Solar Controller with Automatic Search Technology for the Maximum Power Point with Autonomy Display

In our work, we have been interested in conducting technological research on the use of photovoltaic energy for lighting. fact, produced a stand-alone system with automatic search maximum power point, consisting module, solar regulator, storage battery and digital control by microcontroller. The field is connected to input regulator its output. When voltage lower than regulation voltage, controller operates generator at Pmpp transfers this addition protection function, ensures tracking point (MPPT) allows deliver whatever variation climatic conditions (sunshine temperature). main role continuous monitoring state charge ensure against overcharging excessive discharging, coupling decoupling user as well maintenance. principle operation based controlling DC-DC converter rectangular “PWM” signal generated PIC16F874 microcontroller which also controls entire system. results simulation after realization were presented illustrate curves.
