Adani Green, Acme Solar add 300 MW to India PV project pipeline
Adani Green and Acme Solar have ramped up their utility-scale solar footprints in India with new project activations in Gujarat and Rajasthan, respectively.
New method to verify warranty conditions of PV modules
Scientists have developed a way to compare the data given by PV manufacturers based on standard test conditions (STC) to the real conditions in the field. The proposed technique is based on the single-diode model and the Newton-Raphson algorithm. The maximum relative error was found to be at 1.37%.
Cooling bifacial PV modules with mist
Scientists have placed mist nozzles inside a bifacial PV module and measured it under an extremely hot climate. The module was found to generate up to 37% more electricity on sunny days and up to 46% more on cloudy days compared to standard monofacial panels.
SolarEast debuts new residential propane heat pumps
The Chinese manufacturer said its new heat pump systems have a heating capacity of 4 kW to 16 kW and a coefficient of performance of up to 5.05.
World’s first offshore wind-solar project moves forward
An offshore solar farm is being deployed close to an existing wind farm as part of a project in the Dutch North Sea. The developers have recently installed an anchoring system that will hold the solar farm in place while an electrical cable connects the array to a nearby wind turbine foundation.
