Borja, S.K.L.
The goal of this study is to present a GIS-based method for selecting grid-connected solar farm installation sites using a combination of Analytic Hierarchy Process (AHP) and weighted goal programming (WGP). The GIS was used to eliminate infeasible locations based on land type land cover, protected areas, roads, aspect, and slope. AHP-WGP was used to select the installation locations of M number of solar farms considering six criteria-total energy produced, distance from transmission lines, distance from roads, distance from built-up areas, installation cost, and maintenance cost. The weight of each criterion was composed using AHP, WGP was implemented to select the M solar farm installation sites that best satisfy the decision-makers' preferences. The performance of the AHP=WGP approach was evaluated against the suitable locations found using the Technique for Order of Preference by Similarity to Ideal Solution (AHP-TOPSIS approach). Occidental Mindoro, Philippines was used as the study site. The feasible installation sites selected using AHP-WGP were located near roads and transmission lines while the installation sites selected using AHP-TOPSIS were less accessible and more costly.
