Have you checked the November 2015 issue of IEEE IES Transactions on Industrial Electronics ? There is a special section on the precise topic of “Monitoring, Prognosis and Techniques for Increasing the Lifetime & Reliability of Photovoltaic Systems“. Here are the titles of the seven articles selected for this special section:

1- “Operation of cascaded H-bridge multilevel converters for large-scale photovoltaic power plants under bridge failures”

2- “Online two-section PV array fault diagnosis with optimized voltage sensor locations”

3- “Photovoltaic systems reliability improvement by real-time FPGA-based switch failure diagnosis and fault tolerant DC-DC converter”

4- “Model-based degradation analysis of photovoltaic modules through series resistance estimation”

5- “Dual-Kalman-filter-based identification and real-time optimization of PV systems”

6- “A survey on mismatching and aging of PV modules: The closed loop”

7- “Innovative automated control system for PV fields inspection and remote control”

In the context of the rise of PV systems for solar power generation and also the Internet-of-things (IoT), the timing for this publication is very good. This is exactly the type of information that needs to be generated by controllers (and sent to operators via IoT) to maximize energy-efficiency of PV systems AND also reduce any chance of unplanified downtime leading to loss of revenues.
