History of Kipp & Zonen

Quality and innovation have been hallmarks of Kipp & Zonen since 1830, when founder Dutch pharmacist Petrus Jacobus Kipp, opened his instrument business.

In 1844, he developed an apparatus called the Kipp generator, designed for the preparation of small volumes of gases, and became widely used around the world.

After Kipp’s death in 1864, his wife and one of their sons carried on the business under ‘Kipp & Zoon’ (son). In 1866 two sons, Anthonius Johannes (instrument-maker) and Wilhelmus Arnoldus (pharmacist), continue the firm under the name Kipp & Zonen (sons).

In 1923 Prof. Dr. Willem Jan Henri promotes the thermopile at a meteorological congress in Utrecht. Dr. Ladislas Gorczynski (Meteo Warsaw) is interested and constructs a thermo-electric pyrheliometer and makes the first daily curves of direct solar radiation with his recording galvanometer. Both scientists worked together to create the first pyranometer in 1927.

In 2017, Kipp & Zonen became a part of Hach, a subsidiary of Veralto Corporation, and is now one of the strong global product brands that make up OTT HydroMet.

Kipp & Zonen has become the worldwide specialist in solar and sky radiation, providing class-leading instruments for measuring solar radiation and atmospheric properties in
meteorology, climatology, hydrology, industry, renewable energy, agriculture and public health and help customers monitor atmospheric properties related to climate change, classical meteorology, available water budget and more.

The array of high-quality solar and atmospheric science instruments feature all-weather radiometers, data loggers, and complete measurement systems. All instruments are fully traceable to applicable World Meteorological Organization (WMO) and ISO standards.

Building an Effective Meteorological Station for Solar PV

Weather conditions have a huge influence on photovoltaic output. Even intermittent cloud cover can have a dramatic effect on incident solar energy, while other factors like air  temperature, wind direction and speed, precipitation, humidity and air pressure can all influence the efficiency of solar cells. Monitoring weather conditions accurately is crucial to understand variations in PV plant performance.
