Polycrystalline solar cells
It is rather cheaper to produce silicon wafers in polycrystalline form, as the conditions can be less tightly controlled. In this form a number of interlocking silicon crystals grow together. Panels based on these cells are cheaper per unit area than monocrystalline panels - but they are also less efficient, and in terms of pounds-per-watt there is not a great deal of difference.
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.
