When our supplier introduced a new high-output, flexible marine solar panel, I was initially skeptical. The specifications seemed almost too good to be true, so I decided to order some for testing—and I’m glad I did.
These panels are impressively built, with power generation that rivals our traditional rigid panels. Capable of flexing up to 30 degrees, they’re perfect for adapting to the curved surfaces commonly found on boats. The 100+ watt panels include a front-mounted electrical box (not pictured) that houses two blocking diodes for reliable performance, while the 50-watt model has one blocking diode. The base material is extremely durable, and each panel includes grommets for secure attachment.
I’ve tested these panels in various weather conditions to evaluate their output and shade tolerance. Below is a quick performance comparison of our three mid-range panels, tested lying flat at midday under mostly sunny conditions and measured with a meter:
| Flexible 100 watt (Monocrystalline) | Rigid 105 watt (Monocrystalline) | Rigid 100 watt (Polycrystalline) | |
|---|---|---|---|
| Short Circuit Current (Isc) | 5.48 amps | 5.50 amps | 5.26 amps |
| Open Circuit Voltage (Voc) | 19.2 volts | 19.7 volts | 20.5 volts |
| Computed Power | 105 watts | 108 watts | 108 watts |
