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.
