Germany adds 6.57 GWh of battery storage in 2025, total hits 24 GWh
Germany added an estimated 6.57 GWh of stationary battery storage capacity in 2025, an increase of about 8% year on year, lifting total installed capacity to roughly 24 GWh. Growth was driven by industrial and large-scale systems, even as home storage installations declined alongside weaker rooftop solar demand.
Danish researchers develop color-tunable BIPV foil
The use of a novel roll-to-roll process and optimization technology resulted in polymer foils for use in colored PV modules in a potentially wide range of colors with low iridescence and low levels of efficiency loss.
US would reach 100% renewable energy by 2148 at current pace
China is on track to reach a fully renewable energy system by 2051, nearly a century earlier than the United States, according to a global study covering 150 countries.
India’s solar capacity additions on track in 2025, says SBICAPS
India added an estimated 40 GW of solar capacity in calendar year 2025, driven by utility-scale projects and rooftop growth. Energy storage tendering also picked up pace.
Voices of leadership: How inclusion is powering innovation forward
This article of the Women in Solar+ Europe series brings together experts and leaders featured throughout 2025 to reflect on why leadership must be redefined for today’s realities. Their insights highlight inclusion not as an add-on, but as the very heart of effective, future-ready leadership.
China to abolish solar export tax rebates in April
China will scrap value-added tax export rebates for PV products from April 1, 2026, while cutting battery rebates ahead of a full phaseout, raising export costs for manufacturers and potentially pulling shipments forward into early 2026.
The Hydrogen Stream: RWE commissions 100 MW hydrogen electrolyzer
RWE has started commissioning a 100 MW electrolyzer in Germany to supply renewable hydrogen under long-term contracts, while Hydrogen Utopia International and Hydrogen Systems are advancing plans to build waste-to-hydrogen plants in Saudi Arabia.
Malaysia launches new net metering scheme for rooftop PV
Effective since January 1, 2026, the Solar Accelerated Transition Action Programme (Solar ATAP) aims to build on Malaysia’s previous net metering program’s efforts to maximize the use of rooftops for solar generation by incentivizing consumers to export excess generation to the grid. The capacity limit has been set at 100% of the consumer’s maximum demand, or 1 MW.
Sodium-ion battery cells already near lithium-ion cost parity, set to get cheaper
By 2050, sodium-ion batteries with fast learning rates could deliver storage at 11–14 €/MWh – cheaper than lithium-ion at 16–22 €/MWh – while also offering higher energy-to-power ratios and high cycle durability, a new research finds.
How to avoid ‘long tail’ effects in large-scale PV plants
New UNSW research found that about 20% of solar modules in large PV plants degrade much faster than expected. They recommend holistic strategies such as robust materials, advanced designs, and proactive monitoring to decouple degradation pathways and prevent cascading failures.
