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.

Repair and service for SolarEdge inverters The SolarEdge single-phase inverter with HD-Wave technology represents a quantum leap in PV inverter technology. Since the MPPT and voltage control for each PV module is carried out separately by the SolarEdge power optimizer, the single-phase inverter only converts direct current into alternating current. With the repair of SolarEdge inverters, problems and error messages with SolarEdge inverters are not only identified by us, but also resolved in the form of a complete product overhaul of your SolarEdge photovoltaic inverter. The technical expertise and service competence of our company is based on decades of repair experience in the field of maintenance of industrial electronics, in which BVS Industrie-Elektronik GmbH is one of the industry leaders.

Repair and service for Sungrow inverters In our product range you will find both string inverters and central inverters from Sungrow. With the repair of Sungrow solar inverters, problems and error messages with Sungrow inverters are not only identified by us, but also resolved in the form of a complete product overhaul of your Sungrow photovoltaic inverter. The technical expertise and service competence of our company is based on decades of repair experience in the field of maintenance of industrial electronics, in which BVS Industrie-Elektronik GmbH is one of the industry leaders.
