Engi­nee­ring & Con­struc­tion Services

The design and con­struc­tion phase sets the foun­da­ti­on for the per­for­mance and the tech­ni­cal avai­la­bi­li­ty of your PV-plant. Due to our expe­ri­ence in O&M, green­tech can advice you to achieve the best possible plant design and avoid mistakes in the early stages of your project with the aim of high per­for­mance, low failure rates and reduced main­ten­an­ce costs.
