GRUPPOSTG 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 mobile vehicles.
Do not install modules at such places as that are possible to be submersed.
GRUPPOSTG suggests that modules be installed in the working environment with
the temperature of - 20 °C to 46 °C which is the monthly average highest and
lowest temperature of the installation places. The extreme working environment
temperature for modules is -40°C to 85 °C.
Make sure that installed modules do not suffer wind or snow pressure that exceeds
the permissible maximum load.
Modules shall be installed in places free from shades throughout the year. Make
sure there are no light-blocking obstacles in the installation places.
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 can not 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 module 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.
4.2 Selection of tilt angles
Tilt angle of modules: Included angle between module surface and horizontal
surface; the module will obtain the maximum power output in direct facing of
sunlight.
Modules are preferred to be south-facing in the north hemisphere and north-
facing in the south hemisphere.
A specific installation angle shall be determined according to installation guide for
standard modules or suggestions from PV module installer.
GRUPPOSTG suggests that module installation tilt angle be no less than 10° so
module surface dust can be washed away easily by rainfall and times of cleaning
can be reduced. And it is easy for ponding to flow away and avoid water print on
the glass due to long time of water ponding which may further affect module
appearance and performance.
