2. Current level label: Divide modules as per their optimal working current and
there are values:
H, M or L (H means the highest current level). The best practice is to install
modules with the same current level (such as H) in one strand in the process of
installation.
3. Serial No.: Each module has a unique serial number which is solidified inside the
module permanently and it can be seen from front top of the module. Each serial
number is put in before laminating of the module.
1. Aluminum alloy frame 2. PV tempered glass 3. Packaging EVA 4. Cells 5. Back plate 6. Silica gel
7. Connecting box 8. Nameplate 9. Cables 10. Connector 11. Mounting hole 12. Grounding hole
13. Leakage hole 14. Cell

GRUPPOSTG module is considered to be in compliance with UL 1703 only when the
module is mounted in the manner specified by the mounting instructions below.
When the module is installed on roof, it is necessary to take the overall fire rating
of the finished structure as well as later overall maintenance into account. The
roofing PV system shall be installed after assessment by construction experts or
engineers and with official analysis results for the entire structure. It shall be
proved capable of supporting extra system bracket pressure, including PV module
weight.
For your safety, please do not work on the roof without safety protective measures
which include but not limited to fall protection, ladder or stair and personal
protective articles.
For your safety, please do not install or handle modules in unfavorable conditions
including butnot limited to strong wind or gust, damp or sandy roofs.
