PV panels are interconncted assemblies of photovoltaic cells most commonly bonded to glass and in an aluminium frame. There are three main types of panels available: monocrystalline, polycrystalline and 'thin film'. Monocrystalline cells are cut from a single cylindrical crystal of silicone and the panels are more efficient but are slightly more expensive. Polycrystalline cells are cut from an ingot of melted and recrystallised silicone and the panels are less efficient and are slightly cheaper. Thin film cells are assembled into modules by laminating them to a flexible film. Ideal where there is plenty of roof space, they are even less efficient but cheap to produce and install.
In order to qualify for the Feed In Tariff, the panels must come from the list of accredited products on the Microgeneration Certificate Scheme website. We have installed a lot of Sanyo, Sharp and Upsolar panels but also fit Schuco, Canadian Solar, Schott, Kyocera and Scheuten. Like you, we always look for the best performance combined with long term reliability.
