DustIQ now has on-site calibration If you search the internet for ‘soiling of PV modules’ you DustIQ has unique features. No outside light source is needed, ﬁnd more than half a million webpages and over 6,000 so it works day and night. The two sensors are not for a scientiﬁc papers on the subject! Countless hours have clean-dirty comparison, but to have two independent spot been spent researching this challenge for solar energy measurements to compare and use. DustIQ does not need to technologies. The locations on our planet that seem have a clean surface, it gets dirty at the same rate as...

Local dust calibration A major recent enhancement is the addition of a small PV cell that is used for local dust calibration (LDC). The standard factory calibration is for Arizona Test Dust but, using a simple procedure, DustIQ can be site-calibrated for the local dust composition and the effect of it on the sunlight transmission loss. A clean DustIQ is installed and left to get dirty until it reports at least 10% transmission loss. The 15 minute calibration procedure can then be carried out. It needs to be performed only once and no tools or software are needed, just pressing a button. The...

NOORinII and III Giant power plants Morocco equipped with Kipp & Zonen solar monitoring By Eduardo de Ugarte Martínez, Business Development Manager at DILUS Instrumentation y Sistemas of Madrid DILUS has for many years been the Kipp & Zonen distributor for Spain, working with all the major renewable energy utilities and solar engineering and technology companies. DILUS has supplied and installed over 200 Kipp & Zonen trackers and one of our latest projects is to provide the meteorological and radiometric instrumentation systems for the innovative Noor solar energy complex in Morocco....

Noor I, was officially commissioned in February 2016 and involved the construction of a 160 MW concentrated solar power (CSP) plant. It has half a million ‘rocking’ parabolic trough reflectors covering 450 hectares. The focused sunlight heats up a transfer fluid which is then used as the energy source for conventional steam turbine electricity generators, instead of oil or gas. Excess energy is used to heat molten salt, which is stored in heavily insulated tanks at about 560°C and can be used to produce steam. When fully charged the Noor I storage system can provide up to 3 hours of...

Lufft weather sensors with Kipp & Zonen on top When Kipp & Zonen joined the OTT Group in January this year it became a sister company to G. Lufft Mess- und Regeltechnik GmbH of Fellbach, Germany. Actually, we have had a relationship for many years. At sites where solar radiation is measured it is often required to monitor other environmental and meteorological parameters that affect the weather, climate, agriculture, water resources, and the output of solar energy plants. There are countless situations where you can see one or more Kipp & Zonen pyranometers installed with a Lufft all-in-one...

These models are typically installed along with several Kipp & Zonen SMP series Secondary Standard pyranometers to measure global horizontal, and plane of array, irradiance (GHI and POA). All the outputs are connected into a local digital data logger or networked to a plant Supervisory Control and Data Acquisition (SCADA) system. With the addition of PV module back-of-panel temperature sensors and DustIQ all the information necessary for high quality solar energy production monitoring is provided. The ideal set up for calculating performance ratios and for operation and maintenance...

Irradiance monitoring systems for rooftop photovoltaic installations By Jake Wilkinson, Editor at AZoNetwork Rooftop Solar Installations are the Future Rooftop solar is on the rise. While widespread adoption of feed-in tariffs in the early 2000’s fuelled early uptake of solar technology by lessening the ﬁnancial burden to investors, advancements in photovoltaics are yielding increasingly efﬁcient solar cells at ever lower costs. Rate of uptake of solar is increasing faster than for any other energy source: in 2016, new global solar PV capacity increased by over 50% and exceeded 74 GW.The...

CREST investigates the beneﬁts of AirShield® DNI in a less obvious climate 12 By Brian Goss, Ian Cole and Patrick Isherwood, Centre for Renewable Energy Systems Technology (CREST), Loughborough University, UK We, the Centre for Renewable Energy Systems Technology (CREST) of Loughborough University, were one of the ﬁrst to install the AirShield® DNI for pyrheliometers since Kipp & Zonen redesigned it and started manufacture. The Applied Photovoltaics group at CREST specializes in improving the performance and reliability of PV systems. Having reliable and long term solar irradiance data is...
