How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Usable Energy Needed = 10, Lead-Acid Cost = 150, Lithium Cost = 300, Lead-Acid Cycle Life = 500 = 6 input(s) provided
  2. Calculate Lead-Acid 10-Year TCO
    Lead-Acid 10-Year TCO
    24000 = $24,000
  3. Calculate Lithium 10-Year TCO
    Lithium 10-Year TCO
    3750 = $3,750
  4. Calculate Lead-Acid Initial Cost
    Lead-Acid Initial Cost
    3000 = $3,000
  5. Calculate Lithium Initial Cost
    Lithium Initial Cost
    3750 = $3,750
