What are the different types of Solar Panels?

The increasing energy demands have led to the rise of solar energy adoption as an efficient energy source. In this blog, we will discuss the types of solar panels and have a detailed analysis of them.

As of March 2025, solar energy accounts for a 22% share of India’s total installed capacity and almost 48% of total renewable energy installed.

A solar panel is the most crucial component of a solar energy system.

What is a Solar Panel? A solar panel is a device that captures sunlight and converts it into usable energy for our homes & businesses.

Currently, there are three major types of solar panels:

• Monocrystalline Solar Panel
• Polycrystalline Solar Panel
• Thin-film solar Panel

Every solar panel has various characteristics, including costs, features, efficiency, and more. 

These panels are a long-term investment. Hence. It’s necessary to choose the ideal panel type according to your requirements.

Let’s have a look at these different types of solar panels to understand them properly.

Understanding Types of Solar Panels

Here’s a detailed analysis of all three types of solar panels

Monocrystalline Solar Panels

A monocrystalline solar panel is a PV panel made from a single & pure silicon crystal structure. 

Due to this structure, these panels have a higher efficiency rate as it allows a smooth flow of electrons.

Monocrystalline solar panels are the most efficient type of solar panels, and are the most ideal for low-light and limited space conditions.

These solar panels are created through the Czochralski process, which requires creating a single silicon structure and then slicing it into thin wafers.

Monocrystalline panels usually have a black appearance with circular edges and have a uniform design.

Polycrystalline Solar Panels

Also known as Multicrystalline solar panels. 

Polycrystalline panels are created by melting multiple silicon crystals together. 

As compared to monocrystalline solar panels, polycrystalline panels are slightly less efficient, but still are a good alternative for energy production needs.

They are easy and inexpensive to produce as the silicon is not supposed to be too pure.

These panels have a blueish hue and a grainy appearance and are often placed with silver or white frames.

Thin-Film Solar Panels

These panels are different from the other two traditional panels.

Thin-film solar panels are created by placing one or more photovoltaic materials on a surface such as glass, metal, or plastic.

These panels are very portable & flexible as they are lightweight and can even be rolled up, making them perfect for non-traditional purposes like shops, mobile homes, boats, curved roofs, etc.

Thin-film panels can be made from different types of materials, such as:

• CdTe (Cadmium Telluride)
• a-Si (Amorphous Silicon)
• CIGS (Copper Indium Gallium Selenide)

Compared to other types of solar panels, thin-film panels have lower efficiency, but they perform well even in cloudy or shady conditions.

Cost Considerations

Let’s discuss the cost value of each solar panel type and their ideal usage:

Monocrystalline Panels

• Monocrystalline panels are manufactured using the Czochralski process and have the highest efficiency. Hence, they are the most expensive type of solar panels.
• These panels are ideal for use when maximum energy output is required in a limited space.

Polycrystalline Panels

• Polycrystalline solar panels are easy & cheap to manufacture. Hence, they are available at the most affordable price range.
• These solar panels are the most ideal for large roof spaces, and for moderate energy requirements at a good value.

Thin-film Panels

• Thin-film solar panels have a different price range depending on the materials utilised and the installation process. Majorly, they are very affordable, but some of them might require careful handling.
• These are the best alternatives for lightweight or flexible solar panels or non-rooftop surfaces.

Efficiency & Performance

The efficiency of a solar panel is the rate at which it converts sunlight into usable energy.

Efficiency Ratings:

• Monocrystalline solar panels have an efficiency range of 18% to 22%
• Polycrystalline solar panels have an efficiency range of 15% to 17%
• Thin-film solar panels have an average efficiency of 10% to 14%, but the latest versions can achieve even higher efficiencies.

Roof Space Impact

• For smaller roof areas, high-efficiency solar panels such as monocrystalline are better.
• In case of large roofs or open spaces, polycrystalline or thin-film options are a better, cost-effective alternative.

Temperature Performance

• All solar panel types tend to lose some efficiency in extreme heat conditions.
• Monocrystalline solar panels have better heat absorption than others.
• Thin-film solar panels have better temperature coefficients, allowing them to perform better in hot & shaded climates.

Materials and Construction 

Crystalline Panels (Monocrystalline & Polycrystalline)

• These panels are manufactured using silicon wafer cells.
• They are placed together using rigid metal frames with glass covers.
• These panels are strong and can last over 25 years.

Thin-film Panels

These solar panels are made using different types of materials:

• CdTe is the most commonly used material, which is affordable and highly efficient.

• a-Si is comparatively less efficient, but it’s ideal for portable usage.
• CIGS is light and flexible, with the highest efficiency rate.

Thin-film panels don’t require heavy frames and can be placed directly on the surface.

Visual & Structural Differences

Now, let’s understand the visual & structural identities of these types of solar panels.

Monocrystalline Solar Panels

• These panels have a solid black colour.
• It has a refined design with rounded edges.
• It has a very clean & compact structure, providing an aesthetic look to your panels.

Polycrystalline Solar Panels

• These panels have a bluish, textured, grainy look.
• The design is slightly bulky with sharp edges.
• The structure of this panel is less uniform, but it’s still practical.

Thin-film Solar Panels

• The colour varies from black, blue or semi-transparent depending on the product.
• It has a simple, ultra-thin design like a sheet.
• These panels have a curvy or flexible structure, and are mostly preferred where traditional panels can’t be placed.

How to choose the Right Panel for you?

Space & Efficiency

• In case of space restrictions, Monocrystalline solar panels are the most viable option for high energy generation.
• For large areas and ground space, Polycrystalline & Thin-film panels are the best fit.

Budget Impact

• Polycrystalline panels offer the right balance between time & money.
• For high budget & energy requirements, Monocrystalline solar panels are ideal.
• For portable & temporary requirements, Thin-film panels are the best.

Specific Applications

• Residential use: Monocrystalline panels have high efficiency, and polycrystalline panels are cost-effective.
• Commercial use: Thin-film panels are easy to install on large surfaces.
• Portable use: Thin-film panels are preferred due to their lightweight and flexibility.

Conclusion

Choosing the right category is the best way to increase solar panel efficiency in 2025.

Let’s have a quick look at the pros of each type of solar panel.
