How to Use the Solar Lease Calculator (Step by Step)

Using the calculator is straightforward. Here’s how it works:

Step 1: Enter Solar System Information

• System Size (kW): The capacity of the solar system (commonly 5kW–10kW for homes).
• System Cost: The estimated cost of the solar installation.
• Lease Term: The number of years you plan to lease the panels (usually 15–25 years).

Step 2: Add Financial Details

• Monthly Lease Payment: The fixed payment charged by the solar company.
• Annual Escalation Rate (%): Some leases increase payments slightly each year.
• Electricity Rate ($/kWh): Your current utility electricity rate.
• Annual Utility Bill: The amount you currently spend on electricity.

Step 3: Add Energy Production Data

• Expected Energy Output (kWh/year): Estimated yearly generation from the solar system.
• Utility Rate Growth (%): Anticipated yearly increase in utility electricity prices.

Step 4: Calculate

Click “Calculate” to instantly see:

• Monthly lease payment.
• Total lease cost over the term.
• Estimated total savings compared to staying on grid power.

Practical Example

Let’s imagine you’re considering a 6kW solar system for your home.

• System Cost (if purchased): $18,000
• Lease Term: 20 years
• Monthly Lease Payment: $120
• Annual Escalation Rate: 2%
• Current Utility Bill: $180/month ($2,160/year)
• Utility Rate Growth: 3% annually
• System Energy Output: 8,500 kWh/year

After running the Solar Lease Calculator:

• Total Lease Cost (20 years): ~$33,000
• Total Utility Cost (20 years without solar): ~$53,000
• Estimated Savings: ~$20,000 over 20 years

This shows that leasing solar panels could save you thousands of dollars while also helping the environment.

2. How does the Solar Lease Calculator work?

It compares your lease payments against utility bills to estimate savings and long-term benefits.

3. Is leasing solar cheaper than buying?

Leasing has lower upfront costs, but buying usually provides greater long-term savings.
