Simulations of Efficiency Improvements Using Measured Microgrid Data

Abstract

Reaching unelectrified populations in the developing world with distributed solar requires agressive cost optimization of generation and storage. Conventional solar generation architectures using photovoltaic panels, sealed lead acid batteries, and inverters show room for cost improvement. Using data collected from photovoltaic microgrid users and simulations we demonstrate potential cost reductions using alternate technologies and architectures. Reducing losses from power conversion could lower wholesale energy costs by 20% while improved battery chemistries could lower costs by up to 50%.
