Hi James,

Those panels look like they will work just fine. Since those are 185W panels, they will have a lower short circuit current than larger panels, so nothing to worry about.

Thanks Erik,

From my beginner research a typical 250W solar panel is usually approx. 38OCV and 8A. Watts are Watts but does the Solar Tracker do something special with a high OCV panel that would make it more efficient etc? So would using an 185W panel with 45V OCV 5.5A be more efficient than a 250W, 38V OCV 8A panel when used with a Solar Tracker?

It's just that John mentions using a high OCV panel.

Possible a stupid question but for all intents and purposes I am stupid when it comes to this But I'm learning.
