If that link works can somebody tell me if I am correct in deciphering the stats.... it is a 12V 200W panel

I find it frustrating that there is such a range of voltages in all the solar panels.
I thought most 12v panels should be around the 17 to 19V VOC and 24v around 34 to 38v VOC.
Watts is not so important unless you are mixing brands/types.
VOC of 22.6v is only OK for 12v but if using a 'good' MPPT regulator anything is possible.
Maybe post your intended purpose & what regulator you have in mind?

Thanks Bruce, The panel is on a market place site in Bundaberg for free and I was going to pick it up for my SIL who has a block up in the scrub and a couple of batteries I gave him to run a fridge and a couple of lights.

Grab it if it's free!! Plenty of cheap controllers will do the job.
Something like this.

That will handle up to 50V

Or this one if you want temp control as well.
You can get / make extension lead for the temp sensor for better control of charging .

I use 2 of them , one in the van and one for the ute's solar.

Turns out it wasn't free so I left him to it. Thanks for the help
