Abstract

: Solar energy is one of the main
sources of renewable energy. In photovoltaic systems, energy is obtained from
photovoltaic batteries In photovoltaic batteries, the current and voltage do
not increase linearly. This causes the power to take different values. There is
a point where power reaches its peak. Detecting this point called the maximum
power point and transferring the energy to the load at this point, reduces the
losses and increases the efficiency. Many microcontroller controlled circuits
have been designed and algorithms have been developed for maximum power point
trackingPerturb and Observe algorithm is the most widely used algorithm. In
this study; Maximum Power Point Tracker Algorithm Based Solar Charge Controller
is designed. Arduino microcontroller card was used as it has easy
programmability and rapid prototype development. Developed charge regulator
determines the maximum power point by measuring the current voltage values and
charge the battery at this point. The current, voltage, battery charge rate and
charge status information obtained from the charge controller can be monitored
by android mobile devices. The developed charge control circuit has been tested
using a 45 Watt photovoltaic panel under different weather conditions. It was
observed that it followed the maximum power point.
