Bifacial N-Type Power for Serious Off-Grid Builds

The SunGoldPower 590W Bifacial N-Type Monocrystalline Solar Panel is engineered for large-scale off-grid arrays where every watt matters. By capturing sunlight on both the front and rear sides, this panel significantly boosts your total energy yield without expanding your footprint. The dual-glass, weatherproof enclosure protects the N-Type cells from moisture and UV degradation, delivering stable output in low-light and extreme conditions. Compatible with standard racking and modern inverters, this field-tested module maximizes power density to keep your grid-independent system running at full capacity.

More Watts Per Panel Means Fewer Panels to Buy and Ship

More Watts Per Panel Means Fewer Panels to Buy and Ship

Most underperforming solar installations share the same root cause: panels that never hit their rated output in real-world conditions. You end up buying more panels, more racking, and more labor just to compensate for weak energy production. The SunGoldPower 590W bifacial panel eliminates that problem at the source. By generating power from both the front and rear faces, it delivers measurably higher energy yield per installed panel — especially over reflective surfaces like concrete or gravel. At Off Grid Vault, we only carry panels we would install on our own cabins. Every component we sell is pre-vetted for real-world performance, so your system produces what the datasheet promises.

N-Type Cells and Dual-Glass Built to Survive Decades Outside

N-Type Cells and Dual-Glass Built to Survive Decades Outside

N-Type monocrystalline cells outperform standard P-Type technology in two critical ways: they degrade slower over time and they maintain higher efficiency in low-light conditions — mornings, evenings, and overcast days when off-grid systems need every available watt. Paired with a dual-glass structure that replaces the traditional polymer backsheet, this panel resists moisture ingress, UV degradation, and thermal cycling far better than conventional builds. The result is a module that holds its output rating season after season. With 144 cells across a 44.40Vmp operating voltage, this panel integrates cleanly with modern MPPT charge controllers and high-voltage string configurations up to 1500V.

Engineered for Ground Mounts, Carports, and High-Gain Setups

Engineered for Ground Mounts, Carports, and High-Gain Setups

Bifacial panels reach their full potential when installed with available behind them and a reflective surface below. That makes this 590W module the right fit for ground-mount arrays, carport structures, pergolas, and any elevated installation where rear-side light capture is possible. At 89.69 by 44.65 inches and 69.45 lbs, the form factor suits standard railing and clamp systems without requiring specialized mounting hardware. The 12 AWG output cables ship at one foot per lead, ready for your preferred extension or combiner box wiring. UL61730 certified by ETL, this panel meets the safety and compliance standards that serious off-grid builders require before investing in a multi-panel array.

★★★★★
“Mounted eight of these on a ground rack over white gravel at my homestead in northern Arizona. The bifacial gain is noticeable — I am seeing 12 to 15 percent more daily production compared to my old monofacial panels of similar wattage. The dual-glass build feels off-grid proven, and the Vmp works cleanly with my EG4 MPPT controller. Solid addition to my self-reliant setup.”

Frequently Asked Questions

At $821.95 for 590W rated output, the base cost is approximately $1.39 per watt. However, bifacial panels typically generate 5 to 25 percent additional energy from the rear side depending on mounting height and surface reflectivity. When you factor in that real-world gain, the effective cost per watt drops further. For off-grid systems where every watt reduces generator runtime or battery depth of discharge, that surplus production has compounding value over a 12-year warranty period.
Off Grid Vault is an authorized dealer. Warranty claims are handled directly through us, not through a third-party ticket queue. The SunGoldPower 590W panel carries a 12-year limited warranty backed by ETL certification to UL61730 standards. If a panel underperforms within that period, you contact us and we manage the process. That is the difference between buying from a curated off-grid specialist and pulling a panel off a generic marketplace listing with no after-offer accountability.
With a Vmp of 44.40V and Imp of 13.29A, this panel is compatible with most modern MPPT charge controllers that accept the resulting string voltage and current. The 1500V maximum system voltage rating gives you flexibility in series string sizing for larger arrays. If you want confirmation for your specific setup, Off Grid Vault offers a free system design consultation. Tell us your controller, inverter, and target daily kWh consumption, and we will verify compatibility before you purchase.
This panel ships free on all orders, including LTL freight for multi-panel quantities. Lead times vary based on your selected quantity and current warehouse stock. We do not use fake countdown timers or fabricated scarcity claims. If you need a specific delivery window for your build timeline, contact us before ordering and we will give you an honest estimate based on actual inventory. Off Grid Vault treats your build schedule with the same seriousness you do.
N-Type monocrystalline cells use phosphorus doping instead of boron, which eliminates light-induced degradation that plagues P-Type cells over time. N-Type cells also maintain higher efficiency at elevated temperatures and in low-light conditions. For an off-grid system that needs to produce reliably across seasons and weather patterns, N-Type technology means slower annual degradation and more consistent daily output. The dual-glass construction on this SunGoldPower panel adds further protection against the environmental stresses that cause early failure in conventional backsheet designs.
Off Grid Vault offers a 30-day performance guarantee on uninstalled products in original packaging. If the panel arrives with shipping damage or does not perform to its rated specifications under test conditions, contact us and we will make it right. Beyond the 30-day window, the 12-year limited warranty covers manufacturing defects and performance degradation. Because we are an authorized dealer, warranty claims go through us directly — not to a manufacturer support line that puts you on hold.
