Improving the efficiency thanks to the thorough analysis of the IV curves
As we saw before, SFV modules in perfect conditions can have different behaviors due to geometrical conditions, as it is the case of the installation we are analyzing. This situation significantly affects the production.
There are situations in which the bypass diodes of some SFV modules may come into operation, generating even greater losses.
Thanks to having the IV curve at SFV module level we can reconstruct the IV curve at String level, the reverse path is not possible.
Depending on the inverter power maximization strategies, the inverter could be set to a local maximum (around 90V) causing most of the SFV modules to be bypassed.
Due to this, it was decided to install a power maximizer on the two modules, which have a different inclination than the rest.
