About

LONGi Solar

A world leading mono-crystalline solar module manufacturer which achieves the better LCOE (levelized cost of electricity) solutions.

LONGi Solar is a world leading manufacturer of

high-e�ciency mono-crystalline solar cells and

modules. LONGi Solar focused on MONO 18 years and is

the largest supplier of mono-crystalline silicon wafers in

the world, with total assets above $2.7 billion. (2016)

It also plans to have 45 GW of monocrystalline wafer

production capacity by the year 2020.

Armed and powered by advanced technology and long

standing experience in the �eld of mono-crystalline

silicon, LONGi Solar shipped approximately 4.5GW

products in 2017, with over 100% rate of growth in

three consecutive years. The Company has its

headquarters in Xi’an and branches in Japan, Europe,

North America, India, Malaysia, Australia and Africa.

With strong focus on R&D, production and sales &

marketing of mono-crystalline silicon products, LONGi

Solar is committed to providing the better LCOE

solutions as well as promoting the worldwide adoption

of mono-crystalline technology.

Higher e�ciency under low irradiation

Higher e�ciency in the infrared wave length

PERFORMANCEDislocation density and Fe impurity a�ect minority carrier lifetime which is concerned with performance.

Low O impurity determines a good LID performance.

Multi silicon structure

Mono silicon structure

Mono-C-Si modules generate less heat than multi-c-Si modules.

Therefore, the nominal operating cell temperature (NOCT) for a mono cell is lower than for a multi-cell. By operating at a lower temperature, mono cells and modules generate more energy.

Lower initial light induced degradation (LID), means higher reliability and more energy generated than standard mono or multi -crystalline modules.
