Renogy 590W N-Type Bifacial Solar Panels – 2-Pack or 4-Pack

Renogy 590W N-Type Bifacial Solar Panels – 2-Pack or 4-Pack

Choose a two-panel or four-panel package of full-size 590-watt Renogy N-Type bifacial modules. The 2-panel set provides 1,180 watts of total front-side nameplate capacity, while the 4-panel set provides 2,360 watts. These are built for serious fixed solar installations where high output per panel, dependable hot-weather performance, and long-term durability matter.

Current availability: The 2-panel set is temporarily out of stock. The 4-panel set is available to order.

Here is the honest version: these are not little portable suitcase panels. Each module is nearly 7.5 feet long and weighs 58.4 pounds, so plan the rack, handling, wiring, and charge equipment before they arrive. For a cabin, shop, farm, ground mount, or larger backup-power array, though, the big format can reduce the number of panels and connections needed to reach your target wattage.

Why These 590W Bifacial Panels Stand Out

• Flexible array sizing: 1,180W with the 2-panel set or 2,360W with the 4-panel set.
• N-Type monocrystalline cells: engineered for high conversion efficiency and reduced power loss in hot conditions.
• Bifacial energy production: the rear side can collect reflected light from bright roofs, gravel, concrete, snow, or other reflective surfaces.
• 22.8% module efficiency: strong output from the available panel footprint.
• 80% bifaciality factor: designed to make better use of rear-side irradiance when the installation allows light behind the module.
• 16-busbar cell design: improves current collection and supports reliable long-term operation.
• IP68 protection: built for permanent outdoor use in demanding environments.
• Long-term coverage: 10-year material and workmanship warranty plus a 25-year performance warranty.

Best Use Cases

• Off-grid cabins, workshops, barns, and remote properties
• Ground-mount solar arrays with good rear-side exposure
• Residential or commercial rooftop systems using compatible racking
• Agricultural and farm power systems
• Large battery banks and whole-home backup systems with a compatible solar charge controller or hybrid inverter
• Cold or snowy locations where reflected light can improve bifacial production
• Hot climates where the panel's low temperature coefficient helps protect output

Bifacial Output: What to Expect

The 590W rating is the front-side STC rating of each panel. Renogy states that favorable rear-side conditions can add as much as 177W per module, but real bifacial gain depends on ground reflectivity, mounting height, tilt, spacing, shade, temperature, and weather. Do not size an inverter or charge controller around a perfect-condition marketing number. Use the electrical ratings below and leave the safety margin required by the equipment manufacturer and electrical code.

Full Specifications

Electrical specifications below are per panel unless noted otherwise.

What's Included

• 2 or 4 × Renogy 590W N-Type bifacial monocrystalline solar panels, based on the selected pack size

Mounting hardware, solar cable extensions, overcurrent protection, combiner equipment, charge controller, and inverter are not listed as included and should be selected for the installation separately.

Important Compatibility Note

Match the array to your equipment by voltage and current—not wattage alone. Each panel has a 52.63V open-circuit voltage and 14.13A short-circuit current. Series and parallel wiring change the array voltage and current, and cold temperatures can increase open-circuit voltage. Confirm the planned string layout is within the solar input limits of your charge controller, inverter, or power station before connecting the panels. Permanent installations should follow applicable electrical and structural codes.

Warranty

• 10-year material and workmanship warranty
• 5-year performance level: 95% output
• 10-year performance level: 90% output
• 25-year performance level: 80% output

Frequently Asked Questions

Can I choose two or four 590W panels?

Yes. Use the Pack Size selector to choose either 2 Panels or 4 Panels. The 2-panel set provides 1,180W and the 4-panel set provides 2,360W of front-side nameplate capacity under standard test conditions. The 2-panel set is currently out of stock.

Can the panels produce more than 590W each?

The 590W rating is the front-side STC rating. The bifacial rear surface can add energy when reflected light reaches it, and Renogy cites up to 177W of additional rear-side contribution per panel under favorable conditions. Actual gain varies by installation and weather.

What is the difference between 25% cell efficiency and 22.8% module efficiency?

The 25% figure applies to the individual solar cells. The 22.8% figure measures the complete module, including spacing, frame, and other panel components. Module efficiency is the better number for comparing usable output by panel area.

Are these portable solar panels?

No. These are large, rigid modules intended for a properly engineered fixed or semi-permanent rack. Each panel weighs 58.4 pounds.

Will these panel packages work with my power station or inverter?

Possibly, but the answer depends on the equipment's solar input voltage, current, and wattage limits. Compare those limits with the panel Voc, Isc, Vmp, and Imp above, including cold-weather voltage rise and the planned series/parallel configuration.

Where do bifacial panels work best?

They perform best when the rear surface is elevated and exposed to reflected light. White membrane roofs, light gravel, concrete, snow, and open ground-mount structures can improve rear-side production compared with mounting the panel directly against a dark surface.

Is mounting hardware included?

No mounting hardware is listed as included with the selected panel package. Choose racking and fasteners rated for the module dimensions, weight, site wind load, and roof or ground-mount structure.

What warranty comes with the panels?

Renogy lists a 10-year material and workmanship warranty and a 25-year performance warranty, with stated output levels of 95% at 5 years, 90% at 10 years, and 80% at 25 years.
