Bifacial Solar Module

Bifacial Solar Module Collection: Panels and Kits That Use Both Sides

A bifacial solar module has cells that produce from the front face and from the rear, so light bouncing off snow, gravel, a white roof membrane or a concrete pad adds to the output of the same footprint. In this collection the format ranges from a 6.2 lb folding panel you carry to a campsite to 31 rigid 590W modules feeding a 24kW off-grid home. The extra rear-side gain matters most when panels are mounted with space behind them and over a bright surface; it matters least when they lie flat on a dark asphalt roof.

The collection holds 20 products from Sungold Power and Anker, from about $250 for a single 100W portable panel to $24,950 for a complete 24kW off-grid kit with 61.44kWh of storage.

How to choose a bifacial module

• Portable or fixed. If the panel travels with a power station, a folding unit is the right shape. The Anker SOLIX PS200 Bifacial 200W Portable Solar Panel weighs 10.6 lb, carries an IP68 rating and gains up to 10% from its rear face. For a roof or ground mount, rigid 450W or 590W modules in the Sungold Power kits are the correct choice.
• Wattage per module. Bigger modules mean fewer racking points. The Sungold Power 560W 48V Bifacial N-Type Solar Panels Kit starts at from $980 and is sold in kit sizes for people building their own 48V array.
• Panel alone or full system. A bifacial pv module is only one line item in a home system. The Sungold Power 12kW Off-Grid Solar Kit with 16 x 450W Bifacial Panels bundles 7,200W of PV, a 12kW 120/240V inverter and 20.48kWh of CoreX 5 Pro battery for from $9,990, so nothing needs to be matched by hand.
• Grid-tied or off-grid. If you keep a utility connection, the hybrid kits (SGS12K-PM1-450 with 9,000W of PV and 16.07kWh, SGS12K-PM3-590 with 10,620W and 48.21kWh) are built for that. The FR series kits are off-grid designs.

Setup and usage tips

• Give the rear face something to see. Ground mounts over light gravel, a pale roof or snow deliver the rear gain; a bifacial module laid flat on dark shingles behaves like a standard one.
• Leave an air gap. Rigid modules mounted with clearance behind them run cooler and let reflected light reach the back.
• Prop up the folding panels. The PS100 and PS200 gain from the rear only when light can get under them, so use the stand rather than laying them on the grass.
• Match the kit to the load, not the roof. Use the Solar Kit Calculator with your appliance list and ZIP code to see whether 7,200W or 14,400W of PV fits your daily consumption.
• When browsing solar modules for sale for a DIY build, plan the 48V battery and inverter at the same time; the 560W kit assumes you have those.

Frequently asked questions

How much extra power does a bifacial module produce? It depends on the surface below and the mounting. Anker states up to 10% more for its folding panels; Sungold Power states up to 30% more for its rigid N-type modules over reflective ground. Expect the low end on a roof.

Can I use a bifacial solar module with a portable power station? Yes. The PS100 and PS200 are designed for Anker SOLIX stations and ship bundled with the C1000 Gen 2 and C2000 Gen 2. Check your station's solar input limit before adding a second panel.

Do the rigid kits include the inverter and battery? The FR and SGS Sungold Power kits do, with capacities from 16.07kWh to 61.44kWh. The 560W panel kit is panels only.

Every solar module and kit here ships free to the mainland US from brand partner warehouses, usually within a few business days, with 30-day returns. Call us if you want help matching panel count to your roof or battery.
