(author)Nearly 840 million people still lack access to electricity, while over a billion more have an unreliable electricity connection. In this article, the three different electrification pathways-grid extension, centralized microgrids, and standalone solar-based solutions, such as pico-solar and solar home systems (SHS)-are critically examined...journal article 2020

Narayan, N.S. (author), Chamseddine, Ali (author), Vega Garita, V.E. (author), Qin, Z. (author), Popovic, J. (author), Bauer, P. (author), Zeman, M. (author)Off-grid solar home systems (SHSs) currently constitute a major source of providing basic electricity needs in un(der)-electrified regions of the world, with around 73 million households having benefited from off-grid solar solutions by 2017. However, in and of itself, state-of-the-art SHSs can only provide electricity access with adequate...journal article 2019

Narayan, N.S. (author), Chamseddine, Ali (author), Vega Garita, V.E. (author), Qin, Z. (author), Popovic, J. (author), Bauer, P. (author), Zeman, M. (author)With almost 1.1 billion people lacking access to electricity, solar-based off-grid products like Solar Home Systems (SHS) have become a promising solution to provide basic electricity needs in un(der)-electrified regions. Therefore, optimal system sizing is a vital task as both oversizing and undersizing a system can be detrimental to system...journal article 2019
