Wholesale 550W Solar Panels by the Pallet
The Seraphim 550W bifacial solar panel is a Tier 1 monocrystalline PERC module with 21.0% efficiency, half-cut cells and dual-glass construction. It’s sold here as a full pallet of 31 panels, delivering 17.05kW of DC capacity at wholesale pricing. Each panel produces 550W from the front, and its glass back captures reflected light, adding up to 30% more energy, depending on how and where it’s installed.
Buying solar panels one at a time costs more and slows projects down. Buying bulk solar panels by the pallet changes that. You lock in a lower per-watt cost, get matching panels from the same production batch, and receive enough modules for a complete residential, farm or commercial array in one delivery. Better still, we stock this pallet in our Houston, Texas warehouse and ship within 2 days.
Key Features
550W Mono PERC With Half-Cut Cells
Large-format monocrystalline PERC cells with half-cut technology reduce internal resistance and heat buildup. As a result, each panel delivers more power in high temperatures and keeps producing when part of the panel is shaded.
Bifacial Energy Gain
The transparent rear glass lets the panel absorb light reflected from the ground, snow, gravel or a white roof. In elevated installations, that rear-side gain can add up to 30% more energy, which lowers the cost of every kilowatt-hour the system produces.
Dual-Glass Durability
The panel uses 2.0mm anti-reflective semi-tempered glass on both sides, framed in anodized aluminum. It’s rated for 5,400 Pa of front-side load (snow) and 2,400 Pa of rear-side load (wind). It also operates from -40°C to 85°C, and an IP68 junction box with 3 bypass diodes protects the electrical connections.
Tested Quality and Certifications
Seraphim manufactures under ISO 9001, ISO 14001 and ISO 45001 management systems. On top of that, multiple electroluminescence (EL) inspections screen for micro-cracks before shipment, and the module carries UL and IEC certification.
550W Bifacial Rear-Side Power Gain
Rear-side gain depends on mounting height, tilt and ground reflectivity (albedo). Here’s what a 550W panel can produce at each gain level:
| Rear-side gain | Total power output |
|---|---|
| 10% | 605W |
| 15% | 633W |
| 20% | 660W |
| 25% | 688W |
| 30% | 715W |
Flush-mounted rooftop panels typically see little rear gain. By contrast, ground mounts and carports raised over light-colored surfaces see the most.
What’s on One Pallet
- 31 panels × 550W = 17.05kW of DC capacity
- About 2,230 lb (1,010 kg) of panels, before packaging
- One production batch, so electrical characteristics match across your array
- 18 pallets per 40ft container (558 panels, about 307kW) for larger projects
A full pallet arrives by freight. Plan for a forklift or a liftgate delivery, and ask our team to arrange liftgate service if your site needs it.
Inverter Compatibility and String Sizing
At 17.29A operating current and 18.39A short-circuit current, this panel needs an inverter or MPPT input that accepts at least 18.4A. Many microinverters and older string inverters cap input current around 13–15A, so check your equipment first.
For string sizing, the 38.1V open-circuit voltage rises in cold weather. Here’s how many panels fit in series at around -10°C (14°F):
| Inverter max DC voltage | Max panels per string |
|---|---|
| 500V | 12 |
| 600V | 14 |
| 1,000V | 24 |
| 1,500V | 36 |
Always calculate with your site’s record low temperature. For matched systems, pair these panels with a high-current Sol-Ark hybrid inverter or another hybrid inverter from our US solar hybrid inverter range. Our team can also check your string design before you order.
Best Applications for 550W Bifacial Panels
- Ground-mount arrays for homes, ranches and farms, where height and ground reflection maximize rear-side gain.
- Solar carports and pergolas, where bifacial glass captures light reflected from pavement.
- Commercial flat roofs with white or reflective membranes.
- Off-grid and backup systems paired with battery storage.
- Large residential arrays, where roof space and racking can handle a 7.8 ft panel.

Frequently Asked Questions
How much power does a pallet of 550W solar panels produce?
One pallet of 31 Seraphim 550W panels provides 17.05kW of DC capacity. In a sunny US location, that typically produces roughly 70–85kWh per day, depending on orientation, shading and climate.
Are Seraphim solar panels Tier 1?
Yes. Seraphim is recognized as a Tier 1 solar manufacturer, a rating that reflects production scale, financial stability and bankability for large projects.
What is a bifacial solar panel?
A bifacial solar panel produces power from both sides. The front captures direct sunlight, while the glass rear captures light reflected from the ground or nearby surfaces, adding up to 30% more energy in ideal installations.
Are 550W panels good for residential roofs?
They can work, but at about 7.8 ft long and 72 lb, they suit large roofs, ground mounts and carports best. For smaller roofs, a lower-wattage, smaller-format panel is often easier to fit and install.
Will these panels work with microinverters?
Only with microinverters rated for high-current modules. At 17.29A operating current, this panel exceeds the input limit of many microinverters, so confirm your inverter accepts at least 18.4A per input.
How much does a pallet of 550W solar panels cost?
Pallet pricing appears on this page and works out lower per watt than buying single panels. For multiple pallets or container orders, contact Liniotech for volume pricing.
Do you sell solar panels in bulk for nonprofit organizations?
Yes. Liniotech supplies bulk solar panels to nonprofits, schools, churches and community projects. Contact our team for multi-pallet and project pricing.
How are the panels shipped?
Each pallet ships by freight from our Houston, Texas warehouse, usually within 2 days, with free shipping in the USA. Plan for a forklift or liftgate delivery, since a full pallet weighs over 2,200 lb.
What warranty comes with Seraphim 550W panels?
Seraphim provides a 15-year product warranty and a 30-year linear power output warranty on this bifacial PERC module.
