The Renogy 320W N-Type Monocrystalline Solar Panel 6-Pack delivers 25% cell efficiency, 22.2% module efficiency, and a 25-year linear power output warranty — in a frame 13.5% smaller and 17.2% lighter than traditional 320W panels.
The Renogy 6-Pack 320W N-Type Monocrystalline Solar Panel (SKU: RSP320DC-BKx6-US) delivers a combined 1,920 watts of rated solar capacity — enough to meaningfully power an off-grid cabin, large RV, tiny home, or commercial rooftop installation. Each panel uses advanced N-Type cell technology with 18 busbars (18BB) to achieve up to 25% cell efficiency and 22.2% module efficiency, outperforming conventional P-Type PERC panels in real-world heat, partial shading, and long-term output retention. Six of these panels replace an eighteen-panel 100W array, covering less roof area and requiring far fewer wiring connections — a leaner, more reliable installation from day one.
Every design decision in the RSP320DC — from the N-Type silicon to the 18-busbar grid — is engineered to extract more energy, hold it longer, and withstand more punishment than conventional panels.
N-Type monocrystalline cells convert up to 25% of incoming sunlight into electricity — outperforming standard P-Type and PERC designs and ensuring you get the most power possible from every inch of available roof area.
18 busbars shorten the electron path across each cell, minimizing resistive losses and distributing current collection to reduce localized heating. The result is more stable output in harsh weather and a longer effective lifespan compared to lower-busbar designs.
At 64.6 × 34.7 × 1.4 in and only 32.9 lbs each, the RSP320DC is 13.5% smaller and 17.2% lighter than traditional 320W panels — making six-panel installs more manageable on RV rooftops, cabin structures, and commercial buildings where structural load limits matter.
Renogy guarantees at least 95% of rated output at year 5, 90% at year 10, and 80% at year 25. A linear warranty means no sudden performance cliff — just a predictable, gradual decline you can plan around with confidence when sizing storage and loads.
An IP68-rated junction box, IP67-rated MC4 connectors, low-iron tempered glass, and a corrosion-resistant anodized aluminum frame protect every panel against dust, moisture, snow loads up to 5,400 Pa, and wind pressure up to 2,400 Pa.
With six panels producing a combined 1,920W, your array can generate approximately 9,600 Wh (9.6 kWh) per day based on 5 peak sun hours* — a meaningful generation base for powering appliances, lighting, refrigeration, and battery storage in a cabin, tiny home, or large RV.
Conventional P-Type panels lose a measurable percentage of their rated output as surface temperature rises — a real-world performance gap on sun-baked rooftops and south-facing cabin installations at peak summer. N-Type silicon is inherently resistant to light-induced degradation (LID), and the lower temperature coefficient means these panels maintain a higher proportion of their rated 320W in extreme heat compared to PERC alternatives. Paired with the 18-busbar layout's superior current distribution, the RSP320DC delivers consistently strong output across the widest possible range of operating conditions.
Eight pre-drilled mounting holes on the rear frame of each panel make installation straightforward with Renogy Z Brackets, Corner Brackets, Flat Roof Tilt Mounts, and Pole Mounts (all available separately). Pre-attached MC4 leads (male and female) on every panel allow series or parallel wiring directly into your charge controller. Six panels at this wattage replace an eighteen-panel 100W array — cutting the number of individual cable terminations and mounting points by two-thirds, and substantially reducing total installation time and hardware cost.

The six panels combined deliver 1,920W of rated capacity (6 × 320W) under Standard Test Conditions. Based on approximately 5 peak sun hours per day, this array can generate around 9,600 Wh (9.6 kWh) daily — a substantial generation base for off-grid cabins, large RVs, and residential backup systems. Actual output depends on your location, season, panel tilt angle, shading, and system losses.
Controller sizing depends on your wiring configuration and battery voltage. In a parallel 12V arrangement, six panels at ~8.92A Isc each produce a combined ~53.5A short-circuit current, requiring a controller rated for at least 60A. Wiring in series raises array voltage, reducing current proportionally. At 1,920W, Renogy strongly recommends an MPPT charge controller, which extracts significantly more power from the panel's voltage curve than a PWM controller — especially at this array size. Always verify your controller's maximum PV input voltage against the string Voc before wiring.
The N-Type RSP320DC is a meaningful upgrade over the older P-Type PERC RNG-320D. Highlights: cell efficiency rises from ≥22% to up to 25%; module efficiency improves from 19.2% to 22.2%; each panel weighs 32.9 lbs vs. 39.7 lbs (17.2% lighter); overall panel footprint shrinks by 13.5%; Voc increases from ~40.3V to 43.82V (critical for MPPT controller selection); and the material & workmanship warranty extends from 5 years to 10 years. N-Type cells also resist light-induced degradation (LID) better than P-Type and perform more reliably at high temperatures.
No mounting hardware is included. Each panel has 8 pre-drilled rear-frame holes compatible with Renogy Z Brackets, Corner Brackets, Flat Roof Tilt Mounts, and Pole Mounts, all available separately from Renogy. You will also need a charge controller, adapter kit, tray cables, and a battery bank to complete your system. None of these are included in this 6-pack.
Yes. The RSP320DC works with on-grid, off-grid, and hybrid solar configurations. For on-grid and hybrid installations, Renogy recommends engaging a licensed solar installer familiar with grid-tie equipment and local electrical codes, as these systems involve regulatory and safety requirements beyond the scope of panel selection alone.
Renogy recommends matching Open Circuit Voltage (Voc) within any series string for optimal performance. The N-Type RSP320DC has a Voc of 43.82V; the older PERC RNG-320D has a Voc of approximately 40.3V. Mixing these in the same string would reduce output to the lower panel's limit. If mixing brands is unavoidable, ensure Voc values match as closely as possible, and keep mismatched panels in separate strings feeding into a controller with multiple MPPT inputs.
Solar panel hardware installed in a qualifying residential solar system may be eligible for the federal Residential Clean Energy Credit (ITC), currently allowing up to 30% of qualifying system costs. Eligibility depends on your specific installation scenario, property type, and individual tax situation. Consult a qualified tax professional or visit the U.S. Department of Energy's official website for current eligibility guidance before claiming any credit.
No. Per Renogy's policy, solar panels rated above 250W must ship via LTL (less-than-truckload) freight and do not qualify for standard free shipping. Shipping charges will be calculated at checkout based on your delivery address. Deliveries to Alaska and Hawaii may incur additional surcharges.
The RSP320DC carries a 10-year material and workmanship warranty covering manufacturing defects, plus a 25-year linear power output warranty: Renogy guarantees ≥95% of rated output at year 5, ≥90% at year 10, and ≥80% at year 25. The linear structure means performance is guaranteed to decline gradually and predictably — not abruptly — giving you a reliable basis for long-term energy production planning. Purchasing through TrueStead Supply as an authorized Renogy dealer ensures your full warranty coverage is backed by the manufacturer.
