The 9 busbar design helps compensate by reducing internal resistance. Owner reviews note that the panel arrives well-packaged and the frame feels sturdy.
However, if you have limited roof space or need maximum power per square foot, you may be better served by a monocrystalline panel. This panel is best for those with ample roof area and a tight budget. It is not ideal for full-time off-grid living where every watt counts.
- 9 busbar technology improves energy capture
- Corrosion-resistant aluminum frame with 1.2mm tempered glass
- Pre-drilled holes for fast mounting
Pros: Very affordable for a 100W panel; Good build quality for the price
Cons: Lower efficiency than monocrystalline panels
3. ECO-WORTHY 120W Flexible Solar Panel: Best Flexible
The ECO-WORTHY 120W Flexible panel stands out for its ease of installation on curved caravan roofs. Based on owner feedback, the ability to bend up to 30 degrees makes it a popular choice for owners of teardrop trailers or vans with complex rooflines. At just over 5 lbs, it adds negligible weight. The monocrystalline cells are efficient for a flexible panel, though not as efficient as rigid panels.
However, flexible panels generally have a shorter lifespan than rigid ones due to heat buildup and potential delamination. Several owners report a drop in output after a couple of years. If you can mount a rigid panel, we recommend doing so for longevity. This panel is best for those who prioritize weight savings and easy installation over maximum durability.
- Ultra-thin and lightweight at only 5.3 lbs
- Can be bent to a 30-degree curve for non-flat roofs
- Pre-installed MC4 connectors for easy hookup
Pros: Very easy to install on curved surfaces; Lightweight, no drilling required if using adhesive
Cons: Lower durability than rigid panels, may degrade faster

Frequently Asked Questions
What size solar panel do I need for my caravan?
The size depends on your daily energy consumption. As a rule of thumb, a 100W panel can generate about 300-400 Wh per day in good sun, which is enough for lights, phone charging, and a small fridge. For larger loads like a microwave or air conditioner, consider 200W or more. We recommend calculating your daily amp-hour usage and sizing your panel to produce at least 1.5 times that amount to account for cloudy days.
Should I choose a rigid or flexible solar panel for my caravan?
Rigid panels are more durable and efficient, with longer lifespans, but they are heavier and require flat mounting. Flexible panels are lightweight and can be mounted on curved roofs, but they are less durable and may degrade faster. For permanent installations on standard caravan roofs, rigid panels are generally recommended. For curved or weight-sensitive setups, flexible panels are a viable alternative.
Do I need a charge controller with my solar panel?
Yes, a charge controller is essential to regulate the voltage and current from the solar panel to prevent overcharging your battery. PWM controllers are budget-friendly and work well for smaller systems, while MPPT controllers are more efficient and better for larger setups. Most kits include a controller, but if you buy a panel separately, you will need to purchase one.
Can I install a caravan solar panel myself?
Yes, many caravan owners install solar panels themselves. Most panels come with pre-drilled holes and MC4 connectors for easy wiring. Basic tools like a drill, screwdriver, and sealant are usually sufficient. However, if you are not comfortable working with electrical systems, or if you need to drill through the roof, professional installation is recommended to avoid leaks or damage.
How do I mount a solar panel on a caravan roof?
Rigid panels are typically mounted using brackets that attach to the roof with screws and sealant. Flexible panels can be adhered with strong adhesive or mounted using grommets and screws. Always ensure the mounting is secure and waterproof. Use a sealant around any holes to prevent leaks. It is also important to leave a small gap for airflow under the panel to help with cooling.
