• For permission to use mounting methods not described in the Mounting Guide (ETL listed version), please
consult Evergreen Solar. Failure to do so will void the warranty and panecertification.
• Always follow the mounting equipment vendors’ installation instructions in addition to the instructions found
in the Mounting Guide (ETL listed version). In cases where the vendors’ instructions are more stringent
than those detailed in the Mounting Guide (ETL listed version), the vendors’ instructions shall apply.
• In cases where the maximum permissible loading determined by the mounting equipment vendor is less
than the maximum permissible load stated in the Mounting Guide (ETL listed version), the maximum loads
determined by the vendor should always be used.
• The maximum permissible loads apply to uniformly distributed wind or snow loading. Care should be taken to
avoid mounting panels in areas that are prone to drifting snow, icicle and/or ice dam formation.
Operation and Maintenance
• No routine maintenance is required. However it is advisable to perform periodic inspection of the panels for
damage to glass, back-skin, frame, junction box or external electrical connections.
• Check electrical connections for loose connections and corrosion.
• PV panels can operate effectively without ever being washed, although removal of dirt from the front glass
can increase output.
• Water can be used for regular washing or rinsing of the front glass to remove dust, dirt or other deposits.
• To remove ingrained dirt, the glass can be washed with a micro-fiber cloth and ethanol or a conventional
glass cleanser.
• No aggressive and abrasive cleansers or chemicals should ever be used on the front glass. No alkali based
chemicals should be used, including ammonia based solutions.
• Always wear rubber gloves for electrical insulation whilst maintaining, washing or cleaning panels.
Underwriters Laboratories and Canadian Standard ULC/ORD-C1703-01 Information
• Under normal conditions, a photovoltaic panel is likely to experience conditions that produce more current
and/or voltage than reported at Standard Test Conditions. Accordingly, the values of Isc and Voc marked on
this panel should be multiplied by a factor of 1.25 when determining component voltage ratings, conductor
capacities, fuse sizes, and size of controls connected to the PV output.
• Refer to section 690-8 of the National Electric Code (NEC) for an additional multiplying factor of 125% (80%
de-rating) which may be applicable.
• Conductor recommendations: Single conductor cable, type USE-2 (non-conduit) or PV-WIRE, 14AWG
(2.5mm²) minimum.
• For compliance with Canadian Standard ULC/ORD-C1703-1, the installation shall be in accordance with CSA
C22.1, Safety Standard for Electrical Installations, Canadian Electrical Code, Part 1.
