What Solar Savings Look Like in Pontiac

The prevalence of single-family homes (64.6%) and older housing stock (median age ~1965, 58.3% pre-1980) suggests many roofs may be suitable for solar, though condition assessments are important. Pontiac's small-town character implies consistent lot sizes, which can simplify system design and installation.

How We Calculate Your Savings

This calculator uses your custom utility rate (default $0.16/kWh for Illinois) with a 4.5% annual escalator compared to our fixed lease rate as low as $0.10/kWh plus battery backup for 15 years. A low-escalator option is also available for a lower starting payment. After the 15-year lease, you can keep the system for a low fair-market buyout — then your electricity cost drops to near-zero for the remaining life of the panels (25+ years). Your actual savings may vary based on your specific usage patterns and system size.
