Just about everyone has seen or made use of a calculator which uses solar energy and we understand precisely how convenient they can be. There is no need for replacement batteries and they seem to go on indefinitely, so long as there is adequate light.
Maybe you have also observed the always growing use of solar panels in larger sized units, such as emergency road signs, telephone boxes and lighting for car parking bays. More and more of these convenient products are being powered by the sun rather than relying upon the more traditional forms of electricity.
So, you ask: How do these things work?
The answer is photovoltaics. This technology has been around since the late 1950s and was used primarily in space, powering the electrical devices in satellites. Presently, the technology is used in more run of the mill applications. Some individuals believe that the power of the sun will one day be harnessed to operate effective motor vehicles and that all of our energy needs will be without cost.
Photovoltaic panels, also known as pv panels, generate electricity as a result of the conversion of solar radiation into direct current (dc) electricity making use of semiconductors. This direct current is what we get through mains or grid power. An inverter is needed to change dc power to ac, which is the sort of electricity utilised for such applications as boats, electric cars and roadside emergency telephones.
Each of these solar pv panels have a quantity of cells and these cells in turn contain photovoltaic material. The most generally applied materials are composed of silicon. This material must be protected from the elements: usually this means it is crammed snugly behind a sheet of glass. For situations where a significantly greater quantity of electrical power is necessary, the panels are hooked up in arrays.
In just a decade,the production of solar pv panels has come to be increasingly efficient, as a result of a rising need for renewable energy sources. Photovoltaic panels are making electricity in over 100 countries globally; irrespective of the simple fact that this energy source is just a very small portion of the world’s electricity production, it has become the most rapidly growing technology of its form .
These technological advancements have as well resulted in pleasing information for the consumer : the size and excellence of production has increased, whilst the cost of photovoltaic panels has reduced. A win-win situation!
Governing bodies in a lot of countries internationally have also announced credits for consumers to install solar pv panels, including rebates and feed-in tariffs. Remote towns and villages no longer have to rely on the typically too high costs of connection to a grid when they make use of solar energy. This allows telecommunications access to all corners of the planet, both on land and at sea.
Solar pv panels also help in making roads more safe, with the use of emergency and warning lights to inform drivers of road work or unsafe driving conditions. This consequently has the capability to save lives, using a cost effective means.
In developing countries, solar energy is a less expensive means by which most of the population can have access to electricity and as a consequence lead an improved quality of life. It allows for the electrification of schools and community centres. When people have access to power, it can extend the time by which productive work can occur, allowing for night time craft work to supplement other forms of income. In disaster circumstances, emergency medical relief teams have the ability to set up well equipped triage centres.
Photovoltaic panels have also been created for recreational use: to power campsites for the adventurer or to deliver a reliable source of power for a computer when travelling.
As we witness non-renewable resources such as coal and gas diminish, it makes sense to take advantage of the sun’s rays.
