Solar lamps are loved by many customers because they are energy-saving and environmentally friendly, easy to install and easy to use. But some people still don't know how solar lamps are charged, and whether they can be charged only by sunlight. In fact, no. solar lamps can be charged by any kind of light. But if you want to fully charge the solar lamp to get lighting time as long as you want, you can charge it in sunny days for 6-8 hours in the sun, and it will light up for 8-10 hours at night.
In recent years, solar lamps have become more and more popular. They are energy-saving and environmentally friendly, easy to install and easy to use, and can help people save living costs and realize a low-carbon, environmentally friendly and sustainable lifestyle. However, there are many questions about solar lamps that still plague people. For example, how long do solar lamps need to be lit before they are fully charged? Only the sun's rays could recharge them, couldn’t it? Can they get enough electricity if it keeps raining for many days? Are they not going to light up after some continuous raining days? This blog will discuss two things: first, the charging time of solar lamps; second, if the continuous sunlight time is insufficient, can solar lamps still light sufficiently at night?
1. How long does it take to fully charge the solar lamp?
In theory, as long as there is light, (it could be any kind of light), solar lamps can absorb and convert it into electricity. But strong sunlight will make the conversion rate higher; other light sources can also be converted into electricity, but the conversion rate could be very low, so the solar lamp will be on for a short time and the brightness is not high. It can be charged in sunshine for 6-8 hours on a sunny day, and can be turned on for 8-10 hours at night. Charging on cloudy days with 6-8 hours of sunshine, and 4-6 hours of light at night.
The advantages of chargeable solar lamping lamps are energy saving and environmental protection, no need for wires, installation anywhere, and absolute safety. Automatically turn off the light and charge during the day, and automatically turn on the light when it is dark. When people approach, it provides higher-brightness lighting, and when people leave, it turns to lower-brightness, taking into account the needs of lighting and decoration. A solar lamp usually has a variety of working modes for setting, and the two function buttons distinguish between induction and long-light functions, which are simple and clear. This energy-saving function could help the solar lamp save electricity stored inside so that it could be on for a longer time, which could be particularly useful on those cloudy days.
2. Can solar lamps be charged with other than sunlight?
A solar panel is a device that could observe any kind of light and convertsit into electricity. In theory, solar panels can be charged with any kind of light. However, the strength of a light source could determine how much electricity a solar lamp could get. In other words, a strong light source could provide sufficient electricity for the solar lamp so that it could work for a longer time. A poor light source might lead to a shorter lighting time of the solar lamp.
The solar panel is the core and the most valuable part of the solar power generation system. Its function is to convert sunlight into electricity before storing it in the battery. The quality of solar panels will directly determine the quality and cost of the entire solar lamping system. Usually, the storage battery is lead-acid. In a small and micro system, a nickel-metal hydride battery, a nickel-cadmium battery or a lithium battery is also used to store the electricity converted by solar panels and release it when needed. If the storage capacity of the battery is high, it will store much power when there is sufficient sunlight. In the case of rainy days with little sunlight, the solar lamp will continue to be on for a long time thanks to the electricity stored in the battery.
3. Does the solar lamp require direct sunlight to be charged?
Solar street lights do not have to be charged by direct sunlight. During the day, the solar panel observe sunlight and then converts it into electricity. During the day, the solar battery was charged with electricity; at night the battery pack provides power to light LED lights in the solar lamp. The remote can ensure that the battery will not be damaged due to overcharging or over-discharging. Besides, the remote has some other functions such as brightness control, time control, temperature compensation, lightning protection, and reverse polarity protection. Under normal circumstances, a solar lighting system can guarantee the light for more than 10 days in rainy weather.
In theory, solar lamps can convert all kinds of light into electricity and store it in the battery. But the conversion rate is high only when the strong sunlight hits the solar panel directly. Fortunately, the battery can store electricity for lighting at night, so the solar lamps can also be used for a period of time in rainy days.
