Maximizing PV module harvested output power using a computer based automatic sun tracker

In the present work, a computer based photovoltaic sun tracker module is designed and implemented. Monitoring, controlling, and recording features are fully obtained in the present system using an efficient programming environment Design equations which are implemented allow the usage of the system anywhere anytime without extra hardware tracking circuits. A carefully design hardware motor deriving circuit is designed and implemented to simplify the controlling program without scarifying the required accuracy. The system generates the motors' controlling signals to allocate the photovoltaic module to receive the maximize amount of the solar energy on its surface from sunrise to sunset. The proposed system is successfully implemented for photovoltaic modules under realistic operating conditions.
