Solar panels have become synonymous with clean energy, but their performance behind glass presents an intriguing puzzle. In this blog, we’ll try to determine whether solar panels can work through glass and assess whether this configuration impacts their efficiency.
Can Solar Panels Work Through Glass?
Yes, solar panels can work through glass, but they won’t be as effective as when they’re set up outdoors. The decrease in efficiency is influenced by factors like the panel’s quality, the amount of sunlight it receives, the thickness of the glass, and how clean the glass is. Now, let’s find out whether solar panels can work through tinted glass, plastic, and plexiglass.
1. Can Solar Panels Work Through Tinted Glass?
Solar panels work best when they get direct sunlight. If you use them indoors behind tinted glass, like a tinted car window, it will affect their efficiency. But, even with some sunlight, they can still function.
The tint on the window blocks only half of the sunlight, allowing the other half to pass through and reach the panel, powering it.
2. Can Solar Panels Work Through Plastic?
After learning can solar panels work through glass, let’s find out the same for plastic. Certainly, solar panels can operate effectively through clear plastic. However, it’s crucial to understand that various types of plastic exist, each with its distinct properties.
The efficiency of a solar panel depends on the specific type of plastic employed. While it’s generally believed that plastic may decrease a solar panel’s efficiency, there are scenarios where it can be a more suitable choice.
Recent research has unveiled that plastic can serve as a viable photovoltaic material by itself. Consequently, scientists are actively working on the development of plastic solar cells, anticipating increased durability and cost-effectiveness as notable advantages of this innovation.
3. Can Solar Panels Work Through Plexiglass?
After learning that solar panels can work through glass, let’s now find out if they can work through plexiglass.
Plexiglass, also known as acrylic sheet or acrylic glass, is a durable and safe plastic material. It’s favored for constructing solar panels due to its durability, resilience in harsh weather, and shatter-resistant properties.
Furthermore, Plexiglass permits ample sunlight to pass through to the solar panel, making it an excellent choice for their construction. Now, let’s put some focus on the efficiency of solar panels behind glass.

What is the Efficiency of Solar Panels Behind a Glass?
The efficiency of solar panels can take a hit when they’re placed behind glass, potentially reducing their effectiveness by up to 50%. This decline in efficiency is based on several factors, including the strength of the incoming sunlight, the size of the solar panels, the type of glass used, its thickness, and how clean it is.
The main reason for this is how light behaves when it goes through glass. Some of it bounces back, and some pass through but at a different speed and angle. So, even though solar panels behind glass still work, they lose a lot of energy. This means fewer sunlight particles (photons) make it to the panel’s surface, resulting in lower electricity production compared to panels in the open sun.
In simpler terms, solar panels can charge through glass, but they don’t work as well as those out in the open sun because some of the sunlight gets lost when it goes through the glass.
If your solar panels are facing efficiency issues, you can try these 16 ways to increase solar panel efficiency. Now, let’s discover the reasons why solar panels are put behind glass.
Reasons Why Solar Panels are Put Behind Glass
As you are aware of the fact that solar panels can work through glass, let’s explore the reasons why solar panels are put behind glass:
- Portability: This placement provides a portable option for charging devices like phones or laptops while traveling.
- Security Concerns: In neighborhoods where theft is a concern, solar panels, which can be expensive, might be targeted. Placing a small panel in the yard could also raise security concerns. So people place the panels indoors behind glass windows.
- Camper or Motorhome Use: Many individuals prefer not to drill holes in the roof of their camper or motorhome for solar panels. Instead, they find that the large windows provide a convenient and secure location for mounting solar panels.

How can Solar Panels be Optimized to Work More Efficiently behind Glass?
The points below explain how solar panels can be optimized to work more efficiently behind glass:
- Position the panels near a south-facing window: This helps them get the most direct sunlight.
- Use a small, movable panel: These can be adjusted throughout the day to catch the most sunlight.
- Keep the panels as close to the glass as possible: This reduces energy loss from things like window reflections or shading.
- Open a window to let in more daylight: This can also help increase the amount of sunlight the panels receive.
In summary, solar panels can function through glass, but their efficiency depends on multiple factors such as glass quality, cleanliness, and exposure to sunlight. While they may not be as effective as open-air installations, they’re still a viable choice. To learn more interesting facts about solar panels, keep coming back to our blog.
