This paper presents the design and the realization of data acquisition system measure, to record and to maximize solar panel power. The special feature of this system is the short sampling time that allows tracking of fast variations in solar irradiance. It was designed to operate autonomously hence; low power consumption and local data storage capabilities(More)
