400W Folding Solar Panels Introduction
The 400W folding solar panels open into a high-efficiency array built with monocrystalline cells and durable ETFE coating. A streamlined hinge and kickstand allow setup in seconds and fold flat for compact carry. Advanced heat-venting keeps output steady even under intense sunlight.
400W Folding Portable Solar Panels Price
The price of a 400W folding solar panel is around $170. This is the price without shipping. Please contact us for a discounted price for delivery to your door. Because it is a factory-direct quote, our quote varies with the price of raw materials for solar panels.

FAQ
1. Can I stick Velcro tape on the back of a 400W folding panel?
Yes, but avoid the battery cell area and attach it to the edge fabric or ETFE backing to prevent obstruction of heat dissipation. The adhesive strength of Velcro decreases at high temperatures, so the backing adhesive should be replaced regularly.
2. Does a 400W folding solar panel need grounding?
Most portable setups do not require it. However, in humid or thunderstorm conditions, it is recommended to connect the metal holes on the plate frame to the vehicle body or ground with a wire to discharge static electricity.
3. How should I store a 400W folding panel long-term?
Keep it fully unfolded in a cool, dry place away from direct sun; if space is tight, fold loosely and wrap in a breathable bag to prevent moisture pockets. Recharge the solar panel every three months to avoid deep discharge of any internal bypass diodes.
4. Can I use a 400W and a 300W folding solar panel together?
You can if both share the same nominal voltage and are wired in parallel, but the larger solar panel will be throttled to the smaller one’s current limit, wasting up to 100W. For best yield, pair identical models or add a second controller to manage each solar panel independently.
