1. What is included in the solar energy system? - The ESS06 includes PV modules, MPPT controller, LiFePO4 battery, DC cables, and BIPV mounting hardware. An inverter may be needed depending on AC load configuration.
2. How much roof space is needed for 20kW? - With 580-740W panels at 2279x1134mm each, approximately 30-35 panels are needed, requiring roughly 80-100m² of roof or ground space depending on panel wattage selected.
3. Can the system reduce my electricity bill to zero? - With proper sizing, solar self-consumption, and battery storage, the ESS06 can significantly reduce or eliminate grid electricity costs. Actual savings depend on local solar irradiation and consumption patterns.
4. What maintenance does the system need? - Periodic panel cleaning and annual inspection of electrical connections are recommended. The LiFePO4 battery is maintenance-free. System design life is 15-20 years.
5. How is the system shipped internationally? - All components are UN38.3 and MSDS certified, packed in dangerous-goods-compliant wooden crates for safe sea or air freight worldwide.
