remind me of how many m2 of panel you are putting in? You only need .25-.6L/m2/minute so if you have 10 x 2m2 panels x .6L= 12L/m or 3.2gpm-MAX. Try the T-D pump with a 30w panel.
The other issue is max temp on the panels. Most PEX systems won't last very long unless you are keeping it really low temp (less than 180F) and I don't know the specs for the panels. If you are going to bury it you want to be sure.
