4 products · 550W

550W is a power class, not a product.

The 550W stock above is 4 different modules from 4 manufacturers. Each carries its own SKU, price ladder, origin and datasheet — a figure in one block says nothing about the block beside it, and a purchase order names the SKU rather than the wattage.

Frequently asked questions

What is the 550W module specification?

Mission Solar, Sunpro Power, Waaree, ZN Shine 550W inventory (BI-55-550-JQC41300, MSH10-550HT4T, SPDG550-144M10, ZXM7-SHLDD144-550W) uses P-Type PERC (Passivated Emitter Rear Cell) technology with Silver frame. Pallet configuration: 31–36 modules per pallet (varies by lot). Dimensions and full technical specs are available in each SKU datasheet.

How much 550W inventory is currently available?

4.23 MW of 550W modules are currently in U.S. inventory across CA, TX warehouses. Availability is updated every 60 seconds from our live inventory system. Contact our team for exact allocation and pallet confirmation.

What is the pallet configuration for 550W modules?

550W modules are packaged as 31–36 modules per pallet (varies by lot). Public pallet pricing is shown in the inventory table above for 1–19 pallet orders. Container quantities (20+ pallets) are priced via RFQ with better per-watt economics for volume buyers.

Is the 550W module TOPCon or PERC?

The 550W modules use P-Type PERC (Passivated Emitter Rear Cell) cell technology. Proven P-Type PERC technology — bankable, widely accepted by project finance lenders. Strong value for cost-per-watt-driven ground mount procurement.

What is the minimum order for 550W solar panels?

How quickly do 550W modules ship from U.S. warehouses?

Ready inventory ships within 3–5 business days after signed PO and deposit. Freight is quoted separately from each origin warehouse. Contact our team for exact shipping timelines by destination.

Is the BI-55-550-JQC41300 the same module as the BI-55-545-JQC41200?

No. Both belong to Waaree's Ahnay Series, and Waaree publishes them in one datasheet — but in separate columns, and they are separate products with separate SKUs and separate prices. BI-55-550-JQC41300 is rated 550 W at 49.91 V open circuit, 13.96 A short circuit and 21.36% module efficiency. BI-55-545-JQC41200 is rated 545 W at 49.76 V open circuit, 13.9 A short circuit and 21.17% module efficiency. We stock and quote them independently, so a purchase order for one never ships as the other.
