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.

A 620 MW solar project to be constructed in South Africa’s Free State has reached financial close. The milestone follows the signing of a more than 20-year multi-offtaker wheeling agreement with commercial and industrial clients. 

Iran is widely known for its oil and gas resources, but its strongest long-term energy asset may be the sun. New research shows how solar PV could drive a cost-competitive transition across power, heat, transport, industry, and desalination, while opening the door to a broader Solar-to-X Economy.

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.

Lithuania-based Refra has launched its Oasis series of water-to-water heat pumps and chillers, offering capacities from 34 kW to 600 kW for small to large commercial and industrial applications. Featuring propane refrigerant, inverter-controlled compressors, and modular multi-circuit design, the units can reach a coefficient of performance of up to 5.1.

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.
