Abstract:
Human society has entered in a new stage of development, becoming an information and knowledge society [1]. This new level of society, marked by a complex and profound dynamism, requires a high energy consumption [2]. In this context, the world's energy reserves, based on fossil fuels (coal, oil, natural gas), are constantly declining [3]. By default, the price of these fuels and the energy produced by them becomes higher and higher. Consequently, renewable energy sources (solar, wind, tidal, geothermal) are becoming a necessity for the functioning of modern society [4]. These non-polluting sources support global efforts to reduce the negative effects of climate change, making a major contribution to reducing greenhouse gas emissions [5]. The activities of energy researchers are currently focused on the development of materials, devices and systems that allow a maximum efficiency of conversion of these alternative energies into electrical energy [6]. In the context of this transition of our society towards an energy future based on renewable resources, students must know and understand the principles and technologies of converting these types of clean energy into electrical energy [7]. Starting from this need, we initiated an interdisciplinary school project of Applied Physics in Technology: Green energy in schools - From solar cells to photovoltaic panel systems [8-14]. In addition to the didactic aspect, another very important reason for the elaboration of such a project was the fact that the geographical area in which we undertook this approach is solarized for most of the calendar year [15-16]. In this paper we have presented, for teaching purposes, a summary of the activities of design, building and implementation (at school level) of a smart system for converting solar energy into electrical energy, based on photovoltaic panels, with the possibility of real-time monitoring, via the Internet, of its functional parameters: voltage, current, power and electrical energy produced.
