The simple answer
A 3 kW rooftop system is a common starting point for Indian households, but the right capacity depends on monthly units—not only the rupee value printed on a bill.
Generation changes with location, roof orientation, shadow, equipment and season. A practical estimate should separate electricity used directly in the home from electricity exported to the grid.
What matters in practice
SolarSol’s calculator models those assumptions and keeps residential subsidy estimates separate. Government subsidy is not included for commercial or other non-residential customers. A technical site survey is still required before finalising capacity, structure and pricing.
- Use recent electricity consumption, not a single unusually high or low bill.
- Keep modeled savings separate from subsidy eligibility.
- Confirm roof, shadow and sanctioned-load conditions through a site survey.
Your next step
Use SolarSol's calculator for an initial estimate, then request a transparent preliminary quotation. Nothing is final until technical feasibility and component availability are confirmed.
