AeternaSol 200W Bifacial Solar Panel 12V N-Type — Transparent Backsheet, IP68 Junction Box

The AeternaSol 200W bifacial solar panel is a compact, high-efficiency 12V module that captures sunlight on both faces to increase power output and durability for off-grid and auxiliary power systems.

Designed for applications from RVs and small cabins to ground-mounted arrays and hybrid systems, this 200-watt panel combines N-type A+ cells, an IP68-rated junction box, and robust construction. Its transparent backsheet lets reflected light contribute to generation, while full-weld 18-busbar cells and upgraded connectors and wiring focus on long-term performance and reliability.

How does bifacial technology increase energy production?

The transparent backsheet allows the panel to collect direct sunlight on the front and reflected or diffuse light on the rear, producing more energy than a single-sided module under the same conditions. Bifacial gains depend on surface reflectivity and mounting height but can boost output in many installations.

• Transparent backsheet captures ground-reflected light
• Up to ~30% additional yield on reflective surfaces
• Works effectively on racks, poles, or elevated installations
• Benefits scale with albedo and tilt angle

What makes the AeternaSol cells and wiring more reliable?

This panel uses N-type A+ monocrystalline cells with 18 full-weld busbars and silver-containing conductors to reduce microcracks and resist degradation. The included 11 AWG oxygen-free copper cable and UV-resistant jacket provide better conductivity and longer life than typical copper-clad aluminum alternatives.

• 25% cell efficiency rating with low initial degradation
• ≤1% first-year and ≤0.4% annual degradation rates expected
• 11 AWG oxygen-free copper wire rated for up to 25A
• UV-resistant cable jacket extends outdoor lifespan

Is the junction box and connector weatherproof for outdoor use?

Yes — the integrated junction box is IP68-rated and uses potting compound to prevent moisture ingress, reduce corrosion, and improve thermal management. The panel also ships with durable MC4-style connectors with galvanized copper pins and a robust PPO shell for secure, long-lasting electrical connections.

• IP68 potting prevents water and steam entry
• Improved heat dissipation minimizes thermal stress
• Galvanized copper MC4 pins resist corrosion
• Compatible PPO connector housing for reliable mating

How easy is installation and what mounting features are included?

The panel arrives with a corrosion-resistant aluminum alloy frame that is pre-drilled for fast mounting and sealed against air corrosion at the cell edges. The frame is lighter than comparable steel and keeps a polished appearance while supporting roof, rack, or ground installations.

• Pre-drilled mounting holes for common brackets
• Aluminum alloy frame resists rust and maintains finish
• Frame sealant protects cell edges from air exposure
• Compatible with standard racking and MC4 cabling

Who this panel is for: The AeternaSol 200W bifacial 12V panel suits homeowners, RV owners, tiny-home builders, and installers who want a compact, efficient module that extracts extra energy from reflective surfaces while offering enhanced wiring, connectors, and weatherproofing for long-term reliability. Choose this panel when you need a rugged, higher-yield option for off-grid arrays, portable systems, or supplementing larger installations where space or weight is limited.
