Product Overview
JAM66D45 LB is JA Solar's 66-cell large-format N-type TOPCon bifacial module — 595–620W — suited for commercial rooftop and C&I ground mount projects using 1500 V string inverter systems. At 620W, this panel reduces the number of modules per 100 kWp from approximately 180 (at 550W) to 161, directly cutting structural and cabling component counts.
The D45 cell series uses JA Solar's high-density cell interconnection, improving module efficiency above 22.5% and delivering a bifacial factor above 75%. The 66-cell format produces a slightly shorter module than 72-cell equivalents at comparable wattage — which can ease purlin-span compliance on commercial metal rooftops.
OmniSol coordinates JAM66D45 LB with H1Z2Z2-K or PV1-F DC cable, 1500 V DC SPD and MCCB packages for large string configurations. Rail span and purlin spacing should be verified against the module's frame dimensions before finalising the mounting design.
Applications
Residential rooftop PV projects
C&I rooftop solar projects
Ground-mounted PV projects
Project BOM sourcing with panels and BOS
Installation Notes
Confirm module dimensions and clamp zone before mounting design.
Confirm Voc, temperature coefficient and inverter MPPT limits before final string design.
Confirm destination certificate and warranty documents before shipment.

Frequently Asked Questions
Can OmniSol quote this panel with mounting and BOS parts?
Yes. We can treat the panel as part of a wider project BOM and match mounting, cables, connectors, protection, inverter-side accessories and export packing.
Is this exact panel always in stock?
Stock changes quickly. The listed model is a sourcing family under an OmniSol SKU; exact wattage, datasheet, certificate, warranty and delivery time are confirmed during RFQ.
Can I use this SKU if the brand generation changes?
Yes. Keep the OmniSol SKU as the inquiry reference, then send the preferred model, wattage, certificate requirement and destination market. We will check the exact model or current-equivalent alternatives before quotation.
