Solar power has gained so much attention in current times mostly because the source of energy use in daily household and business activities are becoming largely sustainable and cost-inefficient. Described below are some of the advantages the solar energy wields over many other sources of energy.
Solar energy is a renewable energy source. This means that we cannot run out of solar energy, as opposed to non-renewable energy sources (such as fossil fuels, coal and nuclear energies). Solar power is non-exhaustible because it can be used as long as the sun shines on & lives, without any fear of it being used up or over-exploited.
It is researched that the surface of the earth receives 120,000 terawatts of solar radiation (sunlight) which can generate 20,000 times more power than what is needed to supply the entire world with solar energy. Solar energy is available all over the world. Consequently, Solar energy is available anywhere the sun shines; its quality, however, varies according to location and climatic conditions. The areas closest to the equator have the highest solar radiance, but other zones far north and south from the equator can also exploit solar energy.
The abundant and renewable energy source is also sustainable. Sustainable energy sources meet the needs of the present without compromising the ability of future generations to meet their needs. In other words, solar energy is sustainable because there is no way it can be over-consumed.
Harnessing solar energy does generally cause pollution. The only pollution produced as a result, is only the construction or manufacturing of solar panels and its devices in the factory, their transportation & installation of solar power systems which is almost nothing compared to most conventional energy sources. The production of energy from the use of fossil and some renewable fuels (such as wind turbines) can be noisy, yet solar energy produces electricity very quietly. It is clear that solar energy reduces our dependence on non-renewable energy sources. This is an important means of sustaining the physical environment.
Solar panels can be installed on top of many rooftops or in a surface floor, which eliminates the problem of finding the required space for solar panel placement.
Various experiences indicate that the use of solar power leads to savings on utility bills. Research in the U.S. indicate that adding solar panels to the conventional electricity used can result in monthly savings of well above $150.00 to many users in many states in the US. In Hawaii for example, residents have the potential to save on average $64,000 after 15 years which could buy a house. If households and organizations in developed countries whose energy supply systems are efficient can save so much on energy consumption, then more can be saved by organizations and households in Africa whose energy supply systems is inefficient, unreliable and expensive. Even the cost of repairing our damaged household appliances due to power fluctuation and unnecessary high voltages. The cost resulting out of these poor electricity services are enormous.
