Swiss power distributors allowed to remunerate solar power at market rates Switzerland will allow grid operators to remunerate photovoltaic electricity at real-time market prices from 2027, aiming to better align solar feed-in with demand. Small PV systems will be protected by a minimum remuneration premium, while storage and local consumption are expected to become more important under the new model.

EVs equipped with vehicle-integrated PV could cover up to 80% of their electricity needs A research project led by Fraunhofer Institute for Solar Energy Systems ISE has demonstrated that vehicle-integrated photovoltaics (VIPV) can significantly reduce strain on power grids. The concept is particularly relevant for the logistics sector, where trucks require large amounts of electricity for cooling, heating and auxiliary systems, while also offering extensive roof space for PV integration.

Inverter protection system triggers permanent short circuit in under 1 millisecond A German research team has developed a semiconductor-based protection concept tailored to renewable energy systems that forces a permanent short circuit in less than 1 millisecond in the event of a fault. The generated short circuit remains intact during the fault, reliably protecting the components from overcurrent.
