4.1 Installation Site and Working Environment
•
The modules cannot be used in space
•
Do not manually focus sunlight with mirrors or magnifying glass onto modules.
•
LONGi modules shall be installed on proper buildings or other appropriate places (such as ground, garage, building outer
wall, roof, PV tracking system) but shall not be installed on any vehicles.
•
Do not install modules at places that are possible to be flooded.
•
LONGi suggests that modules be installed in the working environment with the temperature of -20
℃
to 50
℃
of which is
the monthly average highest and lowest temperature of the installation sites. The extreme working environment
temperature for modules is -40
℃
to 85
℃
.
•
Make sure that installed modules do not suffer wind or snow pressure that exceeds the permissible maximum load limit.
•
Modules shall be installed in places free from shadows throughout the year. Make sure there are no light-blocking
obstacles in the installation sites.
•
Carry out lightning protection for modules installed in places with frequent lightning and thunder.
•
Do not install modules in places with possible inflammable gases.
•
Modules cannot be used in environments with too much hails, snows, flue gas, air pollution and soot or in places with
strong corrosive substances such as salt, salt mist, saline, active chemical steam, acid rain, or other substances
corroding modules, affecting modules’ safety or performance.
•
Please take protective measures to ensure reliable and safe installation of modules in severe environments such as
heavy snow, cold and strong wind or islands close to water and salt mist or deserts.
•
LONGi modules passed the IEC61701 salt spray corrosion test, but the corrosion may still occur on where the modules
frame is connected to the bracket or where the grounding is connected. In case LONGi modules are installed
50m –500m away from the ocean side, stainless steel or aluminum materials are need to be used to contact the PV
modules, and the connection point should be protected with anti-corrosion measures.
