5.13.1 Replacement Solar Panel
Electrical current is always present.
Solar panels can produce an electrical shock or burn unless sufficient care is
taken.
If you suspect a problem with the solar panel itself, test the panel output using a multimeter.
Before testing you must make sure of the following:
 The panel is in full sunlight.
 The controller module is OFF.
 The solar regulator is OFF.
Replacement solar panels must be the same wattage and ideally, from the same
manufacturer as initially installed in Ver-Mac’s factory.
