Mustakbal Clean Tech engineers, procures and builds solar PV and battery storage infrastructure across the Middle East and Africa. After 25 years and more than 400 projects, they lead the category. Their brand didn't show it though, and the old site still looked like a generic solar installer. We rebuilt the identity and the website to position them as the technology-led engineering firm they already are.

MCT builds hybrid solar plants with grid-forming battery storage and complex SCADA controls for clients like EDF, Veolia, Masdar and TotalEnergies. But the old site didn’t reflect that.
Mustakbal didn’t want their brand to look any other cleantech company with soft greens and leaves. They needed to look like a modern engineering company instead.
MCT’s customers are developers, governments and banks that commit to assets that run for decades. The identity had to feel exclusive but approachable, premium but not cold, technical but elegant.

A monochromatic base, one expressive accent, geometric order and a lot of space. Photography went dark and technical, so the infrastructure reads as engineering rather than landscape.
We designed everything from the pitch deck, the Office template, the email signature to the print work on the crew's safety vests and site jackets.
Buying infrastructure isn’t a quick decision, so we structured the site around buyers’ questions. The proof - the project record, the certifications and the safety standards - is where buyers look for it.
