Charging solar lights without sun can use indirect sunlight such as artificial lighting, LED lights, USB, or improve the charging efficiency of solar light. Solar power is an excellent source of renewable energy. It reduces your carbon footprint and electricity bills. The best way to charge solar lights is in direct sunlight. The solar panels convert the sunlight into electricity, giving power to the solar lights all night. You don’t have access to direct sunlight without sun, such as on rainy days, in winter, or indoors.
The sun is not the only way to charge solar lights. You can still charge solar lights without the sun. In overcast or winter, you can charge solar lights with indirect sunlight. In addition, an effective way to charge solar lights without sun is to improve the charging efficiency of solar lights. Such as cleaning solar panels, adjusting the angle of the solar panels, using mirrors to reflect sunlight, and doing a long charge.
Artificial Incandescent Bulbs
Incandescent light has characteristics that emit light waves similar to sunlight. So you can charge solar lights in artificial incandescent bulbs without sun. Incandescent light bulbs are about 80% as efficient as sunlight. While it is not as efficient as sunlight, it can still provide enough power for your solar lights. You just need to place the solar lights about 20 inches away from the incandescent bulbs for a few hours. Most light bulbs produce between 40-100 watts of light. The bigger the wattage, the faster your solar lights will charge.
You can charge solar lights with LED bulbs without sun. LED lights emit visible light, long infrared waves, and ultraviolet waves. These waves are the same as those produced by the sun. LED lights can charge solar lights when you don’t have access to indoor lighting. While using LED lights, you need to charge the solar panel for more than 10 to 12 hours.
Many solar lights come with USB ports, so you will not have to rely on sunlight or artificial lights. You can directly charge the lights using any power bank or your laptop.
Improve the Charging Efficiency of Solar Light
An effective way to charge solar lights without sun is to improve the charging efficiency of solar lights.
Clean Solar Panels
Solar panels can collect dust and grime as time passes. They gather on the panels, blocking the sunlight from reaching the solar panel. In addition, the dirt will eventually cause rusting in the metal components of your solar panel. To charge solar lights more effectively when without sun. Please clean solar panels regularly.
Adjust the Angle of the Solar Panels
As we all know, the sun rises in the east and sets in the west, which is still the case even without the sun. So you can adjust the angle of the solar panel so that it directly faces the sun. This maximizes charging efficiency. To do this, you’ll have to adjust the position of the solar panels throughout the day. This is especially important in winter or rainy when there’s less sunlight available throughout the day.
Use Mirrors to Reflect Sunlight
You can angle mirrors to reflect more sunlight onto your solar panels. This is an efficient way to get the most out of the sun without sun. It can increase the amount of diffuse sunlight our solar lights receive. However, you need to look at where the sun is in the sky and keep repositioning the mirror throughout the day.
Do a Long Charge
Typically, it takes 6-10 hours of direct sunlight to fully charge the solar lights. However, it takes longer on cloudy days, winter, or other low sunlight. When charging solar lights during the day, turning off the solar lights will make the charging more efficient. Also, turn off solar lights at night to ensure maximum capacity for charging.
There are many ways to charge solar lights without direct sunlight. You can charge them indoors or outdoors. Solar lights can get a charge even when there’s no presence of sunlight. It can be done with the help of incandescent light bulbs, LED lights, etc.
