This chapter evaluates module architectures and units of photovoltaic cooling systems, aiming to determine, select and design a modular system that can be applied in a real-scale photovoltaic power plant (PVPP) in order to enhance the yields of electricity production (entitled cooled photovoltaic plant). An analysis of the local climatic, geographic and solar conditions as well as construction, operational and maintenance aspects was carried out. Worldwide, there are three main types of cooled photovoltaic systems: PVT liquid and air collectors, PV ventilated with heat recovery and non-PVT systems. Based on the local weather conditions (tropical warm and dry) with both temperature and solar irradiation index being high, it results the PVT-liquid system to be more suitable in a scenario with available cooling fluid. We conclude that the best design and arrangement of the cooling system are of the type coil and multiple channel because they permit better rates of heat exchange between the cooling fluid and the PV module.

The objective of this work is to identify the premises and strategies for the design of a zero-energy solar house and propose the systematization of its process. The focus of the application is on the single-family residential typology. The method consists of analyzing the whole process from the initial phase of the architecture project to the use of automation systems, aiming at the best use of solar energy in terms of sustainable development and high energy efficiency. Each phase of the process has significant importance in the performance of the residential unit, however, the influence that one phase has over another plays a fundamental role in the final result. The process of systematization encompasses all these phases, starting from the demands for energy in a solar house and introducing strategies to meet these demands. The prototype of the zero-energy solar house is used as an example of the application of this process for the development of a parametric solar house. The results show a strong positive correlation of linear dependence between the assumptions and strategies used in the architecture of the house and the solar system, allowing a conclusion of the dependence relation on sustainability, thermal comfort, visual and energy efficiency.
