Tokyo''s new solar panel mandate: ''Can Japan
This article covers considerations on Tokyo''s new solar panel installation mandate, current energy generation challenges and examples
There has been a great response to the Tokyo Metropolitan Government's announcement in 2022 of “ the mandatory installation of photovoltaic power generation for new buildings ” and the term “the mandatory installation” seems to have made a particularly strong impression.
The Tokyo Metropolitan Government's Bureau of Environment's solar power portal site provides detailed explanations of not only the “subject of the mandatory installation,” but also the implementation date of the program (April 2025), “benefits of installing PV system,” “actual costs,” and other details.
Nearly all houses in Tokyo will have to install solar panels after April 2025. The regulation - passed by the Japanese capital's local assembly on Thursday - requires 50 major construction firms to equip homes of up to 2,000 square metres with renewable energy power sources.
But Tokyo lags in its uptake of renewable energy. Just four per cent of buildings with the capacity for solar panels currently have them. The new rule will help change this. Overall, the measure will save residents money, the metropolitan government says.
