What is solar power?

The global energy industry now is witnessing a historic change. That is, the transition to renewable energy-a clean and never-ending source of energy. Solar power, also called Photovoltaics, has long been recognized as a renewable source of electric and thermal energy which is derived from the Sun. This is a technology that turns the energy from sunlight directly into electricity, or, to put it another way, into usable energy. Solar power has been proven to be the leading source of potential energy which can make a significant contribution to the future energy supply and demand by science and technology. In fact, solar photovoltaics are the fastest increasing source of power. In 2018, roughly 100 GW of global capacity was added, increasing the total to around 505 GW and providing a bit more than 2% of the world’s power.

Why solar power?

The key point that makes solar power solutions become the global future trend is that they are a sustainable, clean, and ecologically beneficial source of energy. It is also considered as an inexpensive energy source that can be harnessed virtually anywhere on the planet – any place where sunlight strikes the earth’s surface is a possible location for solar power generation. And, because solar energy is produced from the sun, it is an infinite supply of electricity. Furthermore, the process of converting energy from the Sun also helps to reduce a huge amount of carbon emissions which are generated during the burning of fossil fuels.

Assume that there is a 2-MW solar power system with the array’s service life of 25 years replacing coal and natural gas; when producing 67,500 MWh, a coal power station emits 67,500 tonnes of CO2 equivalent. This is 25 times higher than the total emissions produced by the above-mentioned solar array. In addition, the installation of solar power systems by individuals, organizations, and businesses and thereby mastering the energy source for the process of consumption, production, and business also contributes to reducing the load of the increasing pressure of energy shortages all around the world. There is an undeniable fact that oil, gas, and coal took hundreds of thousands of years to produce, so every time one of those finite resources is burnt to generate energy, that finite resource moves a little closer to exhaustion. Those are the reasons why the use of solar power is greatly encouraged worldwide.
