What you pay every month, for 25 years

Orange is Tri-County Electric Cooperative, climbing 7.5% a year. Green is your loan payment, which is fixed and never rises. Your payment starts higher than your current bill, and the power bill passes it in year 11. From there the gap is money you keep.

Where this lands

A loan is a fixed payment, so the early years cost more than staying with the utility. Your power bill passes your loan payment in year 11, and you come out ahead overall in year 18.

The fine print

What this compares. Your current average power bill of $214 a month against your solar loan payment over 25 years. The utility is escalated at 7.5% per year. The loan payment does not escalate, it is fixed at $305.87 for months 1 to 36 and $430.67 for months 37 to 300.
Your incentive is not included above. The proposal estimates $18,698 in Illinois SRECs. The payment schedule shown does not assume it has been applied to the loan. Applying it would reduce what you pay.
Still connected to the grid. You are still connected to the utility grid and would be expected to pay a small fixed monthly rate, considered the standard connection fee.
Where the numbers come from. System specs, production, offset, the the loan payment schedule and the 9.74% APR were all read from your Solo proposal on 2026-07-29. The 7.5% utility escalation is Rundle Solar's standard planning assumption, not a figure from the proposal.
This is an estimate, not a contract. Production, rates and savings are projections. Nothing here is a guarantee.
