Solar power plants are among the most widely used renewable energy sources today. Varying radiation levels from region to region, and similarly varying consumption depending on the user within a given region, make the optimal sizing of these plants challenging. In this study, a machine learning-based surrogate model f…

ABSTRACT Solar irradiance is considered a fundamental parameter for photovoltaic systems. Stations established worldwide to measure solar irradiance are limited in terms of coverage. Therefore, many solar irradiance prediction models and techniques are being developed to obtain solar irradiance data. The influence of…

Accurate forecasting of photovoltaic (PV) power generation is essential for the reliability and cost-effectiveness of renewable-based power systems to be maintained. This study provides a comprehensive comparison of several statistical and machine learning approaches, including SARIMA, SVR, k-NN, RF, XGBoost, and LSTM…

Photovoltaic (PV) performance in desert environments is significantly hindered by soiling and partial shading. To bridge the gap in empirical data for extreme Saharan conditions, this study presents a novel techno-economic assessment of uniform horizontal shading (UHS) specifically conducted in Mauritania. Controlled…

The production performance of photovoltaic systems depends not only on historical data but also directly on complex environmental dynamics such as temperature, solar radiation, wind, and cloud cover. In this study, a unique dataset was created by integrating production records from the Yulara Solar system in Australia…

Bu çalışmada, günlük küresel güneş radyasyonunu tahmin etmek için çok ufuklu bir zaman serisi tahmin yaklaşımı geliştirilmiştir. Veri seti günlük frekansa göre hizalanmıştır ve eksik gözlemler, zamana dayalı enterpolasyon ve yılın gününe (DOY) dayalı mevsimsellik duyarlı istatistikleri birleştiren iki aşamalı bir atam…
