Collectors can be mounted on rooftops or anywhere near swimming pools that provide proper exposure, orientation, and tilt towards the sun. Both the orientation & tilt of the collector will affect the performance of your solar pool heating system.
Your contractor should consider them when evaluating your site's solar resource and sizing your system. Solar pool heater collectors must be geographically oriented to maximize the amount of daily and seasonal solar power they receive.
In general, the optimal orientation for solars collectors in the Northern Hemispheres is true south. However, a recent study has shown that, depending on your location and collector inclination, your collector can withstand up to 45º east or west of true south without significantly reducing its performance.
