Legacy solar models focused on daytime production, but the shift to battery-driven self-consumption is creating a performance gap that puts long-term ROI at risk.

A group of researchers from the Polytechnic University of Cartagena and the University of Castilla–La Mancha studied real-life self-consumption photovoltaic installations that reflect the current ...

A survey of more than 800 Spanish C&I PV installations following the 2019–2022 self-consumption boom found significant ...

Cumulative solar PV self-consumption in Spain reached 9.3GW at the end of 2025. Image: Bill Mead via Unsplash. The rate of installation of new self-consumption PV systems in Spain fell slightly last ...

Until 2009, German PV system owners hardly used any of the electricity they generated themselves, as the feed-in tariff for photovoltaic electricity was higher than the price of electricity purchased ...

‘With a grid feed-in of just under 60TWh, self-consumption in 2024 accounts for 17% of net electricity generation from photovoltaics,’ the researchers said. Image: Fraunhofer ISE. High power prices ...
