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.
