Abstract—This research paper presents a methodology that helps to increase the profitability of a classic manufacturing process through the energy indicator and the integration indicator. This solution was applied in a manufacturing company that uses distributed photovoltaic energy generation. The company produces its own products and injects energy into the grid. The prices obtained through each solution, the unit price of the manufactured product and the energy consumption per unit of product are taken into account. The results indicate that this methodology constitutes an optimal solution for the use of electricity obtained from photovoltaic systems. The profit achieved by the company is maximized. The methodology can be used by manufacturing companies by integrating components necessary for the work process into manufacturing.
Keywords—measurement indicators/markers, product cost, non-renewable resources, objectives, sustainability strategy
