PVT technology is an essential part of a sustainable and future-oriented power supply. Previous, its market potential still remains unexploited.

A key finding is that the reliability and durability of PVT modules are especially challenged at elevated temperatures and higher humidity loads. The test methods available from the IEC and ISO standards are covering the specifics of PV and ST module’s, most of which are similar for PVT modules, too. Yet, the PVT specific load collectives and the operating conditions arising from the system integration of PVT are only partially covered in the set of existing standards (e.g. stagnation temperature approval, mechanical load resistance). Moreover, the warranties of existing PV modules set equally high consumer expectations in regard to PVT collectors, but it is not self-evident that PVT technology can comply with these expectations. Therefore, further investigations will be necessary in order to achieve a sustainable market development. We hope this report will contribute to this development by illustrating the state of the art and by pointing out where more research is needed.

Abstract

PVT technology is an essential part of a sustainable and future-oriented power supply. Previous, its market potential still remains unexploited. Previous Task 60 reports have presented the current market situation of different PVT systems as well as the subsidy practices in regard to PVT technology [IEA SHC Task 60]. In order to achieve a sustainable PVT market development, reliability of product quality is another key factor, and it can only be achieved by establishing functioning standards. This report therefore aims at displaying the Status Quo of PVT Characterization in order to support PVT technology in its further development and applications. The report is hence of interest for researchers as well as public and private sector stakeholders. A key finding is that the reliability and durability of PVT modules are especially challenged at elevated temperatures and higher humidity loads. The test methods available from the IEC and ISO standards are covering the specifics of PV and ST module’s, most of which are similar for PVT modules, too. Yet, the PVT specific load collectives and the operating conditions arising from the system integration of PVT are only partially covered in the set of existing standards (e.g. stagnation temperature approval, mechanical load resistance). Moreover, the warranties of existing PV modules set equally high consumer expectations in regard to PVT collectors, but it is not self-evident that PVT technology can comply with these expectations. Therefore, further investigations will be necessary in order to achieve a sustainable market development. We hope this report will contribute to this development by illustrating the state of the art and by pointing out where more research is needed.
