Different Types Of Solar Panels Explained: Introduction To The Types Of Solar Panels And Brief Description

There are various types of Solar Panels available in the market and all the different types have their own advantage. Understanding the different types of solar panels is essential for anyone considering solar energy for their home or business. Here we are going to understand all types from traditional crystalline silicon panels to innovative thin-film. So let’s dive in the world of solar panels and get understood about the new generation energy power plant.

Different Types Of Solar Panels:

The solar panels can be divided in 7 types;
  1. Monocrystalline Silicon Solar Panels
  2. Polycrystalline Silicon Solar Panels
  3. Thin-Film Solar Panels
  4. Bifacial Solar Panels
  5. Concentrated Solar Power (CSP) Panels
  6. Building-Integrated Photovoltaics (BIPV)
  7. Organic Photovoltaic (OPV) Panels

1. Monocrystalline Silicon Solar Panels:

Monocrystalline Silicon Solar Panels

These panels are made from a single crystal structure and have a high energy conversion efficiency. They are easily recognizable by their uniform black color and rounded edges. These panels are type photovoltaic(PV) and known for it’s high efficiency and sleek black appearance. The silicon used in these panels is grown as a large cylindrical ingot, which is then sliced into thin wafers. The wafers have a uniform dark color and a smooth texture.

2. Polycrystalline Silicon Solar Panels: 

Polycrystalline Silicon Solar Panels

These panels are also known as also known as multi-crystalline silicon solar panels. That is also one type of photovoltaic(PV) panels. These panels are made of multiple silicon crystals, that’s why it is known as “Polycrystallin”. The silicon used in these panels is also melted and formed into ingots, but the cooling process is faster, resulting in multiple small crystals forming within the panel. This gives the panel a textured, speckled blue appearance. Efficiency of these panels is typically ranges from 13% to 16%, meaning they can convert around 13% to 16% of the sunlight that hits them into usable electricity.

3. Thin-Film Solar Panels: 

Thin-Film Solar Panels

These panels are also known as Thin film photovoltaic. These panels are made by depositing one or more layers of semiconductor material on any subtract like glass, plastic or metal. Thin film solar panels generally have lower efficiency compared to traditional crystalline silicon panels (both monocrystalline and polycrystalline). One of the main advantages of thin film solar panels is their flexibility. The use of lightweight and flexible substrates allows for the creation of flexible and semi-transparent solar panels. This flexibility enables their integration into various surfaces, including curved structures and building materials.

4. Bifacial Solar Panel: 

Bifacial Solar Panel

As it’s name describes, this type of solar panel can generate energy from both the sides. Bifacial solar panels have a similar structure to traditional monofacial solar panels. They typically consist of a layer of semiconductor material, such as crystalline silicon, sandwiched between a front glass cover and a rear glass or transparent back sheet. There is the transparent backsheet which allows the solar panel the convert the sun light in energy from both the sides. Bifacial solar panels generates more energy in comparison to other solar panels due to the additional light absorption.

5. Concentrated Solar Power (CSP) Panels:

Concentrated Solar Power (CSP) Panels

This is a technology that uses lenses and mirrors to concentrate the sunlight on a receiver. After that the receiver the sunlight in heat or electricity. There are different types of CSP technologies, including parabolic troughs, power towers, linear Fresnel reflectors, and dish Stirling systems. Each uses a different method to concentrate sunlight onto a receiver. The concentrated sunlight is directed to a receiver that can be a pipe or a tower and the receiver contains a fluid like oil or other thing that gets heat up. This heat is used to produce steam or can be used directly in industrial use. To generate electricity the heat is used to drive a turbine that is connected to generator.

6. Building-Integrated Photovoltaics (BIPV) Solar Panels: 

Building-Integrated Photovoltaics (BIPV) Solar Panels

Building-Integrated Photovoltaics (BIPV) refers to the integration of solar panels into the building envelope, such as roofs, facades, windows, and canopies, where they serve as both functional building elements and electricity generators. BIPV solar panels offer a combination of renewable energy generation and architectural aesthetics. 

BIPV solar panels are designed to seamlessly blend with various building materials, such as glass, tiles, cladding, and roofing materials. BIPV solar panels function as electricity generators, converting sunlight into usable electrical energy. While the efficiency of BIPV panels may be slightly lower compared to traditional rooftop solar panels, their advantage lies in their dual functionality as both building materials and energy generators.

7. Organic Photovoltaic (OPV) Solar Panels: 

Organic Photovoltaic (OPV) Solar Panels

These panels are also known as organic solar cells, are a type of photovoltaic technology that utilizes organic materials to convert sunlight into electricity. Unlike traditional solar panels that use inorganic semiconductors like silicon, OPV panels employ organic molecules or polymers as the active material. OPV panels consist of thin layers of organic materials sandwiched between electrodes. The active layer typically contains organic semiconducting materials that can absorb photons from sunlight and generate electric charges. 

The electrodes, usually made of transparent conductive materials like indium tin oxide (ITO), allow for the extraction of the generated electrical current. The active layer in OPV panels consists of organic materials, such as polymers, small molecules, or a combination of both. OPV panels can be engineered to absorb a broader spectrum of light compared to silicon-based solar panels. This means that OPV panels can generate electricity from a wider range of sunlight, including indoor lighting or diffused light conditions.

The world is moving towards the solar energy and the Tesla Powerwall is one of the great step to generate the energy and use it for residential use.
