GUTIERREZ URDANETA, Luis; PADRON SUAREZ, Lenyer  and  VALLADARES AGUILERA, Javier. Marginal contribution of factors to energy gains of bifacial modules. Energética [online]. 2021, vol.42, n.1  Epub Mar 01, 2021. ISSN 1815-5901.

The introduction of bifacial panels in large-scale generation is relatively recent in the world. Studies carried out in other countries, by both academics and manufacturers, list several factors that influence the radiation reaching the back of the panel: the albedo, the elevation of the module, the distance between rows or trackers, the mounting structure of the module on the back and others. The authors performed 321 simulations of three sites with different latitudes, using fixed-tilt system (SAF) and horizontal single-axis tracking system (HSAT), and obtained six multiple linear regression equations. From them, the influence of the main factors affecting the generation in the SAF and HSAT systems with bifacial modules was quantified. The coefficients found for the different factors could be useful for future projects in Cuba, mainly because the available terrestrial surface is not unlimited.

Keywords : albedo; bifacial module; fixed tilt; solar tracking.
