FlexoSun 165W Portable Solar Panel | TOPCon Technology| 26% efficiency | Teflon

Available early July The FlexoSun 165W is Flexopower's entry-level TOPCon solar panel — the natural successor to the Namib 150W. Built on TOPCon (Tunnel Oxide Passivated Contact) cell technology, it delivers ≥25.8% cell efficiency, IP67 waterproofing and a 5-year warranty — a full generation ahead of shingled ETFE construction. 165W of field-proven output in a compact tri-fold design that folds to 600 × 610 × 45mm. Connects directly to any Flexopower power station via a FlexoLink extension cable — no separate charge controller required. Panel in the sun. Park in the shade. Key Features TOPCon shingled solar cell technology — ≥25.8% cell efficiency, 16BB, 182.5 × 182.5mm cells IP67 rated — fully dustproof and waterproof. Built for real field conditions Compact tri-fold design — folds to 600 × 610 × 45mm. Fits behind a seat or in a drawer system Anderson SB50 50A connector — 4mm² lead wire, genuine Anderson connector Collapsible aluminium legs — angle the panel at 45° for improved harvest in winter and low sun Eyelet mounting points — secure the panel to a vehicle, roof rack or ground using pegs or rope 5-year warranty — the longest warranty in the Flexopower solar panel range Free delivery within South Africa Best Use Cases Weekend camping and bush travel — 2 to 4 days in camp with light to moderate loads Caravans and trailers Overlanding setups requiring a compact high-efficiency panel Park in the shade, panel in the sun strategy Buyers upgrading from legacy shingled panels Ambassador Rikus Truter's recommended panel — LekkerKampslekke, 309,000+ followers How to Use It Park in the shade. Put the panel in the sun. Connect the FlexoSun 165W directly to your Flexopower power station via a FlexoLink extension cable — no separate charge controller required. Alternatively, connect directly to a solar charge controller in front of a deep cycle battery for use in a conventional fixed solar system. Technical Specifications Rated output 165W Cell technology TOPCon shingled monocrystalline — ≥25.8% efficiency Open circuit voltage (Voc) 21.2V Max operating voltage (Vmp) 18.8V Short circuit current (Isc) 10.21A Operating current (Imp) 8.51A Max system voltage 100V IP rating IP67 Output tolerance ±5% Dimensions deployed 1,635 × 610 × 3mm Dimensions folded 600 × 610 × 45mm Connector Anderson SB50 50A — 4mm² lead wire Warranty 5 years What's in the Box 1 × FlexoSun 165W foldable solar panel — Anderson SB50 50A connector, unique serial number Frequently Asked Questions Do I need a charge controller? No — when connecting directly to a Flexopower power station via a FlexoLink cable, the power station's built-in MPPT controller manages the charge. If connecting to a conventional deep cycle battery, a separate solar charge controller is required. What is TOPCon technology? TOPCon (Tunnel Oxide Passivated Contact) is the latest generation of monocrystalline solar cell technology. It achieves higher efficiency than PERC and shingled ETFE panels by reducing electron recombination losses at the cell surface. The result is more watts per square metre and better performance in low-light conditions. Is the FlexoSun 165W waterproof? Yes. The FlexoSun 165W is IP67 rated — fully dustproof and waterproof to 1 metre submersion for 30 minutes. It is built for real field conditions including rain, dust and humidity. How does the FlexoSun 165W compare to the FlexoSun 260W? Both panels share the same TOPCon cell technology, IP67 rating, Anderson SB50 connector and 5-year warranty. The 165W uses a tri-fold design and is more compact, making it ideal for smaller setups or space-constrained vehicles. The 260W uses a four-panel fold and delivers 57% more power — suited to larger power stations and longer trips. What is the warranty? 5 years. The longest warranty in the Flexopower solar panel range. New generation. Higher efficiency. IP67. The FlexoSun 165W — where the FlexoSun range begins.
