Sunnic Lighthouse says Germany’s first prequalified secondary control reserve solar project shows how quickly PV assets can be moved into advanced grid services markets. November 17, 2025 Jochen Siemer By pv magazine Germany Enerparc subsidiary Sunnic Lighthouse, flexibility provider Entelios and transmission system operator 50Hertz completed prequalification for the 37.4 MW Schkölen solar park in Thuringia, Germany, to participate in the secondary control reserves market. The plant has provided up to 25 MW of positive and negative automatic frequency restoration reserve in the past week. Photovoltaic assets have not previously participated in Germany’s secondary reserve segment. The companies said the…

ESI Motion has announced SatBat, a new battery designed for low Earth orbit spacecraft. SatBat integrates a heating and battery management system, aiming to improve energy storage and management in orbital environments. The battery leverages ESI Motion’s expertise in radiation tolerant electronics and power management. It delivers high power density, thermal stability and advanced battery control, setting the standard in space systems. SatBat weighs half as much as typical lithium-ion space batteries and offers twice the usable capacity and operational life. After a four-year LEO mission, it retains 98 percent of its original payload. “SatBat represents a quantum leap in…

Puerto Rico has reached 1.3 GW of residential solar and 185,000 residential batteries, while Wood Mackenzie expects an additional three GWh of residential storage by 2029. Utility-scale solar and storage projects are taking off, as described by a McConnell Valdés attorney. November 17, 2025 William Driscoll By pv magazine USA Nearly 90 MW of residential solar power was added in Puerto Rico from July through September, said Max Issokson, a senior research analyst. at Wood Mackenzie, based on data from utility Luma Energy. That represents the U.S. territory’s second-best quarter ever, he said. Issokson spoke at the annual conference of…

Vermont utility Green Mountain Power (GMP) announced it has selected Enphase Energy to join the company Home battery leasing program where customers have backup power when they need it and share stored energy during peak hours. GMP’s battery leasing program is a key component of the growing 75 MW Virtual Power Plant, which is now Vermont’s largest dispatchable energy source and peaking facility, reducing costs for all GMP customers while increasing resiliency and grid flexibility. “We are excited to partner with Enphase to bring cutting-edge technology directly to our customers – strengthening the network, improving reliability and reducing costs,” said…

The Instrumentation and Industrial Electronics research group of the University of Cordoba has implemented a sensor-based system for monitoring solar power plants. This network collects energy and meteorological data every tenth of a second. The team applied new software implementations to existing measurement equipment, referred to as Extended Phasor Measurement Units. These units record detailed parameters including current, voltage, frequency and solar radiation. Monthly data output reaches two to three gigabytes, as a result of the fine-tuned synchronization of the devices across multiple solar locations. The data collected supports performance analysis and short-term forecasting of plant production. It also aims…

In a new weekly update for pv magazineSolcast, a DNV company, reports that the end of spring in the Northern Hemisphere is creating favorable conditions for solar power generation in key markets in the United States, China and Europe. November 14, 2025 Solcast Seasonal forecasts through late spring in the Northern Hemisphere indicate favorable conditions for solar power generation in key markets in the United States, China and Europe, according to analysis using the Solcast API. Despite regional differences, especially in China, large-scale solar operators in all three regions can generally expect above-average irradiance during the critical months of the…

Photo: DOE In the United States, energy demand is rising after decades of stagnant growth, driven by electrification efforts, data centers and artificial intelligence. As demand increases, the economy continues to favor wind and solar energy, which consistently rival gas and coal in terms of affordability. As rural communities look to increase renewable energy, a unique opportunity presents itself. Flat, sunny and easily accessible land that is ideal for solar parks is often already in use for agriculture. A new one report from the Institute for Energy Economics and Financial Analysis (IEEFA) highlights the opportunity to expand the use of…

Researchers in China have improved the performance and durability of inverted perovskite solar cells by creating two new 56pi electron fullerene derivatives, known as C60-TFB and C60-TFP, for use as electron transport layers. The research team synthesized C60-TFB and C60-TFP via a 1,4-asymmetric addition approach, giving the molecules bulky tert-butyl, indole and azaindole groups. These groups prevent dimerization when exposed to light and provide a strong bond with the perovskite layer, resulting in fewer defects. The resulting electron transport layer forms an effective barrier to stop the migration of iodide ions from the perovskite layer and silver atoms from the…

The Ihma Dam solar project is South Korea’s largest floating PV installation, located next to a multifunctional dam. The project has a resident participation model that allows those living within a radius of one kilometer to share the profits from the power supply. November 14, 2025 Patrick Jowett The Ihma Dam floating solar power plant with a capacity of 47.2 MW has been put into operation South Korea. Located at the Imha Dam east of Andong city in Gyeongsangbuk-do Province, the solar array is the largest floating PV installation located next to a multi-purpose dam in South Korea. The dam…
