590W Bifacial N-Type Monocrystalline Solar Panel Full Pallet — 31 Panels (SGN-590-BDG1)

Sungold Solar Panels — 590W Bifacial N-Type Full Pallet 31 Units

Sungold solar panels at their highest-output specification — the SGN-590-BDG1 is a 590W Bifacial N-Type monocrystalline panel available in full pallet format of 31 units for a total of 18,290W of peak capacity. This is the flagship panel in the Sungold wholesale range — combining the superior degradation resistance and temperature performance of N-Type silicon with bifacial dual-face energy capture, ETL UL61730 certification, ISO management system compliance and a 30-year linear power warranty in a 144-cell large-format panel that delivers more watts per installation point than any other panel in this range. For commercial developers, professional installers and large-scale residential buyers purchasing solar panels by pallet, the SGN-590-BDG1 is the maximum-output specification available.

Product Specifications

590W — Maximum Output in the Range

At 590W per panel, the SGN-590-BDG1 delivers the highest rated output of any sungold solar panel currently available at wholesale pallet pricing. The significance of this specification extends beyond a single number — higher wattage per panel means:

• Fewer panels required for any given system size — reducing installation time, mounting hardware, cabling and labour cost
• Higher output per roof or ground footprint — critical where space is limited
• Reduced balance-of-system costs — fewer panels means fewer mounting points, fewer cable connections and fewer combiner inputs
• Lower installation cost per kW — the economics that matter most to commercial developers and professional installers

For solar panel buyers procuring at the high end of the specification range, the SGN-590-BDG1 represents the most output-dense option in the solar panel pallets format available — 18,290W from 31 panels in a single pallet shipment.

N-Type Bifacial at Full Scale

The SGN-590-BDG1 scales N-Type bifacial architecture to its maximum practical panel size — 144 cells in an 89.69 × 44.65 inch format that packs 590W into standard commercial panel dimensions.

N-Type silicon delivers lower light-induced degradation than P-Type — meaning the gap between rated and actual output remains smaller throughout the 30-year warranty life. For projects where long-term performance modelling determines financing and return metrics, N-Type’s degradation advantage compounds meaningfully across the warranty horizon.

The bifacial glass construction adds rear-face irradiance capture on top of N-Type’s front-face efficiency advantages. For ground-mounted commercial arrays, carports, canopies and elevated rooftop installations over reflective surfaces, the rear-face contribution from sungold solar panels in bifacial format can add 10–25% above the rated front-face output — substantially improving the energy yield metrics used in commercial project financial models.

30-Year Linear Power Warranty

The SGN-590-BDG1 carries a 30-year linear power warranty — the same industry-leading warranty term offered on the N-Type range — combined with a 12-year material and workmanship warranty. This warranty package meets the requirements of:

• Commercial project finance and PPA structuring
• Utility-scale procurement standards
• Institutional investment frameworks
• Long-term operations and maintenance contracts

For wholesale solar panels purchased at pallet scale for large commercial or mixed residential-commercial projects, the 30-year warranty provides the performance assurance baseline that sophisticated buyers demand.

Certifications

Electrical Performance

At 52.35V open circuit voltage, the SGN-590-BDG1 supports long string configurations with 1500V system architecture. The 44.40V maximum power voltage is compatible with standard commercial and residential string inverter platforms across all major manufacturers.

These are big solar panels — 89.69 × 44.65 inches and 69.45 lbs each. Two-person installation with appropriate mechanical assistance is recommended for rooftop applications. Ground-mount installations are well-suited to the large format.

Pallet Details

At 18,290W of peak capacity per shipment, this pallet of solar panels delivers more total kW than any other pallet format in the range. LTL freight delivery is required — confirm site access and offloading capability before ordering.

FAQ

What makes the SGN-590-BDG1 the top-specification sungold solar panel? At 590W per panel, the SGN-590-BDG1 is the highest-output Sungold solar panel available at wholesale pallet pricing. N-Type bifacial architecture, 144-cell large-format construction, 30-year linear power warranty and ETL UL61730 + ISO certification combine the highest per-panel output with the strongest warranty and compliance specification in the range — making it the logical choice for commercial projects prioritising output density and long-term performance assurance.

How does 18,290W from one pallet of solar panels compare? At 18,290W from 31 panels, this pallet of solar panels delivers more total capacity than any other pallet in the range. Compared to the 440W pallet at 13,640W, the SGN-590-BDG1 pallet provides an additional 4,650W from the same panel count — reducing the number of pallets required for a given system size and directly reducing installation labour and balance-of-system costs.

Why choose bulk solar panels at 590W over lower-wattage options? Bulk solar panels at 590W per panel reduce the total panel count required for any given system size. Fewer panels means less installation labour, fewer mounting components, shorter cable runs and reduced combiner box inputs — collectively reducing balance-of-system costs that can represent 30–50% of total project cost for commercial arrays. The per-kW economics of high-wattage panels are consistently superior to equivalent-total-output installations using smaller panels.

What is solar panel wholesale pricing for the SGN-590-BDG1? Solar panel wholesale pricing for the SGN-590-BDG1 is available at full pallet format — 31 panels per pallet. The pallet price shown above divided by 31 panels provides the effective per-panel wholesale rate. This N-Type bifacial specification at 590W represents competitive pricing for this technology class and certification level.

Are these solar powered systems for homes appropriate at this wattage? Yes — solar powered systems for homes using 590W panels require fewer panels to meet household energy needs, which can be advantageous for homes with limited roof space or where minimising visible panel count is a design priority. For large homes, luxury residential projects and whole house solar panels installations targeting net-zero or positive energy outcomes, the SGN-590-BDG1’s per-panel output density makes it an efficient choice.
