Solar panels were invented to harness energy from the sun (photons) and convert it to usable power for domestic and commercial purposes. The photovoltaic effect converts solar radiation into DC power using semiconductors and most solar panel arrangements contain several solar panels referred to as a photovoltaic array. A photovoltaic array combines the power of several solar panels to achieve the desired power output. Solar panels are sustainable energy options and are particularly useful in countries with lots of sunlight but can extract solar energy easily from less sunny environments so long as there is light. Cheap solar panels are available from general electronic retailers in London and from commercial solar panel suppliers.
Solar Panel Prices
Solar panels come in many different sizes and power output options for various different types of installations and uses. Cheap solar panels are available from London suppliers for around £30 for a 5 watt power output solar panel. Solar panels producing 120 watt outputs on 12v are available for under £400 and a 60 watt for around £220. The options are many and solar panel cost will depend on the intended use and power requirements.
Solar Roof Panels
Cheap solar roof panels in the UK and London are easily available and are included in many house designs where alternative power sources are encouraged for environmental benefits. Solar roof panels are perfectly positioned to extract the maximum amount of solar energy from the sun and convert it into power.
Build Your Own Solar Panel
It is possible to build your own solar panel for use at home, especially for minor tasks such as heating water. There are many informative websites that have detailed instructions on how to build a solar panel and the materials that will need to be purchased. Of course, one will need to buy solar panels, diodes, a battery pack and wiring. All of the other materials that will need to be bought to successfully build a good home solar panel system, are readily available from all good solar panel system suppliers.
Buy a Solar Panel System
Perhaps, for well designed systems that require reliability, it may be best to buy solar panel systems that have been manufactured with a particular purpose in mind. Solar water heating systems are already designed to be placed as solar roof panels and heat the water in very hot countries. The benefits of buying a solar panel system from a reputable London or UK supplier are manufacturer warranty processing if any parts becoming prematurely faulty, professional and experienced installation and application of the solar system which would come with a quality guarantee.
