Estimate panels needed to offset your electricity usage.
This is a simplified estimate. A professional solar installer will perform a shade analysis, roof orientation assessment, and detailed energy audit. South-facing roofs at 15–40° pitch maximize production. East/west-facing panels produce 15–20% less.
The federal solar tax credit (ITC) currently allows you to deduct 30% of installation costs from federal taxes. Many states offer additional incentives. Get 3 quotes from certified installers (NABCEP certified) before committing.
