Please note: this is an estimate, not a quote. Actual output and savings depend on the sunlight at your site, shading, roof direction and grid availability. Subsidy amounts follow PM Surya Ghar Muft Bijli Yojana and state government schemes for residential consumers as of October 2026; state schemes may be budget-limited. CO₂ figures use the Central Electricity Authority's grid emission factor of 0.727 kg CO₂ per kWh (CO₂ Baseline Database v20) and 625 kg CO₂ absorbed per tree.
