Video: Make sure your LONGi panels are genuine before they go on your roof

LONGi has issued a warning to solar project developers, installers and investors over the operational and financial risks associated with counterfeit photovoltaic modules.
The company said counterfeit products marketed under the LONGi brand can expose project owners to reduced energy output, safety failures, invalid warranties and limited access to reliable after sales support. These risks can have material consequences for the performance and bankability of solar assets designed to operate for 20 to 30 years.

The warning follows a recent overseas case involving counterfeit modules sold under the LONGi name. The company involved was fined and its controller received a prison sentence after legal proceedings.
LONGi said the purchase price of a module represents only one element of a solar project’s lifecycle cost. Product authenticity, manufacturer warranty validity, traceable procurement documentation and ongoing technical support remain important throughout the operating life of a solar plant.
The manufacturer is urging buyers to procure equipment through officially authorised distributors and to retain contracts and invoices for their records. Project owners and contractors can verify module authenticity using the official LONGi Module Authenticity Checker.
Verification can be completed by entering the module barcode or digital string code into the company’s online platform. Users may also scan the QR code on the module nameplate or shipping pallet to confirm product specifications and associated quality information.
LONGi said installers and asset owners should locate the serial number and barcode on the rear module sticker or beneath the front glass before checking the details through official channels. The verification process is intended to help the market identify genuine products before installation and protect the expected long term returns of solar investments.
