New York Power Authority renewables plan shows financial challenges for building solar
The levelized cost of building a solar project in New York far exceeds the expected revenue from selling solar power, says a NYPA plan, with project success potentially depending on the sale of renewable energy credits at a satisfactory price.
Solar and storage program forecast to save all Massachusetts ratepayers $313 million per year
Solar plus storage can also offer winter reliability improvements and limit gas consumption, finds a report from Synapse Energy Economics and the Solar Energy Industries Association.
Remote sensing-based tech for hourly snow-induced PV power losses assessment
A team of Sweden-based researchers has developed a snow loss model to estimate snow-induced PV power losses on an hourly basis. The proposed approach relies solely on data from remote sensing sources, such as aerial imagery, LIDAR, and satellite data.
Aiko achieves 34.76% efficiency for 2-terminal perovskite-silicon tandem solar cell
The Chinese manufacturer said its 2-terminal 34.76%-efficient perovskite-silicon tandem lab-scale cell is based on heterojunction technology and developed by a collaboration of Solarlab Aiko Europe, Aiko headquarters, and its R&D in Yuwi, China.
Dutch regulator finds grid fees for rooftop solar are reasonable
The Dutch competition regulator rules feed-in costs for home solar are not unreasonable. It is calling on energy suppliers to charge feed-in costs uniformly to make it easier for consumers to compare contracts.
Building resilience amid intensifying weather events
In its latest monthly column for pv magazine, IEA PVPS shows that with climate-specific site selection, robust design, proper installation, and proactive O&M, most PV systems can be made resilient and remain reliable despite intensifying weather risks.
Tracks of low-pressure systems split Europe’s solar performance in November
In a new weekly update for pv magazine, Solcast, a DNV company, reports that Europe’s solar generation potential in November showed a strong east–west split, with Eastern Europe experiencing 15–20% below-normal irradiance due to persistent storms, while much of Western and Central Europe recorded 15–20% above-average levels under clearer conditions. The Atlantic coast was an exception, as Storm Claudia reduced irradiance to near or below average in Portugal, the British Isles, and parts of France and Spain.
Solar, wind and storage: stable prices, stable grid
In its latest monthly column for pv magazine, the International Solar Energy Society (ISES) explains how Australia’s rapid expansion of solar and wind energy has not increased wholesale electricity prices, which have remained stable since 2016. Rooftop solar, now widespread and highly cost-effective, provides the country with resilient, low-emission power, making all-electric homes increasingly independent from the grid.
India passes 132.8 GW of installed solar capacity
India’s installed solar capacity reached 132.85 GW at the end of November 2025, led by utility-scale projects in Rajasthan, Gujarat and Maharashtra, according to the central government.
Ambrion launches new all-in-one storage solutions
The Australian firm has introduced single-phase 5 kW and 6 kW AC output storage systems, as well as three-phase 10 kW and 12 kW models. Storage capacities of the new products range from 5 kWh to 40 kWh.
