INSTALLATION MANUAL
CRYSTALLINE SOLAR MODULES
4.1 Product identification
Each individual module has a unique serial number laminated behind the glass and another permanently
attached to the backsheet of the module on the product sticker. Note all serial numbers in a safe place for your
future records.

SITE SELECTION
•
Sapphire Solar modules can be mounted in landscape or portrait orientation.
•
For optimum energy production, solar modules should normally be mounted facing the equator at
an angle to the horizontal plane equivalent to the latitude of the installation. In the event that you
mount the solar modules at a different angle or orientation then the annual energy production may
potentially be adversely impacted.
•
When installing solar modules on a roof always leave a safe working area between the edge of the
roof and the external edge of the solar array.
•
Position the modules to minimize the chances of shading at any time of the day. Shading can
normally be minimized by ensuring that the distance between the obstruction and solar array is
greater than three times the obstruction’s height.
•
Any slope of less than 1: 2.4 is required to maintain the fire class rating.
•
Avoid using a mounting method that will block the drainage holes in the module frame.
•
When all solar modules are mounted in the same plane and orientation then all can be expected to
have similar performance throughout the day and can be connected together to the same inverter
channel.
•
If solar modules on the same installation are mounted at different angles or orientations then energy
production can normally be optimized by connecting the different orientations to different inverters
(or different MPPT if the inverter has more than one MPPT). Refer to inverter manufacturers for
further guidelines.
•
Do not install PV modules in a location where they will be immersed in or continually exposed to
water.
