Project summary
MSK corporation is the largest PV module manufacturer. The Nagano factory is the world’s largest PV module manufacturing plant with a production capacity of 100MW. PV system was installed on the roof and as a façade of the building, as a demonstration project of PV system, and the capacity is 62kW in total; 58kW – on the roof & 4kW – as façade. The PV system was installed as “Field Test Project on Photovoltaic Power Generation Systems for Industrial and Other Applications”, which is one of the demonstration project schemes. In this scheme, half of the cost is subsidized by NEDO and various kinds of operational data are monitored.

Special PV project info
PV architecture and building integrationPV modules on the roof were fixed in a low tilt angle to restrain a wind loading. Then, to reduce array interval could help to make effective use of the roof area, and to simplify the array structures could contribute to reduce the cost. Although temperature of PV modules might buildup caused by low tilt angle installation, by temperature characteristics of amorphous Si PV modules the efficiency could be better. As a façade of the building, transparent PV façades were applied instead of regular glasses. The PV façade is creating attractive design of the building and having the PR affect. By using three kinds of penetration efficiency of transparent PV façade, optical transmission into the building is adjusted.
