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
The SUN570-590 DE21M series is a monocrystalline silicon solar PV module offered in 570W, 575W, 580W, 585W, and 590W variants. It is listed as a new, 72- .
All variants share a stated size of 2278 × 1134 × 30 mm, an operating-temperature range of -40°C to +85°C, a maximum system voltage of 1500V DC (IEC), a 25A maximum series-fuse rating, and a stated power tolerance of 0% to +3%. Electrical values vary by power class.
Maximum-power voltage ranges from 42.99V for the 570W model to 43.71V for the 590W model, while maximum-power current ranges from 13.26A to 13.50A. Open-circuit voltage is stated from 51.99V to 52.63V, and short-circuit current from 13.89A to 14.13A.
Stated module efficiency rises from 22.07% for the 570W variant to 22.84% for the 590W variant. The listing states that customization and after-sales service are available. Packaging information specifies 36 modules per pallet and 720 modules in a 40HQ load, with wooden transport packaging.
Buyers should confirm the exact model and electrical rating on the quotation, datasheet, nameplate, and packing list before ordering. The supplied information contains conflicting warranty references: the headline mentions 30 years, while the product details state 25 years.
Confirm the applicable warranty duration, coverage, exclusions, start date, degradation terms, and claim procedure in the purchase contract.
Buyers should also verify the meaning and inspection criteria for the advertised “A Grade” classification, current CE documentation and its scope, , connector and cable specifications, mechanical-load ratings, fire classification, installation requirements, packaging protection, and project-specific system compatibility.
