Devices and systems for ventilation of solar roofs
View Patent ↗This application relates to the ventilation of a solar roof. For example, a solar roof can include a solar roof tile and a spacer, batten or other ventilating components to space the solar roof tile from the roof deck, and provide ventilation to the solar roof tile, for reduced operating temperatures and improved efficiency in electricity generation.
1. A ventilation batten for a solar roof, comprising:
a body, comprising:
an upper surface configured to contact and support a downslope edge of a first roofing element; an upper spacer; and
a lower spacer;
a recess extending into a front surface of the body, the recess configured to receive and support an upslope edge of a second roofing element, such that the downslope edge of the first roofing element is spaced vertically apart from and horizontally overlaps with the upslope edge of the second roofing element;
wherein the upper spacer extends a first thickness measured between the upper surface and an upper portion of the recess;
wherein the lower spacer extends a second thickness from a lower portion of the recess to a bottom of the body, wherein the body comprises a single unitary construction; and
an opening extending through the body between the upper surface and the recess;
wherein the opening, the upper surface, and the recess are configured to provide ventilation through the opening between an external region above the first roofing element and the second roofing element, to an internal region below the first roofing element;
wherein at least one of the first roofing element and the second roofing element comprise a solar roof tile;
wherein the opening comprises a first opening, the ventilation batten further comprising a second opening extending through the lower spacer, the second opening comprising a third thickness; and
wherein the lower spacer further comprises a first foot and a second foot extending along a length of the body, wherein the first foot is horizontally adjacent to the second foot, and the second opening is formed between the first foot and the second foot.
2. The ventilation batten of claim 1 , wherein the body comprises a support member extending between and attaching the upper and lower spacers to each other, and forming the recess.
3. The ventilation batten of claim 2 , wherein the upper spacer comprises:
a first upper leg;
a first lower leg; and
a first middle leg extending between a portion of the first upper leg and a portion of the first lower leg, wherein the first opening extends through the first middle leg.
4. The ventilation batten of claim 3 , wherein the lower spacer comprises:
a second upper leg;
a second lower leg; and
a second middle leg extending between a portion of the second upper leg and a portion of the second lower leg, wherein the second opening extends through the second middle leg.
5. The ventilation batten of claim 4 , wherein the support member extends between an opposing end of each of the first lower leg and the second upper leg to form the recess.
6. The ventilation batten of claim 5 , wherein the batten comprises sheet metal.
7. The ventilation batten of claim 6 , wherein the batten comprises a single integral piece of material.
8. The ventilation batten of claim 2 , further comprising a clip extending from an upper portion of the upper spacer, the clip forming a groove configured to receive the downslope edge of the first roofing element, and secure the first roofing element to the spacer.
9. A solar roof, comprising the ventilation batten of claim 8 , further comprising the first roofing element and the second roofing element.
10. The solar roof of claim 9 , wherein the first roofing element comprises the solar roof tile, and the second roofing element comprises a roofing element different from the first roofing element.
