Irradiance is a measure of how much solar power is striking a specific location.
True
False
Solar radiation data is used to size and estimate the performance of a PV system.
True
False
As a general rule, a PV array should be free of shade from 9:00 pm to 3:00 am.
True
False
The profile angle is the projection of the altitude angle onto an imaginary plane that is perpendicular to the surface of an obstruction.
True
False
____________________ is the solar irradiation received over a period of time, typically one day.
Insolation.
Photosynthesis.
Evaporation.
Condensation.
Solar ____________________ is a measure of the total amount of solar energy accumulated on an area over a period of time.

The Solar Pathfinder™ and the Solmetric SunEye™ are examples of solar site ________________ devices.
selector
analyzer
calculator
monitor
Solar site selector devices work by comparing the solar (a) for a specific location to an image of the different shading obstructions around the proposed array site.
The solar constant value on the surface of the earth at sea level at solar noon is:
1361 W/m²
1000 W/m²
1500 W/m²
2000 W/m²
The sun’s altitude is measured in the number of above the horizon.
(a)
How does a PV cell receive the highest average insolation?
have a tilt angle equal to its latitude
By being shaded by trees
By being placed indoors
By being covered with dust
How would a digital camera and digital voice recorder be used during a site inspection visit?
To capture visual and audio evidence
To communicate with the team
To navigate the site
To measure distances
Knowing the solar window for a given PV cell installation location is important because:
it determines the optimal angle for solar panels.
it affects the color of the solar panels.
it changes the type of solar panels needed.
it influences the warranty period of the solar panels.
In what two ways can an array performance calculation be made?
calculations can be made by hand or with a computer program.
By measuring execution time and memory usage
Through algorithm optimization and data structure selection
Using benchmarking and profiling tools
What must you attach to a protractor to use it to measure altitude angle?
A plumb line(string with a weight)
A ruler
A compass
A pencil
Write the formula used to calculate the minimum distance between rows of PV modules.
(a)
