560W Bifacial PERC Solar Panel Full Pallet — 31 Panels (SGP-560-SBD)

Solar Panel Wholesale — 560W Bifacial PERC Pallet 31 Panels

Solar panel wholesale at 560W bifacial PERC specification — the SGP-560-SBD delivers 31 panels per pallet for a total of 17,360W of peak capacity, certified by ETL to UL61730 standard and independently verified to ISO 9001, ISO 14001 and ISO 45001 management system standards. The PERC bifacial architecture captures energy from both panel faces, the ETL UL61730 certification opens every major North American market, and the wholesale pallet pricing makes this one of the most cost-effective high-output bifacial solar acquisitions available to professional installers and commercial developers.

Product Specifications

PERC Bifacial Architecture

The SGP-560-SBD combines PERC cell technology with bifacial glass construction — a combination that delivers meaningfully more energy per installed panel than either technology delivers independently.

PERC architecture adds a passivation layer to the rear of each monocrystalline cell, reflecting photons back through the silicon for a second conversion pass. In a monofacial panel, this rear passivation captures light that enters through the front face but misses on the first pass. In a bifacial design, the same rear passivation works in combination with a transparent rear glass that allows additional light to enter from behind — capturing both rear-reflected PERC light and ambient light incident on the panel’s rear face from the installation environment.

For solar panel buyers comparing bulk solar panels specifications across pallet formats, the PERC bifacial SGP-560-SBD delivers a higher annual energy yield per panel than monofacial PERC alternatives of equivalent nominal wattage — particularly in high-albedo installation environments.

ETL Certification and ISO Standards

The SGP-560-SBD is certified to UL61730 standard by ETL — Electrical Testing Laboratories, one of the two nationally recognised testing laboratories (NRTLs) in the United States for photovoltaic module certification alongside UL itself.

ETL UL61730 certification carries the same regulatory weight as direct UL certification for purposes of utility interconnection, building permit applications, insurance coverage and federal tax credit eligibility across all US markets. For solar panel wholesale purchasers sourcing for North American projects, ETL UL61730 certification is full-market coverage.

The additional ISO 9001 (quality management), ISO 14001 (environmental management) and ISO 45001 (occupational health and safety) certifications confirm manufacturing facility compliance with internationally recognised management system standards — a level of operational transparency relevant to institutional procurement processes.

Electrical Performance

At 49.76V open circuit voltage, the SGP-560-SBD is compatible with standard residential and commercial string inverters across all major inverter platforms. The 1500V maximum system voltage supports long string configurations that reduce inverter count and balance-of-system costs.

Warranty Coverage

The 25-year linear power warranty provides the performance assurance required for project financing, PPA agreements and long-term investment return modelling. The 12-year material and workmanship warranty covers component failures and manufacturing defects across the critical early system life period.

Pallet Shipping Details

These wholesale solar panels ship via LTL freight on full pallets. At 68.78 lbs per panel, professional offloading equipment is required. Confirm site access and offloading capability before ordering.

FAQ

What is the total capacity of this solar panel wholesale pallet? This solar panel wholesale pallet of 31 SGP-560-SBD panels delivers 17,360W (17.36kW) of peak capacity. Actual energy production depends on local irradiance, installation angle, shading and the additional bifacial rear-face gain achievable at your specific installation and ground surface.

What is ETL UL61730 certification? ETL is an Electrical Testing Laboratories NRTL — a nationally recognised testing laboratory authorised by OSHA to certify products to US safety standards including UL61730 for photovoltaic modules. ETL UL61730 certification carries identical regulatory acceptance to direct UL certification for utility interconnection, building permits, insurance and tax credit eligibility across all US markets.

How does PERC bifacial technology improve energy yield? PERC bifacial technology combines rear cell passivation — which reflects unabsorbed photons back through the silicon — with transparent rear glass that allows additional irradiance to enter from the installation environment’s ground-reflected light. Together, these features deliver more annual energy per panel than monofacial PERC technology of equivalent nominal wattage — particularly significant for ground-mounted and elevated rooftop systems with high-albedo surfaces beneath the array.

Are these solar panels by pallet appropriate for commercial projects? Yes — the SGP-560-SBD in solar panels by pallet format is a commercial-grade product. PERC bifacial architecture, 1500V system voltage, ETL UL61730 certification, ISO management system compliance and 25-year warranty terms meet the specification requirements of commercial EPC contractors and institutional procurement processes.

What is the per-panel cost at solar panel wholesale pricing? At full pallet pricing, the per-panel cost of the SGP-560-SBD represents a significant reduction compared to individual panel purchasing — the core advantage of solar panel wholesale procurement for professional buyers and developers. The pallet price shown above divided by 31 panels provides the effective per-panel rate.
