Maintenance and evaluation during the design of building integrated grid-connected photovoltaic systems

This paper describes and analyzes general conclusions about how the design of a photovoltaic installation can affect the maintenance and evaluation tasks when using just classic parameters. Due to the sole use of classic parameters, it is more difficult to make an effective monitoring of the installation actual operation and suitable maintenance tasks. This situation worsens when the grid-connected PV system is a medium power system, a high power system or has a centralized inverter. These conclusions are the result from the experience lived during the design, implementation, evaluation and maintenance of a 200-kWp photovoltaic plant integrated at the Jaen university campus. We include some solutions to be considered during the design in order to make the measurements, monitoring and maintenance tasks easier.
