Assumption
Length of solar module: 1.64m
Width of solar module: 0.992m
Inter-module gap: 0.01m
Length of site: 100m
Width of site: 25m
All sheds plane looking South with 10° tilt angle.
2 modules in up direction in each row.
Sun altitude is 23° at 09:00 h on December Solstice
Sun altitude is 63° at 13:00 h on December Solstice
Sun altitude is 28° at 17:00 h on December Solstice
Prerequisite
Prerequisite
Study about Step 3 Determine Collector Tilt Angles is reccomended
This article focuses on calculation on unlimited sheds, for one side fixed tilted calculation, refer to Step 2 Design PV array architecture.
Concept
Concept
D Distance between rows of PV modules (m)
L Row width (m)
β Tilt angle of PV array (°)
α Altitude of Sun at 9:00 h solar time.
Site location = Opposite of solar plane looking direction
For Nothern Hemisphere regions, use December Solstice.
For Southern Hemisphere regions, use June Solstice.
The sun location is the lowest during these Solstice.
W Width of PV array
Step 5.1 Landscape Orientation
Step 5.1 Landscape Orientation
Assumption state that all sheds plane looking South, means the site location at Nothern Hemisphere.
Step 5.2 Portrait Orientation
Step 5.2 Portrait Orientation
Assumption state that all sheds plane looking South, means the site location at Nothern Hemisphere.
Step 5.3 Decide Orientation
Step 5.3 Decide Orientation
Portrait orientation is selected because maximum number of solar modules is larger (990 modules)
