About Us
Sōlrein is a solar performance company.
We exist for a simple reason: solar rarely delivers what it promises. Systems are sold without honest analysis. Panels lose output to dust and heat from the first week. Faults go unnoticed for months. The gap between what solar could produce and what it actually produces is wide — and almost no one is working on it.
That gap is our entire business.
Our story
Sōlrein began as Clean Solar, with one mission: keeping panels clean in one of the sunniest, and dustiest, places on earth.
We stepped away for a time. We came back with a wider view — that cleaning was only one piece of a larger problem, and that solving it properly meant working across the full life of a solar system: before the purchase, after the installation, and every day in between.
Clean Solar became Sōlrein. The mission became performance.

Sōlconsult
Sōlconsult is independent advisory for homeowners. Most solar decisions are made on a seller's numbers; we put honest analysis first — consumption, site, system options, real payback — so the decision is yours, made on evidence. The right system, bought well, outperforms the wrong one for twenty-five years.

Hossam M. Mounir
Hossam M. Mounir is a Mechatronics Engineer specializing in solar plant performance after installation, from dust accumulation to module overheating. He holds BSc and MSc degrees in Mechatronics Engineering from the German University in Cairo (GUC), where he is currently completing a PhD in the same field. He previously served as Business Development Manager at Solis Depot, a HUAWEI Smart PV Value Added Partner (VAP), and is Regional Business Development Manager at Maxima MEA, part of Asunim Group.
He founded Sōlrein to bring these two sides together — applying research on soiling and thermal losses to solutions that hold up in the field, not just in a study.
