1. Power Generation: <\/strong>According to data from MARSTEK\u2019s proprietary EMS platform, a 1000W solar panel in southern Germany can generate up to 1160 kWh annually. This product supports up to 4000W of solar panels, resulting in 1160 \u00d7 4 = 4640 kWh\/year. Annual energy storage capacity: 15.36 kWh \u00d7 365 = 5606.4 kWh. 2. Calculation Assumptions: <\/strong>Self-consumption rate is 85% (source.<\/a>); Fixed electricity price: \u20ac0.40\/kWh; Peak-valley price difference: \u20ac0.132\/kWh. Every 1 kWh of solar power reduces CO\u2082 emissions by approximately 0.997 kg. 3. Calculation Details: <\/strong>Annual Electricity Cost Savings. = Savings from self-consumption + Savings from AI-optimized charging. = 4640 kWh \u00d7 85% \u00d7 \u20ac0.40. + (5606.4 kWh \u2212 4640 kWh \u00d7 85%) \u00d7 \u20ac0.132 \u2248 \u20ac1797<\/strong>.
