Optimised use of green energy based on photovoltaic modules

Abstract EN

Operating point of solar photovoltaic cells depends on a lot of factors such as temperature, irradiance, load.

Any variations of one of these factors can change the photovoltaic cells output power.

This paper presents practical results for maximum power point tracking (MPPT) method using DC-DC converter and reconfiguration of photovoltaic (PV) modules method.

In order to continuously operate at maximum power, in real time, the system has to operate at the maximum power point MPP despite the changes in the climatic conditions.

MPPT increases the efficiency of operation of the solar modules.

The second method is based on selecting in real time, the photovoltaic array (PVA) optimum configuration for a given load and given working conditions, for a fixed number of modules.

Our aim is to extract the highest power of the direct coupling between the PV array and the load.

These methods allow a photovoltaic generator to produce the best continuous power
