    Photovoltaic solar energy prediction using the seasonal-trend decomposition layer and ASOA optimized LSTM neural network model by Venkatachalam Mohanasundaram, Balamurugan Rangaswamy

    Published 2025-02-01
    “…Abstract As the global energy demand continues to produce, photovoltaic (PV) solar energy has emerged as a key Renewable Energy Source (RES) due to its sustainability and potential to reduce dependence on fossil fuels. However, accurate forecasting of Solar Energy (SE) output remains a significant challenge due to the inherent variability and intermittency of solar irradiance (SI), which is affected by factors such as weather conditions, geographic location, and seasonal patterns. …”

    Design of a Solar Powered Precision Irrigation System. by Othieno John Wangara

    Published 2023
    “…Flood irrigation wastes between 40 to 65 percent of the water due to factors like overtopping, runoff in the drain, rat holes in the canal bunds, evaporation from the water surface among others. [ 1] This is also accompanied by the fact that most used energy sources are fuel energy since hydro electrical energy (HEP) is not extended in most rural areas where actual agriculture is practiced and even the few rural areas having the hydroelectric power face frequent black outs thus leaving H.E.P unreliable thus fossil energy source the only alternative. These increase farming cost since the current irrigation systems use fuel energy and also have negative impacts on the environment through air, water and land pollution and its effects. …”
