Long-term solar irradiance variability [PDF]

Symposium - International Astronomical Union, 1997
Measurements of the solar energy throughout the solar spectrum and understanding its variability provide important information about the physical processes and structural changes in the solar interior and in the solar atmosphere. Solar irradiance measurements (both bolometric and at various wavelengths) over the last two decades have demonstrated that ...

Mathematical model for predicting the performance of photovoltaic system with delayed solar irradiance

Kuwait Journal of Science
Photovoltaic systems convert solar irradiance into electricity. Due to some factors, the amount of solar irradiance arriving at the solar photovoltaic collector at a specific location varies. The goal of this study was to develop a mathematical model for

Experimental Assessment of the Meliss Simulation Model Accuracy of the Direct Solar Irradiance in Brasov, Romania

Annals of West University of Timisoara: Physics, 2018
The solar irradiance is the main input parameter when designing solar energy conversion systems. A poor accuracy of the solar irradiance simulation models negatively affect the output energy and the durability of the solar energy conversion system.

Solar irradiance variations

Eos, Transactions American Geophysical Union, 1983
The planned repair in orbit by NASA of the Solar Maximum Mission (SMM) in April 1984 provides an excellent opportunity for improved observations of the sun. In retrospect the solar‐terrestrial research community should have organized new programs before the 1980 launch of this satellite, but foresight is sometimes difficult to achieve.

New challenges in solar energy resource and forecasting in Greece

International Journal of Sustainable Energy, 2018
Aerosols and clouds are the most important constituents in the atmosphere that affect the incoming solar radiation, either directly through absorbing and scattering processes or indirectly by changing the optical properties and lifetime of clouds.
