In the latest years, some optimization technologies<\/strong> \u201cat the module level\u201d have established in the photovoltaic sector. These can be used both in existing plants<\/strong>, with the aim to improve the plant characteristic, e.g. in the case of partial shadows, and in new plants<\/strong> for additional features as monitoring or the possibility to increase performances.<\/p>\n

Make the most of the energy captured by the MPPT function<\/h2>\n

An important task of the electronic part connected to the modules in a photovoltaic plant is to make the most of the captured energy<\/strong> by a function said MPPT<\/strong> (Maximum Power Point Traker). This function is usually performed by the inverter which can have one or more independent channels that can pursue that aim.<\/p>\n

MPPT functions performed by the inverter<\/h2>\n

In the vast majority of the existing photovoltaic installations, the inverter performs the MPPT function and this is beneficial as the photovoltaic modules are as uniform as possible, exposed with the same inclination and orientation\u00a0 and without shading.<\/p>\n

What to do in case of shading<\/h2>\n

In case of shading<\/strong>, or when photovoltaic modules are not always the same or are installed in different modes<\/strong>, it is convenient to evaluate optimization systems at the \u201cmodule level\u201d, which implement the MPPT function for each photovoltaic module<\/strong>.<\/p>\n
