Buyer's Digest
Use this page as a product-first sourcing checkpoint before sending an RFQ. Category: Solar Panels And Modules. Confirm application fit, capacity, materials, destination, lead time and compliance requirements before comparing suppliers.
Original product description
This LONGi monocrystalline half- , 525 W, 530 W, 535 W, 540 W, and 545 W power classes. Stated module efficiency ranges from 20.3% for the 520 W version to 21.3% for the 545 W version, with a non-negative power-output tolerance of 0 to +5 W.
The listed construction comprises a 3.2 mm high-transmission, low-iron tempered-glass front cover and an anodized aluminum-alloy frame. Available frame and backsheet descriptions include a black frame and white, black, or transparent backsheet options. The junction box is rated IP68 and contains three diodes.
The module measures 2256 × 1133 × 35 mm and has a stated weight of 32.3 kg. Published electrical values vary by power class. Maximum-power voltage rises from 41.05 V at 520 W to 41.80 V at 545 W, while maximum-power current ranges from 12.67 A to 13.04 A.
Open-circuit voltage is listed between 48.90 V and 49.65 V, and short-circuit current between 13.57 A and 13.92 A. The stated maximum series-fuse rating is 30 A, operating-temperature range is -40°C to +85°C, and protection classification is Class I. A mechanical-load value of 5400 Pa is also listed.
For procurement, buyers should confirm the exact electrical datasheet and configuration for the selected wattage. The source information contains inconsistent , 6 × 24 orientation in another—so the final .
Buyers should also request model-specific evidence for the stated CE, ISO, TUV, and EST certifications;confirm whether the required backsheet and frame combination is available;and verify the meaning and applicable test standard behind the listed Type 29 fire rating.
The stated 25-year warranty should be reviewed for its coverage, exclusions, claim procedure, and responsible warrantor.
Packaging, shipment quantity, installation responsibility, system-voltage limits, connector details, and compatibility with the planned inverter, mounting hardware, and electrical design should all be confirmed in the final purchase specification.
