The tool we wanted

WattGro began inside Power & Sun, where our engineers designed hundreds of systems a year for customers from Dubai to Lagos and were still redoing each one across half a dozen tools, from the first call to the handover, every time something changed. We built the tool we wanted: one place where the lead, the survey, the design, the price, the proposal and the delivery are the same record, where a design with a failing check cannot be submitted, where every issued proposal keeps a fixed copy of the design that later edits cannot change, and where the job does not stop at the signature but runs on through procurement, installation, commissioning and handover.

The calculation engine is built on established engineering methods — the standard models for sunlight on tilted planes, cold-morning and hot-afternoon voltage checks for every string, IEC 62548 and NEC 690.8 current limits, row spacing that avoids shading — and its yield results are checked against published figures for markets from Dubai to London. AI reads your documents, drafts proposal text and gives a second opinion on a design; it never produces a number your customer sees.
