About 550-709W Solar Panels

550-709W large-format modules are built for commercial rooftops, ground mounts, and solar farms — the highest watts-per-panel class we stock. This collection features Canadian Solar HiKu6 and TOPBiHiKu6 N-type bifacial (550-625W+), plus ZNShine, Boviet, CW Energy, and Philadelphia Solar in 132/144-half-cell formats.

At this size, a 100kW commercial array takes under 160 panels. Bifacial TOPCon models add rear-side gain on ground mounts with reflective surfaces. These modules are pallet- and truckload-priced — contact us for project quotes on multi-pallet orders.

Frequently Asked Questions

Can I use 550W+ panels on a home?

Usually no — and not because of output. These modules are 7.5-8 feet long, weigh 60-75 lbs, and their electrical characteristics are tuned for commercial string inverters. They're designed for ground mounts, carports, and flat commercial roofs where two-person handling is standard.

What's the advantage of bifacial TOPCon in this class?

N-type TOPCon cells deliver higher efficiency (22%+) with lower annual degradation than PERC, and the bifacial glass-glass construction harvests reflected light on the rear side — real-world gains of 5-15% over gravel, white membrane, or sand. That combination is why utility-scale has standardized on it.

How do commercial panels ship?

Palletized LTL freight, 31-36 panels per pallet depending on format, with curbside delivery. A full truckload runs 20+ pallets. For multi-pallet orders our logistics team will quote the most economical option — liftgate, dock, or flatbed.

What warranties do these carry?

Commercial-class N-type modules typically carry 15-25 year product warranties and 30-year linear performance warranties with roughly 1% first-year degradation and 0.4% annually thereafter. Canadian Solar's TOPCon line guarantees around 87% output at year 30.

Do you offer project pricing for large orders?

Yes — pallet, multi-pallet, and container pricing is where this class makes its money. Send us the module model, quantity, and delivery zip code and we'll return a delivered price, usually same business day.
