Bluetti launches EnergyPro 13K home storage system in US
Chinese battery manufacturer Bluetti has launched its next-generation whole-home battery backup system in the United States, introducing the EnergyPro 13K Energy Storage System (EP13K).
Solar-plus-storage could meet 90% of India’s power demand
Ember sazs that solar paired with battery storage could supply 90% of India’s electricity demand at a levelized cost of electricity (LCOE) of INR 5.06/kWh ($56/MWh).
Titanium emerges as a vanadium alternative for redox flow batteries
A Japanese–Chinese team developed a titanium molten salt redox-flow battery using abundant titanium ions and molten salt electrolytes to enable high-voltage, fast, and stable grid-scale energy storage. The system demonstrates high efficiency of over 97%, strong cycling stability, and improved cost and scalability compared to vanadium-based batteries, with further optimization underway.
Bangladesh plans 442 MW solar facility near coal power plant
The Bangladesh Power Development Board plans to build a 442 MW solar plant near the Rampal Power Station with a $200 million investment, targeting the country’s largest installation and lower tariffs than comparable projects.
Spark secures Australian approval for massive solar and battery project
Spark Renewables has secured final state planning approval for a solar and battery project that will add 800 MW of PV and 356 MW/1,574 MWh of energy storage capacity to the grid in New South Wales, Australia.
Solar keeps slimming down while power rises
An international study found that the specific power of commercial silicon solar modules increased from 8.5 W/kg in the early 2000s to 23.6 W/kg today, driven by advances in module design, bifaciality, and temperature management. The researchers highlighted that glass and framing dominate module weight, and considering operating conditions like nominal operating cell temperature and rear-side illumination is essential for accurate PV system design.
Inverter-based resource performance history leads to US regulatory change
Three new NERC standards — PRC-028, 029 and 030 — are designed to improve grid reliability
Switzerland deploys 1.52 GW of solar in 2025
Switzerland’s photovoltaic market slowed in 2025, with newly installed capacity falling 15% to 1,526 MW, according to Swissolar. Despite the decline, growth in residential storage, building electrification, and EV integration points to a gradual market recovery.
Inpow unveils 587 Ah semi-solid-state storage cell
Inpow Battery has launched a 587 Ah semi-solid-state storage cell with safety-focused design features, while outlining plans for a 6.5 GWh production line.
AI-enabled hacks expose remote shutdown risk in microinverters
IT security firm Jakkaru has identified a vulnerability in microinverters from AP Systems that could enable a “kill switch” scenario, potentially shutting down tens of thousands of inverters simultaneously and disrupting grid operations.
