Question 1

How many watts output are you guys getting with this Renogy 50 watt flexible solar panel?

Accepted Answer

In good conditions You may get 2 1/2 amps

Question 2

I have to run this 12' to get to my battery on a kayak.  Can the cables be changed out or spliced into to make the run /should I increase wire size

Accepted Answer

You can get snap-together cables from the Home Depot website, or the Renogy company directly- a variety of lengths are available. It's always better to go with a decent size wire gauge, but if a nominal size is the only one available, it'll still work since you're not running a high amp load anyway.

Question 3

To connect these solar panels in parallel will i need y connector or t connectors? Also to connect panel to panel will i need some kind of extension?

Accepted Answer

For parallel, you are in general just looking at using y connectors. There are 2:1, 3:1, etc. available. With parallel, just keep an eye on amps since that will go up with each additional panel connected. to connect panel to panel (I'm taking that to mean a serial connection), you don't need anything since you would just connect the positive of one panel to the negative of the other and when you are done connecting you panels you have one positive and one negative free and those are what you connect to the controller. With this serial arrangement you just need to keep an eye on voltage relative to your controller.

Question 4

Solar panel is showing voltage but zero amps on the controller.  battery now depleted.  is this panel bad?

Accepted Answer

According to the manufacture (Renogy) it should put out a maximum of 18.5 Volts at output operation current of 2.71 amps.  Your battery may be bad.  I would replaced the battery first and remember to connect the battery first before connecting the solar panel.  If you still don't show any current then you could have a bad charger controller.   The solar panel can be check by placing an amp meter in series with a load.  Amps = the Voltage divide by the Resistance.  According to the manufacture the maximum short circuit is about 2.92 Amps.  Note this is in Bright Sun Light.
