Self-consumptionThe number of solar panels depends on an optimal peak power calculated by a sizing study, not on your roof surface. The decisive role of self-consumption and storage.
Self-consumptionA cold store runs around the clock; a rooftop array runs six hours. How to close the gap: self-consumption limits, pre-cooling, and second-life battery storage.
StrategyBefore comparing prices per kWh, a sizing study determines whether battery storage is profitable for your site. Method and key indicators explained.
Market & energyA commercial BESS runs roughly €300–500 per kWh installed. That figure means nothing without the exact scope of the quote and proper site sizing.
TechnicalLoad curve, PV capacity, energy prices, network tariffs: the complete method to size a battery storage system that is actually profitable.
RegulationThe S21 Order of June 2026 reshapes solar buyback according to three power regimes. A breakdown by segment and the implications for self-consumption and storage.
Market & energyEnd of total resale for ≤9 kWp, AOS for 100-500 kWp, 359 hours of negative prices in 2024: decoding the mutation of the solar economic model and the role of battery storage.
StrategyWe're proud to announce a major milestone for Battwoo: nearly €800,000 in support secured through the NextGenerationEU programme, funded by the European Union. This funding will allow us to accelerate the development of our stationary storage technology, built from electric-vehicle batteries diagnosed for a second life.
TechnicalOrientation, tilt, shading: three levers that change photovoltaic output by 30 % or more with the same hardware. Complete method for a B2B project.
RegulationFrance lost 1.6 TWh of solar power in 2025. The CRE reform accelerates PV + storage to boost flexibility, reduce losses, and improve profitability.
RegulationWe are pleased to announce an important milestone: an independent review conducted by VDE Renewables has been successfully completed for our Battwoo Multus energy storage systems, based on a thorough assessment of our technical documentation and operational processes.
Self-consumptionBefore investing in stationary storage, downloading and reading your site's load curve is essential to size a BESS correctly. Method for industrial, tertiary and logistics sites.
TechnicalTechnologies, 2026 prices, efficiency, durability: everything a B2B operator needs to know about solar panels before equipping an industrial, tertiary or logistics site.
