Energy infrastructure & storage solutions
Substation
The grid connection is the bottleneck. At our company, it is located right on our own premises.
The compact substation determines the commissioning date – and is often the component with the longest delivery times. Unless you manufacture it yourself. That is precisely what we do in our own plant in Bünde (North Rhine-Westphalia) – fully compliant with technical connection conditions (TAB).
BESS
Industrial battery storage. Perfectly integrated into your PV project
A photovoltaic system only realises its full economic potential when combined with smart storage. As an EPC partner, we design, size and seamlessly integrate industrial battery energy storage systems into your commercial rooftop system or solar park.
Rooftop
commercial rooftop photovoltaics
Turn unused industrial and commercial roofs into lucrative power plants. As an experienced EPC partner, we realise turnkey rooftop solar systems, precisely dimensioned for maximum self-consumption or intelligent surplus feed-in. In this way, you make your business independent of rising energy prices and improve your carbon footprint.
Open land
Solar parks and ground-mounted PV systems
From the initial feasibility study to certified grid integration, we construct large-scale ground-mounted systems for investors and municipalities. Using highly efficient modules, robust medium-voltage technology and custom-fit compact transformer substations, we guarantee maximum system availability for full feed-in under the EEG or lucrative PPA models.
Commercial rooftop solar PV
Commercial photovoltaics for warehouse, flat and industrial roofs from 5,000 m² – structurally tested, including roof renovation if required.
ground-mounted solar parks
Ground-mounted photovoltaic system from site assessment and permitting to the multi-megawatt solar park.
EPC main contractor
As an EPC photovoltaic general contractor, we undertake engineering, procurement and construction under a single contract.
Battery storage
PowerCube and PowerBlock from 418kWh to 5MWh, against curtailment and negative pricing hours, in new builds as well as in retrofits.
Mains connection
Medium-voltage grid connection for PV including compact substations and transfer station from our own production.
Operation and Service
Technical management, monitoring, maintenance and fault rectification – with our own engineers instead of chains of subcontractors.
Frequently asked questions
Questions and answers about our solar solutions
From what size does Faber Solartechnik install photovoltaic systems?
We design and build turnkey Commercial and utility-scale solar PV systems from around 5,000 m² total area.
- Commercial rooftop systems: Equates to about 500 kWp and above.
- Ground-mounted solar farms: The economically viable entry point is significantly higher (starting from approx. 5 hectares).
The technical expenditure for grid connection, medium-voltage engineering and general planning is incurred regardless of the size of the system and only becomes worthwhile from a certain output. For smaller projects, we are happy to pass you on.
What services does Faber Solartechnik provide as an EPC partner?
As an experienced EPC main contractor (Engineering, Procurement, Construction) we realise your large-scale photovoltaic project completely from a single source. Our range of services includes:
- grid connection, construction, landscape, layout and string planning
- Design of medium-voltage and protection systems
- Procurement of all components (modules, mounting structure, inverters)
- Turnkey assembly as well as commissioning and complete documentation
Your advantage: you receive exactly one contract, a single point of contact and a turnkey system, instead of having to coordinate countless individual trades yourself.
Are the grid connection and transformer station covered for large-scale PV projects?
Yes, and this is our key unique selling proposition (USP). The compact substations and transfer stations for the medium-voltage connection we manufacture ourselves within the corporate group:
- In-house production: The certified concrete components are manufactured in the factory in Bünde (East Westphalia) cast and equipped with electrical engineering.
- Everything from a single source: Protection concept, system certification and direct coordination with the distribution network operator are handled via the same part of the building.
Result: Interface issues between the PV installer and the substation supplier as well as typical delivery time and warranty risks are completely eliminated.
Does Faber Solartechnik realise photovoltaic projects throughout Germany?
Yes. Our corporate headquarters and production plant are located in Bünde (North Rhine-Westphalia), additionally, technology and sales are Dresden represented.
- From these two locations, we implement commercial rooftop systems and solar parks in the entire federal territory (throughout Germany) with our own installation teams.
- In complex grid connection planning, we work seamlessly with all relevant German distribution system operators.
Can battery energy storage systems (BESS) be integrated into the solar power system?
Yes. Industrial battery energy storage systems (BESS) can be seamlessly integrated into both new installations and existing systems. Typical use cases for companies and investors are:
- Increase in self-consumption
- Peak shaving
- Grid-friendly and flexible operation
Advantage with Faber: Because the design, AC connection and medium-voltage technology are planned across all trades, no subsequent external system is created, but rather a perfectly calculated overall energy concept.
Which areas are suitable for a solar park or a commercial roof?
- For ground-mounted solar parks: Of particular interest are conversion areas, verges along motorways and railway lines, disadvantaged areas and arable land with low soil quality – ideally from approx. 5 hectares with a grid connection point within reach.
- For commercial rooftop systems: Surface areas are the decisive factor from approx. 5,000 m², the roof structural analysis, the remaining lifespan of the roof membrane, and the orientation.
