How To Charge Solar Light Without Sun?

Table of Contents

Introduction:

A common and environmentally friendly choice for outdoor lighting is solar lighting. They use solar panels to produce energy from sunshine. The availability of direct sunshine may only sometimes be possible, though. This post will examine additional strategies for how to charge solar lights that don’t require direct sunlight to keep your lights operating even in adverse weather.

Does Direct Sunlight Make Solar Lights Work?

The inner parts of solar lights are operated with solar energy, which is captured and changed into electrical power. Solar lights can be charged under indirect or diffused sunshine, albeit direct sunlight is the most effective way. Without direct sunshine, the charging process slows down considerably and is less efficient.

The Optimum Way to Charge Solar Lights:

It is advised to place your solar lights in direct sunlight as often as possible to achieve optimum charging outcomes. Put them where they can get as much daytime sun exposure as possible. Your solar lights will operate at peak efficiency and deliver the highest performance.

Can I Charge Solar Lights Indoors?

If the solar light you are using is lightweight, then you can definitely bring them indoors for charging. You can also use regular light bulbs, or the other option is by placing them near windows. You could also charge them using your laptop or solar power banks if they have a USB charger.

How To Charge Solar Lights Insides?

When there isn’t access to direct sunshine, charging solar lights indoors might be a practical solution. Solar lights can be charged using artificial light sources like LED or fluorescent lighting. It’s crucial to remember that not all interior lighting may be charged by the sun. Look for light origins that are more high-powered and have a colour temperature related to that of the sun. Position the solar lights as close to the inside light source as possible to maximize the charging process.

Can solar lights be charged by indoor lights?


You are able to charge the solar lights by using artificial lights or regular power bulbs. The reason is that the solar lights require visible light for working. LED bulbs, incandescent bulbs, flashlights, and other artificial lights can be also used.

Solar lights are able to charge without sunlight only if they are placed underneath household lights directly underneath your panels.and for If the solar lights are not able to be charged by sunlight, then  place them close to artificial illumination or incandescent bulbs. It could take considerably longer for charging a solar panel if the solar lights have been separated from the lights.

LED lights can be also used in the absence of other sources for indoor lighting. The solar light can be charged through an LED source for up to 8 to 12 hours.


How to Charge Solar Lights Outside:

Some spots may need more sunshine or be shaded even in outdoor locations. In these circumstances, you can improve solar charging by using a variety of approaches. Mirrors and white walls that reflect light can assist in directing and intensifying sunlight toward the solar panels of your lighting. Additionally, solar lights can be strategically placed in places with fewer impediments to increase charging effectiveness.

Does Rain Affect Solar Light Charging?

Rainy days present a difficulty for solar charging because the diminished sunshine intensity and cloud cover greatly impact the charging process. Rainy days might allow solar lights to charge to some extent, but realizing that the charge rate will be significantly slower is crucial. Ensure the solar panels are clean and free of any dust and dirt that could stop sunshine from gaining them to increase solar charging during bad weather.

Are Solar Lights Capable of Charging Through Windows?

While solar lights can receive some charge through windows, the efficiency is far lower than with exposure to direct sunshine. Typically, windows include coatings and filters that can partially obscure the sunlight for charging. If charging solar lights through windows is the only choice, put them as close to the window as possible and ensure the window gets enough sunlight all day.

What Is the Lifespan of Solar Lights?

The feature of the product, how it is used, and how well it is sustained is some unsteady factors affecting how long solar lights last. Solar lights typically last between two and five years. The most important factors that affect how long solar lights last are the solar panels and rechargeable batteries. Please ensure the solar panels are cleaned regularly, batteries are changed as needed, and the lights are shielded from harsh weather to increase lifespan.

Design of Solar panels while capturing sunlight

For charging them without solar light you need to know their design. When light shines on a photovoltaic or in a short term (PV) cell it is also known as a solar cell it can do his work for light reflecting, absorbing, or passing right through the cell.

As we know that The PV cell is composed of semiconductor material. And When a semiconductor is exposed to light,  it absorbs the light’s energy and uses it to transfer it to negatively charged particles in the material which are called electrons. This amount of extra energy allows the electrons to flow into the material as an electrical current. And as we know that this current is extracted into conductive metal contacts and the grid like lines on solar panel’s cell  and able to use them to power your house.

As we know The efficiency of a solar cell can be known by the amount of energy that it can extract from the light source. This thing  largely depends on your light  characteristics, for example: its intensity and wavelengths. And you know that the Longer wavelengths have less energy and the shorter ones have more.

The “band gap” of your PV semiconductor is known as a key feature, and is used to know which wavelengths of light it can absorb and convert it to power. This will also translate to a limited range of wavelengths, with its cell ignoring those that are longer or shorter. And if the semiconductor’s band gap matches to the wavelengths of light shining on your panel’s PV cell, it can be efficient to make use of the available energy.

You need to know that the Solar cells have been specifically designed for absorbing the sunlight. And  A standard silicon solar cell responds to the most of visible parts of a sun’s light spectrum, maybe half of the infrared light, and a part of the ultraviolet light.

Charging with Indirect Sunlight

Clean your solar panels when using them in cloudy weather

 Sunlight will still reach your solar lights in cloudy weather, although not as much as in sunny weather. Cleaning any dust, dirt, or grime off the surface of the panels will thus help your solar lights charge more efficiently and make better use of limited sunlight.

  • Be very gentle when cleaning your solar panels. Use clean water and a microfiber cloth to scrub the dirt and grime off of your lights.
  • Avoid using detergents to clean the solar panels; these may cause streaking that could actually make it harder for the panels to charge.
  • If you’re in an area that has a lot of dust, pollen, sandstorms, or fires, wash off the layers of dust, pollen, dander, or ashes with a hose

Move the lights to be in the best position for receiving limited sunlight

This solar panel has to be seated on an Angle, where  the solar panels directly face the sun as it moves in the sky. That is important in winter, when we face less sunlight available throughout the day.

Use mirrors to redirect sunlight to your lights, if needed.

And If your solar panels are positioned underneath a shadow,  then you have to place a mirror nearby as that reflects sunlight onto the panels. We know that, This is not  a very efficient solution, though, so you only need to resort to this if you are not able to move the solar lights yourself into a better position.

Turn off the lights and let them charge more efficiently for 72 hours. 

If the solar lights will charge much more efficiently at a time when they’re turned off. Make sure to leave them outside in a place where they would still receive as much sunlight as possible.

Using Artificial Lighting

Charge your solar lights with light from an incandescent bulb

 As we know, The light from most incandescent bulbs is able to charge a solar light, but overall it is not as effective as natural sunlight. For doing so, Place the solar panels directly underneath a household light for charging them as quickly as possible without having sunlight.

Use LED lights to charge a solar light when you’re far from home

There are also  Battery-operated LED lights, such as LED flashlights, that are also able to charge solar lights. This method is known as the best way to charge your solar lights when you are not able to have access to indoor lighting, like at a time when you are camping.

Avoid placing your solar lights near street lights or porch lights

When you notice that the solar lights are exposed to their  high-intensity light in the evening time, then their sensitivity will decrease over time. For if you want to have best results, try to place your lights as far away from artificial light as possible while using them in the evenings.

Use An Alternative Charging Method

There are also Some solar LED lights available that can have an alternative charging method through a USB charger. If you have one of them then you use this method to charge, this allows you to plug it to a wall socket or power bank. Overall this option might be more costly for you than the previous options, but  you can use this biggest opportunity if it’s more convenient for you.

How Long Do Solar Lights Stay on at Night?

Well the answer is quite simple: these solar lights receive sun rays in the day, the longer there are some  chances that they will run at night. They need about 6 hours in the sunlight for being fully charged and this thing/battery will help them to run up to about 8 hours on a good charge. 

How Do You Charge Solar Lights Without the Sun?

This question might also come into your mind.  You can charge solar lights without using sunlight so now it is possible you just have to place solar panels directly underneath a household light to charge them speedily. Try to Place your solar lights close to an artificial lighting or incandescent bulb to charge solar lights without sunlight. As we know  if the solar lights are away from the light bulbs, they would take longer to charge the solar panel.

Do You Need Direct Sunlight to Charge Solar Lights?

The answer is clearly No, solar lights are not needed for direct sunlight to charge solar lights.On the other hand , solar lights just  need light in some form to power them on. But this process can be produced without the presence of sun’s light. As we described first, solar lights can get charged by using artificial light, incandescent bulbs or LED lamps, etc.

Can I charge my solar lights with a flashlight?

Using a flashlight to charge solar light is now possible when it is in a form of artificial lighting. Charge speed and the efficiency, moreover, it will be affected by the brightness of a flashlight to charge solar lights.

As you know , Solar lamps convert visible light into a form of electricity with the help of a visible spectrum of light. But still the regular flashlights emit about 300lum only, that brightness is surely not so high, however, it will take much more time to charge the solar light by using a flashlight.

So, Now you can easily charge solar lights even though it may take a long time to charge. You can also use a flashlight to charge your solar light.

Charging solar cells in artificial light is a waste of energy

In a short answer, there is no real and perfect, efficient or logical reason to try and power your solar cells and charge solar lights with artificial light.

No artificial light can not be able to charge solar lights and mimic the strength and radiance of true sun rays, and surely not at the level needed to perform efficiently. Just like you wouldn’t bother using a candle to cook your food, you would be wasting your time, your energy and literal energy trying to charge your solar panels with an artificial light.

And those are looking at ways to maximize their solar generation, or reduction in charge solar lights and consumption when there is limited or no sunlight, it is worthwhile considering high-efficiency solar panels and a solar battery for storing your solar-generated electricity for using it at night or on cloudy days.

As you know that the Energy Matters has assisted over 30,000 Australians in their transition for cleaning energy. We can guide you for solar and for a battery storage solution that will fit your lifestyle and cost.
