    Common scenarios:

    💡 Quick Tips:
    • • Residential: ~3-10kW peak, 8,000-30,000 kWh/year
    • • Small commercial: ~20-100kW peak, 50,000-500,000 kWh/year
    • • Load factor = Annual kWh ÷ (Peak kW × 8760)

    Solar Generation Data

    Solar Storage requires solar generation data to calculate self-consumption and export revenue optimization

    Tariff Information

    Tariff rates are needed to determine savings from time-shifting and export revenue

    Expected Benefits:
    • •Reduce grid imports during peak rate periods
    • •Maximize solar self-consumption (typically 70-90%)
    • •Earn revenue from exporting stored solar energy
