Knight Optical can offer you Stock and Custom Fresnel Lenses, for concentrated photovoltaic applications in a range of materials such as PMMA Acrylic and Borosilicate. CPV is an application which generates electricity from sunlight. The key difference between this technology and conventional photovoltaics (solar panels) is the inclusion of optical components. Utilising optical components which focuses the sunlight onto solar cells increases the efficiency of the electricity generation. Knight Optical provides fresnel lenses which consist of a flat surface with interspace concentric steps whereby each step corresponds to the surface of a conventional lenses. PMMA Acrylic is a preferred material for CPV systems as it is very lightweight when used in a large size. Specialist grades of PMMA are also utilised which absorb the UV light and thus reduces the effects of solarisation i.e. the yellowing of the optical material due to exposure to UV.

This system developed by Reinasan ensures that the efficiency of PVs remains optimal by preventing organic and atmospheric pollution from adhering to the surface. Think, for example, of scale or algae deposits. Rainwater together with the protective coating ensure clean surfaces. The pH neutral and environmentally friendly maintenance agent can be used to support heavy deposits. This saves on the costs of regular cleaning and possible glass corrosion, the energy yield remains high (demonstrably) and heavy chemicals are unnecessary. We are still looking for distributors with their own B2B network. Let's realise a green footprint together!
