Simulation before steel
We model the array in simulation software using Karachi's irradiation data and the shading objects captured during the survey. That produces month-by-month expected generation — the number your ROI should be built on, not an optimistic rule of thumb.
String layout, inverter MPPT allocation and cable sizing all fall out of this model. If two panels will sit in a water-tank shadow every winter afternoon, we know before installation and re-plan the string.
An honest BOQ
Our bill of quantities lists panel make and wattage, inverter model, battery chemistry and capacity, structure specification and gauge, cable sizes, protection devices and earthing. Anything vague on a quotation is where corners get cut later.
ROI you can argue with
We show payback based on your actual bills, current tariffs and the simulated generation — with the assumptions written down so you can challenge them. A design you understand is a design you will not regret.
Key takeaways
- Simulated generation using Karachi irradiation data
- Brand- and model-level BOQ, no vague line items
- ROI derived from your real K-Electric bills
