Question 1

What Are Solar Panels?

Accepted Answer

In the 21st century, it has become essential to switch to alternate sources of energy. Solar power has emerged as a great source of energy for household use, offices, etc.

Solar panels, also referred to as photovoltaic (PV) panels, are the means by which light from the sun is converted. The light consists of energy particles known as “photons” that get converted into electricity.

A solar panel is made up of multiple solar cells. When several solar cells are spread across a large area, they can generate useable amounts of power.

The cells in PV panels are made of semi-conductive materials like silicon. They have both a positive layer and a negative layer, which create an electric field together.

Question 2

How Do Solar Panels Work?

Accepted Answer

When sunlight comes in contact with the semi-conductive material in the solar PV cell, the light energy gets absorbed in the form of photons. It loosens up several electrons that then freely float around in the cell.

Solar PV cells are carefully designed in a way that negatively and positively charged semi-conductors are squeezed together to form an electric field.

The field so formed compels the floating electrons to flow in a certain direction, specifically towards the conductive metal plates lining the cell. This flow is referred to as an energy current. The current's strength ascertains the amount of electricity each cell is capable of producing.

As soon as the free-floating electrons meet the metal plates, the current gets steered into wires, letting electrons move like they would in any source of electricity generation.

Question 3

How Long Does A Solar PV InstallationTake?

Accepted Answer

Before you decide on a provider, you can ask them for a quote and how long the entire process will take. The duration depends on the complexity and size of your solar panel system.

It takes a few weeks to get quotes and home visits from installers. But once you decide on a provider, the process will not take much longer.

As soon as the scaffolding is complete, the actual installation should be done within a day in the case of regular sized panels. However, bigger panels might take a more prolonged period.

Question 4

Are Solar Panels WorthIt?

Accepted Answer

To determine whether solar panels are worth it or not, you first need to understand that they are a long-term investment. Initially, it might be a little costly to install a solar panel system. However, the benefits will kick in gradually.

Yes, solar panels are worth it under certain conditions. If you generate a sufficient amount of energy and stay in the same house for a long time, you'll receive your money's worth.

Eventually, over the course of several years, solar panels pay for themselves.

Question 5

What Are Solar Panels Made Of?

Accepted Answer

Solar panels consist of multiple solar cells that work to absorb light from the sun and convert it into electricity.

Most solar PV panels use crystalline silicon wafers as the primary material. In fact, silicon is used to make semi-conductors from approximately 95% of all solar panels in the market. The other 5% depend on experimental technologies such as organic PV cells.

The semi-conductors are responsible for generating electricity. When they get in contact with sunlight, their electrons are knocked loose, creating electricity. This process is referred to as the photovoltaic effect.

The other components of PV cells include metal, glass, wiring, and plastic. A layer of glass is generally used to cover solar panels. Additionally, there is an anti-reflective coating for protecting the delicate silicon cells while still allowing light to pass through.

This entire framework is supported with plastic or polymer frames that are required for installation on both rooftop or ground-mounted solar panel systems.
