11.1
Solar Panels
CAUTION
Never attempt to work on solar array in wet or damp conditions.
Electrical current is always present.
Solar panels can produce an electrical shock or burn unless care is taken.
Solar panels are a live electrical power source. Current and power increase with light
intensity. Panels continue to produce nearly full voltage even in overcast conditions.
They produce DC voltage even when not connected to an electrical circuit.
Solar panels have no ON/OFF switch. Before commencing any maintenance on the
electrical connections on the unit
disconnect power supply at junction boxes
disconnect red solar regulator lead
NOTE
Even when you have taken every precaution, be aware that the solar panels
continue to generate current.
11.2
Orientation and Tilt
Correct orientation and tilt (angle to horizon) of the solar array is most important.
For
optimum power generation,
solar panels need to face the midday sun at an angle
roughly equal to the latitude of your location.
The rotation mechanism and pivoting jack enable you to orient and tilt the solar array.
Proper Orientation and Tilt Procedure
1.
Release the solar panel handbrake (upward thrust) and make sure solar cable is out
of the way
2.
Pull down and turn handle on the pivoting jack until panels are facing up into the sky
at approximately 45°
or the angle
that you require
3.
Using the handles above the panel brake, turn the solar array and orient it toward the
South (in southern hemisphere, towards North)
4.
Pull down on panel brake and lock the panels into position
At the same time, make sure the metal L clamp is gripping the rotation plate firmly
5.
Tighten the adjustment screw (use Phillips head screwdriver) if the panel brake
appears loose
To prepare the solar array for transportation, reverse the procedure.
Make sure you turn the panels in the opposite direction so that the power cable does
not become tangled in the rotate and tilt mechanism.
