EPC: Engineering Procurement Construction

ZEDEICH works with EPC contracts. This means that we are responsible for all the activities from design, procurement and construction, to commissioning and handover of the project to the End User or Owner. We complete the planning of all the technical details and buy or assemble the system components; from modules and mounting systems to converters.

When all needed parts are in store, the solar system is fully constructed by our team, until it’s ready to use (turnkey installation). Each step is accompanied by a comprehensive quality assurance and detailed documentation of the location, to ensure a safe technical operation.


Exploitation and Maintenance

High yields can only be achieved with an installation that is fully in operation. That's why ZEDEICH aims to let your installation work continuously and perform at the highest possible level.

From remote monitoring to quick response in case of potential errors; we offer you a full range of services that we all personally control and coordinate. Of course this also means detailed reporting.

Furthermore, with our "performance guarantee" you are assured of a minimum annual return for the entire duration of the contract.
