Solar Collector Orientation
Operating your Free Hot Water solar water heater for optimal efficiency is based on the correct orientation, pitch,
and location of the solar collectors. In North America, collectors should be oriented due south, however may be
oriented up to 45 degrees east or west of due south with minimal losses in solar gain. Optimal pitch is +/– 10° from
the latitude of the installation site.
Free Hot Water solar collectors must be installed at a minimum pitch of 15 degrees from horizontal, and for optimal
performance, the recommended pitch is between 15–60 degrees. The collector should be mounted as close to the
storage tank as possible to minimize heat loss in the piping runs. The solar collector must be located in an area of
the roof that will be un-shaded for the majority of the day (from 9:00–3:00) all year round. Adjacent buildings and
trees should be checked for possible winter shading.
The following diagram below is an example of how the collectors can be connected to one another. However, the
actual connection may be different depending on structural conditions. A maximum of 6 collectors may be
connected in a series! If a collector panel is made up of more than 6 collectors, the panel must be connected several
times in parallel
