THEORY:Introduction to Solar Photovoltaic Panels ("PV")

The sun delivers its energy to us in two main forms: heat and light. There are two main types of solar power systems, namely, solar thermal systems that trap heat to warm up water, and solar PV systems that convert sunlight directly into electricity as shown below.

When the PV modules are exposed to sunlight, they generate direct current electricity. An inverter then converts the DC into alternating current (“AC”) electricity,
so that it can feed into one of the building’s AC distribution boards (“ACDB”) without
affecting the quality of power supply.

At this image is shown how PV modules are connected to the battery bank.The Charge controller is used as protection for overcharging and damaging the battery bank. The battery bank stores the excess power which later can be used as a power source when there is no sun or if there is bigger demand of power.

Solar PV Technology

A solar PV system is powered by many crystalline or thin film PV modules. Individual PV cells are interconnected to form a PV module. This takes the form of a panel for easy installation.

  

PV cells are made of light-sensitive semiconductor materials that use photons to dislodge
electrons to drive an electric current.

There are major groups of technologies used for PV modules: Mono and Poly Crystalline Cell  and newer one Thin film.



Below a "family tree" is shown which gives an overview of these technologies available today.

Introduction

First of all I want to introduce mu self, my name is Bale, I am young enthusiast and future electronics engineer(I hope that will be true very soon).I was always very interested of different ways of producing power(electrical or heating power). I'll use this blog as a small corner where everybody will be able to read and learn something about these technologies. If you are satisfied with the content on this blog, please share this blog to your friends. If you have any question or suggestion, please comment. Thanks!
