Without the model number and specs of your panel, it's hard to give a detailed answer. If this is a new setup, possibly this is normal operation. It is near sunset, after all, and the sun is coming in at a low angle. As an example, it's 8 am where I live right now, maybe half an hour after sunrise, and I just read 96 watts coming from our array. At this time of year, we see about 2100 watts at noon. So look for indications that what you see is not normal. If there is more than one panel in the system, compare your suspect panel with another, for short circuit current, and open circuit voltage. If the system was working at a certain performance level, and suddenly failed, that's also a sign that something went wrong.
