The intelligent combination of modern solar energy and industrial storage technology secures the future of our energy supply. Together with Faber Solartechnik, we at Faber E-Tec have successfully connected a pioneering infrastructure project to the grid in Ostwestfalen-Lippe. Right next to the large-scale photovoltaic system in the municipality of Rödinghausen, our highly developed Battery storage systems for solar farms for the highly efficient intermediate storage of green electricity. This future-proof co-location project demonstrates how we are technologically leading the regional energy transition and making it economically viable.
Why a battery storage system is essential for solar farms
What are the benefits of a highly efficient battery storage system for solar farms?
A modern Battery storage systems for solar farms enables the enormous generation peaks of large-scale photovoltaic systems to be flexibly stored intermediately and fed into the power grid at a later time when demand is high. This prevents local grid overloads, avoids unprofitable forced curtailment and sustainably maximises the economic return of the entire solar installation through strategic power trading on the spot market.
The open-space solar plant in the Rödinghausen district of Bruchmühlen has a remarkable installed peak output of around 3.21 MWp. With more than 4,500 solar panels, the extensive solar field generates a projected annual yield of around 3.39 gigawatt-hours of clean energy. This amount is theoretically sufficient to reliably supply well over 1,000 average households with green electricity all year round. A clean initiative that significantly drives local climate protection in cooperation with the municipality.
However, during periods of prolonged strong sunlight, this high generation output regularly leads to massive peaks in the regional distribution network. Without a high-performance buffer solution, costly curtailments by the responsible network operator threaten at such moments. This is precisely where we demonstrate the enormous technological added value that a future-proof battery storage system for solar parks offers for the long-term grid stability and economic viability of green electricity projects.
Technical excellence
Our PowerCube series in demanding outdoor use
For the demanding project in the Herford district, we opted for a perfectly coordinated system configuration. Our factory-preconfigured outdoor storage systems from the tried-and-tested PowerCube series are being used. Specifically, we have installed the PowerCube 836 on site with a gross capacity of 836 kWh, as well as the flexibly scalable 418 kWh model.
The technical parameters of this entire system are setting new standards in the German B2B sector:
- Safe lithium iron phosphate technology (LFP): This modern cell chemistry offers maximum inherent safety, as thermal runaway is ruled out by design and it operates completely free of critical raw materials such as cobalt.
- Outstanding durability: We guarantee a service life of at least 10,000 full cycles for our battery modules with a remaining residual capacity of 80 per cent.
Integrated liquid cooling: Intelligent thermal management ensures even heat dissipation and permanently keeps all battery cells in the optimum temperature range, even during intensive charging and discharging processes.
Even extreme local climatic conditions present no obstacle for our systems. Thanks to the robust construction with a high IP55 protection rating, the entire system operates completely trouble-free across a temperature range from an arctic -40 °C to a summery +60 °C. A multi-stage safety concept, including automatic aerosol fire suppression and integrated explosion protection, safeguards the investment round the clock. This makes our system the first choice for companies looking to buy a durable battery storage system for solar parks.
Transformer compact station - Fast delivery!
Turnkey EPC complete solutions from a single source by Faber E-Tec
For large-scale projects of this size, the mere delivery of storage components is by no means sufficient. As an end-to-end EPC contractor (Engineering, Procurement, Construction), we undertook the entire electrical planning, logistics, and final implementation for the project in Rödinghausen. In doing so, we minimise technical interface risks for our B2B clients and guarantee maximum schedule reliability.
A particular advantage of our working method is the ex-works pre-configuration. The entire large-scale energy storage system is delivered by lorry as a tested complete system. As can be seen in our current project video, a mobile crane lifts the compact container modules, weighing around 8 tonnes, directly onto the previously poured foundation plinths. From the initial feasibility analysis to the construction of the matching, in-house compact transformer substations and the turnkey handover, typically only 10 to 14 weeks elapse.
Compliance with all stringent regulatory requirements for the German power grid is also ensured right out of the box. A battery energy storage system for solar parks installed by us features all necessary certifications according to the VDE-AR-N 4110:2023 grid codes for connection to the medium-voltage level. Thanks to advanced smart grid functions such as volt-var, freq-watt, and precise ramp rate control, smooth and rapid commissioning by the grid operator is guaranteed.
Strategic electricity trading for maximum B2B return
Following its successful installation, the ground-mounted PV system in Bruchmühlen is now ready for highly profitable, time-shifted electricity trading. Instead of feeding the valuable green electricity into the grid unused during periods of negative prices, the energy is stored with minimal losses during the sunny midday hours. The integrated inverters offer a rated AC output of 418 kW and operate with an excellent system efficiency of 95 per cent.
Via an intelligent, algorithm-based connection to the spot market, electricity is sold precisely when exchange power prices are at their highest. This automated arbitrage measurement converts volatile feed-in tariffs into predictable, maximised revenues. As a result, a modern battery storage system for solar parks from Faber E-Tec pays for itself within a very short space of time.
A future-proof model for municipalities and city administrations
The successful project in Rödinghausen also shows how important close cooperation with local authorities and the town administration is. For local residents, the visible expansion of the solar park represents a clear signal for regional climate action. The municipality is leading by example here and securing a sustainable energy supply right on its own doorstep.
At the same time, investors and companies benefit from tremendous certainty in planning. The combination of regional value creation, proven engineering from Faber E-Tec and close coordination with the administration makes this project a true flagship model for the whole of North Rhine-Westphalia. Anyone wishing to make a sound financial investment in renewable energy today can no longer afford to ignore professional storage integration.
