5 cards from this section. Quick, good the night before a test.
What is direct solar radiation?
Think about sunlight you see directly on a clear day.
Define diffuse radiation.
Consider how light changes on a cloudy day.
What type of solar radiation is directly received without scattering?
Think of how sunlight comes straight to you on a sunny day.
True or False: Diffuse radiation can only occur on cloudy days.
Consider how sunlight behaves in different conditions.
A solar power plant receives 6 hours of direct sunlight per day and averages 4 hours of diffuse sunlight. How would you estimate the total global radiation that affects energy collection each day?
Remember to consider both direct and diffuse contributions.
If a surface with high albedo reflects 70% of incoming sunlight, calculate the impact of reflected radiation on overall energy capture in addition to direct sunlight.
Think about how much sunlight is utilized versus how much is reflected away.
