This maximizes the energy production over the course of the year, through both summer and winter. Sometimes, however, the homeowner will want to add modules on the north-facing roof. This may be for aesthetic purposes, or sometimes because the south-facing rooftop isn't fit for solar. The most common rule-of-thumb is that you simply can't do that.
It's considered common knowledge that you want to point your solar modules south, toward the equator (assuming you are in the northern hemisphere). This maximizes the energy production over the course of the year, through both summer and winter. Sometimes, however, the homeowner will want to add modules on the north-facing roof.
As can be seen in the chart below, for our original reference project in Charlotte, the north-facing array is nearly identical to the south-facing array in the summer months, when production is greatest. While the differences are much larger in the winter months (over 20%), the energy yield during those times is much smaller.
The north-facing section of 1/12 roofs are likely to be extremely profitable, while 2/12 rooftops (and select 4/12 rooftops if they are not perfectly facing south) would be worth consideration for the system design. Here are a few examples for Charlotte, Miami and Minneapolis:
