Installation
From civil groundwork to final grid synchronisation — Eturn delivers complete PV installations under a single fixed-price contract, with no subcontractor coordination risk for the client.
One contract, zero coordination risk
Eturn installs PV systems as a full EPC contractor — meaning civil works, structural mounting, electrical installation, and grid connection are all delivered under one contract, by one team, with one point of accountability.
We work on residential rooftops, commercial and industrial buildings, agricultural structures, carport canopies, and open-field solar parks. Our installation teams are active across the Netherlands, Belgium and Germany.
Every phase of installation, in-house
From the first groundwork to the final commissioning test — our crews handle the full scope without reliance on external subcontractors.
Civil & Structural Works
Ground anchor installation, penetration sealing, structural reinforcement, and substructure works completed to structural engineer sign-off before any module is touched.
Mounting System Installation
Aluminium racking, ballasted flat-roof systems, east-west configurations, and ground-mount pile-driven structures — installed to the manufacturer's certified specifications.
DC & AC Electrical Installation
String cabling, combiner box wiring, inverter installation, protection devices, and distribution board connections — all tested to IEC and national standards.
Grid Connection
Meter cabinet upgrades, grid protection relay installation, DSO notification, and export limitation configuration managed end-to-end by our grid specialists.
Commissioning & Testing
Full IV-curve testing, insulation resistance checks, earthing continuity verification, and production validation before we hand over the keys.
Documentation & Handover
As-built drawings, test records, component serial logs, warranty certificates, and grid connection confirmation — delivered as a complete handover package.
From mobilisation to handover
A structured installation programme with clear milestones gives clients full visibility and keeps projects on schedule from day one.
Mobilisation Planning
We confirm crew allocation, equipment hire, delivery scheduling, and access arrangements — producing a detailed programme before work begins.
Civil & Structural Works
Foundation, anchoring, or ballasted substructure installation, completed with structural sign-off before any module or inverter is placed.
Module & Inverter Installation
Racking assembly, module mounting, string wiring, inverter installation, and protection device fitting — carried out by certified Eturn installation crews.
Electrical & Grid Connection
AC cabling, board connections, meter cabinet work, and grid connection notification coordinated directly with the local DSO.
Commissioning & Handover
Full electrical testing, system commissioning, monitoring platform activation, and formal handover with complete as-built documentation.
What a single-contractor installation means for you
One point of contact
With Eturn as your sole EPC contractor, there are no gaps between subcontractors to fall through. We own every phase from groundwork to grid connection.
On time, every time
Integrated procurement and installation scheduling means materials arrive when crews do. Our 98% on-time completion rate is a direct result of this coordination.
Factory-trained crews
Our installation teams are trained and certified by the manufacturers whose equipment they install — ensuring every system is built to the specification that warranties depend on.
Fixed price, no surprises
A fixed-price EPC contract locks in your total project cost from the moment we sign. Scope changes are handled transparently — never added to the final invoice as surprises.
