The UK-based manufacturer has expanded its Ecomod 290HT range with a new 65 kW monobloc air-source heat pump using R290 refrigerant, offering flow temperatures up to 70 C, a COP of 4.6, and cascade capability of up to 7 units.

Whatever decision the U.S. Department of Commerce makes on polysilicon imports, some market segments are in for a bumpy ride in 2026 as the expiration of tax credits and other policy levers change the trading environment faced by residential installers and others. Jesse Pichel and Lev Seleznov of Roth Capital assess what lies ahead for U.S. solar.

With Latvia’s cumulative solar capacity reaching 920 MW by end of 2025, the Latvian Renewable Energy Alliance says the 1 GW threshold may now have been surpassed. The country also appears on track for a record year in solar deployment this year, as some of the largest projects in the pipeline materialize. 

Ireland reached 2,345 MW of installed solar capacity by December 2025, more than tripling installed capacity since 2023, according to Solar Ireland data. The country’s development pipeline has currently reached 1.7 GW.

Official data from Morocco’s National Office of Electricity and Drinking Water puts the country’s cumulative utility-scale solar capacity at almost 1.3 GW, while import data suggests there could be a further 3 GW of operational solar spread across the commercial and industrial, solar pumping and residential solar markets.

German startup Solarsecure Tech has introduced a gateway designed to decouple PV inverters from manufacturer clouds and block unauthorized remote control commands.

Germany’s Fraunhofer Institute for Energy Economics and Energy System Technology IEE (Fraunhofer IEE) says in a new position paper that large-scale battery storage systems in medium-voltage grids should be technically prepared for future grid-forming operation, aiming to bridge the gap between current regulations and potential system stability requirements.

A systems approach is essential for smart energy standardization, ensuring interoperability, avoiding overlaps, and addressing complex interactions across the grid, appliances, and infrastructures. The IEC System Committee for Smart Energy (SyC SE) applies system-level thinking, using tools like reference architectures and roadmaps to coordinate standards, support innovation, and tackle emerging areas such as EV integration, digital twins, and zero-emission technologies.

The Chinese manufacturer said its new airMono indoor monoblock heat pump is tailored for space‑limited urban retrofits, providing heating, cooling, and domestic hot water without an outdoor unit. The system’s coefficient of performance ranges from 2.5 to 4.1, while the seasonal coefficient of performance spans 4.5 to 4.7.

Late amendment put forward to halt sudden retroactive change to export rates for net metering contract holders in Pakistan. It follows strong criticism from local solar industry leaders over sudden change in export rates under new net billing structure.
