Solar PV

Market pressure in the solar and storage sectors often favors low-cost solutions, but long-term success depends on balancing price, quality, and reliability for assets designed to operate for decades. Numerous examples, from low-grade silicon modules to residential hydrogen and redox flow storage, show how technically ambitious products can fail when costs, complexity, or durability are misjudged.

Mexico’s energy ministry has approved 20 new renewable energy projects, 15 of which are solar, following an October decree regulating private sector investments in the country’s energy sector.

China’s commerce ministry has raised a complaint at the World Trade Organization (WTO) regarding India’s solar subsidies, claiming they give the country’s domestic industry an unfair advantage and harm Chinese interests.

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.

Italian energy group Eni and solar manufacturer FuturaSun have launched SunXT, a new startup focused on developing and producing perovskite-silicon tandem solar modules, building on FuturaSun’s research expertise.

A team at Fraunhofer ISE has created new imaging methods to measure losses in individual sub-cells of multi-junction solar cells based on perovskite-silicon and perovskite-perovskite-silicon combinations.

Researchers in Slovakia have demonstrated a machine-learning framework that predicts PV inverter output and detects anomalies using only electrical and temporal data, achieving 100% accuracy in classifying inverter output states under static operating conditions at a solar installation.

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, 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.

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.
