Oh neat! I briefly pondered this same idea when first hearing about how cats have such good night vision (they have basically got a mirror _behind_ their light

  With agrivoltaics do the plants function like a mirror? I just saw article about this study; "Methodology for the estimation of cultivable space in photovoltaic installations with dual-axis trackers for their reconversion to agrivoltaic plants" (2024) https://www.sciencedirect.com/science/article/pii/S0306261924003350#f0040 https://www.sciencedirect.com/science/article/pii/S030626192... https://www.pv-magazine-india.com/2024/03/19/how-to-convert-pv-plants-with-dual-axis-trackers-into-agrivoltaic-facilities/ https://www.pv-magazine-india.com/2024/03/19/how-to-convert-... Albedo: https://en.wikipedia.org/wiki/Albedo https://en.wikipedia.org/wiki/Albedo : > Surface albedo is defined as the ratio of radiosity J_e to the irradiance E_e (flux per unit area) received by a surface. [2] IDK what a reasonable adjustment factor for dual-sided single-junction cells given crop albedo would be Technically, even with one-sided panels, it's probably actually necessary to also model light that bounces off a shiny crop back into the air above the panel and diffuses and reflects against other radiation and scatters back to the panel; it's probably necessary to model albedo (or reflectivity) for single-junction cells too.
