Resumen

This paper presents the hardware implementation of a linear estimation algorithm for the online monitoring of temperature-dependent parameters from photovoltaic (PV) systems. Such parameters are related to the optimal energy efficiency in PV panels, and the validity of the estimation algorithm has been verified in prior publications. The algorithm requires the sampling of high-frequency harmonics in the DC-DC converted voltage and current signals (in the order of several hundred kHz), which make their acquisition and processing unwieldy for typical small embedded systems, mainly if aiming at low latency, efficiency control loops for several panels. As such, the presented system provides with fast sampling (1Mbps per channel), fast processing, expandable parametric estimation, and online monitoring, using an Avnet ZedBoard Zynq SoC platform. Monitoring data from the system may be accessed via the Internet, and the low resources count of the implemented system opens the possibility for the incorporation of control algorithms running on hardware as well.
