And let us tell you: Inspect it, even if there is no visible damage! The electrical data (current-voltage-curve) needs to be verified, and a technician should check to see if the lightning protection is still intact. A visual inspection of the installation is important to get an impression of what the current state of affairs is.
Winds and ice are strong
Strong winds or ice during the winter can have damaged or moved the generator, and an on-site inspection can easily reveal that. It is also important that the installation’s reference sensor is accessible and clean. Bolts and plugs need to be checked.
Screws should be tight, also plugs – did water get into them? During the inspection, there should be at least a random check if the panels’ junction boxes are undamaged.
Look whether the installation is dirty or not
As part of such an inspection, a single glance will show if the installation is dirty or not. If and how much any dirt diminishes the solar electricity yield, can easily be seen from the electrical data. Based on that, the technician and the customer can jointly decide if cleaning is necessary. (HS)
