- 6. • Ongoing boom of new PV installations (Source: IEA 2017 - Snapshot of Global Photovoltaic Markets 2016) More than 100 GWp of new PV installations in 2017 As the relevance of solar power plants increases, the importance of the underlying system quality also increases! Development of worldwide PV Market
- 7. What‘s better? Both PV modules appear to be equal…
- 8. • Example: Detection of micro cracks through electroluminescence Module 2Module 1 Hidden Surprises can be made visible! …but “invisible” Micro cracks can lead to power losses over system lifetime.
- 9. • PV modules with low quality result in serious investment risks !High failure risk Low quality PV modules result in serious investment risks Examples for PV Module Failures
