  • Transcript

    • 1. Unit 15 Dimensioning of a Solar/Battery Backup system Developed by: Alberto Escudero Pascual. IT+46
    • 2. Agenda
      • What is dimensioning?
      • User requirements and input data
      • Solar dimensioning
      • Battery dimensioning
    • 3. What is dimensioning?
      • What do I need to cover my needs in terms of electricity?
        • How many solar panels?
        • How many batteries?
      • What voltage/current do I want to obtain?
        • What is my load?
    • 4. Location Based Data
      • Sun peak hours/day
        • Depending on your location
        • Plan for the worst!
      • Nigeria: 4 sun peak/day
    • 5. User requirements
      • Power consumption
        • Total consumption of all electrical devices
      • Anatomy
        • How many days should the system work without power input?
    • 6. Equipment specification
      • Battery
        • Capacity (Ah)
        • Max discharge (%)
        • Voltage (V)
      • Solar Panels
        • Nominal power (W)
    • 7. Example
      • Power Consumption (load): 120 W
      • Battery
        • Voltage: 12V
        • Capacity: 100 Ah
        • Max discharge: 50%
      • How many batteries do we need?
    • 8. How much current do we need?
      • Power = Voltage * Current = V * I
      • I = 120 / 12 = 10 A
    • 9. How much energy do we need?
      • In 1 day:
      • Energy/day = 10 A * 24h = 240 Ah
      • Energy/day = 12 V * 240 Ah = 2880 Wh
      • In 5 days:
      • 5 * 240 Ah = 1200 Ah
    • 10. How much energy do we need?
      • Assuming:
      • Max discharge level: 50%
      • Battery capacity: 100 Ah
      • Total energy = 1200/ 0,5 = 2400 Ah
      • No of batteries: 2400/100 = 24
    • 11. How many solar panels are needed?
      • Assuming:
      • 4 sun peak hours/day (4000 W/m 2)
      • Panel current: 5 A
      • Energy needed/day: 240 Ah
      • Energy provided: 5 A * 4h = 20 Ah
      • No panels: 240/20 = 12
