• The transportation of the equipment to the location of the plant is a very important point, especially for PV modules because they are very fragile and can be exposed to internal cell breakages.
  • Deformation of the land/roof in which the plant will be installed can lead to fatal damages, that’s why adequate floor/roof load studies must be carried out.
  • Special attention should be paid to the installation of the modules because wrong installation of the modules or the mounting structures can cause breakage, or wrong orientation of the PV modules.
  • Inappropriate commissioning of the inverters can drive to a wrong set up of inverter parameters with subsequent losses.
  • Cables should not be forgotten. Tight or loose cables can lead to under-performance or hot spots in junctions, as well as cables exposed to UV sun irradiation, which will cause them damage.
  • No existing grounding system, wrong material combination or not proper installation, will expose plant’s equipment to electrical defects or lightning strikes, which can seriously damage the installation.

After the plant’s completion, as-built files must be delivered to the owner to allow safe maintenance of the plant during the long period corresponding to the operation of the plant.
