Energia solar fotovoltaica em instituições de ensino: estudo de caso ITM campus Robledo
Conteúdo do artigo principal
Resumo
The work shows a technical, environmental and economic analysis of the integration of photovoltaic solar technology, with the interconnected network that currently supplies electricity to the Metropolitan Technological Institute, Robledo campus, for the 2015-2019 period, and considering three scenarios; 80,000, 100,000 and 120,000 kWh of monthly demand covered with this renewable source. The installation, using polycrystalline solar modules, avoids the emission of large amounts of CO2. For the 80,000 kWh / month system, a 75,79 % reduction in greenhouse gasses emissions associated with electricity consumption from the national interconnected system is achieved. With 100,000 kWh/month, a reduction of 95,41 % is achieved and with 120,000 kWh / month, a reduction of 95,58 %. In economic terms, the financial indicator IRR (internal rate of return) is calculated for a time horizon of 5 years and considering the savings in the purchase of electricity as income. The best scenario would be 100,000 kWh / month, since this presents the highest IRR, initial investment, lower installation and maintenance costs, while that of 120,000 kWh / month presents a lower IRR and higher operating costs.
