When heat becomes a stress test: What extreme temperatures mean for photovoltaic systems and battery storage

Photovoltaics rely on sunlight. Battery storage systems rely on absorbing and releasing energy precisely when the power grid needs it. Both sound like an ideal combination for hot summer days: plenty of sunshine, high generation, increased electricity demand due to cooling, and greater grid flexibility. In practice, it’s more complex. The post When heat becomes a stress test: What extreme temperatures mean for photovoltaic systems and battery storage appeared first on pv magazine Global .

Australian grid operator announces curtailment drill for rooftop PV

South Australia’s grid operator will complete its annual test of its ability to temporarily curtail rooftop solar generation on August 25. Solar systems in the state will be curtailed for up to one hour, expected to cause the loss of around 1.5 kWh of generation per installation.

The summer solar carried the water

Europe’s hydro fleet produced less power in the summer of 2026 than it did in the drought summer of 2022, and reservoir stocks finished the period 7.7% below their eleven-year median with France under its historical floor. Over those same four years solar generation across the affected systems rose by 39 TWh. That surplus is now visibly reorganizing the rest of the fleet: reservoir hydro has withdrawn from the middle of the day, and pumped storage has moved its charging window from the pre-dawn hours into the middle of the day, with the peak charging hour shifting from around 04:00 to between 13:00 and 14:00, and the correlation between hourly solar output and hourly pumping rising from zero to 0.86 in six summers.

Even at 100 meters, PV makes neighbours more likely to go green

Research from Switzerland finds homeowners whose neighbors install a solar system become more likely to install a solar system themselves, adopt an electric vehicle and reduce their electricity consumption.
