Just about everyone has seen or used a calculator that uses solar energy and we understand just how useful they are. You don’t need to use replacement batteries and they appear to operate for a lifetime, provided there is plenty of light.

Maybe you have also seen the always expanding use of solar panels in much larger gadgets, like emergency road signs, telephone boxes and lighting for car parking stations. More and more of these useful units are being powered by the sun instead of relying upon the more traditional forms of electricity.

So, you ask: How do these things work?

The answer is photovoltaics. This particular technology has been in operation ever since the late 1950s and was used principally in space, powering the electric systems in satellites. Currently, the technology is used in more run of the mill applications. Some individuals are convinced that the potential of the sun will ultimately be utilized to drive effective motor vehicles and that all of our power needs will be without charge.

Solar pv panels, also known as photovoltaic panels, create electrical energy through the conversion of solar radiation into direct current (dc) electricity employing semiconductors. This direct current is what we obtain through mains or grid power. An inverter is vital to convert dc power to ac, which is the type of electricity utilised for such purposes as boats, electric cars and roadside emergency telephones.

Each of these solar pv panels incorporate a number of cells and these cells in turn contain photovoltaic material. The most generally employed materials are made up of silicon. This material by its very nature must be protected from the ravages of weather: normally this means it is crammed snugly behind a sheet of glass. For situations in which a more significant level of power is needed, the panels are joined in arrays.

In just ten years,the production of solar pv panels has grown to be increasingly efficient, in response to a rising demand for renewable energy sources. Photovoltaic panels are making electrical power in over 100 countries world wide; despite the simple fact that this electricity source is just a tiny portion of the world’s electricity production, it is the fastest growing technology of its form .

These technological developments have as well resulted in pleasing facts pertaining to the consumer : the scale and quality of manufacturing has elevated, whilst the pricing of photovoltaic panels has decreased. A win-win situation!

Governing bodies in a lot of countries globally have also announced incentives for consumers to install solar pv panels, including rebates and feed-in tariffs. Remote towns and villages don’t have to rely on the frequently prohibitive costs of connection to a grid when they utilise solar energy. This allows telecommunications access to all corners of the planet, both on land and at sea.

Solar pv panels also assist in ensuring that roads are less hazardous, with the use of emergency and warning lights to advise road users of road work or hazardous driving conditions. This consequently may have the potential to save lives, using a cost effective means.

In developing regions of the world, solar energy is a less expensive means by which the greater proportion of the population can have access to electricity and as a result lead a better quality of life. It enables electrification of schools and community centres. When individuals have access to reliable energy, it can lengthen the time by which productive work can happen, allowing for night time craft work to supplement other forms of income. In natural disaster circumstances, emergency medical relief groups have the ability to set up well equipped triage centres.

Photovoltaic panels have also been designed for recreational use: to power campsites for the more adventurous or to produce a reliable source of power for a computer when travelling.

As the non-renewable resources such as coal and gas diminish, it makes sense to take advantage of the sun’s rays.
