6 FAQs about [Longi photovoltaic panel grade classification]
What if a Longi PV module is broken?
To inform the LONGi customer service personnel within two weeks when modules are found broken or other significant abnormality. Refer to the《LONGi PV Module Operation and Maintenance Manual》for details on module maintenance.
How to calculate VOC in a Longi module?
(LONGi modules maximum system voltage is DC1000V/DC1500V---ac-tually system voltage is designed based on the selected module and inverter model.) The correction value of VOC can be calculated by the following formula. CVoc=1-βVoc×(25-T) T: The expected lowest temperature of the installation site.
What is the maximum system voltage for Longi modules?
(LONGi modules maximum system voltage is DC1000 V/DC1500 V---actually system voltage is designed based on the selected module and inverter model) The correction value of VOC can be calculated by the following formula. T: The expected lowest temperature of the installation site.
Should Longi modules have the same orientation and tilt angle?
LONGi modules connected in string should be installed with the same orientation and tilt angle. Diferent module orientation and tilt angle may result in diferent levels of solar irradiation and also power generation.
Can a third party grounding device be used for a Longi module?
Mounting holes on modules that are not occupied can be used for installing grounding devices. The third party grounding device can be used for grounding of LONGi modules but such grounding method shall be proved to be reliable.
Where can I find the latest version of the longi installation manual?
It is recommended to visit our website regularly at for the latest version of this installation manual. If customers fail to install modules as per requirements set forth in this manual, the limited warranty provided for customers will be invalid.
