Configuring a suitable solar energy storage system requires comprehensive consideration of household electricity needs, sunlight conditions, and economic feasibility. This includes the following steps:
Power Consumption Calculation: Determine the system capacity based on the household's average daily electricity consumption. It's generally recommended that the energy storage capacity match 70% of the household's average daily electricity consumption (e.g., 5kWh can meet the nighttime electricity needs of a household of 3-4).
Power Usage Scenario Analysis: Villa users should consider high-energy consumption scenarios such as smart homes and entertainment devices to ensure the system can cover both daily and special needs.
Equipment Selection
PV Panels: B-type double-glass panels are preferred, suitable for rooftop installation.
Energy Storage Batteries: Lithium iron phosphate batteries (cycle life ≥ 6000 cycles) are recommended, with capacity configured as needed (e.g., 5kWh can meet nighttime electricity needs).
Energy Management: Bidirectional inverters with an efficiency of ≥ 97%.
