تقدير الإشعاع الشمسي المباشر بمنخفض الجغبوب شمال شرق ليبيا ودوره في استدامة موارد الطاقة

Abstract

This paper discussed estimating solar radiation in the Jaghbub depression in northeastern Libya, and the study relied on estimating solar radiation rates for the years (2023, 2024, 2025, 2026, 2027). The study aimed to identify locations that benefit from the use of solar energy, using information systems techniques. Geography, selecting and determining the locations of stations according to fixed standards by building spatial suitability models to reach a budget through which these locations are determined. Several approaches and methods were relied upon for the study, including the regional approach, the spatial analysis approach, the quantitative analytical method, and the statistical method, in addition to The multiple criteria method, and one of the most important results reached is that the estimated average amount of solar radiation for the summer months of 2023 ranged from (301899-358399) kWh/m², and the estimated average amount of solar radiation for the summer months of 2024 was estimated at a value that ranged from (208724). - 249,945) kilowatt-hours/m². The estimated average amount of solar radiation for the summer months of 2025 was estimated at a value ranging from (428,511 - 507,067) kilowatt-hours/m², and accordingly, several suitable locations were proposed for establishing solar energy catchments.
