In this paper, the performances of two different configurations of the PVT air collector (PVTAC) were studied and compared with respect to three energy matrices: energy payback time, electricity production factor and life cycle conversion efficiency.Geometrically, both configurations are similar except one equipped with a flat plate collector (PVTACF) and other with a wavy plate collector (PVTACW). An experimental investigation was performed for both the models, located at Silchar (Latitude: 24.8333° N and Longitude: 92.7789° E) over a period of one year (May 2017 to April 2018). Initially, airflow velocity was varied between 1-3 m/s and ideal airflow velocity (2.5 m/s) was identified. The yearly energetic and exergetic performance was studied and presented. The overall annual energy and exergy of the PVTACW were achieved by 8.2 % and 2.3 % higher than the PVTACF. The energy payback time, electricity production factor, and life cycle conversion efficiency of the PVTACW were also achieved better than the PVTACF. The study provides useful information on the energetic performance and environmental impact of the PVTAC system under North-East Indian climatic conditions.

“…Most designs contain a frame housing an absorber with channels for circulation of the coolant, absorber of solar energy, transparent insulation located above the absorber, channels of input and output of working fluid and thermal insulation [3][4][5][6][7]. More productive is a solar collector containing a sealed housing, the upper part of which is made of a transparent material, and the inner surface facing the Sun has a dark coating that absorbs solar radiation, tubes with channels for the passage of coolant having an inlet and outlet on the surface of the solar collector [8]. Available solar driven water heating systems in the market, suitable to replace conventional electric water heater for multi-residential building.…”

In the conditions of the global ecological crisis in the world and Ukraine, the issue of finding alternative energy sources becomes relevant. One of the most common types of renewable energy is solar energy. In Ukraine today, the most promising direction of using solar energy is its direct transformation into low-potential thermal energy. To get electric power, solar radiation is the mere alternative to electric power generated from mined fuel, and without the pollution of air and water, or adverse consequences manifested in global warming. The disadvantage of this type of installation is the limitation of the duration of light time, as well as the effect of cloudiness. During the day, the number of solar radiation changes, to stabilize it is necessary to accumulate and accumulate it for further use, the technical implementation of stable operation of solar installation due to the use of terrestrial radiation and the accumulator of a specific part of solar energy is proposed. The purpose of the work is experimental studies to ensure the stable operation of the solar collector under cloudy conditions. The paper is aimed at the stabilization of the operation of the solar installation and to obtain additional heat after the Sun’s cloud cover. The use of a solar thermal collector is advisable in solar heating and hot water systems in conditions of alternating solar radiation. The results of physical modeling have proved the efficiency of the method of combining types of thermal radiation, due to the accumulation of energy it is possible to increase the quantitative index of solar energy in the conditions of cloudiness by 3 times Keywords: alternative energy, solar energy, solar collector, thermal energy, clouds, terrestrial radiation, ecology.
