CLEANING MAINTENANCE
Dust and dirt on the panel surface reduce electrical production. Clean regularly this surface with a soft
towel and a soft brush, using soapy water.
Never use corrosive products.
Never use high pressure cleaners or automatic cleaning station.
Check regularly the quality of your panels connections.
Be careful : panels and brackets exposed to the sun for a long period may cause burns. Protect
yourself.
PROBLEMS, CAUSES, SOLUTIONS
Problems
Causes
Solutions
The panel does
not (or almost)
produce anymore
in spite of a
sunny weather.
The battery is
loaded
The regulator is in a charge
maintenance phase (called
« floating » phase), limiting
the charge only to
compensate for the self-
discharge of the battery (by a
few mmA)
The panel will produce
normally again as soon as
the battery needs to be
loaded.
Increase your battery
capacity in order to store the
extra production.
The battery is
not loaded
Your panel is totally or
partially in the shadow.
Check connection cables
Panels are dirty
Clean the panel following
recommendations.
Sealing problem: the panel
has suffered damage

Panel anomaly
When measuring with a voltmeter,
my panel, connected to a PWM
regulator, displays 12,5V instead of
18,5V
With a PWM regulator, this
operation is normal. The
electrical circuit is common,
so the voltage value is the
lowest, meaning the battery
voltage.
No solution necessary
