Challenges and solutions
Aligning with the DSO
Documentation and schedules had to match operator requirements.
Nivato solution
We maintained continuous communication with the DSO and secured approvals before construction began.
Component selection for local conditions
The PV plant needed to perform reliably despite weather variability.
Nivato solution
We chose high-efficiency modules and durable structures, mapping installation stages to avoid delays.
Synchronising prefab and on-site works
Electrical prefabs had to be ready as field works progressed.
Nivato solution
Modular prefabrication and controlled deliveries shortened installation time on site.
