TLDR
The study has reached the conclusion that, the more the degree of parallelism, the less the effect of fault condition on module output maximum power.Abstract:
This paper has proposed two assembling configurations of cells inside a module. These developed techniques have been intensively discussed to synthesize the effect of cells configuration on module losses. The study has reached the conclusion that, the more the degree of parallelism, the less the effect of fault condition on module output maximum power. An alternative configuration realizing the same advantage of reduced losses is achieved by series-parallel configuration.read more
