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.

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.

Repairs should be performed exclusively by authorised personnel.

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

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