Análise da influência da implantação de sistema de energia solar no valor de residências

Abstract

In view of the accelerated growth in the number of photovoltaic energy generation systems installed in homes, this work deals with their influence on the sale value of properties. For this, a study was carried out in a sample of residences in the city of Toledo, western Paraná. Data referring to 33 buildings that were for sale in the real estate market were collected. Data collection was carried out based on the variables that were considered to determine the value of the residences, such as private area, land area, number of suites, among others. In this work, the variable presence of a solar energy generation system was inserted, which has not yet been considered in the models for evaluating properties in the region. The direct comparative method of market data was used, and a linear regression model was generated that allowed evaluating the residences. As a result, it was possible to prove that the presence of the solar energy generation system in the residences influences the value of the properties, obtaining an increase of 16.97% in the appreciation of the residences that have the system, contributing to sustainability.
