Towards the Design of Microcontroller Based Embedded Sensory systems with a Five-Parameter Single Diode Estimation Method for Photovoltaic Panels

We here propose the extension of the Arduino Based Embedded Sensory systems Design of a five-parameter single diode estimation method for photovoltaic panels. The first attempt shows how to implement an already proposed algorithm into a micro controller-based system embedded in the PV panel module communicating with a long-range commercial high-frequency radio transmitter. Concerning the five parameter estimation method, it is based on an iterative algorithm, to estimate the parameter of the electrical single-diode model of the panel starting from the panel's datasheet. The proposed very low-cost architecture can be further integrated into a single chip apparatus in order to be implemented directly in the panel embedded electronics.
