An ＇＇exchangeable photovoltaic (PV) shingle＇＇ which is a new type of PV module integrated with a shingle tile has been developed. The new PV shingle tile offers many attractive features, such as a lower total cost, simple construction and maintenance, good design, and fire resistance, compared with previous PV modules. The PV shingles were trial tested and evaluated as PV modules and roofing materials, and no problems appeared. This year, the PV shingles were installed on a model house roof to conduct demonstration tests related to various performance levels for a solar cell system and roofing materials.
