There are lots of types of solar panels available in the UK, and the main differences are in the materials and how they’re made. The most common type is monocrystalline panels, which are made from single-crystal silicon and tend to be the most efficient and compact. Polycrystalline panels are another common option; they are generally slightly less efficient but often cost less. Thin-film panels are less common for homes but can be useful in certain situations because they are lighter and can be more flexible, though they usually need more space for the same output.
There are also panels designed for specific purposes, such as high-performance panels for limited roof space or panels with integrated microinverters. Some systems use battery storage alongside panels to make the most of the energy generated. A professional installer can help you choose the right type based on your roof, budget, and energy needs.
