Under the general case assumptions, the use of photovoltaics for on-site electricity production resulted in lower GHG emissions but at a higher per capita cost when compared to grid-tied electricity (Figure ). The photovoltaic energy configuration median per capita cost was 0.145 USD•Mg CO2-eq -1 in the general case scenario as compared to (for example) proposed carbon pricing of 34-64 USD•Mg CO2-eq -1 in the United States in 2025 to achieve net-zero CO2 emissions by 2050. Instead, the selection of a photovoltaic system may be driven more by a lack of access to reliable grid-based electricity (e.g., in rural settings or locations with unreliable electric grids). While the cost and GHG emissions of the general case provided an initial estimate of the relative sustainability of the NEWgenerator using a global average price ratio for BOM costs and global average emissions factors, understanding how contextual factors impact the economics and environmental impact of the NEWgenerator is necessary to inform intentional deployment decisions. All five countries had lower per capita costs than the general case because (i) the price level ratios for the five countries were less than 1.0 (the reference price level ratio of the U.S., 1.0, was used in the general case) and (ii) the country-specific consumables and grid-electricity prices are lower. Grid-tied configurations had lower cost but higher emissions than photovoltaic configurations in India, China, and South Africa, whereas assumptions of grid characteristics in Senegal and Uganda resulted lower cost and emissions for the photovoltaic configuration (Figure ). The daily cost of the grid-tied and photovoltaic configurations were below 0.114 and 0.100 USD•cap -1 •d -1 across all five countries, respectively. The estimated cost in India was the lowest of the five countries with median values for grid-tied and photovoltaic configurations of 0.090/0.069 USD•cap -1 •d -1 , respectively, followed by Uganda (0.099/0.093 USD
