Live recording of Dr. Malcolm Abbotts presentation from the 53rd IEEE PVSC 2025 in Montreal, covering spectral correction methods for yield forecasting of perovskite-silicon tandem solar modules. The talk explores how spectral effects are significantly stronger in tandems compared to conventional silicon cells, and demonstrates integration approaches for both advanced simulation software and industry-standard tools like PVSyst.

This is an extended version of the presentation given by Dr Keith McIntosh (PV Lighthouse) at the 2023 PVPMC workshop. It quantifies the difference between advanced and conventional models (such as those used in PVSyst, SAM and PVLib) for 8 physical mechanisms.

The study was presented at the 49th IEEE PVSC in Philadelphia 2022 and covers how module temperature depends on wind speed, wind direction and tilt and how best to model the module temperature.

What if solar modules were designed for real-world conditions rather than the datasheet? What if you could modify any physical feature of a solar cell or module and predict how it will behave once mounted in the field?

Do you know how much extra yield can be gained by optimising your tracker angle? In our recent presentation at the IEEE PVSC, Dr Keith McIntosh used SunSolve to show that the optimum angle for both monofacial and bifacial panels is NOT always directly facing the sun.

This is a presentation from the 47th IEEE PVSC 2020 covers Which modules produce more power in a two-high bifacial system, a comparison of simulation results to experiment, a breakdown of the factors that cause non-uniform illumination in two-high system and more

This is a presentation from the 47th IEEE PVSC 2020 and covers accurate prediction of bifacial modules in a tracking PV system, understanding sources of non-uniform illumination and cell to cell mismatch and comparison of simulation to experimental facility.
