Scientists in Ireland investigated the effect of shunt resistance on a PV cell’s electrical performance. The group says its finding could potentially lead to the development of models for early detection of various forms of cell degradation, allowing for intervention to repair or replace components before major power losses occur.

After four years of development, French-Italian carmaker Stellantis, French battery company Saft, and the French National Center for Scientific Research (CNRS) have unveiled the Intelligent Battery Integrated System (IBIS), which integrates the electric charger and inverter functions. It can be used in automotive and stationary storage applications.

Researchers in Spain have studied the impact of hydrogen production and storage technologies in risk management for energy communities with internal price-tariff systems. They found that the optimal involvement in futures markets and spot markets will depend on a community’s risk aversion and self-sufficiency.

US researchers have developed new integrated halide perovskite photoelectrochemical cells, while Fortescue Future Industries has revealed plans to acquire a hydrogen project from Nikola in Arizona.

In a new weekly update for pv magazine, OPIS, a Dow Jones company, provides a quick look at the main price trends in the global PV industry.

China-based GoodWe has developed two new solutions – the ETC 100 kW hybrid inverter and the BTC 100 kW retrofit battery inverter – for commercial and industrial (C&I) solar applications.

Utilities increasingly recognize heat pumps as a critical technology for heat decarbonization. They are deploying multi-megawatt systems in different parts of Europe to simultaneously serve multiple users and offer new avenues for the decarbonization of buildings.

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.

In this exclusive interview with pv magazine, Guoguang Chen, President of Smart PV & ESS Business at Huawei Digital Power, in this, discusses company strategy and recent announcements around FusionSolar, latest technology and product innovations in solar and storage, and more.

Mercom Capital Group’s latest report shows that almost 25.5 GW of solar projects were acquired in the first half of this year, totaling $18.5 billion.
