If it doesnt say on the panel perhaps look for the make and model of the panel and look it up on the web?

Unable the panel is fixed and has no markings on it that are visible around the edges Cheers

Hi
Just measure the size and look on the web, ebay etc for the size of the ones they sell. Be close enough.

Yep, you could also look at the amps you get out of it when charging a low charge battery in full sun, for example I get a really steady 11 Amps out of 200 watt panels, pretty lousy as a measure as im sure there is a lot more that can affect it, but should give some idea

Perhaps look at the amps output when charging a battery that needs a fair chunk of charge (batteries near full charge take less amps) note that this can be affected by the battery and regulator so really a rough guess, but I get a steady 11 Amps out of my good quality 200 watt panels in good sunlight

As Jaahn said measure the panel, I'd also add to measure the cells and count how many there are. Get that info and post a pic of the panel and someone hear should be able to tell you what you have and it's output.

Or disconnect the leads from the panel at the regulator (as you said the panel was fixed and can't get to the back of it) and measure the short circuit current across them while the panel is in full sun. That will give you a rough enough idea.

Thinking outside the square.... Go see a mechanic, most on them have those inspection cameras on a flexible thin shaft. Perhaps it could slide under the panel and take a snapshot of the sticker on the back which should tell you what you want.

Smart phone can do that ? For pics ..
Just go by size ? 1580 x 808 x 35 mm is a 200 watt
100 watt is 1200x540x35(mm)

Yep I often look beyond the technology I have on hand. Looked at mine and it even has a timer function, so could set it up on a stiff wire, pass it under the panel & wait for the click. Or go 1 better & put it into video mode.
