Financing of Residential Rooftop Photovoltaic Projects Under a Net Metering Policy Framework: The Case of the Colombian Caribbean Region

The inclusion of photovoltaic energy in the Colombian energy matrix has had several difficulties due to the lack of energy policies and regulations in renewable energy projects. The lack of government support with subsidies that extend the coverage of PV energy projects in residential areas has made the collection of funds more challenging. This paper presents a techno-economic analysis for the implementation of grid-connected photovoltaic projects on the roofs of residential areas, under the net metering policy framework. For the profitability analysis, the discounted cash flow (DCF) method was used. The revenues were obtained from the forecasts of the electrical power production of the PV system, based on the characteristics of the Colombian Caribbean Region. For this purpose, the meteorological data (2013-2017) of this region were used as an input for the calculation of the economic benefits that can be achieved with the implementation of PV systems. Based on the technical sizing and economic assumptions, it was proved that the DCF method allows to accurately determine the optimal debt ratio. After evaluating the three scenarios proposed, it was demonstrated that profitability and self-sustainability, with investment from creditors, is obtained from the implementation of PV systems of at least 3 kWp

A Hybrid Energy Solution for the Sustainable Electricity Supply of an Irrigation System in a Rural Area of Zona Bananera, Colombia

A hybrid energy system allows the integration of various technologies to meet energy demands competitively. These systems are widely used in rural areas with connection problems in the conventional electrical grid due to their economic and environmental advantages. Thus, this paper presents the design and simulation of a hybrid energy system that evaluates the suitability of using various generation sources such as photovoltaic energy, biomass, diesel generation and connection to the conventional electrical grid, in order to establish scenarios competitive to supply energy in an irrigation system of the Palmar de la Sierra experimental field, located in the municipality of Zona Bananera, Magdalena, Colombia. The sizing of the system was performed with Homer Pro software, with which technical, economic and environmental aspects of the studied scenarios were evaluated. The data of solar irradiance and the characteristics of the oil palm fruit peel, used for generation with biomass, were provided by the Cenipalma company. The results obtained show that the hybrid system (photovoltaic, biomass, diesel) can satisfy the demand of 2200 kWh/day of the irrigation system under study, using a connection to the electricity grid that allows the purchase and sale of energy.Keywords: Hybrid Energy System, Photovoltaic Energy, Biomass Gasification, Financial AnalysisJEL Classifications: Q42, G32, G00, O13DOI: https://doi.org/10.32479/ijeep.11014</p
