  • IrradianceNet: Spatiotemporal deep learning model for satellite-derived . . .
    Solar irradiance forecasting can be traced all the way back to the late 19th century when numerical weather prediction models (NWP) were first developed (Yang et al , 2018) Since then, numerous methods have been developed to improve forecast horizons spanning from very short-term forecasts to multiple days ahead (Lorenz et al , 2009)
  • Direct normal irradiance related definitions and applications: The . . .
    Historically, the interest in accurate measurement of DNI started decades ago Early studies (e g , Linke, 1931, Linke and Ulmitz, 1940) identified the difficulty of separating the measurement of DNI from that of the diffuse irradiance in the immediate vicinity of the sun, hereafter referred to as circumsolar irradiance
  • Benchmark of estimated solar irradiance data at high latitude locations
    As irradiance estimates are more uncertain in cloudy conditions, the low clearness indices and high latitudes illustrates the challenges with estimating irradiance in Norway Challenges related to snow and horizon shading is also discussed, where the latter is especially pronounced in the rugged fjord terrain of Western Norway
  • Monitoring solar irradiance and PV module performance in mobile . . .
    Daily irradiance profiles of all irradiance sensors on the vehicle and the DHI and GHI from the roof of the ULFE building on the March 13, 2024 Vehicle states are denoted in the top row together with the acquired energy from the mobile PV module The numbers in circles represent different events, denoted also in Fig 12, and explained in the text
  • Solar Irradiance - an overview | ScienceDirect Topics
    The irradiance at earth's surface is lower than that at the top of atmosphere due to light scattering and absorption by certain gas molecules (N 2, O 2, H 2 O, CO 2, etc ) It is estimated that the globally averaged solar irradiance is approximately 1 365 kW per square meter in a 24-h day throughout a whole year [39]
  • Modeling daylight availability and irradiance components from direct . . .
    Modeling daylight availability and irradiance components from direct and global irradiance 281 3 2 Diffuse irradiance and illuminance on tilted "~ r surJaces modeling These models estimate the total (integrated) sky diffuse irradiance illuminance received by a surface ~~ = tilted from the horizontal (e g , a window)
  • Solar irradiance and temperature influence on the photovoltaic cell . . .
    Thereafter, an experimental validation is carried out by using real hourly values of titled irradiance G, cell temperature T and DC output powers (P DC), recorded from 01 12 2017 to 23 12 2017 for a total of 529 samples, of two PV plants located in different climatic zones Mediterranean (Brindisi, Italy) and Semi-continental (Meknes, Morocco
  • Deep learning models for solar irradiance forecasting: A comprehensive . . .
    The accurate forecasting of solar irradiance is of utmost importance for the power system designers and grid operators for efficient management of solar energy systems The intermittent and non-stationary nature of solar irradiance makes many existing statistical and machine learning approaches less competent in providing accurate predictions
  • Long-term changes in solar activity and irradiance
    The total solar irradiance (TSI) is the spectrally integrated radiative energy flux incident on the top of the Earth’s atmosphere at the mean Sun–Earth distance of 1 a u , and it describes the total radiative energy of the Sun received by Earth’s system
