- Weight - 3.21 kg
- Wattage - 400W
- Special Feature - Flexible
Next we have the ECO-WORTHY 400W Flexible Solar Panel. It’s currently selling for £250/$338 on Amazon.
Each panel uses N-type monocrystalline cells with an 18-busbar design, offering a stated conversion efficiency of up to 25%. ECO-WORTHY also uses an ETFE surface with over 95% light transmittance, while a built-in blocking diode helps prevent reverse current from the battery during low-light conditions or at night.
Rather than a conventional folding suitcase, these panels use an ultra-thin 2.5–3mm flexible construction. Each 200W panel weighs around 3.21kg and includes six pre-drilled mounting points, making the system particularly suitable for semi-permanent installation on balconies, motorhomes, caravans, boats and other suitable surfaces.
That design does mean it’s somewhat different from the other portable panels in this comparison. It’s less focused on being repeatedly folded away and carried around, but the combination of 400W output, low weight and flexible mounting makes it an appealing option where the panels can remain installed or be set up for longer periods.
Overall, the ECO-WORTHY kit is best suited to users who prioritise higher solar output and flexible installation over suitcase-style portability. For a substantial home backup battery or power station capable of accepting a high solar input, its 400W capacity provides much greater charging potential than smaller portable panels.

- Dimensions - 164 x 88 x 3.5 cm
- Weight - 14.9 kg
- Wattage - 640W
- Special Feature - 10-Year Warranty
Another high-quality solar panel is the Renogy 640W Solar Panels. It’s currently selling for £340/$460 on Amazon.
For users looking for substantially more solar capacity, the Renogy 640W Solar Panel Kit combines two 320W monocrystalline panels. With 640W of rated output, it’s much better suited to larger home backup systems than the lower-powered portable options in this comparison.
The panels use N-type solar cells with an 18-busbar design, with Renogy claiming cell efficiency of up to 25%. The design is also intended to improve current collection and reduce the risk of hot spots, while maintaining better performance in higher temperatures.
Unlike a foldable portable panel, this is a more substantial rigid solar setup. Each panel measures 164 × 88 × 3.5cm and weighs 14.9kg, so it’s better suited to a semi-permanent or permanent installation than something you’ll regularly unpack during a power cut.
Durability is one of its strengths. Renogy specifies IP68 protection, tempered glass and corrosion-resistant aluminium framing for exposure to rain, snow and heat. The panels also come with a 10-year materials and workmanship warranty alongside a 25-year 80% output warranty.
Overall, the Renogy 640W kit is the better choice for a higher-capacity home backup installation where maximum portability isn’t important. Its significantly greater output makes it particularly appealing for larger battery systems, provided your charge controller or power station can accept the panel configuration and solar input.

FAQs
For basic backup of phones, routers and small electronics, 100–200W can be enough. For larger power stations or appliances, 200–400W+ is more practical. The best size depends on your battery capacity, solar input limit and how quickly you want to recharge.
Not directly in most cases. Portable panels are normally used to recharge a portable power station or home battery, which then powers your devices and appliances. Larger solar-and-battery systems can support more of the home.
No. You need to check the power station’s maximum solar input, voltage range, current limit and connector type before connecting a panel. An adapter alone does not guarantee compatibility.
Yes, but output can fall significantly in poor weather. That makes panel capacity and battery size more important if you want a reliable backup setup in the UK.
