Lensun 480W(2x240w) Full Black Flexible Solar Panel for Roof Tent

This 240W flexible solar panel with LONGi BC (Back Contact) technology delivers up to 25.8% efficiency and a sleek all-black design, making it ideal for RVs, campers, boats, and roof tents.

Ultra-thin and lightweight, just 2.5mm (0.1'') thick and 3.7kg (8.2 lbs) —about 30% the weight of traditional glass panels. Installs fast with adhesive or VHB tape, with no roof mods or reinforcements needed, so you stay light, low-profile, and adventure-ready.

Optional plug-and-play 40A waterproof MPPT controller—pre-wired with fuses and connectors, featuring smart protection (reverse polarity, overcharge) and compatibility with sealed, AGM, gel, flooded, and lithium batteries.

We also support a custom logo with low MOQ. Submit your request here: https://lensunsolar.com/pages/customized 

LONGi Back Contact Solar Cell – Kdfsey Advantages

1. Higher Efficiency (Up to 25.8%): Front-grid-free design lets more sunlight hit the cell surface, delivering up to 25.8% efficiency and up to 10% more power than standard PERC cells in low light.
2. Better Performance in Shade: Produces over 20% more power than conventional monocrystalline cells when partially shaded by roof racks, gear, or obstacles.
3. Stable & Safer Output: Maintains steady power when blocked by bird droppings or leaves, avoiding sudden drops and hot spots common in traditional panels.
4. Built for Extreme Conditions: Operates reliably from -40°F to 185°F (-40°C to 85°C), with a 30-year lifespan and 20% less power loss at high temperatures than PERC cells.
5. Clean, All-Black Design: All contacts are on the back, creating a smooth, grid-free front surface with a sleek, modern look.

Feature

1. 9-Layer Monolithic Lamination: Seamless 9-material encapsulation delivers unmatched resilience against vibration, extreme temperatures, and harsh outdoor abuse—ideal for off-road and rugged environments.
2. Aerospace-Grade Window Film: Dual layers of aircraft-window composite provide superior UV, impact, and microcrack resistance—protecting cells from hail, heavy snow, and high winds for long-term reliability.
3. BC (Back Contact) Solar Cell: No front gridlines. Efficiency up to 25.8%. Without metal lines on the front, more sunlight hits the cell directly, increasing the amount of electricity generated and demonstrating an average power output increase of up to 10 percent over PERC products in typical scenarios.
4. Premium EFTE Film: This film offers superior light transmittance and is heat, corrosion, and UV resistant. It also has self-cleaning abilities, ensuring optimal performance day after day.
5. Shade Tolerant: Twin array design allows continued performance even with shading by trees or debris.
6. Ultra-thin: At only 3mm/0.12 thick, our solar panel is powerful, waterproof, lightweight, durable, and highly resistant to the harsh operating conditions of a marine environment.
7. Lightweight: Weighs just ~30% of a glass-panel equivalent—ideal for maximizing power without hurting fuel economy or raising your vehicle's center of gravity.
8. Installation: This can be fixed by structural adhesive, zip ties, or velcro, and can be installed without costly structural roof reinforcements.
9. Optional plug-and-play 40A waterproof MPPT controller—pre-wired with fuses and connectors, featuring smart protection (reverse polarity, overcharge) and compatibility with sealed, AGM, Gel, and lithium batteries.
