Photovoltaic vs Solar Panels

In 1759, Benjamin Franklin discovered electricity by noting its presence in lightening. Since then, a variety of methods used in generating electrical currents has surged through the process of time. The most common way in which electricity is generated is through fossil fuels and crude oil, amongst others.

Fuels are efficient enough to produce high outputs but they cost the environment much of its ambiance. They deplete the atmosphere by submerging it into the calamitous occurrence of climate change. To make things safer, therefore, and environmentally friendly, scientists have discovered other sources of electricity. One of these is solar energy.

Solar energy is the light and heat from the sun captured and redirected by a host of other means, such as solar thermal, solar panels, and concentrated solar power (CSP), for generating power. It is a safe way to breed electricity, it does not involve the release of carbon emissions into the atmosphere.

However, this essay tends to look at the synchrony that reclines between photovoltaic cells and solar panels. It is to observe how the two work together to produce electricity and further the narrative of a safe and clean environment.

Energy, in simple terms, is the ability to do work. The insatiable desire to do work beyond human disposition has led to the discovery of various types — kinetic, potential, nuclear, electrical, gravitational, solar, etc. — of energy used to carry out daily human functions and even more. Notwithstanding, some of these energies are hard to get, some are detrimental to the environment. The exploitation of solar energy, however, has come to bear good fruits.

As mentioned earlier solar energy is the use of light and heat from the sun to generate power. Now there are different kinds of solar technology that produce electricity in different ways like the solar thermal that encapsulates heat and converts it into electricity, or the concentrated solar power (CSP) that consolidates power using mirrors and lenses onto a receiver. There is also the quick eco-friendly solar panel that makes use of photovoltaic (PV) cells in electricity generation.

Scientists have now invested much of their time in producing thinner PV cells that will permit the acceptance of solar technology in airplanes, buildings and constructions, and ubiquitous use for everyday home appliances. This will dispel the intermittent use of solar panels as only large square pavements/boards affixed on rooftops of houses and industries.

How does a solar panel work? Photovoltaic cells and solar panels work together in the art of generating electricity for everyday use.

In 1839, nearly a century after electricity had been discovered, Edmond Becquerel, a French Physicist discovered the principle that guides the use of PV power. The principle states that when electrons are disoriented, electric current occurs when light particles elate the outermost electrons of the semiconductor

Many PV cells are linked together to make up a solar panel. A semiconductor, usually silicon stands as the impetus for the working solar panel. PV cells are made up of two slices of silicon (semiconductor). They generate electricity through a process called photoelectric effect and solar radiation.

This is how it works. With the help of the semiconductor, PV cells generate and harness electricity immediately it comes in contact with light. It uses energy from the sun to power appliances.

PV is a special kind of cell as it only requires daylight to generate energy. Explicitly, even when there is no direct sunlight, like on a cloudy day, PV cells are able to generate electricity as long as the panel is placed on the rooftop of a building with no shadow hovering across it.

However, the amount of power output and flow within PV cells depends on the intensity of sunlight. More sunlight gives off greater output while less sunlight gives off lesser output. As compared to other types of producers, solar panels are low cost; financial and maintenance wise. They are more ozone layer friendly. They produce no greenhouse effects, therefore cutting back on tons of carbon dioxide. They are the best type of electric current generator to be used as a supplement for fossil fuels and crude oil.

Incorporating PV solar panels can help in reducing greenhouse emissions from wreaking havoc on our environment. A viable substitute for fossil fuels and an intelligent way of utilizing sunlight, a never-ending resource for power generation. It is less wasteful and looks promising for industries that contribute largely to the production of carbon emissions.

Photovoltaic cells and solar panels can be described as the next top generator of electricity if more effort is put into producing better versions of the ones that already sweep through energy markets. In the coming yearsPhotovoltaic vs Solar Panels, the idea of sun-powered cars and planes will materialize.
