Design Your Solar System
Two ways in: enter your bill, or build your exact appliance load. Get a full engineered design — system size, panel count, inverter, battery, roof area, cost, payback and a downloadable PDF report. Optionally upload your bill and we'll read it automatically.
We engineer the optimal kit for your requirement — the panel, inverter and battery below update automatically as you change your bill, city and system type. Tier badges show the product grade.
Pick exact models from our stock, or leave “Auto” to let us choose that item. Fine-tune raw numbers (panel count, inverter kW, roof area) in Engineer Mode below.
Estimates Backed by Real Plant Data
This calculator is tuned against telemetry from our own 9.5 MW installed fleet — not brochure figures.
Fleet-Calibrated
Performance ratios validated against live generation data from 8 operating plants across Karachi and Lahore.
PVsyst-Verified
Every formal proposal includes an hour-by-hour PVsyst simulation with shading analysis — the estimate you see here is the conservative floor.
Bankable Output
Our projections are formatted for CFOs and lenders: IRR, NPV, DSCR-ready cash-flow tables on request.
