How to plan a PV installation?

Surface Area: The surface area of the site at which the PV installation is intended should be known, to have an estimation of the size and number of panels required to generate the required power output for the load. This also helps to plan the installation of inverter, converts, and battery banks.

How does a PV system work?

A PV system works in a remarkably simple and efficient way. When sunlight hits the solar cells in a PV system, it excites the electrons in the cells and generates a flow of electric current. This process is known as the photovoltaic effect. Each solar cell is a small sandwich of semi-conductive material, typically silicon.

How do you know if a solar panel is octagonal?

If you have solar panels installed nearby, go there and look closely at them. You will notice each panel consists of several small rectangular or octagonal units. These units are nothing but solar cells. A solar panel consists of numerous solar cells. Solar cells are the engine of the photovoltaic system.

How do photovoltaic cells work?

To grasp how photovoltaic cells work, it’s key to understand the solar cell principle. This principle centers on the photovoltaic effect, where light becomes electrical energy at an atomic scale. Thanks to semiconductor technology, especially silicon, we can turn sunlight into electricity, heralding a promising renewable energy source.

What determines the efficiency of a solar panel?

The efficiency of a solar panel—that is, its ability to convert sunlight into electricity—is determined by several factors, including the quality of the silicon used, the configuration of the solar cells, and the panel’s exposure to sunlight. The silicon used in solar cells is the foundation of their efficiency.

What is photovoltaic effect?

This interaction between sunlight and solar cells is termed the photovoltaic effect. The phenomenon was discovered by Edmond Becquerel in 1839. When we close the circuit by connecting the upper and rear end of the solar cell, the excited electrons flow into the circuit. The diagram below depicts the same. Simple working of a solar cell
