A subsidiary of Oil and Natural Gas Corp. is recruiting solar panel suppliers and manufacturers for its future PV projects across India.
Fracsun says it will team up with App Orchid to develop a soiling-loss database and simulation tool.
Scientists in Italy have developed a 5 kW direct-expansion solar-assisted heat pump that uses alternatively two different evaporator technologies. The cooling of the PV module unit by CO2 evaporation increases power production by 8%.
Enfoil is developing a CIGS thin film custom manufacturing business, targeting building-integrated PV applications, such as powering sensors or track & trace sub-systems in trucks. The company is a spinoff of Hasselt University and imec, the Belgian research institute.
Georgia Institute of Technology researchers have used aluminum foil-based negative electrodes with engineered microstructures in an all-solid-state lithium-ion cell configuration. They have reported hundreds of stable cycles with practically relevant areal capacities at high current densities.
Scientists in Cyprus evaluated six different models used to predict the power losses caused by the accumulation of dust, dirt, and other substances on the surface of PV panels in the island’s arid climate. Results from the various models were compared with soiling loss data from a “test bench” installation at the University of Cyprus in Nicosia, revealing a potential advantage for machine-learning approaches backed by satellite data.
China National Offshore Oil Corp. (CNOOC) says it has completed a 40 MW solar-plus-storage plant at an altitude of 3,000 meters. It is connected to 6 MW/12 MWh of battery storage and hosts grazing farm animals.
Romania’s OMV Petrom has acquired a 710 MW solar project portfolio. It said that all of the PV installations are all close to the ready-to-build stage.
New research from Serbia claims air-polluted urban climatic conditions may not only induce maximum power point (MPP) tracking problems in PV systems but also reduce power yield by up to 30%. The scientists also said that soiling may significantly affect the functionality of single-stage inverters operating in grid-forming mode.
Scientists in India carried out a comprehensive study into the impacts of soiling on PV modules – measuring the amount of performance loss caused by different types of dust and bird droppings, and for modules installed at various tilt angles, in the hot-dry climate of Vellore in southern India. Their findings could allow developers to better take into account and mitigate the effects of soiling during site selection and system design.
