Pre-Shipment Measurement.
In China.
By Pasan.
We bring our own mobile lab to your supplier's factory in China and measure your modules before they ship, independently, while the goods are still unpaid and you still have leverage.

Our mobile lab goes to the factory.
We drive a Pasan mobile lab to your supplier's plant in China and measure a sample of your order before it ships: IV power plus EL imaging, against an independent, METAS-traceable reference. You get an accept or hold decision while the goods are still unpaid.

The flash list is not your friend.
Since 2017 the numbers flipped. TÜV Rheinland's 2025 study found 65.7% of 519 modules below their nameplate, up from 28.3% a decade earlier; Fraunhofer ISE sees about 1.3% average shortfall since 2020. Your contract and your yield model assume the nameplate is real.

On 100 MW, 1.5% is a power plant you never get.
A 1.5% shortfall on a 100 MW order is 1.5 MW you paid for that never produces, worth millions over 25 years. Once the modules are paid and shipped, clawing it back means counter-measurements, lawyers and freight across borders. Acting before the container closes is the cheap moment.
