Abstract

The energy efficiency of buildings plays a significant role in the development of distributed power generation in the city. The complex of energy-saving measures to improve the energy efficiency of buildings includes the development of structures and engineering systems using renewable energy sources, such as combined photovoltaic-thermal modules (PVT modules), which unite photovoltaic modules and solar collectors in one design. The use of PVT technology makes it possible to increase the electrical performance of solar cells due to their cooling during operation. The purpose of the article is to assess the energy characteristics of the PVT module in the course of experimental studies. A solar PVT module has been developed, containing a protective glass coating and connected solar cells placed between the glass and the casing with a coolant channel of a rectangular cross section. A system has been developed for automatic recording of the main parameters of the PVT module during field studies, which allows the energy characteristics of the module (including current–voltage characteristics) to be recorded with the required frequency, followed by storing the data array in a convenient form for further processing. The article presents a series of current–voltage characteristics measured during field studies and power curves of a PVT module for various values of total insolation and the specific coolant flow rate. At a specific coolant flow rate varying from 18 to 165 L/(h m2) and a total insolation of 880 W/m2, the specific thermal power of the module varies from 452.78 to 518.41 W/m2, and the specific electric power varies from 70 to 87 W/m2. The developed design of the PVT module allows an increase in the electrical performance by 10–20% compared with conventional photoelectric modules. The proposed design of the PVT module installed on the roofs and facades of buildings can solve the problem of the lack of space for solar energy facilities in urban areas and provide heat and electricity to consumers in the residential and public sectors.
