DANGER
EXPLOSION HAZARD: Never remove end cap(s) in a hazardous location. Removing end cap(s) in a
hazardous location could result in an explosion.
▪
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 2-8
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
