Solar can reduce the amount of electricity a home purchases from the utility, but the financial effect depends on household usage, roof production, utility rules, remaining charges and the solar agreement or purchase cost. A high bill is a reason to investigate, not proof of a guaranteed outcome.
Start with kilowatt-hours
Dollar amounts can rise because of rates, fees, seasonal use or both. Review twelve months of electricity usage to understand the household pattern before sizing a system.
Efficiency can change the picture
Air sealing, insulation, HVAC performance, water heating, pool equipment and appliances can influence use. Planned electric vehicles or electrification can increase future demand. A solar plan should consider likely changes.
Compare the combined cost
For provider-owned solar, consider both the solar payment and remaining utility bill. For a purchase, include financing, maintenance and ownership costs. Avoid treating an illustrative utility forecast as a guarantee.
What to confirm before you move forward
- ✓Collect twelve months of usage
