PV module IV curve is a powerful diagnostic tool for understanding how a photovoltaic module actually performs under real-world conditions. It shows how current and voltage interact and helps verify system health, detect performance losses, and support reliability assessments for engineers, O&M teams, EPCs, and asset owners.This guide explains what a PV module IV curve is, how to interpret it, ...
Soiling—accumulation of dust, dirt, pollen, agricultural residue, and other airborne particulates on PV module surfaces—causes light transmission losses and measurable power reductions. While its impact on ongoing operation is well established, soiling also affects capacity and performance testing, where even small losses can carry contractual and financial implications. Field studies indicate ...
Accurate irradiance data is the backbone of solar project performance, bankability, and long–term investor confidence For EPCs, it shapes everything from yield assessments and energy modeling to commissioning acceptance tests and contractual guarantees. But this reliability depends on a critical assumption: the irradiance measurements used to validate performance are accurate. ...
Solar and hydropower are two pillars of the global renewable energy mix, but their true potential emerges when they work together. Research from the U.S. National Renewable Energy Laboratory suggests that hybrid systems combining these sources could unlock energy outputs in the range of thousands of terawatts. A game changer for sustainable power generation. At the core of this ...
In Austria, a pioneering network of 1,000 modern weather stations is being established to set new standards in local weather forecasting. In cooperation with two weather services, the telecommunications provider Drei Austria, together with Metrilog Data Services GmbH and Meteologix AG led by weather expert Jörg Kachelmann, is bringing this technology across the entire country – with ...
In the world of solar energy measurement, precision and reliability are non-negotiable. For around a century, Kipp & Zonen has set the benchmark in solar irradiance monitoring, and nothing illustrates this legacy better than the long-standing partnership with the University of Applied Sciences in Saarland, Germany. Back in the early 1990s, the institute began using Kipp & Zonen ...
To kick off our ISO 9060:2018 solar irradiance measurement educational series, we are delving into the technical specifications and science behind the response time of your pyranometers. ...
Flood monitoring is a crucial part of civil protection and urban planning. As extreme weather events become more frequent, it is more important than ever that municipalities, engineering offices and emergency services such as fire departments and disaster control are well informed and prepared. In this blog post, we answer frequently asked questions about flood monitoring to give you a ...
The importance of flood monitoring is steadily increasing as heavy rainfall events become more frequent, requiring monitoring even in previously unaffected areas. This development calls for comprehensive and reliable monitoring to respond to flood events in a timely manner and minimize damage. However, the planning of a monitoring station can seem complex and overwhelming. In this blog ...
Water level monitoring is crucial for managing water resources, flood mitigation, and environmental protection. With the launch of the OTT RLS 500, a next-generation radar level sensor, it’s an excellent time to explore the different technologies available for water level measurement and their applications in various sites, such as streams, rivers, and reservoirs. ...
n the lead-up to his upcoming webinar on solar O&M with SolarCleano, a Luxembourg-based company specializing in solar panel-cleaning robotics, we sat down with Udo Kronmueller, our Applications Development Manager for Solar. Udo shared insights into the impact of soiling on PV sites, covering topics from evaluating performance ratios to optimizing operations and maintenance ...
Advanced monitoring and modeling techniques are improving torrent barrier design to better manage flooding in the Alps. Torrent barriers are crucial in managing the flow of water and sediment in mountainous regions, particularly in the Alps, where climate change is increasing the frequency and intensity of torrential rain events. These structures prevent the buildup of sediment that can ...
Within its highest Class A, OTT HydroMet manufactures three different smart pyranometers under their Kipp & Zonen brand. ...
In the face of global warming, understanding the behavior of polar ice sheets has taken on new urgency. The Greenland ice sheet, the second-largest body of ice on the planet after the Antarctic ice sheet, plays a critical role in this context, contributing greatly to rising sea levels. In fact, if the entire Greenland ice sheet were to melt away it could contribute to a global sea level ...
To maximize irradiance yield, the engineers are aligning the 26-ton concentrator with the path of the sun, utilizing data from the RaZON+ sun tracker by OTT HydroMet’s product brand Kipp & Zonen. Often times, the first thing that comes to mind when talking about solar energy is photovoltaics (PV). ...
A complete measurement of solar irradiance includes global (GHI), direct (DNI), and diffuse (DHI or DIF) radiation. To accomplish this, a high-quality solar monitoring station typically comprises an automatic sun tracker fitted with instruments to measure these components individually. Depending on the application, long-wave radiation and reflected short-wave radiation may be added to provide the ...
The University of Freiburg is one of the top universities in Germany and has been recognized for excellence in research and education for the last 565 years. In fact, 23 Nobel Prize laureates have researched, taught, and studied at the university. Markus Weiler is a Professor of Hydrology & Chair of Hydrology in the Faculty of Environment and Natural Resources and explains why ...
Professionals around the world trust in OTT HydroMet’s ceilometer series Lufft CHM. Thanks to its robust, stand-alone design and reliable measurement performance the Lufft CHM 8k and CHM 15k have become the instrument of choice of meteorologists at weather services, research institutes, and airports. ...
Monitoring the conductivity of groundwater and surface water is an essential task for maintaining the quality and safety of our water resources. Continuous monitoring of conductivity can help identify long-term trends and seasonal variations in water quality, which are used to predict changes in water availability and quality over time. This can aid in the development of effective ...
On a recent site visit, Danail Kuzarow, Sales Director at OTT HydroMet, joined Reiner Haseloff, Prime Minister of Saxony-Anhalt, and Heike Brehmer, member of the German Federal Parliament to celebrate the inauguration of a new monitoring network in Germany. ...
