Distributed strategies of MPPT in PV modules

Since 2010 module level power electronics (MLPE) market has not stopped growing and gaining market share and the predictions are that the tendency continuous this way, especially in distributed generation PV systems. In 2013 MLPE accounted for a 4% of the total inverter market and in 2012 54% of the residential PV systems installed in the United States were done with MLPE. These numbers justify that theoretical and experimental studies on DMPPT are performed and keep on being performed in the future in order to fully understand the technology. Despite the large growth in market share of these products the number of publications on this topic is still very small.

Another interesting option of MLPE is that the working values of each module are monitored. This permits knowing which exact module is under-producing reducing the maintenance costs in a case of failure. However, even more interesting is the failure diagnosis possibilities that this provides if a look into the voltage and current values of each module is taken.
