value), the light sensor will detect this change and trigger the solar light to work.

About Solar Lights Installation Location

No, as long as solar lights can be exposed to sunlight, they can work properly. If there is direct sunlight, the charging speed will be faster. The working principle of solar lights is to convert solar energy into electrical energy using solar energy, which is then stored in batteries for use by the lamps. Therefore, solar lights need sunlight to charge during the day and use the stored electrical energy for lighting at night. It is important to note that although solar lights can still work under cloudy or shady conditions, the effectiveness will be greatly reduced because sufficient sunlight is a key factor in ensuring that solar lights charge and provide adequate brightness.

Yes, Solar lights can work inside, but solar panel need to be placed near windows so that sunlight can penetrate through the glass. The more abundant the light, the faster the charging speed of the solar lights will be.

Solar lights can only be charged a little in the shade, and a little bit of electricity is not enough to support the normal operation of the solar lights. Therefore, it is not recommended to install solar lights in the shade.

If you want solar lights to work indoors, there are two methods. The first is to install the solar lights close to the window, allowing sunlight to shine through the window onto the solar panel; the second is to install a split solar light, so that the solar panels are placed outdoors and the solar lights stay indoors.

About Charging Solar Lights

Solar lights illuminate the solar panel through sunlight, and then the solar panel converts the light energy into electrical energy and stores it in the battery. The battery then provides energy to the LED to emit light. Therefore, sunlight is essential.

Yes, but it’s very, very inefficient because solar panels are usually designed to absorb sunlight from natural sunlight, which contains enough energy to generate electricity. While solar panels can also absorb artificial light, their efficiency is often compromised. The spectrum and intensity of artificial light are different from those of sunlight, which will also lead to a reduction in the electrical energy conversion efficiency of solar panels because it basically has no effect in actual use.

Conventional solar lights must rely on sunlight for charging. If you want to charge without sunlight, you can choose a solar light with USB, so that you can use household electricity to charge the solar light.

No, because conventional LED lights do not have the same spectrum as sunlight, so solar panels cannot convert light energy into electrical energy.

About Solar Lights Work In Extreme Weather

Solar lights can be charged on rainy days, but they can only be charged a little, so it is difficult to maintain the normal operation of the solar lights. Based on this situation, it is recommended to adjust the lighting mode of the solar lights to 0+PIR on rainy days, as well. The solar lights only turn on when people come over.

Solar lights can be used in winter, but the lighting time will be greatly shortened because there is insufficient sunlight during the day, so the battery cannot have enough energy to supply the solar lights. It is recommended to adjust the solar lighting mode to 0+PIR when winter comes. , which can achieve practical and power-saving purposes.

It is difficult to charge solar lights when there is no sunlight. Therefore, if you must use solar lights when there is no sunlight, it is recommended to purchase solar lights with a TYPE-C socket.

Our products are designed for use in environments ranging from 0°C to 65°C. Even in snowy conditions, the internal temperature of the product remains higher than the external temperature, allowing the lights to function normally. During the day, when the sun comes out, the snow melts into water and automatically flows away, which does not affect solar charging.

About Cleaning Solar Lights

The places where solar lights can be cleaned include lampshades, solar panels and brackets. All three parts can be cleaned with clean water first. If there are impurities that are difficult to clean, you can use regular household soap or dishwashing detergent. It should be noted that Please turn off the solar lights before cleaning. After cleaning, you need to dry the various parts before putting them together.

1. Before cleaning your solar panel, first make sure it has cooled down. Use a soft cloth or sponge to gently wipe the solar panel surface to remove dust, dirt, and other impurities.
2. Use warm water to gently rinse the solar panel surface to remove residual dirt and contaminants. Avoid using high-pressure water guns or high-temperature water to prevent damage to the solar panels.
3. If there are stubborn stains or dirt on the surface of the solar panel, you can use a mild detergent or soapy water, dissolve the detergent in warm water, and then gently wipe the surface of the solar panel with a soft cloth or sponge.

On cloudy days, you could not rush to clean the solar panels. It is recommended to wait until it rains and let the rain clean the solar panels naturally. Generally speaking, rain can automatically wash away the dust on the surface of the solar panels. If some impurities are difficult to be washed away by the rain, Can be cleaned manually using dish soap.

It is normal for solar panels to accumulate dust and other debris. When there is wind or rain, these obstructions are usually automatically cleared. Dust does not typically accumulate in thick layers over large areas on the surface of solar panels. Even if there is a small amount of dust, it will not significantly affect the power output of the solar panels.
