Integrated composition shingle PV system
View Patent ↗An integrated composition shingle PV system is interengageable with composition shingles, the composition shingles being arranged in overlapping rows on an inclined support surface. The system comprises a carrier mountable on the support surface. The carrier has flashing along its peripheral edge. The rear flashing is positionable under a first row of overlapping rows of composition shingles. The left side and right side flashing are interengageable with second and third rows of overlapping rows of composition shingles. The front flashing is positionable on top of another row of overlapping rows of composite shingles. A PV laminate is secured to and supported by the carrier.
