Sensors and Accessories
Solar Panel
Inspect the module twice a year for overall integrity. Make sure that
connections to the battery are tight and free of corrosion.
Dirt accumulation on the module's front surface can reduce the light
energy collected by the module. If the module surface is dirty, gently
clean it with a soft cloth or sponge using water and mild detergent.
WARNING
Wear rubber gloves to protect yourself against possible electric
shock.
CAUTION
Do not use a scrub brush; it can damage the module front surface.
Wind Sensor
It is recommended to check the ball bearings of the anemometer and
the vane every year. If the cup wheel or the vane is not rotating
smoothly or creates detectable noise, the bearings must be replaced
(refer to Figure 115 on page 137).
