The purpose of this study is to find the most profitable way construct a photovoltaic (PV) system on residential building in Amman by taking into account local climate, average monthly energy use, and rates charged electric utility. has usage 550 kWh average, with biggest demand for occurring months January December lowest April, May, June. mounted at variety angles, including 10°, 20°, 32°, 54°. This took fact that price electrical dependent electricity order determine periods day when there greatest need energy. Another crucial aspect consider sun's strength, which shifts during course year. When solar intensity its peak power are their highest, PV considered as realistic choice satisfy needs. because systems can generate even cloudy conditions. A comprehensive examination taken cell produced result also included study.

Solar energy with hydropower power plants marks a significant leap forward in renewable innovation. The combination ensures consistent supply by merging the fluctuations of solar predictable storage provided hydropower. This research aims to predict high irradiance on maximize active generation. A novel hybrid decomposed residual ensembling model for deep learning (SBL TSR R W) using models such as autoregressive integrated moving average (ARIMA) and seasonal‐trend decomposition loess (STL) along prediction optimization Bidirectional LSTM (Bi‐LSTM), Whale Optimization Algorithm (WOA) methods are used irradiances. Various forecasting methods, including STL‐Bi‐LSTM, SBL TS , T RS models, assessed determine their effectiveness predicting radiation. results show accuracy proposed model, RMSE MAE values 1.85 W/m 2 1.31 respectively. W more accurate than Bi‐LSTM, value reductions 517%, 217%, 151%, 98%, 1%,

Conventional blower-type open-circuit open-jet wind tunnels use a blower, wide-angle diffuser, settling chamber, screens, honeycomb, contracting nozzle, test section, and exit diffuser to develop uniform, plug shaped velocity profile, inside the test-section. In current study, hypothetical design of low-cost simple tunnel has been proposed produce similar flow characteristics but by using fewer components viz. inlet duct, plenum collector, which is novelty design. The basis hypothesis obtain fully developed at moving belt-type lid-driven cavity create low-speed movable membrane boundary main jet, cessation free jet expansion significant amount section. new validated through numerical experimental results as well mathematical modelling. values ratio standard deviation average normalized are found in range 10−2 for 50% blockage cross-section. Curve fitting with profile equation showed close resemblance. Experiments performed on Savonius rotor modified compared classic obtained conventional tunnel. RMS error between both contained 10−1 10−2. All validations proved aptness innovative testing. presented first its kind generates desired characteristics.

ABSTRACT The increasing global energy demand driven by climate change, technological advancements, and population growth necessitates the development of sustainable solutions. This research investigates design, modeling, simulation a 2.5 MW solar‐wind hybrid renewable system (SWH‐RES) optimized for domestic grid applications. A survey conducted across 450 households identified total 2.3 MW, with distinct day night usage profiles. In response, consisting 1.5 solar park 1 wind unit was designed to ensure continuous power supply. modeled simulated using MATLAB, its performance evaluated through detailed Total Harmonic Distortion (THD) analysis. addresses critical need high‐quality supply designing, simulating meet surveyed load, while also reducing THD acceptable levels improved quality stability. results demonstrated significant reduction in THD, voltage decreasing from 45.48% 26.20% current 8.32% 2.88% after implementing filtering components. These findings underscore effectiveness proposed SWH‐RES providing stable, addressing growing
