3 cards from this section. Quick, good the night before a test.
Define Global Horizontal Irradiance.
Think about total solar energy that reaches a flat surface.
What does the term Albedo refer to?
It affects radiation measurements and overall solar energy capture.
What does GHI stand for?
Think about the role of the sun with respect to a flat surface.
True or False: The Angstrom-Prescott Model directly measures irradiance.
Recall the focus of the model on sunshine duration.
A city has an annual average sunshine duration of 3000 hours. Using the Angstrom-Prescott model, estimate the expected GHI assuming a linear correlation of 0.8 with sunshine duration.
Multiply the correlation coefficient with the total sunshine hours.
Two solar panels are mounted at different tilt angles, 30 degrees and 45 degrees. Calculate the GTI considering they receive 500 Wh/m² of diffuse irradiance and 200 Wh/m² of direct irradiance, where the albedo effect is negligible.
Use the direct and diffuse values directly for this calculation.
