Callsun 200W Flexible Solar Panel Kit (2x100W) Ultra-Thin ETFE, Bendable for RVs & Vans

Callsun's 200W Flexible Solar Panel Kit is a two-panel, ultra-thin ETFE-covered flexible array (2×100W) built to conform to curved roofs and deliver reliable off-grid power for vehicles and small systems.

Designed for travelers, van-lifers, boaters and weekend campers, this lightweight flexible kit replaces bulky rigid modules with an all-black, low-profile solution. With ETFE top-sheathing and multi-layer construction, the panels resist yellowing and damage while remaining bendable for curved surfaces. Included cables, clear connection options, and a five-year warranty make setup straightforward whether you’re wiring a portable power station or expanding a small battery bank.

How well will these panels mount to curved roofs and odd surfaces?

These panels are engineered to flex up to roughly 240° so they can follow the contours of most RV roofs, teardrop trailers, and boat decks. Their ultra-lightweight construction reduces stress on adhesive mounts and prevents lifting at speed.

• Up to 240° bending capability for curved surfaces
• 0.1-inch thin profile lays almost flush for low clearance needs
• Weighs about half of comparable rigid panels for easier adhesive mounting

What durability and weather resistance can I expect from the ETFE construction?

ETFE offers superior weathering properties compared with standard PET laminates, guarding against yellowing and cracking over time. The panel’s multi-layer bonding and premium top coat improve resistance to hail and UV exposure, helping maintain output across seasons.

• ETFE top-sheath for long-term UV and yellowing resistance
• Multi-layer bonded construction for impact tolerance
• All-black face for discreet appearance and heat dispersion

How much energy can I realistically get from this 200W kit?

Under ideal sun conditions this 200W array can harvest up to about 1 kWh per day, making it a good match for charging portable power stations, running small appliances, or topping off a 12V/24V battery bank on weekends. Actual energy depends on location, tilt, shading and season.

• Rated as 2×100W panels — combined 200W peak capacity
• Up to ~1 kWh daily under optimal sun and orientation
• Supports series or parallel wiring to fit 12V or 24V systems

What comes in the kit and how is it wired to my system?

The package includes two 100W flexible panels, connection cables and a user manual to simplify installation. Panels are set up for straightforward series or parallel connections so you can configure voltage and current to match portable power stations or battery banks.

• Two Callsun 100W flexible panels (all-black finish)
• Connection cables and clear wiring options for series/parallel setups
• Industry-leading 5-year warranty and customer support

Who is this for? The Callsun 200W Flexible Solar Panel Kit is aimed at people who need a lightweight, low-profile solar option for curved or low-clearance installations — including van lifers, RV and boat owners, and weekend off-grid campers. It’s best for users who want easier installation and discreet appearance without the weight and rigidity of framed panels, and for those pairing panels with portable power stations or modest battery banks.
