The notable protagonism of bifacial modules in the photovoltaic market has triggered the need to estimate surface albedo more accurately. Some types of soil can have optical characteristics that optimize the generation of bifacial plants. In semi-arid Brazil, a region with high solar potential, the typical soil used in photovoltaic plants is sandy. With this in mind, the aim of this study is to evaluate the performance of four albedo models in the literature and a simplified model proposed for sandy soil in the region of Petrolina, Pernambuco. In this analysis, constant, univariate and bivariate models were considered. The bivariate model, which takes into account the diffuse fraction and the zenith angle, showed significant gains in estimating soil albedo, corresponding to a 30.6% improvement in nRMSE, with a difference of almost 4% in relation to the constant reference model (average value). It was also observed that depending on the availability of diffuse fraction measurements, it is advisable to apply univariate models that take the zenith angle as input, whose improvement can reach 15.3% in nRMSE and a difference of 1.9% compared to the constant models.
