Aptos 550W Pallet of Bifacial Solar Panels | 31 Panels: Frequently Asked Questions
What's included in the pallet?
31 Aptos 550W Bifacial solar panels on one pallet. Racking, clamps, wiring, inverters and installation are not included. Call (303) 876-7654 and we'll help you plan the rest of the system.
How much power is on a pallet?
At the rated 550W per panel, 31 panels add up to about 17.05kW of DC capacity at standard test conditions.
How is the pallet shipped?
The pallet weighs about 2,208 lb (1,002 kg). Plan for freight delivery and a way to unload it. Call (303) 876-7654 if you want to talk through delivery before you order.
How should I size strings and wiring?
Aptos lists 42.00V at maximum power and 49.80V open-circuit and a 1,500V DC maximum system voltage with a 30A maximum series fuse rating. Have your installer calculate string length with temperature-corrected voltage for your climate. Call (303) 876-7654 if you want help.
How much extra power does the rear side add?
Aptos's datasheet lists rear-side gain scenarios: 578W at 5% gain, 633W at 15% gain and 688W at 25% gain, with module efficiency rising with each. Aptos doesn't publish a bifaciality factor for this model, and real gain depends on ground cover, mounting height and tilt. Call us and we'll help you estimate it for your site.
How are the panels mounted?
Aptos recommends top-mount clamps placed about one quarter of the module length from each end, and keeping clamps off the front glass. The frame also has 14 × 9 mm mounting holes for M8 bolts at 12.5 to 18 Nm. Minimum tilt is 5 degrees so water can drain.
What weather can they handle?
The junction box is IP68 rated. Aptos lists 5,400 Pa on the front and 2,400 Pa on the rear with mounting-hole installation, and Level 6 salt mist testing. Aptos doesn't publish an operating temperature range for the module.
How long are the warranties?
Aptos lists a 30-year product warranty and a 30-year linear power warranty. Aptos's standard module warranty lists 2% degradation in year 1 and 0.54% per year after that.
Do you offer financing or price matching?
Yes. We offer 0% APR financing through Affirm at checkout, and our Lowest Price Guarantee applies. If you find this Aptos pallet cheaper at another authorized dealer, call us at (303) 876-7654 before you order.
