Solar lights have their power source from the sun, but solar energy is not the sole way for you to recharge the solar lights. There are many prominent alternatives that will be efficient to refill your solar lights’ energy in case of absent sunlight in your areas. Our “How to charge solar lights without sun?” will show you all the possible methods.

How To Charge Solar Lights Without Sun?
We will show you all the optimal ways to refill the solar lights’ batteries no matter where you place the lights, indoors or outdoors.
Indoor Solar Lights Charging
Honestly, indoor charging has never been the best solution to the solar lights’ lack of battery. The reason is that the indoor environment can’t offer your solar lights renewable and clean energy. On the contrary, you have to utilize energy from other types of electric stuff to generate power for the solar lights.
However, these three following methods will help when the outside condition is not preferable for recharging your solar lights.
#1 Take Advantage Of Incandescent Bulb
Ironically, people rely on solar energy to get rid of electrical power, but this solution is going in the opposite way. Don’t worry. The method is still helpful when there’s little sunlight in your region.
Let alone the complicated electronic knowledge explain why incandescent bulbs can replace sunlight, and we will give you a more straightforward answer. Natural sunlight and incandescent light share the same way to emit light waves. Fortunately, this type of lightwave stimulates the solar cells so that they can process the lightwave into energy.
Recharging your solar lights using incandescent bulbs will take you several hours. Hence, if you plan to use the solar lights the next morning, you should charge them tonight. The perfect distance for you to place the solar lights from the incandescent lights to properly refill the battery is about 20 inches.
The incandescent lights’ charging efficiency is not as great as natural sunlight. In specific, you should expect that incandescent bulbs can generate eight out of ten energy portions that sunlight can provide the solar lights.
Sunlight only needs about 4 hours to fully recharge the solar-powered lights, whereas incandescent light will require 6 hours to give solar lights adequate power.
The light bulbs’ wattage will decide the solar lights’ recharging speed. So, you can minimize the charging time by opting for high-wattage bulbs.
#2 LED Lights Are Decent Choice
LED lights’ characteristics are relatively the same as the incandescent bulbs, so they are also similar to sunlight. By that, we mean the waves from the LED lights will be an appropriate power source for your solar lights. Ultraviolet waves, visible light, and long infrared waves from LED lights will efficiently contribute to the solar light’s sustainability.
Among these three elements above, ultraviolet waves are the only section that differs natural sunlight from the indoor alternative. Sunlight’s ultraviolet waves are superior to those produced by LED lights.
However, this situation is tolerable because no one wants their house to be filled with a high ratio of ultraviolet waves. Constant exposure to ultraviolet waves will lead to severe health conditions.
Solar lights are an economic power source because they can save up your budget on electricity bills. Therefore, this solution should be the last resort to refill the solar lights’ battery. You can recharge the solar lights via wall sockets or various types of power banks.
Believe it or not, using electricity is the most convenient and accessible way among these three indoor charging methods. But, it is the most expensive way. Besides, this method will go against the environmentally friendly orientation of solar lights.
Outdoor Solar Lights Charging
The outdoor charging methods will come into effect when there is sunlight outside, even with the least ratio.
#1 Small Beams Of Light Still Work
There has been a common misconception that solar lights can’t receive energy from sunlight during rainy, gloomy, or cloudy days.
In fact, small beams of light can still reach the solar lights’ PV cells. And they will provide the lights with a proper portion of energy no matter how distant and hot the light beams are.
Particularly, the solar lights will get charged more efficiently in the winter due to the cold temperature. When the temperature decreases, it will prevent the solar lights’ electrons from aggressively moving around. As a result, a higher voltage will lead to better energy production.
#2 Rely On Mirror Reflection
In some cases, the sunlight can’t get to your place because of huge obstacles like buildings or trees. Mirrors are here to help. You can take advantage of the mirror’s reflective feature to adjust the sunlight’s direction so that the natural energy can reach your solar lights.
Although this method is clean and sustainable to reproduce energy, it will take your effort to alter the mirror’s position to catch the sunlight.
Some Notice When Opting For These Methods
LED lights and incandescent bulbs can generate excessive heat when you leave them open for long hours. Therefore, you should be careful when touching these items, or else your bare skin may get burnt. Moreover, if you allow close contact between the consecutive-active bulbs and flammable items, there will be a possibility of a fire.
You should opt for adapters to modify the electricity level when charging your solar lights via electricity. Exaggerated electricity levels can do damage to the lights’ components.
Sunlight is always the cleanest and most sustainable energy source for solar lights. However, sunlight is absent in some areas hindering the recharge of solar lights. We have shown you how to charge solar lights without sun. You can manage to refill the lights battery by carefully following our tutorial.
