pump size for solar bear panels

I just received (2) 4x 20 solar bear panels and intend on installing them on a roof surface 8ft above and 12 ft away from my pump and filter. I have a Hayward 1/2 hp pump right now. Will this pump push the water through both panels at a decent rate?

Typically with solar, if the pump can fill the panels on start up, it will work. After the panels are full, the suction created by the water going down after the panels pretty well compensates for the work needed to lift it. Overall, there's very little extra load.
