How the Numbers Typically Work
ROI is built on your actual tariffs and consumption profile. The illustration below shows the order of magnitude for well-suited commercial and industrial rooftops.
| System Size | Annual Units* | Annual Savings @8 | Indicative Paybacк | Indicative IRR |
|---|---|---|---|---|
| 100 kW | ~1.48 lakh units | ~11.8 lakh | ~3.5 years | ~27% |
| 250 kW | ~3.70 lakh units | ~29.6 lakh | ~3.3 years | ~28% |
Values are illustrative, using a reference energy value of ₹8/kWh and good solar resource. Actual performance depends on location, design, maintenance and tariff changes.
