Using a solar simulator, a photoelectric-thermal system integrated into an open-loop
air building with a working fluid was experimentally investigated. Options for building-integrated
photovoltaic/thermal systems and systems using polycrystalline silicon photovoltaic panels were
explored. Options for building-integrated photovoltaic/thermal systems and systems using
polycrystalline silicon photovoltaic panels were explored. Experimental results show that the
efficiency of equivalent system and PV panels in building-integrated PV/thermal systems, the bottom surface in the cavity of building-integrated PV/thermal system sometimes achieves high thermal
efficiency due to solar radiation absorption.
There are various ways to solve this problem, and the Solar Simulator creates accurate and
repeatable test conditions in terms of solar radiation, wind speed and ambient temperature, allowing
the prototype to be tested in a stable, near-room temperature environment. Lamps that simulate
sunlight under stable conditions produce radiation close to the solar spectrum. The fan creates winds
of varying speeds parallel to the surface of the PV panel in the same direction as the current in the
cavity.
Thermal efficiency of the insulating layer, which supports the structure of the integrated
photovoltaic/thermal systems of the building, at an angle of inclination from 0 to 180 degrees, the
solar radiation drop in the simulator is from 880 to 940 W/m2
, the average wind speed is from 2 to
3 m/ s.
Theoretical and experimental studies were carried out to determine the change in the
temperature of the air passing through a system with a photo and photoheat exchanger, taking into
account room temperature and the radiation intensity of the solar simulator.
