The
Japanese government decided to introduce photovoltaic generation to elementary and junior high schools and use them as the base to supply
electricity to the surrounding area. The Ministry of Land, Infrastructure,Transport and Tourism and the Ministry of Education, Culture, Sports, Scienceand Technology will construct facilities for photovoltaic generation in
selected schools in the disaster-stricken areas and expand the plan throughout
the country. In parallel with the introduction, the schools will be renovated
to be energy-saving and quakeproof utilizable as the evacuation area in a time
of disaster. In the March 11 disaster in 2011, more than 6,000 schools were
affected, of which about 200 schools reportedly need renovation.
Solar
panels will be installed on the rooftop of buildings and gymnasiums of selected
schools. The renovation cost is estimated at 100 million yen per school. Unlike
a standard household, a school consumes electricity mostly for lighting. In
addition, it can store electricity on Saturdays, Sundays, and vacations in
summer and winter. It is estimated that a school can satisfy the power demand
of about 30 households. Several schools have installed solar panels on an
experimental basis, but no schools have ever tried to provide the integrated
service that includes power storage and supply besides power generation. The
two ministries hope that their plan will support the technological innovation
of private companies. A school is not allowed to supply power to outside
premises at present, but the two ministries are discussing deregulating the
existing rule as a special case.
