A team of international scientists has installed a high-altitude weather station near the summit of Aconcagua, the tallest mountain in the Western and Southern Hemispheres. This station is the final addition to a network of five observation sites, providing crucial data on water availability in the Central Andes, a region facing a 15-year mega-drought. Despite its importance as a key water source for Argentina, the area has historically been under-monitored. This initiative aims to improve climate resilience and resource management.

IEC61724 recommends Class A sensors be re-calibrated once every 2 years, or more frequently per manufacturer recommendations and for Class B sensors, according to manufacturer recommendations.
To ensure an accurate and reliable measurement, and to stay compliant with IEC and WMO recommendations, we at OTT HydroMet suggest getting pyranometers re-calibrated every two years.
To this end we are offering the month of calibration for pyranometers, where you will not only get 15% discount per calibration but also a quick turn-around time.

Voilà, here is the third issue of OTT HydroMet Insights! This time, we take a detailed look at the solar energy landscape, international standards, new applications and technologies.
April 25, 2022
Solar energy is central to reaching climate targets across Europe. Now it is beginning to make its comeback in Germany and is once again gaining momentum with the plans laid out by the German government to reach an installed PV capacity of 200 gigawatts (GW) by 2030. Germany continues on its path to becoming the leading PV market in Europe. A good time to join the international solar industry, that will meet on May 11–13, 2022, at Intersolar Europe in Munich at Messe München.

We are very happy to share with you our second issue of the OTT HydroMet Insights for all Experts in Meteorology.
Feb 2019
We have a lot of contacts with existing and prospective customers in the solar energy industry; at exhibitions, in workshops or by email and through the Kipp & Zonen support system. Many of the same issues keep coming up, in one form or another. So, we have decided to put together a whitepaper that addresses the most common requests for information and explanation. This is particularly topical because there is a lot of confusion resulting from recent changes in key international standards.
Nov 2018
Historically, Kipp & Zonen pyranometers with a higher model number have better specifications and a lower measurement uncertainty. As a result, there has been some confusion in the market and the impression that the CMP10 and Smart SMP10 models are in some way inferior to their CMP11 and SMP11 cousins.
In fact this is not true. If you look at the brochure for our pyranometer range you will find that CMP10 and CMP11 share the same column in the CMP model range specification table, as do the SMP10 and SMP11 models in the SMP range table.

Last week my product management dashboard started blinking. But why? It turned out to be the alarm I’ve set almost a year ago for reaching 500 delivered and invoiced RT1 sensors. Time for a small celebration as the normal product adaptation period in our market is 3 to 4 years and the RT1 isn’t even a year old. Evidently the RT1 is the right product at the right time.

Measuring solar irradiance in a highly accurate way is achieved by using a pyranometer complying with ISO 9060. Although most meteorological data is based on horizontally mounted pyranometers, with Photovoltaic (PV) panels it is also important to know the tilted global solar irradiance. This article explains more about measuring solar irradiance and the difference in horizontal and tilted pyranometers.

How does a pyranometer work? As the experts in solar radiation measurement we are often asked this question and we are happy to answer with an explanation of the working principle of thermopile pyranometers. We have been manufacturing them since 1924 and have evolved the principle to the best instruments available today.
One of the first customers to use DustIQ was Green Energy Park in Morocco, to support research field tests. Since February 2018, OTT HydroMet's DustIQ Soiling Monitoring System has been on their site and measuring the on-site soiling ratio.
Easily Check Kipp & Zonen Instruments on Site. METEON 2.0 can be connected to any of our pyranometers and provide you with real-time measurement values.
Many people have asked us for an illustration that gives a simple overview of the three components of incoming short-wave solar radiation: direct, diffuse and global.
