integrating solar pool heater into pool with in floor cleaners

My dad wants to add solar pool heating systems for our pool, which has an in floor cleaner.

I know this can be a tricky wicket with those high pressure cleaners.

those existing pumps often run out of steam trying to push enough water for good solar heating, especially with the extra back pressure from the panels.

Short of biting the bullet and getting a booster pump, the obvious move is to kill two birds with one stone and return the solar heated water through other pool returns. We can even set that up with automation when the solar's doing its thing.

What do you think guys, is this a good idea? Do you guys have any other ideas?
 
From what I get, in-floor heating systems with an in-floor cleaning system usualy need about 60 GPM per zone, or need a lot of pressure which is pretty much what solar setups require. Using separate returns for the solar-heated water is a smart move. It eases the pressuer on the in-floor system and can be set up easily. A variable speed pump can help manage the flow for both systems, and if that's not quite enough, adding a little booster pump for the solar loop would do the trick nicely

By balancing both loops with a variable speed and adding a booster when necessary, performance can be maintained without putting too much strain on either system. I'm pretty sure it's clever utilizing separate returns.
