Abstract

We developed a techno-economic model to simulate the performance of residential solar-battery systems as a means of reducing the reliance on backup generators in grid connected households in Lagos, Nigeria. We compared the economic and environmental performance of solar-battery systems to the technology options in households that may currently rely on backup generators to supplement unreliable grid service. Our analysis shows that solar-battery systems are economically profitable for households who rely on their backup generators to ensure at least 8-h of reliable service daily. We also show that the solar-battery systems could offer a cost-effective alternative for households intending to increase the level of the electricity services they receive without greater demand from backup generators. Finally, installing the solar-battery system lowers annual air emissions from households by 15 %–87 %. The paper proposes that policymakers provide access to low interest loans to improve the economic attractiveness of solar-battery systems across all the reliability preference levels.

尼日利亚拉各斯并网家庭屋顶太阳能电池系统的技术经济和环境评估

我们开发了一个技术经济模型来模拟住宅太阳能电池系统的性能，以此来减少尼日利亚拉各斯并网家庭对备用发电机的依赖。我们将太阳能电池系统的经济和环境性能与目前家庭可能依赖备用发电机补充不可靠电网服务的技术选择进行了比较。我们的分析表明，太阳能电池系统对于那些依靠备用发电机确保每天至少8小时可靠供电的家庭来说是经济上有利可图的。我们还表明，太阳能电池系统可以为那些打算提高电力服务水平的家庭提供一种经济有效的替代方案，而不需要更多的备用发电机。最后，安装太阳能电池系统可以使家庭每年的空气排放量降低15% - 87%。本文建议政策制定者提供低息贷款，以提高太阳能电池系统在所有可靠性偏好水平上的经济吸引力。

期刊介绍： Development Engineering: The Journal of Engineering in Economic Development (Dev Eng) is an open access, interdisciplinary journal applying engineering and economic research to the problems of poverty. Published studies must present novel research motivated by a specific global development problem. The journal serves as a bridge between engineers, economists, and other scientists involved in research on human, social, and economic development. Specific topics include: • Engineering research in response to unique constraints imposed by poverty. • Assessment of pro-poor technology solutions, including field performance, consumer adoption, and end-user impacts. • Novel technologies or tools for measuring behavioral, economic, and social outcomes in low-resource settings. • Hypothesis-generating research that explores technology markets and the role of innovation in economic development. • Lessons from the field, especially null results from field trials and technical failure analyses. • Rigorous analysis of existing development "solutions" through an engineering or economic lens. Although the journal focuses on quantitative, scientific approaches, it is intended to be suitable for a wider audience of development practitioners and policy makers, with evidence that can be used to improve decision-making. It also will be useful for engineering and applied economics faculty who conduct research or teach in "technology for development."
