Smart performance


It was a great pleasure for us at PES to speak with Kees Hoogendijk, Managing Director, EKO Europe. Accuracy is of paramount importance to this company and now they have made improvements to their already world famous pyranometer and launched the new MS-80S, with multiple added aspects of value for their customers. To produce the smartest, most innovative, accurate, and best in class sensors on the market remains their quest, so we’re sure we can expect more in the future.

PES: Hi Kees, welcome back to PES Solar. We have worked with EKO for many years and it’s good to have the chance to speak with you. For the benefit of our new readers could you give us a brief overview of EKO? What products are you best known for?

Kees Hoogendijk: EKO Instruments was founded in Japan over 90 years ago, and develops industry-leading solar energy sensors, and scientific instruments for environmental research.

One of our most famous products is the MS-80 pyranometer. We launched it in 2016 and until recently it was the only ISO 9060:2018 Class A solar sensor on the market in the top tier ‘fast-response’ and ‘spectrally flat’ sub-categories. We’ve since launched the MS-80S so there are now two best in class pyranometers, both made by EKO.

PES: We know that EKO’s monitoring systems and pyranometers are renowned for their accuracy, how did this come about?
