Solar energy basically refers to the energy derived from the sun and converted into thermal or electrical energy. It is a power form that utilizes the energies of the sun. In more technical terms, solar energy is both light and heat from the sun harnessed using a range of ever-evolving technologies. 

It is one  among the many forms of energy that are classified as renewable energy. This is because  they are generated from replaceable and theoretically inexhaustible supply sources. 


Other forms of renewable energy include; 

  1. WIND ENERGY: This is the energy created by the use of wind turbines- a device that channels the power of the wind to generate electricity. 

  2. HYDROELECTRICITY: Electricity derived from the power of water in motion. This is a preferred energy source in areas with heavy rainfall and mountainous heights. 

  3. KINETIC ENERGY: The form of energy that an object derives by reason of its motion is known as kinetic energy. It could be motion energy from either rotational or vibrational frequencies. 

Among all the renewable energy sources outlined above, solar energy is increasingly becoming more attractive as the dominant renewable energy source of the 21st century. This is because the amount of energy that radiates from the sun is vastly in excess of the world's current and anticipated energy requirements. 


It is no wonder then that responsive energy service organizations like DGIS Solar Energy Services have seen it fit to harness the opportunities offered by the abundant supply sources of solar energy to empower millions of Nigerians through the ongoing solar energy and CCTV installations training packages.


As a reminder,  DGIS Solar Energy Services in partnership with Nigeria Society of Engineers, Owerri branch,  invites you to a detailed online training that qualifies you as a solar energy and/ or CCTV installations professional. This two months online training which offers a  90% discount from the original price starts on Monday 29th June, 2020. Please visit the web:  to fill and submit your online application form. 




Solar energy systems work when sunlight hits on a Solar panel (otherwise known as photovoltaic or PV module) to trigger the flow of electric current. The current produced from the PV panel is regulated and controlled by an arrangement of inverters, batteries, solar charge controllers etc. The inverter in turn converts direct current (DC)  into alternating current (AC).  It is the alternating current  (AC) that is needed for use in appliances for industries,  households and offices.




Solar panel is an electrical device consisting of a large array of connected solar cells. The panel itself is primarily made from silicon amidst several steps and processes. 


Silicon is a non-metallic chemical element in the carbon family that makes up 28% of the earth's crust. In a combined state, silicon is found in mineral deposits such as  rocks and sand. To convert sand or silicon to solar, it is purified using a heating separator, slicing the pure silicon and layering it to conduct electricity with  special anti-reflective slabs assembled in frames that can hold between 60 to 72 cells. 


 The PV cell is the building block of any solar panel. Whereas solar panels are made up of six different components,  the photovoltaic (PV) cell is the most outstanding among them all because it actually generates electricity by converting the sunlight  that hits on the solar panel into electrical energy. It is this conversion by a solar cell that is known as the "photovoltaic effect" of solar energy systems . And for this reason, solar cells are said to be "photovoltaic ".

A PV cell therefore could be defined as a solar cell, an electrical device or an energy harvesting technology that converts solar energy into useful electricity through the photovoltaic effect. 


A PV effect on its own is a combination of both physical and chemical phenomena that generates electric current in a PV cell when it is exposed to sunlight.




As the solar panel faces the sun, light particles called "photons" excite or send alert signals to silicon atoms on the solar panel. This alert triggers or knocks out electrons from the silicon and this reaction generates electricity. 


Photons are minute energy packets of electromagnetic radiation and the basic unit of all light. They are the elementary particles of light that first hit the solar panel as they are emitted from sunlight.



It might interest you to know that solar panels are made up of many smaller photovoltaic cells. In other words,  many solar cells link together to make up a solar panel. 

There are other types of solar power technology. These include solar thermal,  and concentrated solar power (CSP), although the way they operate differ from how the PV solar panel system functions. It is interesting to note however that all the solar systems we’ve mentioned harness the power of sunlight to generate electricity.
