2.12. Adjusting the Optional Solar Panel
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.
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.

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-March 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
