Bifacial gain of rooftop solar PV
We accurately simulate the performance of bifacial solar panels on rooftop installations in our new study. We find that light roofs, which are common in Australia, could improve annual energy output by more than 20%.

Agrivoltaics Enhances Solar PV and Vineyard Performance
| Jul 03, 2026
Integrating solar PV above Mediterranean vineyards improved photovoltaic performance by reducing module temperatures and increasing rear-side irradiance for greater bifacial energy potential. At the same time, grape yield and sugar levels were maintained while berry acidity improved, supporting both renewable energy generation and climate-resilient viticulture.
Comparison of view factor and ray tracing models
| Jun 03, 2024
Highlights • Comparative analysis of View Factor (VF) & Ray Tracing (RT) models for bifacial PV. • Both models perform similarly for front illumination, RT performs better for rear. • VF overestimates module rear irradiance by 6.7% due to frame & structure shading.
Bifacial gain of rooftop solar PV systems
