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 Madrid and the Centre for Energy, Environmental and Technological Research (CIEMAT) have analyzed the potential self-sufficiency of ...
A survey of more than 800 Spanish C&I PV installations following the 2019–2022 self-consumption boom found significant ...
Scientists have developed a hybrid energy storage system combining lithium-ion batteries with power-to-heat-to-power thermal batteries (PHPS), cutting energy costs by 7 percent and boosting solar self ...
The decrease was driven by the industrial sector, as the residential segment rose due to the Iberian blackout in April. Image: Bill Mead via Unsplash. For the third year in a row, self-consumption ...
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 ...
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 ...
