When will solar panels become mandatory in Tokyo?

An employee at a homebuilding company discusses solar panels with customers in Koganei, Tokyo, on March 23. New homes and residential buildings in Tokyo must come equipped with solar panels as of April 1, when a revised ordinance from the metropolitan government takes effect.

Do new homes in Tokyo need solar panels?

New homes and residential buildings in Tokyo must come equipped with solar panels as of April 1, when a revised ordinance from the metropolitan government takes effect. The original ordinance was the first of its kind in Japan, and after it was enacted, other cities and municipalities began requiring solar panels be installed.

Will Tokyo subsidize solar panels?

In March last year, the Tokyo Metropolitan Government established a 150 billion yen fund to subsidize the installation of solar power generation equipment for Tokyo residents. Subsidies will be provided if solar panels are installed during the construction of new eco-friendly houses or while retrofitting existing houses with insulation.

Why did Tokyo adopt a solar power ordinance?

"The ordinance was an opportunity for people to get a better understanding of solar power generation," said the manager of the company's Koganei branch. Although solar power provides clean, carbon-free energy, Tokyo has few open spaces large enough to build a major solar power plant.
