Two 200W bifacial modules use light from both sides, with JJN specifying rear-side gains of up to 30% on white reflective surfaces. That makes this 400W set especially relevant for a backyard location where reflective ground can be arranged beneath the panels rather than relying on front-side sunlight alone.

The compact 38.19-by-22.68-inch dimensions stated in the features support carrying and positioning the modules where ground conditions matter; the listing also describes setup as manageable by one person. Bifacial capture is tied to the surface: JJN gives approximate gains of 5–10% on grass and 15–25% on sand or gravel, compared with up to 30% on white reflective surfaces. The stated 2000Wh daily output is listing-specific, not a guarantee for every site.

Skip it if you cannot provide reflective ground and want high panel wattage; Livosun’s single 435W panel offers more rated capacity in one module.

Choose JJN when a compact bifacial pair can sit above reflective ground in a backyard or remote setup. Match expectations to the surface: the strongest stated rear-side gain requires white reflectivity, not ordinary grass.
