Dilligaf,
you bought a Sharp (?) watt panel, then a Suntech 80 watt panel, ???
*you don't have protective polly film over the alloy frame of your Sharp panel ?
*the Sharp alloy frame is not double thickness for the full length ?
*all the attaching screws are not countersunk into the frame ?
None of the above apply to the Suntech panel - do they !!
You will be able to look at the two panels you have, to see the distinct differences mentioned in the construction and appearance of the two panels, your so lucky... L0L
Getting down to technical differences will take some testing...
(1) Put both panels on their back in the sun, side by side
(2) Attach the cable from both panels to the solar regulator
(3) Attach the cable from the regulator to a 'low' battery
(4) Read the Amps going into the battery from the two panels
(5) Cover one solar panel with a towel or similar object
(6) Read the Amps now going into the battery
(7) Remove towel and place on the other panel
(8) Read the Amps now going into the battery
(9) leave both panels in the direct sun for a few hours, repeat the
test again and you will see the difference in the Amps, between the two panels, going into the battery when the surface of the solar panel gets hot, as does in real life when camping, that is why some panels do work far better than others in the heat.
