The photovoltaic (PV) panel makes it possible for everyone to produce electricity in their own house. However, the panel is quite a costly investment and requires much consideration to maximize its potential. The roof has variables that would impact electricity generation. The roofs of houses in Indonesia were generally built in a complex shape, a combination of gable and hip roofs. This research was conducted to break down factors affecting PV productivity with regard to the roofs aspects. A computer simulation using the Ladybug plugin in Rhinoceros software has been done to achieve the target. Initially, the performance of PV panels on the gable and hip roof is analyzed separately. It is found that the roof’s slope and orientation contribute more to the amount of electricity produced than the shape itself. These factors were used to assess the PV potential in several housing models employing simple and complex roof (more than 2 surfaces) construction in the city of Gorontalo. Eventually, a comparison between the estimation of real PV production on housing and the estimation provided by the simulation is conducted to verify the assessment method. The difference is about 4%, which is proof that the simulation result is reliable. © 2022, Intelektual Pustaka Media Utama. All rights reserved.
