Measures to prevent vandalism and theft need to be implemented - during the construction phase of the project as well as during the operation period.

Measures also need to be taken against unauthorised access to the site (during construction and operation) for safety reasons (to prevent injury and death).

A 5 MW PV system could have as many as 20,000 PV modules.

A perimeter fence around a PV plant will cause unacceptable delays when maintenance personnel needs access.
