Newbe question, parallel panels

Is it ok to parallel panels of different wattage, but the same voltage?

You should be wary of the big one cooking the small one with back current given that they won't be identical, so I put reverse blocking diodes in when I do that (I have 2.5W and 100W in parallel with a bunch in between too).
