Just about everyone has seen or made use of a calculator which uses solar energy and we realise exactly how convenient they can be.

There isn't a need for replacement batteries and they seem to operate for a long time, provided that there is adequate light. Maybe you have also seen the always increasing use of solar panels in larger devices, such as emergency road signs, telephone boxes and illumination for car parking bays. More and more of these handy devices are being powered by the sun instead of relying upon the more standard forms of electricity.

The question is: how do they work?

The answer is photovoltaics. This technology has been utilised since the latter part of the 1950s and was used largely in space, powering the electrical systems in satellites. Currently, the technology is utilised in more run of the mill applications. Some individuals believe that the potential of the sun will at some point be controlled to drive reliable motor vehicles and that all of our power requirements will be cost free. PV panels , also known as solar photovoltaic panels, produce electrical power by means of the conversion of solar radiation into direct current (dc) electricity using semiconductors. This direct current is what we access from mains or grid power. An inverter is vital to convert dc power to ac, which is the form of electricity utilised for such functions as boats, electric cars and roadside emergency telephones. Each of these solar pv panels incorporate a quantity of cells and these cells consequently contain photovoltaic material.

The most typically used materials are made up of silicon. This material has to be protected from the ravages of weather: typically this means it is crammed snugly behind a sheet of glass. For scenarios where an increased quantity of energy is required, the panels are linked in arrays. Within the last ten years, the production of solar pv panels has grown to be more efficient , as a consequence of a growing requirement for renewable energy sources. Photovoltaic panels are generating electricity in more than 100 countries world wide; despite the simple fact that this electricity source is but a tiny fraction of the earth's electricity production, it is the most rapidly expanding technology of its sort.

These technological improvements have additionally resulted in pleasing information pertaining to the customer : the scale and quality of manufacturing has increased, whilst the expense of photovoltaic panels has lessened. A win-win situation! Governments in several countries internationally have additionally announced credits for purchasers to install solar pv panels, including rebates and feed-in tariffs. Rural towns and villages don't have to count on the frequently exhorbitant costs of connection to a grid when they make use of solar energy. This allows for telecommunications access to all corners of the world, both on land and at sea. Solar pv panels also help in ensuring that roads are less dangerous, with the use of emergency and warning lights to advise road users of road work or hazardous driving conditions. This consequently has the possibility to save lives, using a cost effective means.

In developing nations, solar energy is a less expensive means by which the greater proportion of the population is able to have access to electricity and as a consequence lead a better quality of life.

It allows for the electrification of schools and community centres. When individuals can access power, it can extend the time by which productive work can happen, enabling night time craft work to supplement other forms of income.

In disaster situations, emergency medical relief teams can set up well equipped triage centres. Photovoltaic panels have also been produced for use in recreational activities: to power campsites for the adventurer or to generate a reliable source of power for a computer when on the road. As we witness non-renewable resources such as coal and gas dwindle, it makes sense to take advantage of the sun's rays.
