Artificial Sun—A Stand to Test New PVT Minimodules

Abstract

Hybrid photovoltaic thermal (PVT) modules have gained more attention because of their benefits of higher total efficiency and lower gross area of installation in comparison with photo-voltaic (PV) or solar thermal collectors (T). Although international standards for separate panels, photovoltaics, or thermal collectors are available, the lack of testing procedures for PVT panels is a problem, especially if a high level of integration between the two parts is implemented. In the paper, a new stand to test new PVT minimodules is proposed and verified. It allows a reduction of the influence of environmental conditions on the tested T or PVT structures. Research conducted on lamp configurations confirms the possibility of achieving a high uniformity of light intensity, with values close to the AM1.5 spectrum standard (1049 ± 34 W/m2). The first measurements of new PVT minimodules have proven their usefulness, as well as the potential of a new hybrid solution.
