Solar panel cover down

Here it is with the cover down. Now some of you may not be used to seeing the panel on the wall - but in the morning the panel is almost 90 deg to the sun & it's cold - so I expect to get max power when the sun comes up & again when it goes down.

During the day , the hotter the panel is - over 25 deg C or about 70 deg F the less power it will produce. At 85 deg and full sun - your panel will easily be over 110 deg F , I would guess you may only get 50-60% solar if that much.
