What's wrong with your meter, totaly dead, not working on just amps, ran over by a truck?
I probably can't help with the solar amps problems. I would measure a 15watt HF panel today for you but I am in woods, can't set one up and just leave it all day 9-5 as it will be in the shade allot, early in morning and after about 3pm unless I move it around. I have mine set to catch the best sun, about 11-3 when sun is nearly straight up, other times they get partly shaded and that messes up your readings, so would moving it.
Looks like it might be a decent day today, so I'll try to find a spot to test 1 panel better. So check back tonight, maybe I can post you some readings? I go set one up now.
Here's a couple ideas to check out your meter, maybe you can fix it quick. Stuff that goes wrong with mine.
If your meter is like mine, a cheapo, I buy allot of those to keep laying around in vehicles and such, maybe this will help fix the meter.
If your meter is not working at all check the batteries, most are a 9V square type, make sure it's not dead of course and snaped on tight. If the 2-3 AA batteries make sure they are all ok and making good connection.
What ever type batteries, check on the circuit board at the power input pins and see if your getting the voltage you should. If you can't check voltage cause this is your only meter, just find some low volt item like a tiny DC motor or small bulb and touch the leads to the pins, it should run or if a low volt bulb light up. I have found a broke wire in the 9 volt connecter before and a bad wire or connetor in the AA types also, so with good batteries the meter still did not have power.
If the meter is working, turning on, but not reading anything, check your test leads of course. With some of the cheapies I have had a broke wire, or even the test end just falls off. Set to continuty test and touch leads together, if nothing then unplug one wire and poke around in that hole with the other lead still plugged in, you should get a conection. If the meter shows the conection then do the other lead.
If the meter was out in the rain or dropped in a bucket of water, it won't work while wet. Take back off and sit in warm sunny spot to dry, it should be fine later, mine normally are once all the water is out and it dries. Sometimes I forget and leave one laying in the back of a P/U truck so I KNOW that one well 
If the circuit board has cruddy looking stuff anywhere brush it well with a dry toothebrush. If needed use rubbing alcohol or preferably Denataured if you have some.
If lCD diplay was knocked loose, put it back in place, it should work. It's just a press fit with a little white/grey rubber looking strip between it and the crcuit board. If LCD is showing goofey looks not readings, take meter apart and wipe LCD clean with soft dry rag and put it back in, also wipe the rubber strip gently one contact ends, it may work perfect again, mine do.
The twist dail on front of meter has 1 or 2 steel balls that pop into holes as you turn it, the click feel that holds it on a setting. It also has a small copper strip that contacts the circuit board to chose the settings. Don't loose the balls or strips, take out the circuit board and clean the contacts, clean the copper strips, make sure balls are still in there and put back together, that fixes some things. If the meter is working but not reading on 1 or 2 settings that could be it.
If a better meter you may have a fuse for the amps setting as mentioned by others. If the same type cheapy I use allot there is no amps fuse. I think there is a fuse inside but it's not for amps, at least when I run 115 amps though my meters it never blows! I just smoke the leads abit insead of blowing the fuse. Ya, sometimes I forget to check the meter leads and I was using it to test amps on something, then I set it to DC Volts and check a 115amp battery to see it's voltage, hot wire!!!
It normally takes a few times doing that before I burn out a lead, I remove it real fast when I make that mistake! If you have done something like that check the leads good, mine normally burn out the NEG lead on the meter side, looks fine but a broke wire inside right at the plug.
I rarely have a meter not working that's not one of the above, but they do screw up or just die at times, something above normally fixes the average problems though.
