Residential PV

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.

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.

China’s 2026 to 2030 policy plan elevates clean electricity as a central driver of economic growth, with greater emphasis on system integration and industrial use.

Analysis from GlobalData finds the UAE’s cumulative solar capacity increased from 5.7 GW to around 6.7 GW last year. The country’s annual solar deployments are forecast to increase in the coming years, with 20 GW of installed solar expected by the end of the decade.

Researchers analyzed 16 years of data from over 1 million PV systems in Germany and found annual degradation is just 0.52–0.61%, roughly half prior estimates. Environmental factors like heat, frost, and air pollution affect performance, while smaller systems degrade less than larger ones, boosting long-term reliability and profitability.

The Chinese manufacturer said its new Nex E6000 and Nex E6000H storage systems combine a 6 kWh battery, an inverter, and an integrated energy management system, with scalable design allowing multiple units to be networked for higher capacity and coordinated energy sharing.

Roth Capital Partners says it expects a sharp drop in US residential solar installations as tax credit changes and Foreign Entity of Concern (FEOC) rules constrain financing.

The K2 MultiRail High mounting system is a one-piece elevated solution with a height of 100 mm tailored to improve rear ventilation on metal roofs. K2 Systems says greater distance between modules and metal roof surface improves airflow and lowers module temperature, which can translate to higher annual energy yield.
