Sun-X secures patent for PV sensor that measures soiling, yield loss – pv journal Worldwide

From pv journal Germany

Germany-based Sun-X has obtained a patent from the European Patent Office for a sensor that may detect air pollution ranges in PV modules.

The Sunsoric sensor makes use of a light-weight supply that shines on the floor of the PV module. Particles of mud and grime on the glass mirror gentle in another way in comparison with a clear pane, and a receiver diode captures this distinction for calculation.

According to Sun-X, the sensor algorithm can detect crop loss attributable to contamination with 1% accuracy. The system adjusts for the contamination of the sunshine supply and receiver, and this reliability is verified by an unspecified Fraunhofer Institute.

This info is processed by means of a cloud, which incorporates system design and climate knowledge to find out the perfect cleansing time. Sun-X additionally provides the “sunbotics” cleansing robotic for this function.

“We have been working with Sunsoric for greater than three years – all the time with the aim of figuring out correct contamination knowledge,” mentioned Pascal Liebold, founder and managing director of Sun-X. “This is a very powerful consider calculating the perfect cleansing time. The patent is an enormous milestone and can assist us proceed to develop and construct our know-how lead.”
