Sodium-ion cells launched for energy storage by another Chinese mid-tier battery company
Bosa Energy in Hubei, China, has launched sodium-ions cells for stationary energy storage, with a volumetric energy density of 206 Wh/L
Lithuania’s solar capacity surpasses 3 GW
Lithuania added approximately 600 MW of solar last year, taking total capacity to 3,040 MW. Technical permits have been issued for an additional 4 GW of solar but with grid congestion becoming a primary constraint, future deployments will be increasingly dependent on integration with storage technologies.
PV, storage to anchor Ireland’s first co-located data center campus
Due for completion in 2028, the DUB20 data center campus in County Wicklow will feature battery energy storage and solar PV installations capable of generating 6,000 MWh annually. It will be Ireland’s first Green Energy Park, delivered as part of its large energy users action plan (LEAP).
Portable data centers target curtailment, grid constraints
Australian startup WinDC has partnered with US-based Armada to deploy modular data centers at renewable energy sites, aiming to reduce curtailment and meet rising demand for energy-intensive computing infrastructure.
Japan’s Kyocera, Cosmo Energy units enter solar, wind PPAs
Kyocera Corporation will begin to supply electricity generated from its solar assets to Cosmo Energy Solutions from next month. It has also entered into a separate power purchase agreement with Cosmo Eco Power for energy generated from a 48 MW wind farm.
Pushing perovskite solar cells to the ultimate thickness limit
Researchers in Singapore have developed fully vacuum-processed ultrathin perovskite solar cells with absorber layers as thin as 10 nm, achieving high transparency and stable efficiencies up to 12%. These cells balance optical transparency and electrical performance, offering scalable, design-flexible photovoltaics suitable for seamless integration into buildings.
Indonesia’s path to 100 GW of solar
A study from the Institute for Essential Services Reform and Indonesia’s Coordinating Ministry for Economic Affairs explores how Indonesia can turn its target of deploying 100 GW of solar from mandate to mobilization.
Tongwei moves into hybrid heterojunction back contact solar cell technology
Tongwei is partnering with GS-Solar and Golden Solar to develop a large-scale manufacturing facility for hybrid heterojunction back-contact (HBC) solar cells that combine heterojunction passivation, tunneling oxide and polysilicon structures used in TOPCon designs, and the grid-free front-side architecture typical of back-contact technologies.
Beware of cleaning photovoltaic panels with dishwashing detergent
Researchers in Finland found that dishwashing liquid reduces solar module transmittance and performance, leaving residues even after rinsing. They recommend avoiding its use for cleaning solar panels.
DIY plug-in solar shows $0.65/W potential in US market
Achieving a system cost of $0.65/W through the secondary market and do-it-yourself assembly demonstrates a viable pathway for US plug-in solar to provide immediate utility bill relief to renters and apartment dwellers.
