Photovoltaic energy is a type of energy that comes from the sun. It’s a renewable and clean source of energy.

1. Basics of Photovoltaic Energy
Photovoltaic energy is the conversion of sunlight into electrical energy.
The word "photovoltaic" is derived from the Greek words "photon" and "voltaics."
Photons are tiny packets of light that carry energy and are emitted by the sun. When a photon enters a photovoltaic cell, it creates an electric potential across its surface. The electric potential causes electrons to move from one side of the cell to the other. This movement produces a current, which can be used to make electricity.
The process of converting sunlight into electricity is called photovoltaics (PV). Photons convert directly into electricity through PV cells, which convert light into direct current (DC) electricity.
There are two types of PV cells:
- Solar cells: These cells absorb photons and produce DC electricity when exposed to sunlight or any other source of light that generates enough photons to create an electric potential across their surface. They are used in solar panels, space satellites and some portable electronic devices such as calculators, watches and pagers.
- Photo voltaic cells: These cells generate DC electricity by converting photons into electrons in the presence of an electron-rich material called a semiconductor material or semiconductor device. They are used in home solar systems, which provide DC power for appliances such as lights and small appliances such as refrigerators and air conditioners when connected with wiring to a central inverter unit that converts DC power to AC power for use in your home’s electrical system.
2. What are Photovoltaic Panels?
2. What are Photovoltaic Panels?
Photovoltaic (PV) panels are solar panels that convert the sun’s rays into electricity. These panels consist of a semiconductor, which is a material that produces electrical current when it absorbs sunlight. The semiconductor is coated with a transparent conductive oxide film, which enables the electricity to flow through the material.
What are photovoltaic panels?
Photovoltaic (PV) panels produce electricity from the sun’s rays by converting solar energy into direct current (DC). Solar cells are made up of two layers of PV cells, which are connected in series to create a single solar cell. The solar cell is attached to a junction box that collects and converts DC power into AC power and connects to an inverter.
Types of photovoltaic panels
There are three main types of PV panels: monocrystalline, polycrystalline and thin-film modules. Monocrystalline modules contain silicon wafers that have been grown using chemical vapor deposition (CVD) technology, while polycrystalline modules contain silicon wafers that have been grown using the float-zone process. Thin-film modules contain very thin layers of various materials such as cadmium telluride or amorphous silicon, instead of silicon wafers as in monocrystalline and polycrystalline modules.
3. Where to Buy Photovoltaic Panels?

Photovoltaic energy is the use of solar energy to create electricity. The technology is often referred to as solar power, and it’s a renewable source of energy.
Solar panels use the sun’s energy to convert sunlight into electricity. Photovoltaic systems can be installed on rooftops or on the ground, and they are commonly used in remote areas where there is no access to electrical power.
Where to buy photovoltaic panels?
The good news is that you don’t have to go to a store and purchase a photovoltaic panel. You can buy them online or directly from the manufacturer. The following companies sell both residential and commercial photovoltaic systems:
- SolarCity
- SunPower
- Sungevity
- Sunrun
