Abstract:

To maximize the yield of a photovoltaic panel, a mechanism called a solar follower was introduced. During the day, this gadget permits the panel to follow the sun. The method by which the tracker knows the position of the sun is given either by calculation (Clock or GPS system) or by a sensor (example an LDR sensor), As a result, the solar panel's efficiency is independent of the tracker's movement. We presented a solar follow-up system based on the monitoring of the fluctuation in Pmpp power supplied by the PV and managed by an MPPT (Maximum Power Point Tracking) to keep this power at its maximum during tracking correction. The control board activates the tracking motor as it observes the Pmpp power. The moment this power reaches its maximum, the tracking stops. A simulation study has shown us the reliability of this method, and real experience with an equatorial tracker allows us to conclude that this procedure offers great precision with the maximum energy yield extracted.
