THE OBJECTIVE OF THE PROJECT IS TO IMPROVE THE BANKABILITY OF ROOF-INTEGRATED SOLAR PHOTOVOLTAIC (PV) SHINGLE SYSTEMS BY REDUCING THE MARGINS OF UNCERTAINTY OF EXISTING THERMAL AND ENERGY PRODUCTION MODELS. ROOF-INTEGRATED PHOTOVOLTAIC (PV) SHINGLES, ALSO REFERRED TO AS “SOLAR ROOFS”—WHERE THE PV MODULE IS AN INTEGRAL PART OF THE WEATHERPROOFING ENVELOPE OF THE BUILDING—BRIDGE THE GAP BETWEEN PHOTOVOLTAIC GENERATION TECHNOLOGY AND TRADITIONAL ROOFING METHODS AND MATERIALS.
