Roofing underlayment for solar shingles

A roofing underlayment for solar shingles comprising:

• a water-impervious membrane adapted to be attached to a roof by adhesive;
• a mechanical attachment member running substantially the length of the membrane and have multiple alternating embedded portions within the membrane and extending portions extending above the membrane, wherein the extending portions each are configured for mechanically attaching solar shingles to the roof;
• an electrical conductor running substantially the length of the membrane and having at least a first embedded portion embedded within the membrane, having multiple connecting portions extending above the membrane configured to electrically connect to solar shingles, and having a third portion configured to plug in and electrically connect to an electrical circuit;
• wherein the connection portions and the electrical extending portions are positioned and configured so that solar shingles are mechanically attached and electrically connected simultaneously and without creating holes through the membrane;
• and
• an air gap area that allows for air flow below solar shingles;
• and
• wherein the air gap area comprises an area between a bottom surface of solar shingles and a top surface of the membrane.
