EXPLOSION HAZARD: Ensure the area in which you perform this operation is non-hazardous.
Performing this operation in a hazardous area could result in an explosion.
The mounting brackets allow you to adjust the solar panel for maximum solar exposure. You can
adjust the swivel of the panel by adjusting the U-bolt.
Figure 2-27: Adjusting Solar Panel Tilt Angle
▪
Point the solar panel surface due south (in the northern hemisphere) or due north (in the
southern hemisphere) at an angle determined by the latitude of the site. Table 2-6 shows the
angle (from horizontal) at which you should install the solar panel to maximize annual energy
output. At most latitudes, you can improve performance by reducing the angle during the
summer and increasing the angle during the winter. If no seasonal adjustments in panel
direction are needed then adjust the position for the worst-case December-January angle.
▪
Solar insolation is the amount of solar energy in hours received each day by an optimally
tilted panel during the worst month of the year. An insolation rating of one hour means that
the site, on average, would receive one hour of solar energy at the panel's rated power level
(1000W/m
2
per day). This rating varies from less than one hour in northern Canada to more
than six hours in the Sahara Desert.
