In the present paper, it is carried out the design of a photovoltaic installation connected to the utility grid with panels mounted on a floating structure at an irrigator's community. The objective is to determine the technical and economic feasibility of a floating photovoltaic installation to partially or totally cover the energy demand. The flo...

Más reciente es la aportación al 2020 Global Congresson Electrical Engineering (GC-ElecEng), dedicada al diseño de un sistema de energía solar fotovoltaica aplicado a otra comunidad de regantes de la Comunidad Valenciana, con el objetivo de determinar la viabilidad técnica y económica de una instalación fotovoltaica flotante para cubrir total o parcialmente su demanda energética (Vargas-Salgado et al., 2020). ...
La implantación y desarrollo de centrales de energía solar fotovoltaica flotante en España ha sido posible gracias a las políticas de fomento de las energías renovables de la Unión Europea, la disponibilidad de abundante radiación solar y la existencia de numerosos embalses, consecuencia de la política hidráulica de los años 60. En la actualidad se vive una etapa de desarrollo, consecuencia de la nueva apuesta por las energías renovables para cumplir con las directrices comunitarias. Los Planes de Energías Renovables y las medidas de apoyo a esta tecnología por parte del Gobierno de España están contribuyendo a su crecimiento. Este trabajo tiene como objetivo realizar un análisis de la implantación de la energía solar fotovoltaica flotante en España. El método utilizado se ha centrado en el estudio del papel de la universidad en la investigación de este tema, las publicaciones y la difusión del conocimiento sobre este tipo de instalaciones; de las normativas europea, española y regional en relación con este sector energético; así como de las empresas españolas fabricantes de esta tecnología; las instalaciones existentes, y la planta solar fotovoltaica flotante “Sierra Brava” como estudio de caso. Los resultados confirman la clara relación entre la política de incentivos y su expansión, que viene motivada por el progreso tecnológico.
... It has a payback period of 15 years which is long time as compared with 7-10 years of money return period for PV systems in Spain. This grid connected FPV system is proved to save around 13.55% of the annual energy formerly supplied from the grid [16]. ...
The demand for electricity has increased rapidly in Ethiopia. Renewable energy sources such as solar PV are being used to respond
to the power demand and cover a small percentage of the country’s energy need. However, in Ethiopia, where the majority of the
land is utilized for agriculture, the land required to generate solar PV power in a large scale is a significant barrier. Big dams, such
as Great Ethiopia’s Renaissance Dam, can be used for a solar floating system to eliminate the need for land and transmission
infrastructure. Due to its wider area covered by the reservoir, which is about 1,874,000,000 m2
, the potential of the renaissance
dam needs to be investigated for solar PV floating installation to meet the electricity demand in residential, commercial, and
industrial sectors in Ethiopia. In addition, the cooling action of the water on the PV floating allows it to keep its efficiency and
increase the power output from the panels. In this study, the performance of grid-connected floating PV systems was evaluated
in terms of power generation potential, performance ratio, capacity utilization factor, greenhouse gas emissions, and water
conservation. The power consumption of peoples living in the GERD generation site is nearly 1 MW. Though they get
electricity through the grid, this study considers performance assessment of a 1 MW solar FPV with the intention of covering
the energy need of the hydropower station itself and near rural communities. Modeling and simulation of the proposed FPV
plant is done with the help of PVsyst software tool. Finally, the analysis reveals that the GERD has the FPV capability to
generate 18,740 MW of maximum power, and its performance was assessed for a 1 MW grid-connected FPV system. The
benefits of employing FPV in energy production, water conservation, CO2 emission reduction, and economic benefit are
demonstrated in this study. Furthermore, the installation of 1 MW FPV saves 54.4 million liters of GERD water from
evaporation per year, which benefits the Blue Nile’s downstream countries to conserve their share of water.
... Vargas-Salgado et al. [23] emphasize that the use of FPV in irrigator pools is an attractive alternative. The authors project an FPV installation, in one of these pools, connected to the utility's network to meet the energy demand of an irrigator's community in Spain. ...
Brazil has high solar potential. The yearly sum of solar irradiation is approximately 1924.07 kWh/m², therefore, harnessing this potential is promising. The country is dependent on hydroelectric plants, however, increasingly frequent droughts have severely affected hydrogeneration. The installation of floating photovoltaic (FPV) systems in existing hydropower reservoirs, would provide additional electricity to help compensate hydropower production during dry periods and reduce evaporation losses while helping to sustainably meet Brazil's electricity demand. This study provide an analysis of FPV potential in Brazil's region, named the Tocantins-Araguaia Basin, by using water surface data from 30 hydropower reservoirs. In addition to the new electricity production, evaporation savings and its extra potential hydroelectricity were also estimated. A survey of the reduction in CO2 emissions was conducted, given that the complementary electricity to hydroelectric plants would be through solar generation, thus avoiding the activation of thermoelectric plants. The main results indicate the high FPV potential, corresponding to an electricity production that varies from 25.04 to 2555.04 TWh/year, and a range of 19.86–2024.30 million tCO2/year of avoided emissions. Regarding the potential arising from the evaporation water savings, the values vary between 16.17-892.95 GWh/year.
