Resumo

Por várias décadas, a eletrificação rural permaneceu um desafio formidável, particularmente na Nigéria. Restrições financeiras, terreno rural difícil, políticas ineficientes e falta de desenvolvimento da comunidade industrial contribuíram para o problema de expansão da rede nessas áreas. Essas áreas são deficientes em energia e suas demandas de energia para acompanhar a tecnologia de comunicação de ponta estão aumentando constantemente. Como resultado, as áreas rurais são confrontadas com a questão da cobrança. Consequentemente, muitos residentes rurais são forçados a depender de geradores a diesel/gasolina ou viajar longas distâncias e pagar um valor extra para carregar seus telefones celulares. Assim, este artigo propõe um sistema de carregamento movido a energia solar fora da rede como uma solução alternativa e sustentável para atender à demanda de energia de telefonia móvel rural. A metodologia empregou características arquitetônicas de seis camadas, com a métrica de comparação econômica baseada no valor presente líquido e no período de retorno. Além disso, a análise de desempenho do modelo proposto revelou que a taxa de carregamento depende do tipo de bateria do telefone e do tipo de carregador. Além disso, o sistema de carregamento móvel fora da rede tem um valor presente líquido mais alto (US$ 20.658) e um período de retorno mais curto de 2,5 anos do que o investimento alternativo de um gerador a gasolina.
