1.85 THP VS pump @ at 2000 rpm, 8 panels (12’ up on roof), new VRV. When solar is on, there are constant “champagne” bubbles from returns in pool. Spring check valves on 2” lines to/from panels. No suction side air leaks, but I can’t get the bubbles to stop. If I increase the pump speed the bubble intensity increases also...

Welcome to the forum!
Do you happen to have a SaltWater Chlorine Generator?
Please fill out your signature when you can.
I suggest you read ABC's of Pool Water Chemistry.

Great.
Bubbles come from the suction side. So check your pump basket lid gasket, clean, use pool lubricant, and reseal. Check pump drain plug seals, any valves on suction side, etc.

Just had all that done and it resolved 2 suction side leaks, but no help with the bubbles...

Air comes from the suction side. It cannot enter the pressure side.
When your solar is called for, does the pump ramp up to a higher rpm to clean the system of air and then ramp down to operating rpm?

not automatic, I have ramped it up manually, but all that does is increase the bubbles.

You have more suction head when the solar is running. Most likely source is the pump basket lid. Has it been lubricated with proper pool lubricant? Silicone base, non PTFE.
O-ring and pump basket lid are fine. Something odd started showing up...pump basket randomly losing “prime”. Pump running fine and suddenly the water level in basket drops, turn off pump, re-prime basket and it’s fine for a while. Then randomly it wil drop again...

Motor RPM = 3450
Curve A = 64 GPM
Curve B = 38 GPM
Curve C = 85 GPM

If you’ve changed nothing then I guarantee there is a bad o ring, bad cover fitting or spider crack somewhere.
Also check the weir to be sure it’s free floating and not stuck in closed position.

Have you tried running the hose over everything while it is running to see if the bubbles go away? It must be a leak but could be where the plumbing fittings meet. I had a leak once where a slip fitting was leaking. It also provided tons of bubbles. I slathered PVC cement all over all the suction side fittings I could find and the leak went away.
They were out this morning and lubed/replaced all o-rings..everywhere. Found a return in spa that was actually drawing water back into the return! Actually found 2 of them filled with “debris”...
