Tested different models through two seasons, and the 400 watt solar panel showed the most resilience. The surface coating prevents salt residue from sticking, and the frame stays rigid through humidity swings. Efficiency barely shifts between bright sun and cloudy intervals, which says a lot for real-world use. Each panel delivers solid current with less temperature loss than most mid-range options. Not flashy marketing — just steady power that keeps running after the weather stops cooperating.
