The two main types of solar panel technology are thin-film and crystalline silicon. Both technologies have advantages and disadvantages, so it’s important to understand the differences before investing in a system.
In this guide, we will compare thin-film and crystalline silicon solar panels to help inform your decision.
What are Thin Film Solar Panels?
Thin-film solar panels are photovoltaic (PV) solar cells constructed of thin layers of a semiconductor material such as amorphous silicon, cadmium telluride, or copper indium gallium selenide.
They are created using the deposition process wherein the thin semiconductor layers are put onto a substrate material such as glass or metal, electrically linked and sealed to shield them from environmental elements.
Thin-film solar panels are lighter, thinner, and more flexible than traditional solar panels, making it easier for them to carry and install. They are also less expensive than standard solar panels due to the less complex production process.
They are more durable than crystalline panels because they have lower temperature coefficients. However, they are not as efficient at converting sunlight into electricity, with light-to-voltage conversion efficiency between 10 and 15%.
What are Thin Film Solar Panels Used For?
Thin film panels are an excellent solution for residential houses and businesses. The panels are easy to place on rooftops, walls, or other surfaces, making them an excellent choice for anyone looking for a simple, cost-effective solution to create electricity.
Thin film panels with high energy efficiency ratings are also commonly used in large-scale solar power projects and battery storage systems. Another potential use for thin-film solar cell panels is solar blinds because they can be folded and stored when not in use.
What are Crystalline Silicon Solar Panels?
Crystalline solar panels, which have been used for decades, are the most efficient and widely used type of solar panel on the market. These solar panels are produced via “crystallization,” creating a single crystal silicon bar in a high-temperature oven. The silicon ingot is then sliced into thin wafers and assembled into a circuit.
Crystalline Solar panels have greater efficiency ratings than thin-film competitors, which means they can convert more of the sun’s energy into usable power. They have a greater voltage rating but are more expensive due to the intricate production process. However, they are becoming more affordable as the price of silicon falls.

What are Crystalline Silicon Solar Panels Used For?
Crystalline panels are the most common type of solar panel used in residential and commercial applications due to their higher efficiency and reliability. These solar panels can power nearly anything you can think of.
They are used in homes to create energy for a household’s electricity demands and in commercial settings to power factories and office buildings. They can also be used in concentrated solar power plants to collect, convert, and send power to the electric grid. Other uses include powering food trucks, electric vehicles, satellite space, etc.
The Difference between Crystalline Silicon and Thin Film Solar Panels
Thin film and crystalline solar panels differ in cost, efficiency, size, etc. Here’s the breakdown:
Crystalline silicon solar panels are more efficient than thin film solar panels, converting more than 20 percent of the sun’s energy into useful electricity. They can absorb light from a vast spectrum, allowing them to operate well in any daylight condition.
On the other hand, thin-film solar panels typically have a light-to-voltage conversion rate between 10 and 12 percent. However, they can absorb light from a wide spectrum, including ultraviolet and infrared. This increases their efficiency in low-light settings, such as sunrise and sunset or overcast days.
Crystalline solar panels are often the more expensive alternative due to their better efficiency and durability. On the other hand, thin film solar panels are typically less expensive because of their lower performance. But they require fewer installation materials, resulting in a lower initial setup cost.
Use thin film solar panels if you want to save money in the long term. Even the payback periods are often shorter than those for crystalline silicon solar panels, meaning you could see a return on investment sooner. But they are less durable and have lower efficiency ratings, so you might have to purchase more panels to generate the same output.
The installation of crystalline silicon solar panels is similar to that of thin-film solar panels. In both cases, you’ll have to use hardware and mounting brackets to secure the solar panels to your structure. Additionally, you’ll have to install and connect an inverter to the grid, then make connections and wiring between the inverter and the panels.
Nevertheless, installing thin-film solar panels is typically easier and faster than installing crystalline silicon panels. That’s because thin-film panels are lighter, more flexible, and easier to handle. Plus, their thin profile means you don’t need many mounting brackets or too much labor.
The average lifespans of thin-film and crystalline silicon solar panels vary. Thin-film solar panels normally last 20-25 years; however, crystalline silicon solar panels can last up to 30-35 years. Various conditions, including weather, temperature, and installation, can impact both panels.
Very high temperatures can cause cells to disintegrate faster, whereas extremely low temperatures can make them less efficient at producing power. Moisture can also damage solar cells. Proper installation and maintenance are essential for ensuring a longer lifespan.
How to Choose the Right Solar Panel for Your Project
There are various varieties of solar panels, including polycrystalline, monocrystalline, and thin film. Each type has its pros and cons. Generally, when shopping for solar panels, keep in mind the following:
- Cost: Consider the cost of the solar panel as well as the installation fees.
- Efficiency: Examine the panel’s efficiency and capacity to convert light into power.
- Durability: Consider the solar panel’s lifespan and capacity to withstand various environmental factors.
- Maintenance: Consider the panel’s maintenance needs, such as cleaning and component replacement.
- Certifications: Scrutinize the panel’s certifications, which include UL, IEC, and ETL certifications.
- Warranty: Determine how much insurance the manufacturer is willing to place on your investment.
- Project’s requirements: Determine your project’s size, energy requirement, and space where the panel will be installed, as well as the local climate.

FAQs about Solar Panel
Yes, crystalline silicon solar panels can be recycled. The process involves breaking down the panels and separating the different materials, such as the glass, metal, and silicon. The recycled materials can then be used to create new solar panels or other products.
Thin-film solar panels are made by depositing one or more thin layers of photovoltaic material onto a substrate. This is typically done through a process called chemical vapor deposition, where the material is heated and evaporated before being deposited onto the substrate. Thin-film panels can be made from a variety of materials including amorphous silicon, cadmium telluride, and copper indium gallium selenide.
Advantages: Crystalline silicon solar panels are durable, long-lasting, and efficient at converting sunlight into electricity. They are also widely available and can be easily installed on roofs or other surfaces.
Disadvantages: Crystalline silicon solar panels are more expensive to produce than other types of solar panels, and their efficiency decreases in hot temperatures. They also require a significant amount of space for installation.
