Calculator, commercial solar ROI
Commercial Solar ROI Calculator
Estimate an indicative payback range for a commercial solar installation, based on annual electricity spend and available roof or ground-mount space.
Assumptions
Indicative install cost $900–$1,300/kW · generation ≈1,450 kWh/kW/yr · daytime offset share ≈65% of generation · blended commercial rate ≈22c/kWh, capped at 70–90% of your current bill. Actual figures depend on load profile, roof/ground condition and grid connection requirements.
Indicative commercial solar ROI
- Indicative system cost
- $90,000 – $130,000
- Indicative annual savings
- $17,908 – $25,448/yr
- Simple payback range
- 3.5 – 7.3 yrs
Indicative only, subject to bill review and site assessment.
02Methodology
How we estimate commercial payback.
We apply indicative per-kW install cost and generation figures to your system size, value the daytime-offset portion at a blended commercial rate capped against your bill, then compute a simple payback range. A full proposal models your actual load profile and site constraints.
