The grid electricity could not reach many areas due to inaccessibly related to remoteness. Solar energy, a resource widely available throughout the country, is also not utilized. Accordingly, this study tries to identify limits on technical and social benefits of solar photovoltaic technologies in Ethiopia thereby its use to increase electricity access. Thus we assess factors affecting the dissemination activities, such as solar PV installation practices, Solar Home and institutional system distribution strategies, system failures and their causes. To conduct this research, we performed desk reviews, Key informant interview, focus group discussions and field surveys. In addition, we analyzed the impact of PV orientation by comparing simulation result made by PVsyst software at various angles observed during field survey. One Kebles from each four regions, namely SNNPR, Amhara, Oromia and Tigrai regions were selected, where about 20 households were surveyed. In doing so, Factors affecting the dissemination activities as well as best orientation were able to be determined. The study also assess that, how Availability of replacement and maintenance, lack of Public awareness creation and institutional problems, tariff and shortage of market can affect the accessibility and large scale distribution of PV system. In order to disseminate the solar PV in ample amount throughout the country, this study would like to recommend that factors affecting the distribution needs to be considered at all levels in way to achieve maximum result, technical capability of the solar PV needs to optimized through appropriate installation with a recommended tilt and azimuth angle. By doing so, the vision that we aspire to have sustainable energy supply in the country as well as a reduce level of emission from biomass will be garnered.
