SP50F Sunbeamsystems Standard surface
flexible panels are suitable for deck or canvas mounting.
SP = Standard surface a highly durable finish, designed to be walked on and has higher light transmission than glass.
For a tougher non-skid surface choose "Tough" surface panels.
50 = 50 Watts nominal power output
F = Flush wiring is a specialized flat profile wiring that allows fully flush deck mounting with invisisble wiring runs.
[Technical Note: the 'Flush' panels have no junction box fitted so where required these should be installed in the system wiring. Sunbeamsystems recommend a bypass diodes is installed where the system array is 200 Watts or more. We supply the bypass diodes free with the purchase of any 'Flush' wired solar panel.]
The Flush model is the preferred choice for deck mounting.
For general usage the Standard model will do the job ahead of the competitors.
