Renogy 4 PCS N-Type Bifacial 590W Monocrystalline Solar Panel

This four-pack of Renogy 590W N-Type bifacial monocrystalline panels builds a 2,360-watt front-side array — enough generation for a full-time cabin, a large RV or bus conversion with the roof to carry them, or the core of a growing ground-mount system. Bifacial glass construction also harvests light reflected onto the rear of each panel, producing up to 30% more power than comparable monofacial panels when mounted with rear-side exposure, per Renogy.

Who This Pack Is For

Four 590W panels fit builders who want serious daily production from a manageable panel count: off-grid cabins on 24V or 48V banks, workshop and barn systems, and ground mounts planned with room to expand. Fewer, larger panels mean fewer mounts, fewer connections, and less wiring.

Key Features

• 2,360W front-side output: four 590W panels rated at standard test conditions, per Renogy.
• Bifacial rear-side gain: 80% bifaciality factor; up to 30% more power (up to 177W extra per panel) with rear-side exposure, per Renogy.
• N-Type cell technology: 25% cell efficiency and 22.8% module efficiency, per Renogy.
• High-voltage-ready: 1500VDC max system voltage with a 30A max series fuse rating.
• IP68 junction box: with 12 AWG output cables, 66.9 in long, per Renogy's datasheet.
• Wide operating range: -40°F to 185°F.
• Tested to standards: EN IEC 61730 and EN IEC 61215; produced in an ISO 9001 certified facility, per Renogy.

Why Renogy

Renogy has built DIY-friendly off-grid power equipment since 2010, starting at Louisiana State University with support from the Louisiana Business and Technology Center. Its panels, charge controllers, batteries, and inverters are engineered to work as one system, with published datasheets behind every spec.

Specifications

Sizing & System Fit

Four panels need about 111 sq ft of roof or ground area. On a 48V battery bank, 2,360W is roughly 41A of charge current — comfortable for a 60A-class MPPT controller. On 24V it doubles to about 82A, which usually means splitting across two controllers. A 2S2P layout (two strings of two panels) runs about 105V open-circuit per string; verify your controller's PV limit with cold-weather margin. For the rest of the system, the Renogy REGO 3000W split-phase inverter-charger handles AC loads while a Renogy Pro S1 240Ah LiFePO4 battery bank stores the day's production.

Warranty & Support

Renogy warrants these panels for 10 years on materials and workmanship, with power output warranted to 95% of rated at 5 years, 90% at 10 years, and 80% at 25 years, per Renogy. OffGrid Horizon is a family-owned authorized Renogy dealer — full manufacturer coverage applies, and real people answer (302) 496-3554.

Shipping

Four-panel orders ship palletized via LTL freight. Each panel is 89.7 x 44.6 in and 58.4 lb — plan for help at delivery. Inspect all four panels before signing the delivery receipt and note any damage with the driver to protect your claim.

Frequently Asked Questions

What mounting gets me the bifacial bonus?

Elevated, open-backed mounting over a reflective surface: ground mounts above gravel, sand, or snow, or tilt legs on a flat roof. Flush-mounted panels produce front-side power only. Renogy's up-to-30% gain figure assumes favorable rear-side reflection.

What controller does a 2,360W array need?

On a 48V bank, a 60A-class MPPT controller covers the roughly 41A this array produces at full output. On 24V, plan on two controllers or a unit rated near 100A. Match string voltage to the controller's PV input window with cold-weather margin.

How should four panels be strung?

2S2P is the usual answer: two strings of two panels, about 105V Voc per string, paralleled at a combiner. All four in series (about 211V Voc) suits only controllers with high PV input limits.

Do these fit on an RV roof?

Each panel is 89.7 x 44.6 in, so four require about 111 sq ft of clear roof — realistic on large buses and toy haulers, tight on most travel trailers. Measure your usable roof area, including clearance around vents and ACs, before committing.

Will partial shade ruin the array's output?

Shade affects the series string it falls on. Running two strings on separate MPPT inputs, or keeping strings short, limits the loss to the shaded portion.

Can I mix these with different panels on one controller?

Avoid it — mismatched specs pull the whole input down to the weakest panel's performance. Separate controller inputs per panel type is the clean solution.
