GRECELL 200W Portable Solar Panel Foldable ETFE Charger — 23.5% Efficiency, MPPT & Carry Briefcase

The GRECELL 200W Portable Solar Panel is a foldable ETFE-chassis charger that delivers up to 23.5% conversion efficiency for reliable off-grid power.

This compact, briefcase-style solar array combines premium monocrystalline cells, ETFE lamination and a reinforced carry design to bring near-stationary solar performance to camping, RVing and emergency backup. Built-in features — including an MPPT charge controller, multiple output connectors and a protective waterproof cable pouch — are intended to speed setup, protect the electronics and make effective use of available sunlight whether you’re topping off a portable power station or charging a 12V battery directly.

How much power and efficiency does this panel deliver?

This 200W panel uses advanced monocrystalline silicon with a 6-layer ETFE laminate that boosts light transmission and cell performance. With a rated conversion efficiency of up to 23.5%, it harvests more energy per square foot than many standard portable panels, improving charge speed in variable light.

• Peak output: 200 watts under ideal conditions
• Conversion: up to 23.5% efficiency for higher energy yield
• Light transmittance: ~97% ETFE surface lets more light reach cells
• Improved low-light performance vs typical polycrystalline panels

What connectivity and charging options are available?

The GRECELL solar charger includes an MC4-to-4-in-1 cable that supports common power station input types and can be used with an optional charge controller or alligator clips to charge 12V batteries. This makes it compatible with many popular brands and battery chemistries for flexible deployment.

• Included: MC4 to XT60, Anderson, DC7909 and aviation connectors
• Works with most portable power stations, including Jackery and GRECELL models
• Can charge 12V AGM, Gel, LiFePO4 and Lithium-ion batteries (with correct controller)
• Supports series/parallel connections for system expansion

How easy is it to set up and use in the field?

Designed for quick deployment, the panel unfolds and stands using four adjustable kickstands so you can angle it toward the sun without tools. Reinforced grommets and a waterproof cable bag simplify mounting and cable management, letting you get power running in under a minute.

• Four built-in adjustable kickstands for rapid tilt adjustment
• Four reinforced corner grommets for secure mounting to tents, RVs or racks
• Built-in dual-zip waterproof cable bag stores cables and small accessories
• Folds into a compact briefcase with handle and locking clips for transport

How durable and weather-resistant is the panel?

The exterior combines ETFE-coated cells and a rugged 840D Oxford cloth backing to resist scratches, splashes and abrasion during travel. With an IP65 rating it’s built to withstand dust and water spray, but it should not be left submerged or exposed to heavy prolonged rain for optimal longevity.

• IP65 protection: dust-tight and water-spray resistant
• ETFE layer resists scratches and improves light transmission
• 840D Oxford cloth backing for tear and abrasion resistance
• Compact weight: 17.9 lbs; folded dimensions for easy storage

Who is this for? The GRECELL 200W Foldable Solar Panel is aimed at campers, RV owners, overlanders and homeowners needing a portable, higher-efficiency charging solution for power stations and 12V batteries. It suits users who want faster charging than typical polycrystalline chargers, straightforward compatibility with mainstream portable power stations, and a durable, transportable briefcase design that fits in vehicle storage or a gear closet.
