3.5 Setting the Solar Arr ay Tilt Angle
Some solar array racks are adjustable to a desired angle, to accommodate both the location and the
season. We offer these choices for seasonal management.
1. YEAR-ROUND COMPROMISE (no seasonal adjustment) Set the angle equal to the latitude of
the location and “forget it”. This is good if the pool is to be used year-round.
2. SEASONALLY ADJUSTED This is good if you want to maximize performance for both the winter
and the summer-half of the year. It is sufficient to perform the adjustment only twice per year, at
the spring and autumn equinoxes, to the angles indicated below. For central USA, daily water
production will be increased by about 8% in summer, 5% in winter compared to option 1. There is
less advantage in a cloudier climate. If adjustment is difficult or is likely to be forgotten, this is not
a good option.
3. SUMMER USE For use only during summer half of the year, set the array to the seasonal
angle shown below, and “forget it”. The pump will function in the winter, but at a substantially
reduced pumping rate.
Ideal angles (from horizontal) are: Summer optimum = latitude -15° Winter optimum = la 15°
