Nature's Generator Rigid 440 Watt Bifacial Solar Panels (4 Pack), 1,760W N-Type TOPCon

The Nature's Generator Rigid 440W Bifacial Solar Panels (4 Pack) are 1,760W of full-size N-type TOPCon bifacial panels at 22.53% efficiency, built for permanent roof or ground mounting with Nature's Generator L3600 and L6000 systems. The back face also picks up light reflected off a light roof, gravel or snow.

Charge time (RPC estimate, full sun, panels at 75% of rating, about 330W each):

Each panel is 38.8V open-circuit. Nature's Generator pairs the 4-pack with an L3600 and Power Pod. Wire them in strings of two in series (77.6V open-circuit each), since three in series would exceed the L3600's limit of about 80V. Ask us to confirm the four-panel layout for your system before installing.

Size it for your own setup: pick your appliances, days off-grid and solar in the RPC Power Calculator, and it shows the in-stock stations and kits that fit.

Built with tempered glass, an anodized black aluminum frame and an IP68 junction box with MC4 connectors. At 67.8" × 44.6" and 54 lbs each, they need a permanent mount; mounting hardware and cables are sold separately.

Best for: L3600 systems with a Power Pod • Roof or ground mounts • Off-grid cabins and homesteads

Not the best fit if: you want portable panels or have a single station. These weigh 54 lbs each and mount permanently. For one L3600 or L6000, the 2-pack is enough to start.

Works with: L3600 power station • L3600 solar generator kit • L6000 power station • Universal solar panel mount

Frequently Asked Questions

How much power do 440W panels really make?
About 330W each in full midday sun, so roughly 6.6kWh over a good solar day for 4 panels.

How many can I wire in series?
On the L3600, two per string. Two in series reach 77.6V open-circuit; three would exceed the L3600's limit of about 80V. Panel voltage rises in cold weather, so ask us before installing where winters drop well below freezing.

Do they work with the L6000?
Yes, one panel per solar input, two panels per L6000. Don't wire them in series on the L6000; two in series exceed its 60V input limit.

Do they include a mount?
No. The Universal Solar Panel Mount holds two 440W panels and is sold separately.
