Résumé
Solar PV systems are suitable for areas where grid connections are unavailable. Northeastern Kenya, being an off grid area, requires an alternative energy source to close the gap of electricity shortages. This Study presents the development of an effective approach of designing, assessing, analyzing and determining economic viability of solar energy availability in Wajir town. Situated in the north-eastern part of Kenya with population of 0.7 million, the county receives about 300 sunny days in a year. The unique weather profile favors the adoption of the solar energy technology. Solar Radiation was recorded for three months (October, November and December 2016) and also from the meteorological headquarters from the year 2000 to 2010. Results revealed that Wajir has an average daily insolation of 6.6 kWh/m2. Energy demand survey of 20 households, 20 shops and the main hospital were conducted and later on design using Sunny Web design software was used to model by approximating 300 households, 20 shops and the main referral hospital. Sizing for PV array, inverters and modules were done to obtain 122.25 kWp system for households, 25 kWp system for shops and 239 kWp system for the hospital. Calculated costs for the households, shops and the hospital are US$ 164714, US$2315 and US$282873.7 respectively with payback period of the whole design being 6-7 years.
