PVC Pipe and Pump Sizing Guide
We recommend that PVC pipe and the water flow rate for the solar pool heating system be sized according to the
pools water volume. The table below will help you choose the correct size PVC pipe for the
solar lines
running to and
from your roof.

When installing a solar pool heating system, it is imperative to check whether the
pump will provide the required water flow rate
at the pump height
of the
installation.
Panels installed above the roof structure with 50mm or greater underneath air gaps experience
much higher wind loadings and are now subject to the Australian wind loading standard
AS/NZD 1170.2.
It is the responsibility of the installer to consider wind loading factors, see “wind proofing”
section below.
If the installation site is within strong wind speed areas then the extra
stainless steel guide line must be installed across each row with the in-between panel
anchor points.
Do not assume supplied components are sufficient.
