Solar-powered equipment has been on the rise due to people becoming more conscious about the environment. Aside from that, technology nowadays offers plenty of options that allow most of the population to afford it.

In fact, in 2019, experts estimated that the solar lighting market alone could possibly reach up to US$ 10.8 billion by 2024.

With that said, there is a greater chance that most residential homes will have indoor solar lighting fixtures both outside and inside in the future.

Of course, outdoor solar lights are simple to understand and often need less maintenance. On the other hand, indoor solar lights can be a bit tricky to handle.

What Are Indoor Solar Lights?

Any light fixtures powered by sunlight and designed to be installed within the house or on a balcony are considered indoor solar lights.

These lights can be as simple as an emergency light to as glamorous as a chandelier. Although some designs can be a bit expensive, they are designed to be long-lasting.

To clarify, light fixtures where the electric source comes from an external solar panel setup are not considered indoor solar lights. Those that are only compact and designed by manufacturers can be categorized as such.

How Does An Indoor Solar Light Work?

All solar lights, whether indoor or outdoor, operates similarly. The sunlight hits the solar panel that is already a part of the fixture’s exterior.

Then, a reaction called the “photovoltaic effect” occurs when DC electricity is on the other end of the panel. However, a battery has to be placed internally to collect all that energy.

If there is no battery, the light will still function when connected directly to the panel’s output. Still, it will not be stable since the lighting activity will depend on the present situation of the sunlight. So, to regulate the energy collected, a battery is needed for storage.

That way, the light fixture will not completely expend the excess energy collected. After all, who needs to turn on the lights when the sun is shining bright? With that said, when sunlight is beginning to diminish, the light can still function out from the stored energy from the battery.

Of course, nowadays, these light fixtures have become more appealing due to other functions. For example, automated features like scheduling when to turn on and control the amount of illumination needed are reasons people are attracted to purchase these products.

Aside from this, having them is also a step towards being environmentally friendly. However, if the light fixtures are installed indoors, how does it gather sunlight?

In general, if some of these light fixtures are installed in a very secluded room, they will not work. Therefore, the usage of these indoor solar lights will depend on how they are installed. There are different indoor solar lights, and each can have differences when it comes to their installation.

Types Of Indoor Solar Lights And How To Install Them

Tube Lights

Solar tube lights are flexible modules of lights. You can attach them to a ceiling and shape your way according to the ceiling design. For them to capture sunlight, there has to be a reflective dome on a roof.

How to Install Them

Map where the reflective dome is favorable to install.

Decide what pattern of the tube lights you are going to make.

Ensure that there are no existing wirings, plumbing, or ventilation that can be damaged during installation

Follow the manual’s instructions on how the fittings and the switches are installed.

Stair Lights

Stair lights aim to illuminate the steps when the sunlight passing through the windows is not enough. Rope lights can also be in the same category since they can be used for the same purpose.

How to install them

Decide whether to illuminate each step or along the railings only. If you decide to go for each step, choose the solar stair lights. If you prefer the railings, then choose rope lights:

Ensure that the steps are directly exposed to a window where sunlight is constantly passing through. If not, resort to rope lights.

See to it when you are about to purchase the stair lights; the type of stairs you have at home can be accommodated.

When mounting the lights, follow the manual’s instructions and use the appropriate mounting screws.

For rope lights, decide how to hang them in the railings.

Place the solar panel part of the rope lights to the nearest window.


Solar skylights are similar to solar tube lights in terms of purpose. However, skylights are most effective when you have an attic, or your interior is incorporated with the attic of your structure.

They are window-design lights wherein, at their core, they are windows, but at night once the shade of the fixture is closed, they can be used as lights.

How to install them

Plot which part of the attic will allow illumination both from sunlight and the electrical lights.

Dig a hole following the manual’s instructions, and install the light fixture.

If a switch is needed, install molding for the pathway of wires.

Lights With Separate Solar Panels

To clarify, this sort of light is different from those mentioned above non-indoor solar lights. The solar panel of this type of light is constructively separated from the central fixture but still connected through the wires. As a result, all of it is still considered a single product.

You can typically use this type of light for ceiling, walls, stairs, and more. Moreover, they are very flexible in terms of their use. However, it would be best to remember that the panel part has to be fixated on a location where there is exposure to sunlight.

Security Lights

This type of light is usually installed right outside the main door, back door, or corner of the house exterior.

Since they are installed technically not inside the house, they can gather sunlight quickly. The best part is that it is equipped with sensors so that they can be used for burglar alarms or emergency illumination.


Indoor solar lights can provide you an alternative not to rely on the conventional electrical source. Aside from this, it can help you contribute to saving the environment and cut down on the costs needed to power your home.

Moreover, indoor solar lights can be long-lasting and also maintenance-free. However, before purchasing, make sure the design of your house allows you to have them installed.
