Potencial.solar tool

Photovoltaic solar energy has the capacity to convert areas with predominantly residential and commercial uses into poles of energy generation centers. By the end of the first half of 2021, Andorra will have 107 photovoltaic installations integrated into buildings, with an installed capacity of 2 638 kWp. Although the growth in recent years has been important, the potential to be exploited is still very large.

potencial.solar provides orientative information on the energy potential, economic efficiency and environmental benefits of hypothetical photovoltaic solar energy installations on the rooves of buildings in the Principality of Andorra.

The photovoltaic potential of the rooves has been calculated using a large-scale methodology [1]. In this sense, the results presented do not replace a specific technical analysis carried out by an engineering bureau, but help to identify potentially interesting areas and rooves. This report provides a more detailed description of the methodology used and its limitations.

The large-scale analysis carried out includes 11 109 buildings, with a photovoltaic generation potential of 266 GWh/year (48% of the current electricity demand), with an installed capacity of 229 MWp. More detailed results are presented in [2], as well as a discussion of the energy self-sufficiency capacity of cities.
