Safety and Installation Instructions - Document 514744 Rev B
©2015 SunPower Corporation. All rights reserved. Specifications included in this manual are subject to change without notice.
Modules that feature antireflective glass are susceptible to visible fingerprint
marks if touched on the front surface. SunPower recommends handling modules
having antireflective glass with gloves or limiting touching of the front surface. Any
fingerprints resulting from installation will naturally disappear over time or can be
reduced by following the washing guidelines in Section 6.0. Product datasheets
specify the glass type used by a particular module.
6.0
Maintenance
Visually inspect all modules annually for safe electrical connections, sound
mechanical connection, and freedom from corrosion. This visual inspection should
be performed from the ground, unless performed by trained SunPower dealers or
trained SunPower support personnel.
Periodic cleaning of modules is recommended, but is not required. Periodic
cleaning has resulted in improved performance levels, especially in regions with
low levels of annual precipitation (less than 18.25 inches [46.3 cm]). Consult your
dealer or supplier about recommended cleaning schedules for your area. To clean
a module, wash with potable, non-heated water. Normal water pressure is more
than adequate, but pressurized water (up to1500 psi) may be used. Fingerprints,
stains, or accumulations of dirt on the front surface may be removed as follows:
first rinse off area and let soak for 5 minutes. Re-wet the area and then use a soft
sponge or seamless cloth to wipe glass surface in a circular motion. Fingerprints
typically can be removed with a soft cloth or sponge and water after wetting. Do
not use harsh cleaning materials such as scouring powder, steel wool, scrapers,
blades, or other sharp instruments to clean module glass. Use of such materials or
cleaning without consultation will invalidate the product warranty
