Solar Panel & Inverter Calculator
Solar Panel & Inverter Calculator — quick estimate
Find how many panels, what inverter rating and how much roof area a given solar capacity needs — plus the annual generation. Adjust the inputs, then get an engineered solar quote from our team.
Your system
Uses modern bifacial module ratings and ~1,500 units/kW/year for most of India. Final design depends on shadow analysis, string layout and DISCOM sanction.

Thanks! Our solar team will send your tailored array & inverter design within one business day.
Indicative estimates only — not a binding quotation. Actual panel count, inverter and yield depend on the module, roof geometry, shading, tilt and DISCOM policy.
Need an exact BOQ, rate analysis or measurement sheet?
This is a quick engineering estimate. For tendering, billing or audit, our QS & estimation team prepares an item-wise BOQ, rate analysis and a verified measurement sheet to IS / CPWD norms — backed by 15+ years and ISO 9001:2015 quality processes.
