Cost of energy and mutual shadows in a two-axis tracking PV system [PDF]

open access: yes, 2012
The performance improvement obtained from the use of trackers in a PV system cannot be separated from the higher requirement of land due to the mutual shadows between generators.

Impact of Degraded Photovoltaic Modules on Maximum Power Extraction in Series-Parallel Photovoltaic Arrays

open access: yes
Photovoltaic (PV) arrays operating under maximum power point tracking (MPPT) are commonly analyzed under the assumption that total extractable power can be estimated by summing the individual module maximum power points. In practice, however, electrical mismatch caused by module degradation, aging, or non-uniform operating conditions can invalidate ...
