A Simplified Urban-Scale Rooftop Photovoltaic Potential Estimation

This paper aims to provide a simple yet effective estimate of urban-scale rooftop photovoltaic potential using only open-source software and publicly available data. The suggested methodology is presented in a sample location in Bratislava, Slovakia. Although many papers are published in similar areas, very few reveal the specific steps and functions in the software used, or the computational core of some part of the estimation is a paid service. Using our methodology, it is possible to obtain basic irradiation parameters and photovoltaic generation in the area. The great advantage of this model is its scalability and the easy way of modifying every computational parameter. The results and limitations of the proposed methodology are discussed, and further development is suggested.
