Phnix unveils indoor monobloc heat pump for space‑constrained urban retrofits
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.
Japanese scientists build near-white heterojunction solar cell for BIPV applications
The lab-scale, near-white heterojunction solar cell uses nanoclay-based scattering layers combined with dielectric multilayer films to preserve power conversion efficiency while enhancing visual appeal. The researchers report optical losses of less than 1% at a 50% clay volume fraction, which are significantly lower than those observed with textured glass.
Solar electricity during night-time
Night-time in solar PV systems averages 16 hours, requiring significant storage or alternative generation to meet demand. Pumped hydro and batteries are key, with pumped hydro offering long-duration, low-cost storage for cloudy or windless periods. Complementary strategies include wind power, load shifting, and dispatchable generation, while high solar and wind penetration reshapes grid operations and pricing.
U.S government sets preliminary countervailing duties on solar imports from India, Indonesia and Laos
The U.S. Department of Commerce has issued preliminary findings that solar manufacturers in India, Indonesia and Laos benefited from government subsidies, paving the way for countervailing duties of up to 143.30%.
First Solar announces licensing agreement with Oxford PV, alleges new TOPCon patent infringements
The U.S. thin-film solar module manufacturer’s stock price fell more than 12% in extended trading following the earnings announcement, partly due to lower-than-expected guidance for 2026 sales and revenue.
Vattenfall to combine wind and solar with new connection concept
Vattenfall says it will connect a 7.6 MW solar plant to a 17 MW wind farm in Germany, allowing both to operate through a single grid connection point.
‘Garbage in, garbage out’ – solar industry debates reality of AI
Artificial intelligence can accelerate the planning, construction, and operation of photovoltaic systems, as shown at the recent Solar Quality Summit in Barcelona, Spain. But its effectiveness depends on data quality, as poor data, unclear responsibilities, and weak documentation can become major cost drivers.
How to protect animals from lightning in agrivoltaics
Researchers in Germany assessed lightning risks in livestock-integrated agrivoltaic systems, identifying key injury mechanisms and establishing safe step and touch voltage limits. Their simulations showed edge strikes and conductive structures pose the highest hazards, highlighting the need for livestock-specific earthing designs and mitigation strategies.
When hail hits PV: New research maps damage, testing, and mitigation
A new review examines the impact of large hail on PV systems, covering damage, testing methods, and mitigation strategies. Researchers highlight risks across Europe and the U.S. and explore ways to improve module resilience.
Solar module prices rise faster than expected in February
Solar module prices increased by €0.01 ($ 0.012)/W to €0.015/W in February, lifting levels 15% to 18% above the December 2024 low despite falling wafer costs, as manufacturers seek to restore margins after prolonged losses.
