Hi,
You will need to make some "spot" measurements with a multimeter (volts range). The + and - inputs on each Op-Amp should always be at exactly the same voltage (probably around 100 mV with fairly bright sun) and the output about 7 times larger, say 700 mV, relative to ground.
What Op-Amp are you using? I don't recognise the particular pin connections shown.
Cheers, Alan.
