Testing, certification and standardization of BIPV roofs.

Reference number
Coordinator Sunroof AB
Funding from Vinnova SEK 100 000
Project duration November 2017 - March 2018
Status Completed

Purpose and goal

The project´s goals have been met as tests conducted demonstrate that standard-size solar modules can be mounted in such a way that they function as a roof surface like tiles. Furthermore, RISE testing has given better insight into how the surface layer behaves in strong winds and heavy precipitation. Some details in the design have been adjusted according to these experiences.

Expected results and effects

The test was performed with the minimum roof inclination that still not count as "non-low-inclination-roof" (14 °) to test with the most difficult prerequisities. Tests showed that the BIPV system prevents water from entering layer beneath modules also at large amounts of precipitation. However, when the wind force becomes strong enough, water is pressed in between the solar modules. It was an expected result and does not pose a problem as the BIPV system is for mounting where underlying membrane is the seal of the roof, just like a roof tile.

Planned approach and implementation

Sunroof has built up a trial set up with the Research Institute of Sweden (RISE), consisting of a building integrated photovoltaics (BIPV) roof segment. On this RISE has conducted test resistance to heavy rain and strong winds in accordance with SS-EN 50583-2: 2016. The test was conducted in two rounds where the first showed a flaw in sheet metal works, which was corrected, so that the test was then completed in a second round.
