A Methodology for Buildings Access to Solar Radiation in Sustainable Cities
Fernández-Ahumada, Luis Manuel; Ramírez Faz, José; López Luque, Rafael; Márquez García, Álvaro; Varo-Martínez, Marta (MDPI, 2019)The growing need to improve the environmental and energy sustainability of buildings involves the use of solar radiation incident on their surfaces. However, in cities, this task is complicated due to the constructive ... -
A novel backtracking approach for two-axis solar PV tracking plants
Fernández-Ahumada, Luis Manuel; Ramírez Faz, José; López Luque, Rafael; Varo-Martínez, Marta; Moreno-García, Isabel; Casares de la Torre, Francisco José (Elsevier, 2020)Solar tracking is a technique required to increase energy production in multiple photovoltaic (PV) facilities. In these plants, during low-elevation solar angle hours, shadows appear between the collectors causing a dramatic ... -
Analysis of the Influence of Terrain Orientation on the Design of PV Facilities with Single-Axis Trackers
Gómez Uceda, Francisco J.; Moreno-García, Isabel; Jiménez-Martínez, José M.; López Luque, Rafael; Fernández-Ahumada, Luis Manuel (MDPI, 2020)This paper investigates how to optimally orient the photovoltaic solar trackers of an axis parallel to the terrain, applying the sky model of Hay–Davies. This problem has been widely studied. However, the number of studies ... -
Benchmarking Analysis of the Panorama of Grid-Connected PV Installations in Spain
Gómez Uceda, Francisco J.; Varo-Martínez, Marta; Ramírez Faz, José; López Luque, Rafael; Fernández-Ahumada, Luis Manuel (MDPI, 2022)Renewable energies play an important role as a solution to the challenge of satisfying the growing global energy demand without jeopardizing the achievements in the fight against climate change. Given this panorama, different ... -
Design and 3D Manufacturing of an Improved Heliostatic Illuminator
Varo-Martínez, Marta; Ramírez Faz, José; López-Sánchez, Jesús; Torres Roldán, Manuel; Fernández-Ahumada, Luis Manuel; López Luque, Rafael (MDPI, 2022)Increasing daylighting levels contributes to improving the energy efficiency of buildings and consequently to the fight against climate change. This work presents a new illuminator based on a previous single-axis polar ... -
New Omnidirectional Sensor Based on Open-Source Software and Hardware for Tracking and Backtracking of Dual-Axis Solar Trackers in Photovoltaic Plants
Gómez Uceda, Francisco J.; Ramírez Faz, José; Varo-Martínez, Marta; Fernández-Ahumada, Luis Manuel (MDPI, 2021)In this work, an omnidirectional sensor that enables identification of the direction of the celestial sphere with maximum solar irradiance is presented. The sensor, based on instantaneous measurements, functions as a ... -
Proposal for the Design of Monitoring and Operating Irrigation Networks Based on IoT, Cloud Computing and Free Hardware Technologies
Fernández-Ahumada, Luis Manuel; Ramírez Faz, José; Torres Romero, Marcos; López Luque, Rafael (MDPI, 2019)In recent decades, considerable efforts have been devoted to process automation in agriculture. Regarding irrigation systems, this demand has found several difficulties, including the lack of communication networks and the ... -
Simulation of Self-Consumption Photovoltaic Installations: Profitability Thresholds
Varo-Martínez, Marta; Fernández-Ahumada, Luis Manuel; López Luque, Rafael; Ramírez Faz, José (MDPI, 2021)PV self-consumption can contribute positively to the spread of PV and, therefore, to the progress of renewable energies as a key element in a decarbonized energy model. However, the policies of each country regarding the ... -
Use of Polar Heliostats to Improve Levels of Natural Lighting inside Buildings with Little Access to Sunlight
Fernández-Ahumada, Luis Manuel; Osuna-Mérida, Maximiliano; López-Sánchez, Jesús; Gómez Uceda, Francisco J.; López Luque, Rafael; Varo-Martínez, Marta (MDPI, 2022)The growing need to increase environmental and energy sustainability in buildings (housing, offices, warehouses, etc.) requires the use of solar radiation as a renewable source of energy that can help to lower carbon ...
