Types of Solar Panels: A Beginner’s Guide

There are three major types of solar panels: monocrystalline, polycrystalline, and thin-film. The best solar panel for your installation will depend on your needs and the specific factors related to your property. Let’s take a closer look at the pros and cons of each type.

Types of Solar Panels

How Expensive Are Different Types of Solar Panels?

Each type of solar panel comes with a different price tag due to differences in how they are made.

  • Monocrystalline Solar Panels: These are usually the most expensive solar panels. They are made from a single crystal of silicon, which is a costly and energy-intensive process. This process is called the Czochralski method and can result in wasted silicon. But don’t worry; this wasted silicon can still be used for making polycrystalline panels.
  • Polycrystalline Solar Panels: These are typically less expensive than monocrystalline panels. They are made from silicon fragments rather than a single crystal, which makes them cheaper to produce. This means you can save money on your installation.
  • Thin-film Solar Panels: The cost for thin-film panels can vary. The cheapest type to make is cadmium telluride (CdTe), while copper indium gallium selenide (CIGS) panels are more costly. Overall, thin-film installations tend to be less expensive than monocrystalline or polycrystalline because they are lighter and easier to handle, reducing labor costs.

How Efficient Are Different Types of Solar Panels?

Each type of solar panel has different efficiency levels, which tells you how much power it can produce. If you have limited roof space, it’s best to choose high-efficiency solar panels.

  • Crystalline Solar Panels: Monocrystalline panels are the most efficient, with over 22% efficiency and power capacities of over 300 watts (W), with many exceeding 400 W. Polycrystalline panels rarely go above 17% efficiency and tend to have lower wattages.
  • Thin-film Solar Panels: These usually have lower efficiency, around 11%. Their power capacity can vary based on size. Generally, monocrystalline or polycrystalline panels will produce more power per square foot than thin-film panels.

What Are Solar Panels Made Out Of?

Solar panels are made up of solar cells that use semiconducting materials to convert sunlight into electricity. Silicon is the most common material used in making solar cells.

  • Crystalline Solar Panels: Both monocrystalline and polycrystalline panels use silicon wafer cells. Monocrystalline cells are cut from a single crystal of silicon, while polycrystalline cells are made by melting multiple silicon fragments together.
  • Thin-film Solar Panels: These panels can be made from various materials. The most common type is made from cadmium telluride (CdTe), which uses a layer of CdTe between transparent layers to capture sunlight. Other thin-film types include amorphous silicon (a-Si) and copper indium gallium selenide (CIGS), each with its unique materials and methods.

What Do Different Solar Panel Types Look Like?

Solar panels can look different based on their materials and how they are made. If you want panels that blend in with your roof, pay attention to these details.

  • Monocrystalline Solar Panels: These are usually black because of the pure silicon used. They come in various colors for the back sheets and frames, often black, silver, or white.
  • Polycrystalline Solar Panels: These typically have a bluish hue because of the way light reflects off the silicon fragments. They often have silver frames and white or silver back sheets.
  • Thin-film Solar Panels: These panels are usually slimmer and may come in both blue and black colors. They can be less visible from the ground and are often used in portable systems.

What Type of Panel Is Best for Your Installation?

Choosing the best solar panel depends on your specific needs. If you have plenty of roof space, you might consider installing lower-cost polycrystalline panels. However, if you have limited space and want to save more on your electric bills, high-efficiency monocrystalline panels would be a better choice.

Thin-film panels are often used for portable solar systems, like those on RVs or boats. They are also good for commercial buildings that can handle the lower efficiency because they have more roof space.

Conclusion

When deciding on the best solar panel for your needs, consider the types of solar panels available, their costs, efficiency, and how they look. Whether you’re interested in high-efficiency solar panels or more budget-friendly options, there’s a solar solution for you in Pakistan. Make an informed choice to start your journey toward renewable energy!
