Imagine watching your favorite TV show and the light went off as predicted, so you kicked your generator and it was not coming up, out of frustration you tried several times and finally the coil exploded….…..  Yes just as i imagined. Nothing can be more annoying than failure in power supply when you have something really important at your disposal.

The need for power cannot be over emphasized in the day to day activities.  The number of people and organization relying on electricity for survival increases daily and no matter the government attempt they have been unable to solve the problem of power supply failure.

Now the need for individuals and organizations to have alternative sources of power for the continuity of their day to day activities arises. One of the various sources of power that generates enough power is the ‘Solar Energy’

Solar power is the conversion of energy from sunlight into electricity, either directly using photovoltaic (PV), or indirectly using concentrated solar power. It is the technology used to harness the sun’s energy and make it usable.


Solar energy a Large beams of sunlight that focuses on a small beam using mirrors or lenses in the case of concentrated solar power. Photoelectric effect is used by Photo voltaic to convert solar energy into electric energy.

  • Solar energy does not produce any pollutants and is one of the cleanest sources of energy. It is a renewable source of energy that requires low maintenance and is easy to install. This source of energy never runs dry because it is a completely free source of energy and it is found in abundance.


  • Solar power is noise pollution free. It has no moving parts, and does not require any additional fuel, other than sunlight, to produce power.


  • Solar panels are virtually maintenance free since the batteries require no water or other regular service and will last for years. Once, solar panels are installed, there are no recurring costs.

  • A home solar panel system consists of several solar panels, an inverter, a battery, a charge regulator, wiring, and support materials. Sunlight is absorbed by the solar panels and is converted to electricity by the installed system. The battery stores electricity that can be used at a later time, like cloudy days or during the evening.

Solar energy however does not work on its own without the use of a solar panel and an inverter.

An inverter is an electrical device that converts direct current (DC) to alternating current (AC), and this alternated power can be maintained in any frequency or voltage with the use of appropriate transformers, circuits and switches.

There are different types of inverter. Stated below are the main types of inverter.

  • Pure Sine wave inverter produces a multiple step sinusoidal AC waveform. sine wave inverter output waveform is good, low distortion, low interference to radio and equipments, low noise and in addition, high efficiency, suitable for use in the communications, industrial electricity by enterprises and other users.
  • Square wave inverter is one of the simplest waveforms an inverter design can produce and is best suited to low-sensitivity applications such as lighting and heating. Square wave output can produce “humming” when connected to audio equipment and is generally unsuitable for sensitive electronics.
  • Modified sine wave inverter is a type of home inverter obtains power from a battery of 12 volts and must be recharged using a generator or a solar panel. Appliances like microwave ovens, light bulbs, etc. can be run using these types of inverter. They provide enough power for the normal home requirement and are the most affordable.


Solar Panel is a panel designed to absorb the sun’s rays as a source of energy for generating electricity or heating. The solar panel is used to collect solar energy during daytime and used at the time of need after being converted into electrical energy. Lots of small solar cells spread over a large area can work together to provide enough power to be useful.

The more the light that hits a cell, the more electricity it produces, so spacecraft are usually designed with solar panels that can always be pointed at the Sun even as the rest of the body of the spacecraft moves around, much as a tank turret can be aimed independently of where the tank is going.

Today solar energy is one of the most essential household appliances when power is interrupted.

Though solar energy only provides a small fraction of the world’s energy supply it is used on a wide scale and despite the drawbacks, solar energy use has surged at about 20 percent a year over the past 15 years due to the failure of power supply.

Battery: This is needed for saving the absorbed power from the sun through the solar panel or generator. With solar batteries, you maximize your ability to use the electricity generated by your solar panels on a day-to-day basis. During the times when you need more electricity than your solar panels are producing (later in the day or at nighttime), you can use the solar energy you have stored.

Charge controller: Solar charge controllers regulate the energy flowing from the PV array and transfer it directly to the batteries as a DC-coupled system, which is the most efficient and effective manner. Giving batteries as long of a life as possible is an important function of a charge controller.
