Designed for commercial and multi-residential buildings, the Aqua‑G EVO heat pump can replace gas boilers, cascade up to eight units, and integrate with Panasonic’s complete HVAC ecosystem.

An international research team developed a multi-stage intrusion detection system that uses supervised and unsupervised AI techniques to detect and mitigate cyber threats in smart renewable energy grids. The system can reportedly achieve high accuracy, low false positives, and real-time detection, outperforming traditional intrusion detection system models.

Austria’s photovoltaic market slowed in 2025, with around 1,634 MW of new capacity installed, bringing the country’s total PV capacity to approximately 9.9 GW.

France’s energy regulator has reduced feed-in tariffs (FITs) for PV systems up to 100 kW for the April to July 2026 period, with lower rates across all segments and reduced compensation for surplus electricity.

Researchers found that widely deployed smart meters pose a “massive” cybersecurity risk, potentially enabling data manipulation, energy theft, and service disruption. They propose a new detection method using state estimation and statistical boundaries to more accurately identify cyberattacks, outperforming traditional techniques despite higher computational demands.

Researchers in China demonstrated that integrating energy tower heat pumps with evaporator-side boilers, air-source heat pumps, or solar-assisted systems can significantly improve winter heating efficiency and economic performance in commercial buildings. Among the four configurations tested, the evaporator-side boiler and solar-assisted systems delivered the highest performance and energy savings, offering a sustainable, low-carbon alternative to conventional heating.

In a new weekly update for pv magazine, Solcast, a DNV company, reports that February saw a sharp East Asia solar divide, with southern China and Taiwan experiencing record-high irradiance due to clear skies and low aerosols, while maritime Southeast Asia faced heavy rainfall and below-average irradiance from enhanced tropical convection. The surplus in China was driven by atmospheric cleanliness, whereas Taiwan’s boost came mainly from persistently clear days, contrasting with widespread deficits across Indonesia, the southern Philippines, and nearby islands.

Morocco has published the implementing decree for Law 82‑21, enabling self-producers to consume their own solar power and sell up to 20% of surplus energy back to the grid. The measure, effective 9 June 2026, sets clear tariffs and grid limits.

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.

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.
