Collectors in the same line must be connected so that the heat transfer fluid flows through them in series.

Lines of solar collectors can be connected either in series (provided each line contains no more than 6 collectors) or in parallel. The 

complete circuit must always be hydraulically balanced. See the following sample layouts.
