Roof Azimuth Definition

It specifies how many degrees the surface of the thermal collector or photovoltaic module deviates from the exact south facing direction the azimuth angle depends on the geographical location of the observer the date time and time zone.

Roof azimuth definition.

The angle between the projected vector and a reference vector on the reference plane is called the azimuth. Set to flush mount to design a tilted residential roof. Steps for measuring roof azimuth. For example a 7 12 roof pitch means that for ever 12 of horizontal distance the roof will increase in height by 7.

An azimuth is an angular measurement in a spherical coordinate system. Definition the azimuth and tilt confirmation of solar panel is the one of important factors in the design of solar pv system. In terms of solar pv system the due south of azimuth is 0 it is minus angle from south to east to north it is positive angle from south to west to north. Azimuth is a horizontal angle measured clockwise in degrees from a reference direction usually the north or south point of the horizon to the point on the horizon intersected by the object s line of altitude a line from the observer s zenith through the object to the horizon.

Walls are considered vertical surfaces. The horizontal angular distance from a reference direction usually the northern point of the horizon to the point where a vertical circle through a celestial body intersects the horizon usually measured clockwise. A horizontal roof has an azimuth angle of 0 o and a tilt angle of 0 o. Align the base of the compass with the edge of the roof.

Enter the tilt of the roof. The roof azimuth angle is the azimuth angle of the equivalent wall. The roof azimuth tool is provided to you for free by solmetric. Knowing what direction a roof faces its azimuth is important to accurately estimate a roof mounted pv array s generation potential.

The azimuth is the angle of easy west south and north. The tilt angle can be 61 to 90 degrees ashrae std90 windows are glass on walls and doors. Right click the midpoint on the top or bottom edge of the roof to set automatically to align with the edge of the roof. Use linear keepouts for ridgeline setbacks.

For example increase the tilt angle until it is vertical and it is the orientation looking out from inside. They are assumed to have the same azimuth orientation angle as the wall it is located on. Most compasses will have an indicating arrow that will be perpendicular to the roof edge. When used as a celestial coordinate the azimuth is the horizontal direction of a star or other astronomical object in the sky.

With the use of a compass and magnetic declination a roof s orientation can be determined using these few simple steps. Use align to click to fine tune module layout. The star is the point of interest the reference plane is the local area around an observ. The vector from an observer to a point of interest is projected perpendicularly onto a reference plane.

Solmetric focuses on developing quality solar site assesment tools that provide capabilities such as solar access shade measurements pv design and simulation software and pv performance verification and iv curve measurements.
