More than solar panels. Integrated systems, engineered for performance.
Design, installation, and long-term maintenance of rooftop and ground-mount solar plus battery storage for Romanian industrial and commercial sites: one contractor, one guarantee, backed by international engineering since 1994.
We're the contractor who stays after commissioning.
Most solar installers in Romania sell equipment and move on. Hiieko Romania designs, builds, and maintains every system under one contract, with a workmanship guarantee and a maintenance plan that starts the day the system goes live.
Site assessment & sizing
We size the system to your real consumption and structure, not a generic package.
Installation & commissioning
Our own crews, not subcontracted labor, installed to ANRE grid-connection requirements.
Workmanship guarantee
A minimum 60-month workmanship guarantee on every installation we complete.
Ongoing maintenance
Scheduled service and monitoring for the same 60-month period after handover. The system stays our responsibility.
Four systems. One team.
For industrial platforms, logistics halls, production facilities, and unused land.
Rooftop Solar
Photovoltaic systems on industrial and commercial buildings, sized for self-consumption.
Ground-Mount Solar Parks
Ground-mount projects on unproductive land, from feasibility study to grid connection.
Battery Storage (BESS)
Industrial battery systems for peak shaving, backup power, and stored-energy value.
EV Charging Infrastructure
Charging infrastructure added to your solar and battery system, for fleet vehicles or facility use, powered by what you already generate.
Energy prices keep climbing. These businesses stopped caring.
Over 200 MWp installed across Romania's highest-consumption industries: proof the energy crisis doesn't have to be permanent for yours.

Hiieko Romania SRL is part of Hiieko Group, which has designed, installed, and maintained construction technical systems since 1994. In Romania, that same engineering discipline was applied to a purpose-built subsidiary, established in 2020 specifically to develop industrial solar parks and storage facilities.
We're not a panel installer that appeared last year. We're part of a group with three decades of execution on complex sites and a Romanian team that stays accountable after handover.
