So, if you are also planning to shift towards the solar panels, then you must read this guide. This guide will illustrate the different types of 20w solar panels available in the market, their advantages and limitations, and prices as well.
Now, let’s dive into the details.
How Does A 20W Solar Panel Works?
Solar Panels are used to collect solar panels from the sunshine and convert them into electricity. The 20W solar panels are composed of individual solar cells. Also, they are made from a layer of phosphorus, silicon, and boron. The layer of Phosphorus provides a negative charge, the Boron layer provides a positive charge, and the silicon acts as a semiconductor.
So, when the photos of the Sun strike the panel’s surface, it knocks out the electrons from the silicon and other materials layers and into the electric field generated by the solar leads in a directional current. After that, it is harnessed into a usable power.
This whole procedure is called the photovoltaic effect, that’s why solar panels are also known as PV panels or photovoltaic panels.

There are various types of solar panels available in our Indian market depending on the solar panel watts. However, when it comes to 20W सोलर पेनॉल्स, there are only two types of panels available in the market.
- Monocrystalline Solar Panel
- Poly-crystalline Solar Panel
- Monocrystalline Solar Panel: The 20w Monocrystalline solar panels are also known as single crystalline silicon panels. These solar panels are made up of black solar cells in which the light of the panel interacts with a single crystal to generate electricity. This solar panel is highly efficient and generates a high power capacity compared to other panels. However, in India, these solar panels are more expensive than the other panels. But these panels are the best for businesses and houses that have space issues. More than 80% of the homes have installed 20w monocrystalline solar panels to save more money on electricity bills.
- Poly-crystalline Solar Panel: The 20w Poly-crystalline solar panel is another most used type of solar panel in India. This type of solar panel is known as a multi-crystalline solar panel. It contains a crystal fragment layer of silicon that dissolves before producing the silicon slices. Although these panels are less consistent in generating electricity in comparison to monocrystalline solar panels, these are less expensive and affordable. In addition, businesses and homeowners with large areas can go with the Polycrystalline solar panels as they are pocket-friendly.
Specifications of 20W Solar Panels
If you are planning to install the 20W Solar panels either for your business or home, then you must consider some specifications before purchasing the panels. So, while purchasing the 20W solar panel, you must check the following specifications:
