Types of solar panel
There are three main types of solar panel in commercial production, all with some advantages and disadvantages. All three are based on silicon semiconductors - the difference is the form that the silicon is in. Panels based on other chemistries are under development. Cadmium telluride and copper indium diselenide panels may well appear in production soon, and there is also research being carried out on using the photosynthesis effect that plants use to convert sunlight to useful forms of energy. However, you are unlikely to come across technologies other than silicon for the time being, so we will just consider silicon on this page..
Robust amorphous silicon solar panels. Vandal resistant and great value.
Polycrystalline frameless solar panels that can take a gentle curve. Available in 5, 10 or
20W
Flexible thin-film solar panels with an adhesive backing.
Polycrystalline solar panels with exceptionally robust frames and superb build quality.
Small wind turbines, ideal for battery charging on yachts.
Reliable vertical axis turbines - great for remote power solutions.
Efficient fluorescent lighting for boats and caravans.
