In its latest monthly column for pv magazine, IEA PVPS shows that with climate-specific site selection, robust design, proper installation, and proactive O&M, most PV systems can be made resilient and remain reliable despite intensifying weather risks.

In its latest monthly column for pv magazine, the International Solar Energy Society (ISES) explains how Australia’s rapid expansion of solar and wind energy has not increased wholesale electricity prices, which have remained stable since 2016. Rooftop solar, now widespread and highly cost-effective, provides the country with resilient, low-emission power, making all-electric homes increasingly independent from the grid.

In a new weekly update for pv magazine, Solcast, a DNV company, reports that Europe’s solar generation potential in November showed a strong east–west split, with Eastern Europe experiencing 15–20% below-normal irradiance due to persistent storms, while much of Western and Central Europe recorded 15–20% above-average levels under clearer conditions. The Atlantic coast was an exception, as Storm Claudia reduced irradiance to near or below average in Portugal, the British Isles, and parts of France and Spain.

This week, Women in Solar+ Europe features Sonia de Sales, Director of Development at Spain’s Altano Energy. She emphasizes that implementing an equal-opportunities plan is key to ensuring open and fair recruitment, including balanced shortlists and actively sourcing female candidates when they are underrepresented, while hiring on merit and making it clearly visible

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.

India’s installed solar capacity reached 132.85 GW at the end of November 2025, led by utility-scale projects in Rajasthan, Gujarat and Maharashtra, according to the central government.

The Australian firm has introduced single-phase 5 kW and 6 kW AC output storage systems, as well as three-phase 10 kW and 12 kW models. Storage capacities of the new products range from 5 kWh to 40 kWh.

A study analyzing urban bifacial PV systems in high-latitude areas found they can generate 9–13% more electricity than monofacial panels under snow conditions, particularly in winter, while also achieving a lower levelized cost of electricity. The research developed a techno-economic optimization model considering snow effects, panel orientation, interrow spacing, and operation modes, highlighting sensitivity to market conditions and discount rates.

The Italian manufacturer said its new Fullness heat pump system has a coefficient of performance of 2.8 and a seasonal energy efficiency ratio of 3.79.

China’s largest polysilicon producers have launched initial steps toward consolidation to curb overcapacity, but OPIS analyst Summer Zhang tells pv magazine that unresolved funding, capacity cuts and governance issues mean prices are likely to see only modest support in the near term without sustained capital injections and stronger downstream demand.

The German specialty glass and materials manufacturer announced a new cerium-doped solar cover glass that is compatible with a range of space solar cell technologies, including III-V and silicon-based concepts. It was developed for use in multiple satellite orbits.

Researchers at Tokyo University of Science showed that sodium-ion batteries with hard carbon anodes can charge faster than lithium-ion batteries by using a diluted electrode method that reveals sodium insertion is intrinsically quicker than lithium.

The research group led by Professor Martin Green has not published yet Version 67 of the solar cell efficiency tables, due to production delays. Green, however, has accepted to comment on some of the results to be added in the upcoming edition.

The result concerns the company’s Comet 3N modules and has been confirmed by TÜV Nord in Germany.

The company deploys first commercial tracking system with a 13-ft. clearance hardened against wind and beef.

Eleven European solar module makers say Italy’s 2026 tax incentive unfairly favors heterojunction (HJT) technology, risks higher costs and limits competition across the PV market.

Accelerated testing by French certification body Certisolis finds wide performance divergence and design vulnerabilities in tunnel oxide passivated contact (TOPCon) solar modules that current international standards do not capture.

An Oxford researcher has found that transparent conducting electrodes can reduce perovskite–silicon tandem solar cell efficiency by over 2%, with losses linked to electrical resistance, optical effects, and geometric trade-offs. Using a unified optical–electrical model, the scientist showed how careful optimization of TCE stacks, coatings, and cell design is critical to closing the gap toward the 37%–38% efficiency frontier.

France-based startup Carbon plans to partner with Chinese manufacturer Longi and adopt back-contact (BC) solar technology as it revises its roadmap for a gigawatt-scale solar module factory.

France-based SPIE has signed a three-year framework agreement with Tesla to deploy Megapack technology across European battery energy storage projects, including a 1.4 GWh facility in the Netherlands.

Canon IT Solutions has begun testing a solar PV system to power its Tier 4 data center in Nishitokyo, aiming to boost renewable energy use and reduce costs. The system is expected to generate around 69 MWh annually and enhance power resilience during emergencies.

Two complaints to the European Commission allege Greek repowering policies and high performance bonds for battery storage projects block upgrades, raise costs, and hinder energy transition, according to industry association Pospief.
