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 sopay 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
The panel does
not (or almost)
produce anymore
in spite of a
sunny weather.
When measuring with a voltmeter,
my panel, connected to a PWM
regulator, displays 12,5V instead of
18,5V
28/49
The regulator is in a charge
maintenance phase (called
« floating » phase), limiting
The battery is
the charge only to
loaded
compensate for the self-
discharge of the battery (by a
few mmA)
Your panel is totally or
partially in the shadow.
Modules are dirty
The battery is
not loaded
Sealing problem: the panel
has suffered damage
Panel anomaly
With a PWM regulator, this
operation is normal. The
electrical circuit is common,
so the voltage value is the
lowest, meaning the battery
voltage.

Causes
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.
Check connection cables
Clean the panel following
recommendations.
