DisclaimerApproximate estimate. Uses an average Indian grid emission factor of 0.82 kg CO₂ per unit and an average absorption of 21 kg CO₂ per tree per year — both widely-cited approximations, not site-specific measurements.
How the offset is estimated
- Annual generation = system size × generation per kW.
- CO₂ offset = annual generation × 0.82 kg CO₂ per unit (India's average grid emission factor).
- Trees equivalent = CO₂ offset ÷ 21 kg CO₂ absorbed per tree per year.
These are the same rough conversion factors used across most public solar calculators — useful for a sense of scale, not a certified carbon-accounting figure. For system sizing itself, try the Solar Size Calculator.
