How to successfully set up a solar panel black mat system

Now everyone has there own unique way of doing a solar setup but very few are effective or just do not function properly.

Below is a sketch of how we setup a solar mat system I hope this helps all in need of guidance.

So in a nut shell we have our In pipe which is going from the multiports return side, it then can be controlled on/off by means of a ball valve. From there it goes into the solar panels and up through the tiny little pipes and is then heated and passes out through the panels on the right hand side, down towards the return pipe back into the swimming pool.
