Product Description

This two-pack of Renogy 590W N-Type bifacial monocrystalline panels delivers 1,180 watts of front-side power — a compact, high-output starting point for an off-grid cabin, shed, or ground-mount system. The bifacial glass design also collects light reflected onto the back 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

Two 590W panels suit a weekend cabin, a well pump or gate system, a shed workshop, or the first phase of a larger array you plan to grow. If you want maximum wattage from just two mounting positions, this is the pack to start with.

Key Features

1,180W front-side output: two 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. The lineup — panels, charge controllers, batteries, inverters — is designed to work together and documented with published datasheets.

Sizing & System Fit

Two panels cover about 56 sq ft. On a 24V battery bank, 1,180W works out to roughly 41A of charge current — a 60A-class MPPT controller with room to grow. On a 48V bank it's about 20A. Wired in series the pair produces about 105V open-circuit; in parallel, 52.63V at up to 27A of operating current — check your controller's PV voltage and current limits either way, with cold-weather margin on voltage. For storage, a Renogy Core 300Ah LiFePO4 battery (or two in series for 24V) is a well-matched bank for this array's daily output.

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, so full manufacturer coverage applies. Call us at (302) 496-3554 with sizing or warranty questions.

Shipping

These are large-format panels (89.7 x 44.6 in, 58.4 lb each) and typically ship palletized via LTL freight. Inspect both panels before signing the delivery receipt and note any damage with the driver — this protects your claim.

Frequently Asked Questions

How do I get the bifacial gain from just two panels?

Mount them where light can reach the back: an elevated ground mount over gravel, concrete, or snow, or a tilt mount on a flat roof. Flush-mounted on a shingle roof, they perform as strong 590W monofacial panels — the rear side needs reflected light to contribute. The up-to-30% figure is Renogy's, under favorable rear-side reflection.

What size charge controller do I need?

On 24V, plan for a 60A-class MPPT controller (about 41A of charging at full output, plus headroom). On 48V, a 30A-class unit is comfortable. On 12V, 1,180W exceeds what a single common 60A controller can pass — consider 24V for this pack.

Series or parallel for two panels?

Series (about 105V Voc) keeps current low and wire small — check your controller's PV input limit with cold-weather margin. Parallel keeps voltage at 52.63V and doubles current, which tolerates partial shade on one panel better.

Can I add more 590W panels later?

Yes — this is a common starter quantity. Keep future strings the same length as your existing one, or land new strings on a separate MPPT input.

Will these work with my existing 12V panels?

Not in the same string or parallel group — the voltage difference is too large. Run each panel type on its own charge controller into the same battery bank instead.

How big are they, really?

Each panel is 89.7 x 44.6 in — nearly 7.5 ft tall — and 58.4 lb. Plan mounting locations and a helper accordingly.
