10. Maintenance
Cleaning
Under most weather conditions, normal rainfall is sufficient to keep the Perlight Solar module
glass surface clean. If dirt build-up becomes excessive, clean the glass only with a soft cloth
using mild detergent and water. USE CAUTION WHEN CLEANING THE BACK SURFACE
OF THE MODULE TO AVOID PENETRATING THE SUBSTRATE MATERIALS. Solar Modules
that are mounted flat (0° tilt angle) should be cleaned more often, as they will not ‘’self clean’’
as effectively as modules mounted at a 15° tilt or greater. Perlight recommend cleaning the
modules during the early morning or evening, when the panels will be operating at a lower
temperature and producing little energy.
• Do not lean or stand on the modules during cleaning.
• Do not use high pressure water jets to clean the solar modules.
Annual Checks
Once a year, check the tightness of terminal screws and the general condition of the wiring.
Also, check to ensure the mounting hardware is tight and secure. Loose connections will
result in damage to the array.
Changed Perlight Solar modules must be of the same kind and type. Do not touch live parts
of cables and connectors. Use appropriate safety equipment when working (insulated tools,
insulating gloves, etc.).
Only trained personnel may carry-out repair work to the PV modules and
system components.
Cover the front surface of the solar module with an opaque or other material
when working on the modules. Solar modules generate high voltage when
exposed to sunlight.
