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.

pv magazine is compiling a guide to home solar installations, aimed at those who are interested in installing but are new to the market and want to make an informed decision. We have spoken to associations, installers and industry specialists in major solar markets across the globe to compile best practice guidance and advice that aims to be applicable to home solar installations anywhere in the world.

Researchers from Trina Solar and China’s Nanchang University claim to have verified that back-contact solar modules outperform TOPCon modules only when fewer than three cells in a substring are shaded. Their findings were published in a peer-reviewed scientific paper.

InfoLink Consulting says global module shipments rose 10% to 247.9 GW in the first half of 2025, with JinkoSolar narrowly pushing past Longi and tunnel oxide passivated contact (TOPCon) tech accounting for more than 94% of the total.

Chinese researchers, led by a research team from PV Technology Center of Tongwei Co., Ltd, used a sequential annealing process in the fabrication of tandem solar cells, featuring a wide bandgap perovskite top cell on a fully-textured commercial crystalline silicon heterojunction bottom cell. The resulting device had a certified power conversion efficiency of 31.4%, outperforming a 29.43%-efficient control cell.

Chinese manufacturer Anker Solix has introduced the Solarbank Multisystem, along with a Power Dock control unit enabling parallel operation of up to four battery storage units.

The Solar Energy Corp. of India (SECI) has successfully concluded its seventh green ammonia auction under Mode-2A of the SIGHT Scheme, allocating a capacity of 50,000 metric tonnes per annum (tpa) at a discovered price of INR 51.89/kg.

The first part of the series aims to help homeowners looking to embrace PV identify the best installers on the market.

UNSW researchers have investigated the impact of two types of soldering fluxes on TOPCon solar modules under damp heat conditions and have found that “no-clean” soldering fluxes can cause severe corrosion of front silver-aluminum contacts. The researchers have also found that denser metallisation structures and lower aluminium content improve corrosion resistance.
