Factors that Influence the Adoption of Solar Home Systems in Rural Areas in Uganda: A Case Study of Karamoja Region
Abstract
Evidence to date suggest that electrification is linked to a wide range of improvements,
including more income generating activities (Khandker et al. (2012,2013)), generator of female
employment generation (Dinkelman (2011); Grogan and Sandanand (2013)), better
productivity (Kirundi et al. (2009)), firm creation and industrial development (Peters et al.
(2011); Rud (2012)), higher literacy rate (Kanagawa and Nakata (2008)), and increased study
time and educational performance (Gustavsson (2007); khandker et al. (2012); Furukawa
(2014)). Globally, annual production capacity has increased from 1 to 40 GWp over the last 2
decades, and the sector has experienced annual growth-rates of 40-60 % (REN21 2013; Jäger-
Waldau 2013) in the past five years. This is mainly due to a combination of economies of scale
and market development in selected countries in Europe (Germany, Italy and Spain), China
and the US created by favourable framework conditions, such as feed-in tariffs. In the period
from 2008 to 2013 this led to a decrease of 60% in residential system prices in the most
competitive markets and a decrease in module prices of 80% (Jäger-Waldau 2013). Although,
an estimated 1.6 billion people in the developing world have no access to electricity [Saghir,
2005] with Sub Saharan Africa accounting for 37%. According to the International Energy
Agency (IEA). The vast majority of these people live in rural areas of developing countries,
where scarce of government investment and difficult geography keep the national electric grid
from extending to their villages. Investment in transmission lines is expensive, especially when
a village is far away from a large city or in the mountains (Steve Dahlke, 2011). In 2009, 91%
of rural population in sub-Saharan Africa had no access to electricity; families could spend up
to 25% of their household revenue on costly yet unsafe lighting sources like kerosene, candles
and battery lights (IEA, 2011). The reliance has locked families in a vicious cycle of poverty;
draining not only their income but also having a detrimental effect on their health. They also
cause fatal burns, fires and emit carbon which has tremendously contributed to climate change.
Uganda, despite efforts by governments and international donor agencies toward sustainable
energy for all (United Nations (2010)), Universal access to electricity has been challenging.
The government, in conjunction with multilateral agencies, does invest in increased energy
2
production and grid expansion within the country. The ultimate goal of Uganda’s National
Development Plan and Uganda’s Vision 2040 is to meet the energy needs of the Ugandan
population for social and economic development in an environmentally sustainable manner.
However, with population growth rates among the highest in Africa (estimated at 3.5% for
2012) and minimal available infrastructure, the level of investment is not substantial enough to
meet need (David Nicholson and Kim Beever, 2012). This has resulted in the use of solar
energy (Kivaisi 2000), wind energy (Henderson, et al. 2009), 450 Tong et al. Perspectives on
Global Development and Technology 14 (2015) 448-491 small hydro-power (Shrestha and
Bhattarai 1993; Egre and Milewski 2002), and biomass (Sirte, et al. 2008) in the provision of
clean alternative energy sources that could increase the access of the rural/urban poor to electric
power (Abdullah, et al. 2010). Uganda is situated near the equator, with high levels of solar
radiation; the average solar radiation is 4.8 kWh/m2/day (Bbumba 1999). Governments can
encourage alternative state and non-state entities to venture into power generation through a
“feed-in tariffs” mechanism for every registered renewable energy power plant (Dusko and
Marinela 2010). Uganda is already exploring this approach, which has been successfully
applied elsewhere. This transition has been facilitated to varying degrees by conducive
enabling frameworks comprising innovative financing schemes, exemptions from VAT and
import taxes, standardized power-purchasing agreements and feed-in tariffs. Masa (2010),
assessing two models of solar home systems (SHS) on a selection of variables, argues that the
success of a particular technology hinges on the projects’ conformity with the institutional
development in the country.
