Due to the dry summer months and the low rainfall, sometimes in the fall, it is sometimes necessary to supply the pond system with water in circulation, for this the use of pumps and pond aerators is essential - which, however, require energy.
Initially, this was generated by units that were only needed for a short time, but when an increasingly long-lasting cycle operation was necessary, another solution had to be found.
So it happened that the first efforts in 2013 to electrify the system using photovoltaic modules were undertaken to ensure regenerative cycle operation.
In 2014, a revised project planning provided for an open area elevation with 20 kWhp output and its own operating building to house and maintain the technology. Various regional companies took part in the tender.
Financing could also be drawn up by the end of 2014. Only the approval process dragged on until spring 2016. After further official hurdles, the construction work began with the civil engineering work and foundation laying from August 2016. The system is currently being expanded and since July 2017 the PV system has been supplying the pond system with energy. After the automation is complete, the system is controlled by a PLC for optimal use of the generated energy.
