Design and implementation of maximum power point tracking solar charge controller

Solar or photovoltaic (PV) system is an alternative clean energy resource that has received much attention in the research and industries. Solar charge controller (CC) is the heart of a solar system. Three common types of charge controller are ON/Off, pulse width modulation (PWM) and maximum power point tracking (MPPT). MPPT is getting very much popularity nowadays for its high capability of power extracting from solar panel. This paper is presenting here an improved design of MPPT solar charge controller using Aurduino. The proposed technique significantly reduce system power loss and increase the efficiency. Experimented highest efficiency 97.75% is recorded from the proposed system. Additionally, some new features are added like smart device charging, wireless data logging and protections from high voltage disconnect (HVD), low voltage disconnect (LVD), over current protection, short circuit protection and reverse polarity protection.
