Installation Safety

1. Always wear protective head gear, insulating gloves and safety shoes (with rubber
soles).
2. Due to the risk of electrical shock, do not perform any work if the terminals of the
PV module are wet.
3. Do not install PV modules in the rain, snow or windy conditions
4. Insert interconnect connectors fully and correctly. Check all connections. Cables
should be secured to the PV module frames, support structure or raceway to prevent
movement. Keep connectors out of direct sunlight.
5. Do not touch the terminal box and the end of the interconnect cables with bare
hands during installation or under sunlight, regardless of whether the PV module is
connected to or disconnected from the system.
6. Do not unplug a connector if the system circuit is connected to an operating load.
7. Do not damage the back sheet of PV modules when mounting the PV modules.
8. Do not damage the surrounding PV modules or mounting structure when replacing a
PV module.
9. Keep children away from the system while installing.
10. Use UV resistant cable ties or other wire management hardware to secure the inter-
connect cables. Drooping cables may cause various problems, such as leading to
electrical shorts.
11. When installing PV modules on roofs or other structures, the appropriate safety
practices and safety equipment should be used at all times to avoid injury.

Site Selection

PV modules are intended for outdoor use only and not intended for use on any moving
vehicles. In most applications SCHOTT POLY™ modules should be installed in a location
where they receive the maximum sunlight throughout the year. In the Northern
Hemisphere the modules will normally face south, in the Southern Hemisphere the
modules will face north. Avoid trees, buildings or other obstacles that can cast shadows
on the modules. Take proper steps in order to maintain reliability and safety in case the
PV modules are installed in areas that have heavy snow /extreme cold / strong winds /
installations over, or near, water and areas where installations are prone to salt water
exposure or on small islands or in desert areas. If you are planning to use the PV modules
where salt water damage may occur, please consult with SCHOTT Solar to determine an
appropriate installation method, or if installation is possible.
1.5

Tilt Angle Selection

SCHOTT POLY™ modules produce the most power when the sun's rays strike the module
perpendicular to the module surface. To avoid performance losses in series circuits, ensure
that all modules have the same tilt and orientation. Your solar professional will be able to
determine the best tilt angle for your location.
