You own the plant
You fund it, you own the asset, and every rupee it saves stays with you.
- Depreciation
- Accelerated depreciation at 40% WDV in year one. On a typical corporate tax rate that is roughly 10–12% of project cost back as a year-one tax saving — confirm your own position with your CA.
- Savings
- You keep 100% of the generation. Nothing is shared with a developer.
- Payback
- Typically 3–6 years for C&I rooftop at a healthy tariff. Yours depends on your blended tariff, region and roof — the calculator gives your number, not an average.
- Asset
- A 25-year asset on your balance sheet, with the loan (if any) usually clear inside 5–7.
Trade-off: You fund the capital and carry the O&M.
