Canadian startup unveils AI tool for solar panel cleaning optimization
Swish Solar has an AI-driven tool that optimizes solar panel cleaning schedules to reduce soiling losses and operating costs. The platform uses data analytics and forecasting models to help operators time cleaning based on financial impact.
Iran conflict stirs solar demand debate in Germany
Germany’s solar sector is reporting a surge in inquiries following the military escalation between Israel, the United States, and Iran, with E.ON citing a doubling of demand for solar installations. Other industry participants are more cautious, attributing much of the increase to seasonal patterns rather than geopolitical anxiety.
China wafer prices unchanged as resumed purchases fail to lift market
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.
Sandia Labs benchmarks PV software providers in first ever blind comparison analysis
Sandia National Laboratories conducted the first-ever blind comparison of seven commercial PV modeling software, revealing that differences in weather handling, system modeling, derates, and assumptions grow as system complexity increases. The study emphasizes that software choice should consider project complexity, workflow, and modeling features rather than relying on rankings alone.
Low new module prices stall growth in secondary solar market
Data from EnergyBin and Buckstop shows used solar modules made up just 1% of resale listings in 2025, as falling prices for new panels weaken reuse economics.
What happens when malware hits PV systems
A random malware variant affected about 800 remote monitoring devices at ground-mounted PV plants in Japan in May 2024. Tokyo-based cybersecurity firm Girasol Energy has told pv magazine what happened and how PV asset owners can protect themselves against such incidents.
EPFL, CSEM achieve world record efficiency of 30.02% in perovskite-silicon triple-junction solar cell
An international research team boosted triple-junction solar cell performance by enhancing perovskite crystal growth, increasing middle-cell light absorption, and adding reflective nanoparticles.
Solarium commissions 1 GW solar module plant in India
Rooftop solar company Solarium Green Energy has commissioned a 1 GW solar module manufacturing facility in Ahmedabad, Gujarat, producing large-format G12 modules up to 725 Wp and serving both internal and external customers.
Thermochromic bifacial PV glazing system for reducing building cooling loads
Researchers in Hong Kong Hong Kong fabricated a thermochromic bifacial photovoltaic glazing system prototype that passively regulates solar heat gain while harvesting energy from both sides. Experiments and simulations showed it significantly reduces cooling loads and indoor temperatures while boosting electricity generation.
Japan publishes new guidelines for flexible solar cell installations
Japan’s New Energy and Industrial Technology Development Organization (NEDO) says its new design and construction guidelines for flexible PV and perovskite solar installations will help ensure the safety and reliability of systems deployed on low-load rooftops and wall surfaces where conventional panels cannot be installed.
