Why Hiieko

International engineering, delivered locally.

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.

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. Meet the team behind the work
