In my previous article I presented the principle for avoiding production losses  when photovoltaic systems are located in such cases where there is shadow of  trees, dust, chimneys, antenna, other buildings … We speak of photovoltaic shading.
Then I presented a good solution to avoid these which is distributed MPP Tracking: one micro inverter per photovoltaic module to track individual Maximum Power Point. I also detailed 2 design approaches with pro’s & con’s arguments.
In this article, I will give some concerns and questions about photovoltaic reliability.

I will explain here the solutions and its principle for avoiding production losses  when photovoltaic systems are located in cases where there is shadow of  trees, dust, chimneys, antenna, other buildings or specific relief. The idea is to install one micro inverter per Photovoltaic module to track individual Maximum Power Point. I will detail 2 design approaches with their benfits & drawbacks.
