Enter your system size and installed cost per watt, plus any tax credit, rebate, or incentive percentage you qualify for — incentive rates change and vary by location, so enter your own current figure rather than trusting a hardcoded default.
Estimate only — confirm current incentive eligibility with a tax professional or installer.
Gross cost is system size in watts multiplied by your installed cost per watt. We then apply your incentive percentage as a straight discount to estimate net cost. Since incentive programs and rates change by year, location, and utility, this field is left for you to fill in rather than assumed — check current federal, state, and local programs before relying on a specific number.
US residential solar typically runs $2.50-$3.50 per watt installed before incentives, so a 6 kW system lands around $15,000-$21,000 gross. Local permitting, roof type, and equipment choice all shift this.
Check current federal, state, and utility program rates for your location and year — they change, so this calculator doesn't assume a figure for you. A tax professional or local installer can confirm what you currently qualify for.
