The fine print

What this compares. Your current average power bill of $213 a month against your solar payment of $183.25 a month, over 25 years. Utility escalated at 13.5% per year, solar at 2.99% per year.
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.
Ameren Illinois rates are moving. Ameren Illinois residential rates have risen about 94% since 2021, from roughly 8 cents to 15.5 cents per kWh in 2026, driven by ICC approved increases and a sharp rise in regional capacity prices. Past increases do not guarantee future ones.
This is an estimate, not a contract. Production, rates and savings are projections. Nothing here is a guarantee.
