Several technical factors characterise rooftop solar projects informing the decision to go solar. Amongst these factors are the solar energy available from the PV system, self-consumption ratio and overall system efficiency. However, from the investor's viewpoint, the most critical factor is the economic viability of the proposed project. Since energy economics is vital to investors, the paper seeks to analyse the economics (financial feasibility and profitability) associated with different types of prosumers in Ghana's residential and commercial classes. The net present value, internal rate of return, profitability index, and discounted payback were the economic indicators used to appraise Ghana's financial feasibility and profitability of electricity prosumption. The study shows that electricity prosumption in Ghana is worth investing in. The best investment option in the residential and commercial classes is the prosumers with grid integration and without storage (type 2). In the residential tariff class, the best investment option is the prosumers, whose energy demands are between 301 kWh and 600 kWh.</p></div>","PeriodicalId":101173,"journal":{"name":"Solar Compass","volume":"5 ","pages":"Article 100035"},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50199379","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}

The analysis attempted to give better insight into the larger question of why more solar desalination plants are not being established by reviewing different technologies, drivers, barriers, and markets. Critical barriers which were dependent on the level of regional development were found to be uncertainty of government subsidies and a lack of regulatory policies. A new tool called a Pareto frontier may be utilized to generate optimal points in complex scenarios with a high number of variables. This all-inclusive method should be employed in any major decision-making process. Furthermore, in exciting innovative research studies, a sustainable Janus wood evaporator was developed that overcame many of the current solar desalination problems. While subsidies were crucial in the growth of renewable energy programs, barriers in deployment of solar desalination systems still exist such as low electricity tariff structures and fragmented energy policies. The overall trend was towards integration of renewable energy with conventional sources and energy storage systems.</p></div>","PeriodicalId":101173,"journal":{"name":"Solar Compass","volume":"5 ","pages":"Article 100034"},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50199377","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}

Data on the electric load was gathered for two schools and Panchayat Ghar. The PV/biogas hybrid configuration was designed utilizing the Hybrid Optimization Model for Electric Renewable (HOMER) and techno-economic analysis is carried out to fulfill the load requirements. The available biomass potential and the data on solar irradiance of the study area were utilized in the HOMER software to carry out the analysis. The HOMER analysis produced a solution that included total net present cost (NPC) and cost of electricity (COE), and these results were then further improved using sensitivity analysis. The sensitivity analysis employed sensitivity parameters like biomass potential, biomass pricing, solar irradiance, and variation in loads. Based on the NPC and COE, this analysis evaluates the system performance and demonstrates that it is techno-economically feasible.</p></div>","PeriodicalId":101173,"journal":{"name":"Solar Compass","volume":"3 ","pages":"Article 100031"},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772940022000248/pdfft?md5=a1465fb8a616fd9714dd4f5badc9ad1a&pid=1-s2.0-S2772940022000248-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"137055779","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
