How accurate is the ROI calculation?
Our calculations are based on 10 years of historical NASA irradiation data for your specific latitude and longitude. We account for typical system degradation, inverter efficiency, and rising grid electricity costs.
Are state and central subsidies supported?
Yes. Admins can include subsidy assumptions in quote pricing and customer-facing summaries.
What maintenance is required?
Most systems need periodic panel cleaning, annual electrical checks, and production monitoring.
