Technical and energy feasibility of a photovoltaic system: pilot test in university dental laboratories

Abstract

Introduction: Photovoltaic solar energy is a technological alternative for reducing emissions and promoting the sustainable use of energy resources. In Colombia, its implementation is particularly relevant due to the high levels of solar radiation. The adoption of renewable energy in educational institutions contributes to environmental sustainability by reducing CO₂ emissions, mitigating the effects of climate change, and improving quality of life. Given that the operation of a dental prosthesis laboratory involves considerable energy consumption, the need to evaluate sustainable alternatives that benefit the institution, the region, and the country was identified. From a professional perspective, this initiative contributes to environmental sustainability through the incorporation of clean technologies. Objective: To determine the technical and energy feasibility of a photovoltaic system through a pilot test in university dental laboratories. Methodology: A quantitative, observational, descriptive study was conducted; energy consumption was evaluated, a 0.66 kWp photovoltaic system was installed, and monitoring was carried out for 14 months. Results: The system generated 1,113.48 kWh and prevented the emission of 408.57 kg of CO₂, covering 2.2% of the laboratory's monthly energy consumption. Conclusions: The pilot test confirms the technical feasibility of the photovoltaic system, its environmental contribution, and its usefulness as an educational tool, although greater installed capacity is required for significant energy impacts.
