At the heart of floating solar: Singapore

By Dr Thomas Reindl, Solar Energy Research Institute of Singapore (SERIS)

Singapore operates the world’s largest testbed for floating PV, comparatively testing and evaluating 10 different floating PV installations from around the world, and held the first floating solar conference globally in October 2017. Writing exclusively for PV Tech Power, Thomas Reindl of the Solar Energy Research Institute of Singapore (SERIS) reports on a form of solar power whose huge potential is starting to be realised

Bifacial PV: comparing apples with apples sometimes does not make sense

By Dr. Radovan Kopecek; Dr. Joris Libal

Bifaciality is a complex area of PV technology and currently there is some confusion over what bifacial gains can be expected and how these transfer to system cost reductions. Radovan Kopecek and Joris Libal describe how bifacial gains are defined, what bifacial gains can be expected and what this means for real applications

Reducing uncertainty in PV yield assessments

By Mauricio Richter

When estimating the expected yield of a PV plant for financial risk assessment purposes, understanding the uncertainties of any model is crucial. Mauricio Richter of 3E investigates some of the emerging practices for obtaining and interpreting data to ensure the most accurate results

Mobile PV testing in India

By Satish Pandey

With India going all out to achieve its target of 100GW of PV by the year 2022, the quality of equipment used in installations is becoming increasingly important. Satish Pandey and Abhishek Sharma of Mahindra Susten explore the role of on-site testing in quality control, based on the early results from India’s first mobile PV lab

Failure assessments of PV systems demonstrate the importance of elective quality assurance

By Dipl. Ing. Annett Sepanski; Dipl. Ing. Uwe Hupach; Dipl. Ing. Willi Vaaßen; Dipl. Phys. Jörg Schmauder; Prof. Dr. Ansgar Steland; Thomas C. Sauer heads; Dipl., Dipl. ec. Georg Fischer; Dr. Andreas Sommer; M.Sc. E. Sovetkin

In a four-year project sponsored by the German Federal Ministry of Economics and Energy, a consortium of German experts assessed the quality of actual PV power installations. The researchers now report on how the effects of several common module failures on module and string performance highlight the importance of consistent quality assurance to prevent risks to financial success
