How does a solar panel work?
Solar panels create electricity using a photovoltaic (PV) process which converts sunlight into electricity. A Photovoltaic cell consists of two or more thin layers of semiconducting material, most commonly silicon. When the cell is exposed to light, electrical charges are generated and this can be conducted away by metal contacts as direct current (DC). The electrical output from a single cell is small, therefore multiple cells are connected together to provide a more useful output. Cells connected in this way are encapsulated (usually behind glass) to form a weatherproof module or panel. Individual panels are then interconnected to form strings.
Geo Green Power will be on hand to advise on any planning requirements for small, large or bespoke installations. If permission does needs to be sought, we can provide full assistance in completing applications and supplying any information requested by the local planning authority to ensure the process is as quick and easy as possible.
How long has Solar PV technology been around?
In 1838 the photoelectric effect was discovered by physicist Edmund Becquerel although it wasnโt until the 1950โs that the technology was developed enough to produce efficient working cells. During the 50โs and 60โs Solar PV was put on satellites and sent into orbit but it was still too expensive for general use. The next few decades brought better technology with lower prices and Solar PV was installed in some remote locations to provide electricity where there was no supply. Grid-connected Solar PV has had a massive growth since 1990โs in the more developed countries of the world.
Are Photovoltaic panels expensive?
Over the last decade, installation cost have fallen significantly, on average a solar PV installation will cost around ยฃ1,000 per k/W of in install capacity. But it has the advantage of using highly reliable (largely maintenance free) components.
