Despite the abundance of renewable energy resources in the country, the rural and urbanrncommunities in Ethiopia are suffering from shortage of electricity. The grid electricity could notrnreach many areas due to inaccessibly related to remoteness. Solar energy, a resource widelyrnavailable throughout the country, is also not utilized. Accordingly, this study tries to identifyrnlimits on technical and social benefits of solar photovoltaic technologies in Ethiopia thereby itsrnuse to increase electricity access. Thus we assess factors affecting the dissemination activities,rnsuch as solar PV installation practices, Solar Home and institutional system distributionrnstrategies, system failures and their causes. To conduct this research, we performed deskrnreviews, Key informant interview, focus group discussions and field surveys. In addition, wernanalyzed the impact of PV orientation by comparing simulation result made by PVsyst softwarernat various angles observed during field survey. One Kebles from each four regions, namelyrnSNNPR, Amhara, Oromia and Tigrai regions were selected, where about 20 households werernsurveyed. In doing so, Factors affecting the dissemination activities as well as best orientationrnwere able to be determined. The study also assess that, how Availability of replacement andrnmaintenance, lack of Public awareness creation and institutional problems, tariff and shortagernof market can affect the accessibility and large scale distribution of PV system.rnIn order to disseminate the solar PV in ample amount throughout the country, this study wouldrnlike to recommend that factors affecting the distribution needs to be considered at all levels inrnway to achieve maximum result, technical capability of the solar PV needs to optimized throughrnappropriate installation with a recommended tilt and azimuth angle. By doing so, the vision thatrnwe aspire to have sustainable energy supply in the country as well as a reduce level of emissionrnfrom biomass will be garnered.rnKey Words: SHS and institutional PV systems, social benefit, factors affecting solar PVrndissemination, orientation optimization, tilt angle and azimuth angle, modeling.
