In arid regions soiling can greatly impact the energy yield of PV systems and drive up their O&M costs. Benjamin Figgis, Amir Abdallah, Maulid Kivambe, Brahim Aissa, Kamran Ali, Cédric Broussillou and Veronica Bermudez of the Qatar Environment & Energy Research Institute and Klemens Ilse of the Fraunhofer Center for Silicon Photovoltaics review the main challenges associated with soiling of PV plants globally, and the most promising techniques for dust prevention and cleaning in dry climates, drawing on research results from six years of PV performance and soiling studies at the QEERI’s Outdoor Test Facility in Doha
How PV module supply has now become a marketing and trade-show related game of numbers; what is driving this, and why is it perhaps causing more concern to the very grouping it is meant to impress – the end-user.
By adopting and modifying technology initially developed by NASA, SunSniffer is able to provide STC (Standard Test Conditions) values of each individual module, on a constant basis during pv power plant operation. This unique technology has been developed with the German Aerospace Center, which consists of software managing Big Data with artificial intelligence and high-precision measuring hardware.
US-headquartered high-efficiency PV module producer SunPower Corp has secured the module supply deal for innogy’s 349MW PV power plant near Balranald, New South Wales, Australia, the largest plant under construction in the country.
Distribution company Gujarat Urja Vikas Nigam Limited (GUVNL) has invited expressions of interest (EoI) for development of 1GW of PV capacity in a solar park at Dholera Special Investment Region (DSIR), Gujarat.
