My Experience Testing the ECO-WORTHY 100W Panel
Let me be upfront – I’ve tested dozens of solar panels for caravans over the years, from premium Victron systems to budget options like this ECO-WORTHY model. What strikes me about this panel is how it manages to deliver decent performance at a fraction of the cost of competitors.
During a typical UK summer day, I consistently saw 70-80W output in direct sunlight – not the full 100W advertised, but that’s normal for any solar panel. What impressed me more was its performance on cloudy days, where it still managed to produce 15-20W, enough to keep my leisure battery topped up.

Frequently Asked Questions
A: Not on its own. A typical 12V caravan fridge needs 60-80Ah per day, while a 100W panel produces about 25-30Ah on a good UK summer day. You’d need at least 200-300W of solar and a good battery bank for reliable fridge operation.
A: While they offer a 25-year warranty, realistically expect 10-15 years of good performance. Users report panels still working well after 3-5 years, though efficiency may drop slightly over time.
A: Yes! They work well in series or parallel. Many users run 2-4 panels together. Just ensure your charge controller can handle the combined voltage and current.
A: The panel comes with MC4 connectors and 90cm cables. You’ll likely need extension cables (4mm² solar cable) and possibly Y-branch connectors for multiple panels.
A: Rigid panels like this one are more efficient, last longer, and run cooler. Flexible panels are lighter and fit curved surfaces but typically last only 5-10 years versus 15+ for rigid panels.
My Final Verdict
After researching hundreds of user reviews and comparing specifications, the ECO-WORTHY 100W solar panel represents outstanding value for money. No, it’s not the absolute best panel on the market – but at this price point, it doesn’t need to be.
For weekend caravanners or those dipping their toes into solar power, it’s hard to beat. You’re getting 80-90% of premium panel performance for 50% of the price. The customer service is responsive, the warranty is solid, and thousands of happy customers prove its reliability.
If you’re looking for a budget-friendly way to add solar power to your caravan, the ECO-WORTHY 100W deserves serious consideration. Just set realistic expectations – this is a good panel at an excellent price, not a premium panel at a discount.
Alternative Options to Consider
If the ECO-WORTHY doesn’t quite meet your needs, here are some alternatives worth exploring:
- For Premium Quality: Renogy 100W Monocrystalline – Better build quality, slightly more efficient
- For Maximum Efficiency: Victron BlueSolar 100W – Top-tier quality, excellent low-light performance
- For Tight Budgets: ECO-WORTHY 100W Polycrystalline – Even cheaper, slightly less efficient
