Abstract The aim of this paper is to present a novel concept for control of hybrid photovoltaic-thermal systems: a Maximum Exergy Point Tracker. It operates by evaluation of the exergetic and energetic performance of a solar photovoltaic-thermal (PV/T) system, to find the maximum cell temperature that produces at least the same exergy as the system without cogeneration. This maximum working temperature is a very important issue for proper design of cogeneration plants and their operation. The operation with concentration showed better results for energetic and exergetic efficiencies, in addition to an increase in the maximum operating temperature of the photovoltaic cell, compared to operation without concentration. The results allow selecting a suitable photovoltaic cell for a given application, depending on its reference efficiency and temperature coefficient.

混合光伏-热力系统的最佳运行条件

摘要 本文的目的是提出一种控制混合光伏-热力系统的新概念：最大火用点跟踪器。它通过评估太阳能光伏热能 (PV/T) 系统的火用和能量性能来运行，以找到产生至少与没有热电联产的系统相同的火用的最大电池温度。这个最高工作温度对于热电联产设备的正确设计及其运行是一个非常重要的问题。与不集中的运行相比，集中运行在能量和火用效率方面表现出更好的结果，此外还增加了光伏电池的最大运行温度。结果允许为给定的应用选择合适的光伏电池，
