Photovoltaic Panels - Solar PV Panels

Just about everyone has seen or used a calculator that uses solar energy and we realise just how convenient they are. There isn’t a need for replacement batteries and they seem to work indefinitely, so long as there is sufficient light.

Maybe you have also seen the an development in the use of solar panels in much larger products, such as emergency road signs, telephone boxes and illumination for car parking bays. An increasing number of these useful gadgets are now powered by the sun instead of using the more standard forms of electricity.

So, you ask: How do these things work?

The answer is photovoltaics. This technology has been in operation since the late 1950s and was used most often in space, running the electric systems in satellites. Currently, the technology is used in more every day applications. Some individuals believe that the power of the sun will eventually be controlled to run effective motor vehicles and that just about all of our power requirements will be without charge.

Photovoltaic panels, also known as pv panels, produce electricity by way of the conversion of solar radiation into direct current (dc) electricity employing semiconductors. This direct current is what we gain access to from mains or grid power. An inverter is required to change dc power to ac, which is the kind of electricity used for such functions as boats, electric cars and roadside emergency telephones.

Each of these solar pv panels consist of a quantity of cells and these cells in turn contain photovoltaic material. The most generally used materials are made of silicon. This material has to be protected from the elements: generally this means it is crammed snugly behind a sheet of glass. For situations in which a more significant volume of electricity is needed, the panels are linked in arrays.

During the last ten years, the production of solar pv panels has become more efficient , in response to a rising need for renewable energy sources. Photovoltaic panels are creating electricity in over 100 countries world wide; despite the reality that this power supply is but a very small fraction of the earth’s electricity production, it is the most rapidly growing technology of its form.

These technological advances have also resulted in pleasing information pertaining to the consumer : the level and quality of manufacturing has grown, whilst the expense of photovoltaic panels has reduced. A win-win situation!

Authorities in several countries globally have also announced bonuses for consumers to install solar pv panels, including rebates and feed-in tariffs. Remote towns and villages don’t have to rely on the typically prohibitive costs of connection to a grid when they make use of solar energy. This allows telecommunications access to all corners of the globe, both on land and at sea.

PV panels also assist in making roads more safe, with the use of emergency and warning lights to advise road users of road work or hazardous driving conditions. This in turn has the capability to save lives, using a cost effective means.

In developing nations, solar energy is a cost effective means by which the greater proportion of the population is able to have access to electricity and as a result lead a better quality of life. It allows for the electrification of schools and community centres. When individuals can access power, it can increase 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 are able to establish well equipped triage centres.

Photovoltaic panels have also been produced for recreational use: to power campsites for the adventurer or to deliver a reliable source of electricity for a computer when on the road.

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