What is really a photovoltaic system and how does it work?
A photovoltaic (PV) panel, commonly called a solar panel, contains PV cells that absorb the sun's light and convert solar energy into electricity. These cells, made of a semiconductor that transmits energy (such as silicon), are strung together to make a module. A typical rooftop solar panel has 30 modules. When the semiconductor in the photovoltaic panels absorbs the sunlight, this knocks the electrons (which form the basis of electricity) free from their place, and they can now flow through the semiconductor. These dislodged electrons, each carrying a negative charge, flow over the cell toward the leading surface, creating an imbalance in control between leading and the back. Photovoltaic cells produce electricity because this imbalance, subsequently, creates a voltage potential such as the negative and positive terminals of a battery.
The current is then collected on wires and then used immediately or stored in a battery of the photovoltaic system. It's not the case that solar panels only work when sunlight is shining. However they won't generate just as much power on a cloudy day as on a warm one.
The φωτοβολταιϊκά συστήματα or solar PV system is really a technology developed to transform the power from the sun's rays into electricity through solar panels.
This technology is eco-friendly, safe to make use of, and generates green energy without causing pollution. A photovoltaic system comes in various sizes and is advantageous in solar water heating, ventilation, lighting, and transportation.
The first photovoltaic cell was discovered in 1954 by Gerald Pearson, Daryl Chaplin, and Calvin Souther Fuller. Since that time, it has been a satisfactory replacement and a solution to the depletion of fossil fuels. Today, it has changed into a vital source of energy for recharging devices.
Types Of Solar PV Systems
You will find three common kinds of solar PV systems: grid-connected, hybrid, and off-grid.
These PV solar panels supply electricity to customers by converting the sun's energy into solar energy using different techniques.
Grid-connected solar photovoltaic systems: Also called the utility-interactive PV system, this photovoltaic module runs on the basic grid-tied inverter. It generally does not require a battery to operate and has essential components. It transforms PV solar energy into AC power through the inverter. It's a functional solar PV module that reduces the entire electricity consumption.
Hybrid solar photovoltaic systems: These PV modules are an altered version of a grid-tied system and contain a battery backup. It's integrated with diesel generators and converts energy to AC or DC voltage.
Off-grid solar photovoltaic systems: It is an ideal device for people who cannot use grid-connected solar photovoltaic systems due to geographical restrictions or high costs.
It is known as a stand-alone PV system because of its efficiency in standing independently of the ability grid. The battery stores the PV solar energy for later use.
