Solar heater location and pump question

I am planning on installing a solar heater at the rear of my pool. This run is about 60' away from my pump so my pump would have to move water and extra 120' (plus the solar heater). All equipment and pool is on level ground.

Do I need to be concerned about the HP of my pump?

Should I be concerned about straining my pump?

Should I run 3" pipe to the solar panel or is 2" ok? The fittings on the solar panel are 2".

The reason for locating the solar heater at the rear is sunlight. I get full sunlight there.

I also hope to find black PVC to run to the heater because it can help heat the water.

If you can get 3" for not much more than 2" pipe then do it as it will have almost no pressure drop. As for black PVC I don't think I have seen that, but why not just use white pipe and paint it black yourself.

Yes I had thought of painting as well.

My main concern is the pump. Will I be putting a strain on it or should I purchase a bigger one. (more HP)

"Strain" is not really an issue with a pump. As long as it has enough head to initial get water flowing through the panels you really should not have a problem. I would not pre-buy a bigger pump. Try the one you have and you can always upgrade it if need be. To install a bigger pump if not needed will just cost you money for a pump and higher electric bills.

Thank you. I appreciate the quick response.
