There are many factors that alter the performance of a module: dirt, shading, uneven aging and the output that can vary by ± 3% depending on manufacture. These are sufficient to generate ~ 2% total energy losses.

To minimize these losses, we create a system that responds to these risks that cause a decrease in energy production during the useful life. Thus we avoid losses due to mismatch between modules; ensuring that the weakest do not affect the performance of the strong.
