Premier Energies unveils 600-630 W all-black TOPCon solar modules
The Indian manufacturer said its new all-black panel series features a power conversion efficiency of up to 23.32% and a bifaciality factor of up to 85%.
Oxford PV says tandem solar could add up to 5 km to daily EV range
Oxford PV has joined Nissan’s SUITE consortium, advancing perovskite-silicon tandem solar tech that could boost vehicle-integrated solar EV range by an additional 3–5 km per day and push total daily solar driving range toward 15–20 km.
UK startup showcases all-in-one water cylinder heat pump prototype
Nusku has developed a prototype of a fully integrated air-source heat pump system that combines the heat pump with a hot water cylinder and controls into a single outdoor unit. The design aims to simplify installation and reduce space requirements by replacing separate indoor and outdoor components with one pre-packaged system.
Chinese scientists build silver-free heterojunction solar cell with 25.2% efficiency
The research team developed a plasma interface engineering method to improve indium tin oxide layers, solving adhesion, contact resistance, and stability issues for copper electroplating. The optimized process enabled uniform copper metallization and boosted device efficiency to 25.2%, significantly outperforming untreated reference cells.
Two-year testing shows how PV plants increase local temperatures in semi-arid regions
A two-year field study in a 100 MW photovoltaic plant in semi-arid Inner Mongolia combined ground-based sensors, radiation measurements, and UAV thermal imaging to quantify how large-scale PV installations alter local air temperature, surface temperature, and energy balance compared with nearby non-PV areas. Results show consistent site-scale warming of 0.8 C.
New Zealand’s grid operator finds emerging energy gap in early 2030s
Transpower’s latest assessment of New Zealand’s balance between electricity supply and demand suggests an energy gap could emerge in the early 2030s, even if all committed and likely investments are delivered without delay.
Chinese solar exports surge 125% in March on policy change rush, not underlying demand acceleration
The Chinese customs data show a March surge as buyers rushed shipments ahead of April’s tax-rebate change.
Pakistan plans to scrap licensing fee for PV systems up to 25 kW
The move seeks to reverse aspects of the Nepra Prosumers Regulations 2026, which centralized approvals and is creating delays and financial barriers for rooftop solar adoption.
Key takeaways from Austria’s Solar Solutions
Around 100 exhibitors presented their products at the Vienna trade fair. Visitor numbers were limited, partly because the event coincided with the launch of the first funding call for photovoltaic systems and storage this year.
Record solar, wind surge drives 3.3% drop in India’s fossil generation in 2025
India’s renewable power generation from solar, wind, hydro and bioenergy rose by a record 98 TWh (+24%) in 2025, driven by strong growth in solar and wind, according to Ember. The increase was twice the country’s electricity demand growth of 49 TWh, which was relatively low due to milder temperatures and slower industrial activity. As a result, India’s fossil power generation fell by 3.3%.
