The energy production of a PV power plant plays a significant role in the market evaluation of a project, as it is a key input into the financial models of the profitability of a solar project [1]. In this regard, the technical conditions of the PV array and of the PV modules have a great impact on the systems performance and the value of assets (assets’ performance).

To give plant operators or asset managers confidence that PV power plants perform at current standards and provide the promised yield, on-site inspection methods with portable test equipment (mobile PV test centres) are commonly used…
