For EPCs and installers

Run every job from the first lead to the final handover, with the engineering done properly.

You win work on speed and keep it on delivery. WattGro gives a five-person team what a fifty-person team has: a pipeline that keeps every lead followed up, a survey tool that draws the roof to scale, a design engine that checks every string at cold and hot extremes, a bill of quantities priced from a live catalogue, a proposal on your letterhead reviewed by a second engineer — and, once it is signed, one place to buy, build, commission, invoice and hand over the job.

  • Win: leads from the estimator, your website or the API; a deals pipeline with weighted forecast; follow-ups, a shared calendar and email from templates
  • Survey: roofs, ground arrays and carports on the map, obstructions included; weather from PVGIS, NREL, NASA POWER or Solcast
  • Design: on-grid, hybrid, off-grid and PV-diesel; string and MPPT allocation; cable and protection sizing; hour-by-hour simulation with loss waterfall and P50–P99
  • Price: BoQ with country tax rules; payback, IRR, NPV, LCOE; IPP and PPA models
  • Issue: techno-commercial offer, customer proposal, project report and slides, shared by link
  • Deliver: programme and milestones, purchase orders and goods received, task board, Gantt and timesheets, snag list, commissioning checks, customer invoices and handover
  • Look after: asset and warranty register, planned service visits, tickets and real output against the forecast

What it is not

WattGro is project software, not an engineer. Every number is an engineering estimate until a qualified engineer has surveyed the site and signed the design. The public estimator never prices a system.

How we build

Every product here is built multi-country from the first line: your currency, your tax rules, your language. Every product starts free, with no card. Built in Dubai by L K Verma and a small team, for people and businesses whose lives run across borders.
