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.

A Japanese joint-pilot will test grid-scale BESS with a range of local and remote attack vectors, with cybersecurity monitoring to watch for indications of anomalies.

Pakistan’s Renewables First has explored the implications of a lack of official data collection from the country’s distributed solar market segment, which is estimated to have reached over 24 GW of installed capacity by the middle of last year.

The latest round of Japan’s carbon financing program, which provides financial support for low-carbon infrastructure projects in partner countries, is backing a 130 MW solar project being built in southeastern Tunisia.

Researchers in Brazil have developed a weighted PV inverter efficiency methodology that accounts for country-specific solar irradiance and operating conditions. The approach is designed to address the limitations of international metrics by incorporating variables such as input voltage and maximum power point tracking (MPPT) performance.

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.

The Nexis solution combines a flexibly configurable hybrid inverter with a modular high-voltage battery offering up to 14 kW charging capacity per stack. The inverter delivers 8–20 kW AC power, supports up to 200% DC oversizing, and features IP65-rated design with integrated backup power.

An international research team boosted triple-junction solar cell performance by enhancing perovskite crystal growth, increasing middle-cell light absorption, and adding reflective nanoparticles.

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.

The Italian heating solutions provider said its new Nuos Plus S2 Wi-Fi heat pump system offers up to 80% energy savings and a coefficient of performance of up to 3.51.
