Maximizing Solar Production

An important part of the roof plan is the photovoltaic panels. While there are no structural concerns for adding a PV array to this roof system, Maines took several steps to optimize the roof for an array. With a two-story eave on one side and a one-story eave on the other, the house is essentially a saltbox. Orienting the two-story facade with the unbroken roof plane to the rear for southern exposure was important to accommodate the 12kw array needed for net zero. Consolidating all of the plumbing into a single vent stack maximized the usable area. While a steep roof was desirable for aesthetic reasons, the 10-in-12 roof pitch — between the ideals for summer and winter — was chosen to maximize production over the course of the year.
