I checked output again at 7pm and it was making 45 watts or so

. Array angle isn't the problem. Went out and felt the panels, they were fairly cool now, the inverter felt the same as earlier. Got under the array and checked the array voltage, I think it was around 38 volts

. Now that made me go back and check the input parameters to my inverter. It looks like the info I printed off gives the minimum DC input voltage as 44 volts. So what the heck is going on? I might be having some kind of inverter issue. It should have been producing earlier when it was in the 46 volt range, especially if it was working below 40 volts just a while ago. I'll have to do some connection checking.
