Solar Panel Basics

Solar panels are devices that convert sunlight into electricity. They are an eco-friendly, renewable energy source used by businesses and homes worldwide. Solar panels have gained in popularity due to their ability to reduce dependence on nonrenewable resources, lower energy bills, and minimize greenhouse gas emissions. This section will explore the basics of solar panels, including the types of solar panels, how they work, and their benefits.

Types of Solar Panels

There are three main types of solar panels available in the market. They are:

  1. Monocrystalline Solar Panels: These solar panels are made from a single crystal structure, known as a monocrystalline silicon ingot. As a result, they have a high efficiency rate (typically around 20-23%). Monocrystalline solar panels are easily recognizable by their uniform dark black color. They also perform well in low light conditions and require less space for installation. However, these high-efficiency panels come at a higher price compared to the other types of solar panels.

  2. Polycrystalline Solar Panels: These solar panels are made from several fragments of silicon crystals, which are melted and then molded into a panel. Because of this, the efficiency rate is slightly lower, usually around 15-17%. The appearance of polycrystalline solar panels is blue with a speckled pattern. Although they are less efficient than monocrystalline solar panels, they are also less expensive and a popular choice among homeowners looking for a budget-friendly option.

  3. Thin-Film Solar Panels: As the name suggests, thin-film solar panels are much thinner compared to monocrystalline and polycrystalline panels. They are made by depositing a thin layer of semiconducting materials, such as amorphous silicon (a-Si), copper indium gallium selenide (CIGS), or Cadmium Telluride (CdTe), onto a substrate. Thin-film solar panels have a lower efficiency rate, usually around 10-12%. However, they are lightweight, flexible, and can be used for various applications like building-integrated photovoltaics (BIPV), where solar panels are integrated into windows, walls, or rooftops. Thin-film solar panels are less expensive than monocrystalline and polycrystalline panels, but their lower efficiency requires more space for installation.

How Solar Panels Work

Solar panels work by utilizing the photovoltaic (PV) effect: when sunlight (photons) hits the solar panel, it causes the electrons in the solar cells’ semiconducting material to become excited and move freely. This creates an electric field and thus generates an electric current—also known as direct current (DC).

A solar power system consists of several components besides the solar panels, such as inverters, mounting hardware, and a balance of system (BOS) components like wiring, switches, and controllers. The DC electricity generated by the solar panels is converted to alternating current (AC) by an inverter, which is then used to power your home or be fed into the electricity grid.

Solar Panel Components

Solar panels, also known as photovoltaic (PV) modules, are devices that convert sunlight into electricity. They are made up of several components, each with a specific function to ensure the efficient conversion of sunlight into usable electricity. In this section, we will discuss the main components of a solar panel, including solar cells, backsheet, frame, junction box, encapsulant, and anti-reflective coating.

Solar Cells

Solar cells are the most crucial component of solar panels, as they are responsible for converting sunlight into electrical energy. A solar cell is typically made of silicon, which is a semiconductor material. There are two types of solar cells: monocrystalline and polycrystalline. Monocrystalline solar cells are created from a single crystal of silicon, making them more efficient and expensive, while polycrystalline solar cells are made from several silicon crystals and are generally cheaper, with slightly lower efficiency.

When sunlight strikes the solar cell, it knocks electrons loose from the silicon atoms, creating a flow of electricity. To optimize the flow of electricity, the solar cells are connected in series and parallel circuits. Series connections increase the voltage, while parallel connections increase the current. The amount of power a solar panel can generate depends on the efficiency and the number of solar cells used.


The backsheet is the protective layer located at the back of a solar panel. It serves several functions, including providing electrical insulation, protecting the solar cells from external elements, and ensuring the overall durability of the solar panel. The backsheet is typically made of plastic materials, such as polyvinyl fluoride (PVF) or polyethylene terephthalate (PET), that are resistant to ultraviolet (UV) radiation, moisture, and high temperatures.

A high-quality backsheet is crucial for the overall performance and longevity of the solar panel, as it helps prevent potential issues, such as delamination, corrosion, and short-circuiting, that can significantly reduce the efficiency of the solar panel or even lead to complete failure.


The frame is another essential component of a solar panel, as it provides structural support and protection for the panel. The frame is usually made of anodized aluminum, which offers durability, lightweight, and resistance to corrosion. The frame design should ensure proper water drainage and ventilation to prevent moisture build-up and promote optimal panel performance.

Additionally, the frame should have pre-drilled holes or mounting brackets for easy installation of the solar panel. The frame design may vary depending on whether the solar panel is intended for residential, commercial, or utility-scale applications, as well as on the type of mounting system used, such as roof-mounted or ground-mounted installations.

Junction Box

The junction box is a small, protective component located at the back of the solar panel, which serves as a connection point for the panel’s electrical wires. It contains vital components, such as bypass diodes and terminals, that help regulate the electrical output of the solar panel and prevent power loss due to shading or malfunction of individual solar cells.

Bypass diodes are essential for preventing hot spots and enhancing the overall performance of the solar panel when its solar cells are partially shaded. They essentially create a “bypass” for the electrical current, allowing it to flow around the shaded or non-functioning cells, rather than through them. In this way, the junction box contributes to the overall safety and efficiency of the solar panel system.


The encapsulant is a transparent, adhesive material that is used to bond the solar cells, backsheet, and the front glass layer of the solar panel. The encapsulant serves several crucial functions, including providing mechanical support for the solar cells, protecting the solar cells from moisture and other external elements, and ensuring optimal light transmission. The most commonly used encapsulant material is ethylene-vinyl acetate (EVA), which offers high transparency, excellent adhesive properties, and resistance to UV radiation and extreme temperatures.

A properly selected and applied encapsulant ensures the long-term performance of the solar panel by preventing potential issues, such as delamination, degradation of solar cells, and loss of adhesion, which can all adversely affect the efficiency and reliability of the panel.

Anti-reflective Coating

The anti-reflective coating is applied to the front glass layer of the solar panel to increase light transmission and enhance the overall efficiency of the panel. By reducing the amount of light reflected off the surface of the glass, the anti-reflective coating allows for greater sunlight absorption by the solar cells. This results in a higher power output for the solar panel.

Common materials used for anti-reflective coating include magnesium fluoride (MgF2) and silicon nitride (SiN), which offer excellent anti-reflective properties, resistance to UV radiation, and durability. The application of an effective anti-reflective coating is crucial to ensuring the optimal performance and longevity of a solar panel.
