660W Solar Panels for Project Supply

The 660W Tongwei TWMNH-66QD and 660W Canadian Solar TOPBiHiKu6 630–660W options we supply both have nominal dimensions of 2,382 × 1,134 × 30 mm. Their stated weights differ: 32.7 kg for the Tongwei model and 32.8 kg for the Canadian Solar model. These specifications do not apply to every 660W panel. So please confirm the exact model and drawing before arranging mounting, handling, or bulk transport.

Divide your target DC array capacity in watts by 660 and round up for an initial count. For at least 100 kWp, this gives 152 panels, totaling 100.32 kWp. We recommend checking that preliminary count against string design, inverter limits, and available space.

Compare the exact models, including operating voltage and current, dimensions, weight, efficiency, warranty terms, and applicable certificates. A shared 660W rating does not make modules interchangeable. We recommend checking that the selected model matches the inverter and mounting design before comparing commercial offers.

For our Canadian Solar TOPBiHiKu6 630–660W option, the minimum order is one pallet of 36 modules. At 660W each, this represents 23.76 kW of rated DC capacity. Tongwei TWMNH-66QD also has a 36-module pallet configuration, but packing quantity alone does not establish its minimum order. Tell us your preferred model and quantity so we can confirm the order requirements and packing arrangement before quoting.

A useful quotation should identify the module model, quantity, unit price or price per watt, and agreed delivery terms. Check freight, insurance, duties, taxes, and local delivery separately so you understand the total delivered cost. We recommend comparing offers for the same destination and specifications. Share your preferred brand, order quantity, destination port, and delivery requirements so we can prepare a quotation for your specific shipment.

Delivery time depends on the exact model, stock availability, order quantity, destination, and transport arrangements. Order preparation or production time is separate from freight transit, customs clearance, and final delivery. We recommend agreeing on a dispatch date and estimated arrival window before committing to a project schedule. Tell us your required arrival date so we can confirm availability and shipping arrangements rather than apply one lead time to every brand.
