Most countries had higher GHG emissions than the general case, except for Uganda which was 1.4 and 18.7 kg CO2eq•cap -1 •yr -1 lower for photovoltaic and grid-tied sources, respectively. The grid-tied configurations across countries resulted in 28.6 -34.8 kg CO2-eq•cap -1 •yr -1 higher GHG emissions than their photovoltaic counterparts, except in Uganda which was only 6.3 kg CO2eq•cap -1 •yr -1 (Figure ). Observations unique to Uganda stemmed from the country's primary source of electricity, hydropower, which had a low GHG intensity but high unit cost (second in cost only to Senegal; see Tables and for details about grid electricity assumptions across countries). Due to increased reliance on coal and oil for electricity production (relative to Uganda), China, India, Senegal, and South Africa had higher median GHG emissions for grid-tied configurations ranging from 91.1 -98.6 kg CO2eq•cap -1 •yr -1 , while Uganda had significantly lower GHG emissions at 61.1 kg CO2eq•cap -1 •yr -1 .
