Photovoltaic Flashcards
Greater solar irradiance means energy accumulates faster, which results in greater solar irradiation.
True or False
True
Name the two major types of radiation the ground
- Direct
2. Diffuse
____radiation is radiation that is scattered by the atmosphere and clouds.
Diffuse
Air mass depends on…
- Time of day
- Time of year
3 .altitude - Latitude
____is usually used to rate the solar energy potential of a location by calculating the average energy received per day.
Insolation
Direct solar radiation is measured with a ____
Pyreheliometer
____time is a timescale based on the apparent motion of the sun crossing a local meridian.
Solar
Solar___is the intensity of solar power.
Irradiance
Solar____is the total amount of solar energy accumulated on an area over time.
Irradiation
____radiation is all of the solar radiation reaching Earth’s surface and is the sum of direct and diffuse radiation.
Total Global
____is the point in the sky directly overhead a particular location.
Zenith
A____is a sensor that measures the total global solar irradiance in a hemispherical field of view.
Pyranometer
A____is Earth’s orbital position when solar declination is at its minimum or maximum.
Solstice
The solar\_\_\_angle is the vertical angle between the sun and the horizon. A.altitude B.azimuth C.declination D.elevation
A. Altitude
___radiation is just outside of Earth’s atmosphere
A. Extraterrestrial
Solar\_\_\_is the angle between the equatorial plane and the line joining the centers of the sun and Earth in the ecliptic plane. A. Declination B. Generation time C. Noon D. Time of day
A.declination
___is a representation of the relative thickness of atmosphere that solar radiation must travel through to reach Earth’s surface.
Air mass
___solar radiation is solar radiation that reaches the surface of earth.
Terrestrial
___is the solar irradiation received on a specified surface over a period of time. Typically one day.
Insolation
The atmospheric has___plays an important role in blocking harmful ultraviolet radiation from reaching Earth’s surface
Ozone
A\_\_\_cell is an encapsulated PV cell that outputs a known amount of electrical current per unit of solar irradiance. A. Inverter B. Module C.PV array D. Reference
D. Reference
A___is a plane formed by a due- South longitudinal line through a location on earth and projected out into space.
Meridian
The solar___is the area of sky between sun paths at summer solstice and winter solstice for a particular location.
