New Home Battery Calculator: See How Much You’ll Save

What is a Home Battery Calculator?

How Does It Work?

  1. Energy Consumption: Your average daily or monthly electricity usage.
  2. Solar Panel System: The size and output of your solar panel system.
  3. Electricity Rates: The cost of electricity from your utility, including peak and off-peak rates.
  4. Battery Specifications: The type and capacity of the battery you’re considering.
  5. Government Incentives: Any available rebates or incentives that can reduce the initial cost.

Steps to Use the Home Battery Calculator

  1. Enter Energy Consumption Data:
    • Input your average daily or monthly electricity usage. This information is typically available on your electricity bill.
  2. Enter Solar Panel Details:
    • Provide details about your solar panel system, such as its capacity (in kW) and average daily production (in kWh).
  3. Enter Electricity Rates:
    • Input your local electricity rates, including both peak and off-peak prices. This information can be found on your utility bill or provider’s website.
  4. Select Battery Specifications:
    • Choose the battery system you’re considering, including its capacity (in kWh) and efficiency.
  5. Apply Government Incentives:
    • If there are any government rebates or incentives available, enter these details to get a more accurate estimate.

Example Calculation

Scenario

  • Energy Consumption: 30 kWh per day
  • Solar Panel System: 6 kW system producing 25 kWh per day
  • Electricity Rates: $0.30 per kWh during peak hours, $0.15 per kWh during off-peak hours
  • Battery System: 10 kWh capacity with 90% efficiency
  • Government Incentives: $2,000 rebate

Calculation Steps

  1. Daily Solar Production Used Directly Without Battery:
    • 25 kWh * 40% = 10 kWh
  2. Daily Solar Production Exported to Grid Without Battery:
    • 25 kWh – 10 kWh = 15 kWh
  3. Daily Solar Production Used Directly With Battery:
    • 25 kWh * 80% = 20 kWh
  4. Daily Solar Production Exported to Grid With Battery:
    • 25 kWh – 20 kWh = 5 kWh
  5. Daily Energy Used From Grid Without Battery:
    • 30 kWh – 10 kWh = 20 kWh
  6. Daily Energy Used From Grid With Battery:
    • 30 kWh – 20 kWh = 10 kWh
  7. Cost Without Battery:
    • 20 kWh * $0.30 = $6 per day
  8. Cost With Battery:
    • 10 kWh * $0.30 = $3 per day
  9. Daily Savings:
    • $6 – $3 = $3
  10. Annual Savings:
    • $3 * 365 = $1,095
  11. Initial Battery Cost:
    • $10,000
  12. Cost After Rebate:
    • $10,000 – $2,000 = $8,000
  13. Payback Period:
    • $8,000 / $1,095 ≈ 7.3 years

Interpretation
