Solar energy is all hype nowadays and it is not surprising why. This form of renewable energy has a lot of benefits that make it an attractive option for homes and businesses alike. However, one common misconception about solar energy is that it can only be harnessed when the sun is out. Learn how to charge solar lights without sun.

Solar lights are a popular option for those who want to take advantage of solar energy. They are relatively inexpensive and easy to install, making them a great choice for those who are looking to save on their energy bill.

However, if you live in an area where it is cloudy or the sun does not shine often, you may be wondering how you can charge solar lights without the sun.

There are a few different ways that you can charge solar lights without the sun. This article will discuss three different methods that you can use to charge your solar lights.

The following are some methods you can employ to charge your solar lights without direct sunlight:

1. Clean the Solar Panels

Your panels will be unable to absorb as much energy from the sun if they are covered in dirt or leaves. Make sure to keep them clean so that they can function at peak efficiency.

Also, over time panels can accumulate a build-up of grime that can disrupt light absorption. You can clean your panels with a vinegar solution (1 part vinegar to 3 parts water) or purchase a commercial solar panel cleaning kit. Don’t use harsh chemicals or abrasives on your panels as this can damage them.

2. Reposition the Angle of the Solar Light to Receive Limited Sunlight

If you live in an area with long winters and short days, it’s important to position your solar panels so that they can maximize the amount of sunlight they receive. The best way to do this is to orient them towards the south at an angle that is equal to your latitude.

For example, if you live in Atlanta, Georgia (latitude 33 degrees North), then your solar lights should be positioned at a 33-degree angle towards the south. This will ensure that they receive the maximum amount of sunlight possible.

Keep in mind to keep moving and angling the solar lights around accordingly so that they can get the most exposure if you’re desperate and that nothing obstructs or shades them.

3. Use Mirrors to Reflect Sunlight

If you don’t have direct access to sunlight, you can use reflective material to boost the amount of sunlight that your solar lights receive. For example, you can place a piece of mirror or aluminum foil under the solar panel to reflect additional light onto it.

When using an item such as a mirror, make sure that it is positioned so that the sunlight is reflected directly onto the solar panel. You don’t want to waste time by reflecting sunlight onto an object that isn’t in direct contact with the solar panel.

The larger the mirror, the more sunlight will be reflected onto the solar panel. So, if you have multiple mirrors, you can position them around the solar panel to create a “sunlight station” of sorts.

4. Switch Off the Solar Light and Let it Charge for 72 hours

The panels will be more effective at charging the battery if they’re turned off while they’re charging. This is because the panels will have a higher voltage when they’re turned off, which allows them to store more energy.

After 72 hours have passed, turn the solar light back on and see how long it lasts. If it doesn’t last as long as you’d like, repeat the process. It’s also known as the “deep charge” and is a great way to charge your solar lights to their fullest potential.

Now, here are some methods you can use to charge your solar lights with artificial lighting:

1. Use a Light Bulb to Charge Solar Lights

You can use a halogen bulb to charge your solar lights. Halogen bulbs are incandescent bulbs that contain a small amount of halogen gas. This gas allows the bulb to produce more light than a regular incandescent bulb. 

Although, a simple incandescent light bulb will also work to charge your solar lights. You’ll just need to keep it close to the solar panel since these bulbs don’t produce as much light. Also, make sure to use a low-wattage bulb so that it doesn’t overheat the solar panel even though it will take longer to charge the solar lights.

2. Use LED Lights to Charge a Solar Light

LED lights can also get the job done, but they’ll take longer to charge the solar lights than direct natural sunlight.

We recommend using an LED light that has a high lumen output. This will help to speed up the charging process. Also, make sure to keep the LED light close to the solar panel since these bulbs don’t produce as much light.

Some flashlights that use LED bulbs can also work to charge your solar lights. Just make sure to keep the light close to the solar panel since these bulbs don’t produce as much light.

How Long Does It Take to Charge a Solar Light?

This is difficult to gauge and give an accurate answer to since there are many variables involved such as the wattage of the solar panel, the type of battery, the size of the battery, if it’s a deep cycle battery if you’re using a reflector, what time of day it is, etc.

In general, though, it’ll take about 8-10 hours for the solar light to get a full charge. If you’re using a reflector to amplify sunlight, then it’ll take less time. And if you’re using an LED light to charge the solar lights, then it’ll take longer.

It really all depends on your specific situation. But 8-10 hours is a good estimate for how long it’ll take to fully charge a solar light.

Can you charge a solar light with a flashlight?

The answer is yes, you can charge a solar light with a flashlight. Just keep the light close to the solar panel since these bulbs don’t produce as much light. Flashlights are usually small, so you might need to use multiple flashlights to get the job done or keep it on for a longer period of time.

Can you charge a solar light through a window?

In all honesty, it’s not the best idea to try and charge a solar light through a window. The glass will filter out some of the sunlight, which means it’ll take longer to charge the solar lights. If you’re in a pinch and don’t have any other choice, then go for it. Although keep in mind, that it’ll take longer to charge the solar lights this way.

How do you charge solar lights on a cloudy day?

You can still charge solar lights on a cloudy day, but it’ll take longer since there’s less sunlight. We recommend using a reflector to amplify the sunlight or using an artificial light source such as an LED light bulb. Just keep in mind, that the amount of light that’s available will determine how long it’ll take to charge the solar lights.

Conclusion 

So, there you have it! These are a few methods you can use to charge your solar lights without direct sunlight. First of all, you can use a halogen bulb or an LED light. And secondly, you can use a reflector to amplify sunlight or an artificial light source. Just keep in mind, that the amount of light that’s available will determine how long it’ll take to charge the solar lights. Thanks for reading!
