Types of solar panels for residential use
Are you considering transitioning to solar energy for your home? Would you like to learn about the different types of home solar panels available so you can make an informed decision?
In this article, we will explore the five most common types of home solar panels. By the end of this article, you will have a better understanding of which solar panels are most suitable for your home.
Here are the primary types of solar panels for home use:
- Monocrystalline Solar Panels
Also referred to as monosilicon, monocrystalline solar cells are produced from wafers cut from a single crystal. These cells are the most widely used for residential solar panel systems.
These cells offer the highest efficiency compared to other photovoltaic (PV) cells because they are made from high-grade silicon and have fewer impurities. These cells also provide a more uniform appearance because each cell is cut from a black cylindrical rod.
The drawback of this type of solar panel system is that it is more expensive than other types. These solar panels also require more space per watt because they need high-grade silicon material.
Monocrystalline solar systems are ideal for small roofs with limited space due to their high energy density. This means you can generate a lot of power with fewer panels. Their performance is also good in low light and high temperatures, which makes them appropriate for hot climates.
Structure: Comprised of a single crystal of pure silicon.
Efficiency: Highest efficiency among solar panel types (17-20%).
Appearance: Typically black or dark blue, with a consistent, sleek appearance.
Pros: Highest power output per unit area, longer lifespan, and better performance in low light conditions.
Cons: More expensive than other types.
- Polycrystalline Solar Panels
Polycrystalline cells are constructed from multiple crystals and can be distinguished by their bluish hue and square edges. They are less expensive than monocrystalline cells because they use lower-quality silicon, can be manufactured more rapidly, and have a simpler production process. However, they possess a lower efficiency rating than monocrystalline cells due to the existence of impurities in their crystal structure. This means they require more space per watt, making them more suitable for larger roofs.
These panels do not perform well in high-temperature conditions. Nevertheless, they do absorb light effectively, even on overcast days or in areas with limited sun exposure.
Structure: Comprised of multiple silicon crystals fused together.
Efficiency: Slightly less efficient than monocrystalline (15-17%).
Appearance: Often bluish-gray with a slightly textured look.
Pros: Lower cost than monocrystalline, but still provides good performance.
Cons: Slightly lower efficiency and lifespan than monocrystalline.
- Thin Film Solar Panels
Amorphous silicon thin film solar panels are produced through chemical vapor deposition (CVD). In this process, a thin layer of silicon is deposited on a substrate. The silicon absorbs a broad range of light to perform well in low-light conditions. While this type of solar cell can be very efficient, its efficiency decreases rapidly, and some panels lose efficiency over time. PowerFilm manufactures portable solar panels using this technology that utilize only a few watts.
Due to having a light-absorbing layer that is about 350 times smaller than traditional rigid solar panels, thin film solar cells are significantly more durable and are cheaper to manufacture. Thin film solar panels can be installed on a variety of surfaces, but are best suited for large open spaces and rooftops. In addition to rooftop applications, they are suitable for solar farms and streetlights. Additionally, thin film solar panels are light in weight and can be placed in various locations.
Structure: Composed of a thin layer of semiconductor material deposited on a substrate.
Efficiency: Lower efficiency than crystalline panels (8-14%).
Appearance: Can be flexible and come in a variety of colors, making them more visually appealing.
Pros: Lighter weight, more flexible, can be installed on unconventional surfaces (like curved roofs), lower cost.
Cons: Lower efficiency, shorter lifespan, and less heat resistance.
- Amorphous Silicon Solar Panels
What are amorphous solar panels? Their advantages and disadvantages. Amorphous solar panels are made up of amorphous silicon (a-Si or a-Si:H) solar cells, which are in the category of thin-film silicon, where one or more layers of photovoltaic material are deposited onto a substrate.
Some types of thin-film solar cells have great potential benefits. The word “amorphous” literally means shapeless, meaning the silicon material is not structured or crystallized at the molecular level, like many other types of silicon-based solar cells.
Most pocket calculators are powered by thin-film solar cells made from amorphous silicon. Because of the low output of amorphous solar panels, they are only used for low-power equipment.
Structure: A type of thin-film solar panel made from amorphous silicon.
