Demonstration of a governamental initiative through the installation of photovoltaic modules in social projects

Abstract

In 2022, solar energy generation through photovoltaic modules saw a remarkable 26% increase, reaching nearly 1300 TWh, solidifying its status as the renewable energy source with the highest annual growth rate. This trend has sparked substantial investments from major European powers, the United States, and China (International Energy Agency - IEA 2022). This article aims to assess the feasibility of the Brazilian government implementing photovoltaic modules in low-income and peripheral households to align with global trends and mitigate energy costs during dry periods. Data from photovoltaic energy companies in Brazil and abroad were compiled for analysis, considering various module types and efficiencies. The study, conducted using Python for data interpretation through tables and graphs, concluded that solar irradiation is uniformly distributed across the country, making the project viable nationwide. Calculations showed profitability for a single household, with an estimated implementation cost of R$21,000.00, achievable after 24 years, yielding an approximate profit of R$5,640.00 over the module's 30-year lifespan. This underscores the viability of a profitable government initiative aligned with UN Sustainable Development Goal 7, reducing CO2 emissions from thermal power plants and cutting electrical energy costs.
