Energy-Economic-Environmental Analysis of On-Grid Solar System for Electricity and Hydrogen Production at Homemade Scale: Effect of Different Shades

International Transactions on Electrical Energy Systems, Journal Year: 2023, Volume and Issue: 2023, P. 1 - 18

Published: March 28, 2023

As an energy source, solar cells can be central to peak load control in different power companies. Hydrogen production cost-effective if the generated electricity is unusable. Shades reduce cell current and fundamentally alter panel function, making it necessary restore panels optimum generation. Owing issues outlined this paper, energy-economic-environmental effect of a shade detection algorithm was examined for scenarios, domestic-scale hydrogen evaluated. partial on amount has not been investigated quantitatively so far, issue discussed study. The laboratory equipment developed by authors were used detect shadow. Thanks respected reviewer, following sentence added abstract. analyses HOMER V2.81 software 20-year average data residential building city Tehran obtained from NASA website. results recommended that designed increases scenarios between 5.8% 32.9%. also revealed significantly lessen pollutants 100 kg/year 240 kg/year.

Design and implementation of smart integrated hybrid Solar-Darrieus wind turbine system for in-house power generation

Renewable Energy and Environmental Sustainability, Journal Year: 2024, Volume and Issue: 9, P. 2 - 2

Published: Jan. 1, 2024

This paper presents the design and development of an integrated hybrid Solar-Darrieus wind turbine system for renewable power generation. The Darrieus turbine's performance is meticulously assessed using SG6043 airfoil, determined through Q-blade simulation, validated via comprehensive CFD simulations. study identifies as optimal surpassing alternatives. simulations yield specific coefficients (0.2366) moment (0.0288). also introduces a prototype, showcasing 10 W photovoltaic module improved with airfoil. focus extends to optimized PV solar-wind seamlessly IoT technology remote monitoring. Addressing weather challenges, research suggests blade shape optimizations IoT-based solution leveraging ESP32 Wi-Fi module. Theoretical results project electrical energy generation ranging from 0.88 kW on March 14, 2023, 0.06 February 20, 2023. turbines, experiencing increased drag, require less lift operate. Experimental theoretical converge well, affirming model's reasonable assumptions. Beyond advancing technologies, this sets stage future investigations aimed at enhancing efficiency capabilities wind-solar systems.
