PV and ventilation installation as a subcontractor: what we take on
Mounting structures, modules, the DC side and inverters – and for ventilation, from the duct network to the rooftop air handling unit. An overview of our installation services.
Alongside fibre civil works, we carry out installations for solar installers, building services firms and general contractors. We work to your plans and agree the scope clearly in advance.
PV installation
- Mounting structures and rails on industrial, flat, green and metal roofs
- Module installation to the layout plan, every module documented
- DC cabling to the string plan and measurement
- Inverter installation
The AC connection and grid operator registration are done by a registered electrical contractor – usually your company. That keeps responsibilities clearly divided.
Ventilation installation
- Rectangular and circular ducts with fittings
- Hangers and fixings as specified
- Installation of air handling units and rooftop ventilation plant
- Residential ventilation with heat recovery
Billing and process
We bill installations by measurement, per kWp or at a fixed price per building. Before starting we settle material, scaffolding and lifting; on site, our German-speaking foreman is your contact.
