6 FAQs about [Detailed drawing of the structure of LONGi photovoltaic panels]

Can Longi photovoltaic modules produce DC current under sunlight?

Page 9 INSTALLATION MANUAL FOR LONGi PHOTOVOLTAIC MODULES OF DG 3.4 Electrical Performance Safety PV modules can produce DC current under sunlight. Any contact of exposed metal at module's wiring parts may result in electrical shock or burn. Any contact of 30 V or larger DC Voltage can be fatal.

Are LONGi Solar modules corrosion resistant?

LONGi Solar modules have passed IEC61701 salty mist corrosion test, but the corrosion may occur at the joints connecting the module frame and the mounting system or grounding joints. LONGi modules can be installed less than 500mm but more than 50m from the seaside but stainless steel or aluminum shall be applied to contact solar PV Modules.

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.

Can Longi modules be used in space?

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.

What happens if a hot spot occurs in a LONGi Solar module?

LONGi Solar module’s junction box contains bypass diodes in parallel connection with the cell strings. If hot spot occurs partially in the module, the diodes will come into operation to stop the main current from flowing through the hot spot cells, so as to restrain module heating and performance loss.
