Picea delivers energy autonomy by combining short-term battery storage (25 kWh) with long-term hydrogen storage (1,500 kWh). Excess solar energy is stored as hydrogen during summer, which is converted back to electricity and heat in winter. The system’s predictive energy management optimizes energy flows, ensuring self-sufficiency even during extended periods of low solar irradiation. With over 100 times the storage capacity of conventional home batteries, Picea enables households to meet 100% of their energy needs without grid reliance. The Picea app allows users to monitor real-time energy usage and adjust settings for maximum autonomy, including reserving hydrogen for emergencies.
