Flexible 20W 18V Solar Panel

The Crystalsolar panel is a lightweight monocrystalline module built to charge 12V batteries in mobile and off-grid settings. Its flexible glass-fibre construction allows mounting on curved surfaces such as RV roofs, boat decks or garden sheds. The package includes crocodile clips and a power cable for immediate connection.

Upgrade from rigid glass panels

Rigid framed panels cannot conform to curved roofs and add significant weight to portable setups. This 5 mm thin flexible sheet saves 579 g and fits irregular contours without drilling. The jump is worth it when installation space is limited, vibration resistance matters or the panel must be moved frequently between vehicles.

20W output with 17% conversion

At 18 V and 1.2 A the panel comfortably maintains leisure batteries, runs small water pumps, garden lights or venting fans in good sunlight. Output drops sharply in heavy cloud or when the surface overheats, so it cannot sustain high-draw inverters or charge large battery banks quickly. Buyers needing more than 20 W should combine multiple units.

Questions about this item

What are the panel dimensions and weight for mounting?

The panel measures 450 mm by 350 mm with a 5 mm thickness and weighs 579 g.

How do I connect the panel to a 12 V battery using the included parts?

Attach the supplied crocodile clips to the battery terminals, then plug the power cable into the panel junction box.

Does the monocrystalline silicon surface need periodic cleaning?

Yes, dust or debris on the glass-fibre laminate reduces the 17 % conversion rate, so wipe it clean when output drops.
