5.13 Solar Panel(s)
The solar panel generally requires little maintenance apart from thorough cleaning. Lack of
solar panel maintenance eventually affects the batteries and the performance of the
arrowboard.
Solar panels can produce an electrical shock or burn unless care is
taken. Electrical current is always present.
Never attempt to work on solar panel in wet or damp conditions.
Solar panels have no ON/OFF switch, so before you begin any maintenance on the solar panel
or electrical connections on the arrowboard, be sure you first:
Disconnect the power supply at junction boxes.
Disconnect the red solar regulator lead.
Even when you have taken every precaution, be aware that the solar panels keep generating
current.
