Technology and R&D

Indian manufacturer VSole has introduced single-phase hybrid inverters 3 kW to 6 kW with power output ratings. The inverters reportedly allow uninterrupted power to the connected loads, with a UPS-level switching time of four milliseconds.

The new cell category includes perovskite/silicon, perovskite/CIGS, III-V/silicon and perovskite/organic tandem PV devices. It will list the absolute record efficiency for all-perovskite, two-terminal tandems regardless of the number of junctions.

University of Michigan researchers have found that the value of rooftop solar will increase by between 5% and 15% by the mid-century across a range of US cities under moderate climate change, and by up to 20% by the end of the century.

An international team of researchers has proposed a series of processes to recover silicon and other metals from recycled solar cells. Their goal is to reuse the recovered silicon in the PV supply chain.

Australian researchers have developed multi-stage algorithms to remotely detect and accurately diagnose underperforming solar panels in residential and commercial PV systems.

British Gas has developed the Carbon Cruncher tool for the UK market. It contextualizes emissions by comparing them to other emitters.

Scientist in Canada have proposed to combine rooftop PV power generation with an alkaline electrolyzer and a fuel cell to generate hydrogen in buildings. The new system is intended at enabling seasonal energy storage and reduce a home’s levelized cost of energy.

The U.S.-based PV system provider for infrastructure and industrial equipment without grid access has launched a battery health monitoring software module for its flagship Core Solar Power Systems product line.

German certification body TÜV Rheinland has announced the certification of the first organic photovoltaic (OPV) product – an organic PV foil from Germany’s Heliatek – based on the IEC 61215 standard.

Researchers in Sweden have investigated incentive programs for rooftop PV and proposed the adaptation of future schemes to different investor profiles.
