# Energy Efficiency Improvement in Reconfigurable Photovoltaic Systems: An Evaluation of Team Systems
## 8 Conclusions  
This work deals with some aspects related to the sizing ratio (\(R_{S}\)) of GCPV systems and the relationship of this parameter with the available power at the output of the PVG. Additionally, the optimum value of the sizing ratio (\(R_{S\,OPT}\)) of a GCPV non-reconfigurable system was defined as the one that maximizes the yearly energy efficiency (\(\eta_{E}\)) in the considered systems. A procedure to determine this optimum value has been presented. This procedure will be adapted to address the determination of \(R_{S}\) in reconfigurable GCPV systems.  
Systems with adjustable \(R_{S}\) have been defined, differentiating between systems that adjust the \(R_{S}\) value by modifying the rated power of the energy-processing subsystem used at each moment (called MIX or Multimaster systems), and systems that adjust the \(R_{S}\) value by modifying the nominal power of the PVG connected to each energy-processing system (called team-based systems).  
This presented work addresses issues related to the design of reconfigurable photovoltaic systems based on the team concept and the required control. An experimental setup for testing GCPV systems based on the team concept is described. A set of emulation tests for the characterization of these systems are described, and the obtained results are presented.  
The results obtained from conducted emulations demonstrate that the reconfigurable systems exhibit superior performance on the defined as \"cloudy\" and \"partly sunny\" days when compared with non-reconfigurable systems. However, on the defined as \"sunny\" days, a slight variation in the energy generation is observed.  
The notable variation observed in the energy production on \"cloudy\" and \"partly sunny\" days suggests that the utilization of team systems in regions characterized by low average irradiance would be advisable. Conversely, the marginal gain obtained in the results during a \"sunny\" day emulation indicates that employing the team system in areas with exceptionally high average irradiance may not substantially affect the system's energy efficiency and, as a consequence, its utilization is not advisable.
