At the SEAC outdoor research facility SolarBEAT a test program started aimed at special PV modules consisting of a large amount of small PV cells. The PV cells are down to 1/16th of the normal size. The idea behind it is that these modules perform much better in non-ideal situations in the built environment, where partial shading frequently occurs. This so called TESSERA concept is developed within the Scalable Shade Tolerant Module (SSTM) project, supported by the TKI Urban Energy. The project aims to determine the feasibility of the concept, based on the criteria of manufacturability, industrialization, lifetime and levelized cost of electricity (LCOE).
The new TESSERA modules undergo a 9 months test program in outdoor conditions. The field test consists of 6 full size TESSERA module prototypes connected to micro inverters from Heliox. As a comparison on the same location are two reference systems with standard PV modules: with a string inverter and with micro inverters. All three systems in the test setup are installed at SolarBEAT, the outdoor test facility of SEAC. SEAC performs system performance analysis, shading experiments, components efficiency calculations and failure analysis.
