Go to the PV Support section on the JinkoSolar EU website. You can find it in the main navigation menu under 'Contact' or simply click button below Enter the module's Serial Number (SN) – a 24-digit code. . Unable to tell exactly when produced by just wattage for any of those. You know the wattage but not the sticker on anything? Really just look at the stickers on all the parts, they should all have production date (possibly encoded in the serial number), install date was probably probably 3-12. . Would you like to know date they assembled the panel or the date when the silicon ingot came out of the oven in Xinjiang? I find the datasheet for the panels and look at the copyright date or other date reference on the document. It doesn't tell you how old the specific panels are, but it. . Unlike milk cartons that show expiration dates, solar panels carry manufacturing timestamps affecting performance guarantees and degradation rates. Top-tier manufacturers like Trina Solar and Jinko embed production dates through: Wait, no – older panels aren't necessarily bad.
