Essay Sample on Solar Energy

Solar energy is harnessed from the radiant power produced by the sun’s rays. The radiant energy is converted into electrical current. Modern technology has increased the ability to harness and utilize solar energy. This has led to a shift from using conventional means to generate power to renewable sources of energy. Research has led to the development of cost effective means of capturing and storing solar energy.

The invention of solar panels and batteries enhanced the harnessing and storage of solar power. Solar panels are used to collect radiant energy. Consequently, the energy is stored in the batteries. The stored energy can be used to run home appliances and in the operation of machinery. At night, radiant energy is not available. Therefore, excess solar power stored in batteries is used to power home appliances and machinery.

There are two techniques used to generate electricity from solar power. The first method uses photovoltaic solar panels. These solar panels generate electricity directly from the sunlight. The second method is concentrating solar power. The method converts sunlight into heat to generate steam. As a result, electricity is generated by feeding vapor in a steam turbine.

Furthermore, solar energy is used to operate water heaters. Innovation in engineering has led to the emergence of a hybrid power system. In such a system, solar energy is jointly used with the traditional power. The system is vital in saving power bills and providing back up power in the event of failure of the local power gridiron.

Solar energy systems are relatively cheaper to install. This is in comparison to the high cost of installing conventional power systems. Furthermore, solar energy is affordable and efficient to households and businesses. This is the reason why solar energy is more appealing to most households. Similarly, business owners have significantly adopted its use.
