A new report from global energy think tank Ember shows 814 GWdc in new solar and wind capacity was installed in 2025, but the pace of wind deployment rose 47% year-over-year compared to just 11% for solar.

The TOPCon solar cells fabricated with screen-printed, fire-through copper rear contacts and silver front contacts, using laser-enhanced contact optimization (LECO) to significantly reduce contact resistivity. Optimized copper cells achieved 24.3% efficiency, comparable to Ag-contacted cells, with excellent stability.

An international study has demonstrated that utility-scale solar PV paired with hydraulic hydro storage (HHS) could reach an LCOE as low as $0.022/kWh in select U.S. regions. The system could provide GWh-scale, cost-competitive, and highly reliable long-duration storage, capable of powering large commercial districts with minimal environmental impact.

Scientists in Australia claim that TOPCon cells are rapidly closing the open-circuit voltage gap with heterojunction counterparts, now under 10 mV, while offering greater wafer tolerance and high industrial scalability. Despite slightly lower efficiency, TOPCon-based perovskite/silicon tandems can achieve a levelized cost of energy comparable to heterojunction-based tandems due to reduced fabrication costs, according to the researchers.

Cornell University researchers demonstrated that tracking solar panels in agrivoltaic systems can protect crops from wind damage while allowing airflow, outperforming traditional single-row tree windbreaks. They also proposed a new lowered-first-row panel design that improves wind protection, achieving up to 86% reduction in shelter-zone wind speeds under extreme conditions.

Researchers in Canada found that semi-transparent cadmium telluride and low-transparency crystalline silicon solar panels can boost turnip root and leaf yields in agrivoltaic systems by optimizing light quality, distribution, and heat stress. Their study highlights that PV module type, transparency, and spectral transmission must be carefully matched to plant physiology to maximize both crop productivity and renewable energy generation.

The company’s fourth annual snapshot report highlights an industry transitioning from incentive-driven growth to a focus on affordability and resilience. Third-party ownership is becoming the preferred financing method as consumer concerns over upfront costs and policy changes reshape the residential market.

Sandia National Laboratories conducted the first-ever blind comparison of seven commercial PV modeling software, revealing that differences in weather handling, system modeling, derates, and assumptions grow as system complexity increases. The study emphasizes that software choice should consider project complexity, workflow, and modeling features rather than relying on rankings alone.

U.S. researchers developed a framework showing that wider spacing between solar PV rows can make agrivoltaic systems economically viable for large-scale mechanized farming. Their simulations in Colorado demonstrated that optimized row spacing maintains crop production while improving combined agricultural and energy revenues.

McGill University researchers, publishing in Communications Earth & Environment, used deep-learning computer vision to analyze 719 solar projects across the Western U.S. The study establishes a new “land-sparing” benchmark, providing developers with precise data to balance rapid capacity expansion with conservation and land-use priorities.
