Since 2019, SPP4F, under the management of Mr. Lars Ihle, has been serving our company as an EPC service provider. The focus of the collaboration was particularly on the construction of ground-mounted photovoltaic systems with a capacity range of 400 kWp to 8 MWp.
The services provided by SPP4F included:
Erection of the substructure according to specifications
Cable laying according to VDE
Laying of DC and AC cables
Construction of inverter sites according to plan
Construction of fence and gate systems according to specifications
Construction of concrete foundations if ramming was not possible
Construction of the station areas according to plan
Implementation of the earthing system according to specifications
Even with challenging projects, we could always rely on SPP4F's professional, reliable, and timely execution. The company particularly distinguished itself through its ability to respond flexibly to changes in the construction site while still ensuring a high level of execution quality.
Construction work generally proceeded very smoothly. The coordination effort during the construction phase was pleasingly minimal, which represents a decisive advantage for our project organization.
It should be noted that AC and medium voltage connection work has not been part of the services provided by SPP4F to date.
We greatly value the collaboration with Mr. Lars Ihle and his team and can fully recommend SPP4F as a competent, committed, and reliable partner in the field of open-space photovoltaics.
