Photovoltaic potential and land-use estimation methodology

This paper aims at improving the clarity and coherence of PV (photovoltaics) technical potential assessment, that is, calculation of the electricity that can be supplied by large-scale deployment of PV systems. A step-by step method, compiling the main variables and processes involved, and including the packing factor in the technical potential equations, is proposed for this purpose. The influence of latitude and some design parameters, such as the shading criterion and tilt angle is analyzed. The paper supplies easy-to-use tools for estimating technical PV potential, as well as PV system land-use requirements. Analytical expressions and graphic examples, and a comparison of some case studies with existing PV plant data are included. (C) 2015 Elsevier Ltd. All rights reserved.
