Hypothetical Cost Savings Scenario
Let’s consider a hypothetical scenario. Suppose a homeowner wants to install a $20,000 solar panel system.
Scenario 1: Cash Purchase with Federal Tax Credit
Upfront cost: $20,000
Federal Tax Credit (30%): $6,000
Net Cost: $14,000
Scenario 2: Loan with 5% Interest over 10 years
Loan Amount: $20,000
Approximate Monthly Payment: $212 (principal and interest)
Total Cost over 10 years (including interest): Approximately $25,440
Scenario 3: PPA with a fixed rate of $0.10/kWh
Assuming average monthly electricity consumption of 700 kWh, annual savings could be around $840 (700 kWh/month * 12 months * $0.10/kWh). The total savings over 10 years could be $8400. However, the exact cost savings would depend on the specific terms of the PPA and the homeowner’s electricity usage.
This hypothetical example illustrates how different financing options can affect the total cost and the timing of payments. The best option depends on individual financial circumstances and preferences.
