Pity.☹️
Before ripping all off for a rebuild, make sure about your angles.
Also have a look at Connect-it fittings. Maybe you can use them to alter your existing framework to suit.

Had a similar problem at my parents house

Front row was casting a shadow on the 2nd road, the solution was to lower the angle massively and slide the panels forward.
As you can see in the above, it over hangs the IBR roof slightly which isnt ideal, and at the lower angle, there is some lost efficiency, however, this is made up by the considerable increase in performance from not having shading on the rear 5 panels.

If you want/must go the higher frame route, I suggest measuring the needed lift now at the lower end of that row. (June solstice)

Can you give us some more info:
Does the carport have a flat roof, or is it slanted - if slanted, what is the approximate inclination?
What type of roofing do you have?
If strong enough, you could make some brackets from angle iron, or possibly even wood, to lift and angle your rear panels, and mount then on your roof / trusses. This would be easy if you have a flat roof, covered with IBR sheeting, on your carport. Also, if the carport abuts an external wall (e.g. your garage wall), you could mount some angle-iron "triangles" to mount the rear panels on...

If it's trees on your property an chain saw is the best solution but if it neighbours trees like by me were my 9 panel get from 16:00 in winter shading and neighbours don't care much for my problems as they don't have solar then really apart from moving the panels you really stuck .
I am off grid so 16 :00 shading makes the nights so much longer on batteries .

I’ve just fitted a 30 tube system to my HP geyser of 250L and today it got to one 70 degrees Celsius.
I must say the reduction in electric usage so far, with the Geyserwise in play, is awesome. Over 40 reduction in power consumption.

I have a 24V 2400/1200 inverter, as new, unused in the box for R2000.00
