Repairs should be performed exclusively by authorised personnel.

If an unintended plant outage occurs, local electricians can be hired, even if they are not familiar with PV systems and have not received PV-specific training.

A stock of spare parts on-site should be avoided because it ‘ties up’ capital.

Access to spare parts is crucial during the entire operation period of a large PV system.

If technical failures occur, for example, during a monsoon, it is not a problem to delay carrying out repairs until the end of the rainy season.
