ActivitiesSwiss BiPV Competence Centre research activities focuses on the integration of photovoltaic (BIPV) panels into buildings as building elements, such as conventional roof tiles, façade cladding, windows, shading devices or parapets. We offer planning, consultancy and concept development on all issues concerning energy systems and user comfort. Our investigations are supported by the most advanced simulation models. Monitoring campaigns and tests under realistic conditions (outdoor measurement) can also be used for evaluating new solutions or to validate new models.

ServiceThe development of building solutions able to satisfy architects is needed to ensure long-term and widespread acceptance: SUPSI is sup-porting this trend with the design of innovative BIPV products for new and existing buildings.

Our website (www.bipv.ch) provides essential information about PV technology integration to buildings and several project examples both in Switzerland and abroad.

The site includes the official list of PV modules and fastening systems, allowing the setting up of an integrated PV plant according to Swiss national regulations.

Customers◆ Support to architects and planners during the design phase,

with cost analysis in order to define the most suitable solutions and to calculate the return of investment (ROI)

◆ Development, support, testing and certification of new products for BIPV manufacturers

Indoor testing

◆ Full module characterisation

◆ Reference module definition

◆ Determination of energy prediction parameters

◆ Performance assessment


ActivitiesIndoor testing at the SUPSI PVLab is performed with two Class AAA pulsed solar simulators. The highest precision and repeatability is reached thanks to primary reference cells, spectral mismatch correction available at each flash and to round-robin campaigns with distinguished interna-tional research institutes.

Service◆ Current-voltage characterisation at Standard Test Conditions

(STC) with spectral mismatch correction

◆ Current-voltage characterisation at different irradiances and temperatures

◆ Determination of module parameters for PVSYST

◆ Spectral response measurements

◆ Module stabilisation through light soaking

◆ Current-voltage characterisation for concentrator cells up to 1200 suns

InnovationSUPSI developed his own spectral response measurement setup for commercial-size modules, both single and multi-junction, being among the fewest research centres worldwide in this topic. Through the calcul- ation of the spectral mismatch correction, the uncertainty of maximum power measurements at STC is further reduced.

The characterisation of modules under variable temperature and irradiance gives confidence on the performances under real operating conditions and allows to determine mathematical models to be used in PVSYST simulation software.

Outdoor testing

◆ Module benchmarking

◆ Product optimisation

◆ Energy yield test reports

◆ Customised BIPV outdoor test stands


ActivitiesThe monitoring and analysis of the kWh/kWp of a PV module under real operating conditions is one of the core activities of the SUPSI PVLab. The outdoor measurements are combined with indoor performance measurements (class A sun simulators) and, on request, with sever-al reliability tests (aging, mechanical stability and safety). Customised test stands can be developed for the investigation of special features (i.e BIPV, anti-soiling, increased shadowing tolerance, enhanced light trapping, etc.).

Service◆ Energy yield measurements under real operating conditions

◆ Remote data control with alert service

◆ Testing in different climates

◆ Validation of energy prediction models

◆ Determination of NOCT and NMOT

◆ Spectral irradiance measurement

◆ Design of test facilities

EquipmentAll measurements are performed with in-house developed, high precision, maximum power point trackers with IV-tracer capabilities (MPPT3000) and channels for the monitoring of irradiance and temperature.

The detailed energy yield reports are generated automatically and a sophisticated quality control procedure with alert functions allows the highest measurement accuracy available today.
