7.0 MAINTENANCE

· Do not make modifications to any component of the PV
module (diode, junction box, plug connectors or others).
· Regular maintenance is required to keep modules clear of
snow, bird droppings, seeds, pollen, leaves, branches, dirt
spots, and dust.
· Modules with sufficient tilt (at least 15°), generally do not
require cleaning (rain will have a self-cleaning effect). If
the module has become soiled, it shall be washed with
water and a non-abrasive cleaning brush or sponge du-
ring the cool part of the day. Do not scrape or rub dry dirt
away, as this may cause micro scratches.
· Snow should be removed using a soft brush.
· Periodically inspect the system to check the integrity of all
wiring and supports.
· To protect against electric shock or injury, electrical or
mechanical inspections and maintenance should be per-
formed by qualified personnel only.
· Please refer to Annex C (Module Cleaning Guide) for more
information on module cleaning.
