The Longi Solar Panel reviews comprehensively evaluate both strengths and weaknesses. Despite starting in Australia in 2017, Longi has rapidly become a top seller. Notably, Longi, although a newer brand, achieved a trusted status in 2020, following SunPower and LG.
A Quick Review: The Longi Company History
Founded in 2000, by 2007 Longi boasted 100 tons of mono-silicon production capacity, enough for at least one gigawatt of solar panels. Moreover, rapid growth followed, with Longi becoming the world’s largest solar manufacturer, hitting an estimated 18GW production capacity in 2020, making it the biggest Solar Panel manufacturer globally.
As a result, Longi manufacturing plants successfully expanded to China, Vietnam, and Malaysia. Then, Longi solar panels entered the Australian market in 2017 and swiftly gained popularity as a top seller. Remarkably, Longi is the sole brand designated as an AAA-rated brand by ModuleTech Bankability Rating in the Q3 2020 ranking.
Indeed, Longi maintains an office in Sydney, Australia, a crucial factor to consider. This eradicates potential international frustrations and empowers customers with a national support helpdesk for emergencies. In case of warranty claims, the Australian Team promptly addresses issues within the country.
