This study aims to compare 4 scenarios of solar rooftop photovoltaic system technology that is used in the industrial segment in two different locations in Indonesia. Comparisons were made using energy, economic and environmental analysis methods and continued with optimization using linear programming methods. The results of the study show that scenario 2 solar photovoltaic system can produce more electrical energy and CO2 that can be reduced than in the other scenarios. While scenario 4 solar photovoltaic system is a scenario with better economic value and optimal benefits value than the other scenarios.
