Countries that are spending less on energy are the ones that have embraced the use of renewable resources. The sources for this power include solar, water, wind, geothermal, and biomass. This group also referred to as green energy is unlimited and costs less than the conventional one.
Some countries across the globe have embraced the usage of this energy. Among them is the United States, Denmark, Costa Rica, Germany, and Uruguay among others. One of the forms of energy that has become a sensation is solar power. It has been referred in many instances as a cheap source of energy.
Dynamics surrounding solar power
The sun is offered free of charge which makes this form of energy more affordable. Also, accessing power from the source is more economical than when a local power plant is involved. Solar power is currently being used in many countries to light up homes and businesses. This energy is harnessed when solar-powered photovoltaic panels convert sun rays into electricity.
With solar systems, solar panels are put on the roof in places with no shade especially during the prime hours of the day. During installation, possible factors that would cause shading are evaluated and removed as they work to reduce power production. In solar panels, when one of the 36 cells is obstructed, power reduction is experienced significantly.
Since people began utilizing solar energy, numerous technologies using solar radiation have been developed. Numerous solar power plants have been set up in various places. These facilities convert sun to electricity with the use of photovoltaics. The United States tops the charts followed by China and Spain in the utilization of solar power. America has the largest power station in California called the Topaz Solar Farm which has been operational since 2014.
More people are being drawn to solar power as it saves on the utility bill. The dynamics surrounding this source of energy and its practical uses is simple. Usage of this power not only cuts costs but is also safe for the environment given the current carbon footprint and the effects of non-renewable energy. In the coming years, combustion of fossil fuel will not be welcomed as the world is looking to adopt cleaner and affordable energy source.
The composition of solar panels and uses
But, how are solar panels made? They are comprised of silicon cells, metal frame, standard 12V wire, Plexiglas, and bus wire. The primary material used to make these panels is silicon cells. This material exists in three structures the amorphous, single cell, and the polycrystalline forms. The single cell also known as the monocrystalline forms as the most common in many panels.
The conductive properties of this nonmetal compound give it the ability to convert sunlight to electricity. Although, silicon does not work independently. It has to be joined with some metal casing accompanied by wiring to power the desired place. Although, not all roofs are designed for installation of solar panels. With these roofs, panels are placed in certain angles to trap the light.
Solar energy has multiple uses. It is being harnessed for cooking, heating buildings, making water hot, and generating electricity which is used to power engines. Water heating is enabled by the solar heater and saves on the electricity bill. The solar heater has two systems of heating. One is the liquid system that works as an antifreeze solution, and the other is an air-based collector. Currently, people are utilizing solar cooking as it is environment-friendly and inexpensive.
Solar cooking has become a thing in areas where deforestation is a huge issue, and there are limited resources to buy fuel. With this solution, mirrors are used to trap the sun rays. Solar cells have also become common among users. They work to supplement electric power from the grid system, particularly in remote areas. Energy produced by solar cells is also stored in rechargeable batteries to be used at a later time.
