This is being driven by a combination of the lack of electricity access to millions of people particularly in the African continent and the requirement for the reduction of environmental impact through the use of greener energy resources and systems. This paper summarizes an interdisciplinary research program investigating community energy systems in Ethiopia and Mozambique to facilitate energy transitions. Specifically, it compares community energy landscapes, progress made, and existing challenges and opportunities. To determine the status of community energy development in the two countries, recent publications and official policies were reviewed, and community energy managers were interviewed. The review showed that renewable energy sources are the dominant focus for community energy developments, which is key to achieving a cleaner energy future. However, progress in community energy development has been slow in these countries. There are several reasons that hinder community energy systems from driving the necessary energy transition to a cleaner, modern, and affordable energy. Some of these reasons are the absence of favorable regulatory frameworks, incentive package, knowledge on business models, weak commitments from stakeholders, and insufficient community involvement. These issues vary in degree between the two countries.","PeriodicalId":11825,"journal":{"name":"Energy Systems","volume":"342 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135475040","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For optimal performance at 17–21% PCE, certain factors need to be understood and addressed. This study estimates the solar PV potential of selected cities across Africa, using computational modelling. The selected sites’ cities are Abuja, Addis Ababa, Kinshasa, Pretoria, and Tripoli. Sites’ coordinate systems will be exploited to generate data from meteorological databases of the selected locations needed for the PV potential assessment. This information coupled with PV system configuration will be used as inputs for PV design and simulation. The PV potential of the selected location will be extracted from the resulting simulation reports in terms of irradiance, possible power output generation, performance ratio (PR) and capacity factor (CF). The study results and analysis as extracted from the reports of the modelled hypothetical 10-kWhp c-Si rooftop PV systems at the selected sited locations, show that—Pretoria possesses the highest GTI (2234.4 kWh/m 2 ) and the lowest GTI (1766.7 kWh/m 2 ) was observed in Kinshasa; Pretoria has the highest PV power output (PVOUT) (17.292 MWh/), and the least (13.678 MWh) in Kinshasa; the highest PR (77.4%) was observed in Kinshasa and Pretoria and the lowest PR (76.4%) in Tripoli; Pretoria and Kinshasa recorded the highest CF (19.7%) and lowest CF (15.6%), respectively. The results indicate that the examined locations are technically viable for the PV system schemes, and therefore, massive deployment of this technology in these areas is advised.","PeriodicalId":11825,"journal":{"name":"Energy Systems","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136112327","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
