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.
