Proposta de mapeamento do potencial de radiação solar em edificações com o uso de drone

Abstract

This work presents a methodology to quantify the potential of photovoltaic electric production from the daily solar radiation potential calculation for multiple buildings in urban environment. For this purpose, data raised using drones are used and their processing is performed in GIS environment, through the hemispheric sighting algorithm together with the simple equation of transmissivity of solar radiation. The methodology uses a digital surface model and the orthophoto obtained by drone to, respectively, perform the solar radiation analysis by area and vectorize the roof limits of the buildings. The radiation values are individualized for each property when applying the zonal statistics. The results obtained in an area of the Pampulha region, in Belo Horizonte, allowed to quantify the radiation potential at 2.77 to 4.85 kWh / m² / day for each building surveyed, which makes it possible to individually evaluate the economic value of the production obtained. by installing photovoltaic panels in each property raised. The methodology can be used as a relevant tool to promote energy sustainable cities, as well as public policies for decentralized energy generation.
