2. Energy sizing of PV systems

2.1 Sizing PV systems

PV systems are inherently complex: the MPPT function is emblematic of this systemic aspect. We have identified a huge variety of possible structures and architectures, and shown how the energy productivity of the PV generator depends on many factors. Its dependence on the local solar deposit is naturally a very specific primary property.

This is particularly the case for stand-alone or isolated PV systems that have to provide a given energy service. Disconnected from a large, very powerful public grid, the autonomous isolated network only has a finite amount of power, as its stable operating limits are easily reached, and are an integral part of its optimal design and implementation in order to avoid strong oversizing, synonymous with...
