The honest answer is: it depends on three things — how much electricity you use, how much sunlight your roof gets, and what your utility charges per kWh. But most homeowners who go solar see 60–90% of their grid electricity bill offset once the system is sized correctly.
The biggest lever is system sizing. An undersized system leaves savings on the table; an oversized one costs more upfront than it needs to. That's why we start every quote with a load analysis based on your actual usage, not a generic package.
Payback period is the other number people ask about. Most residential systems pay for themselves in 5 to 8 years, and continue generating savings for another 15–20 years after that. Battery storage adds resilience during outages but extends payback slightly, since it adds to the upfront cost.
