Bill Savings, Carbon Cuts: Up to €1,797 per year and 3,932 kg CO₂.
1. Power Generation:
According to data from MARSTEK’s 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 × 4 = 4640 kWh/year.
Annual energy storage capacity: 15.36 kWh × 365 = 5606.4 kWh.
2. Calculation Assumptions:
Self-consumption rate is 85% (source.);
Fixed electricity price: €0.40/kWh;
Peak-valley price difference: €0.132/kWh.
3. CO₂ Reduction:
Every 1 kWh of solar power reduces CO₂ emissions by approximately 0.997 kg.
4. Disclaimer:
All data is based on ideal test conditions; actual results may vary depending on individual circumstances.
Calculation Details:
Annual Electricity Cost Savings
= Savings from self-consumption + Savings from AI-optimized charging
= 4640 kWh × 85% × €0.40
+ (5606.4 kWh − 4640 kWh × 85%) × €0.132
≈ €1797
Estimated CO₂ Emission Reduction
= 4640 kWh × 85% × 0.997
≈ 3932 kg
