Are solar panels required in Tokyo?
All new detached houses in Tokyo after April 2025 are required to have solar panels installed. However, if you are purchasing a property in a different part of Japan, it's possible that solar panels may not be mandated in the region.
How is Tokyo promoting solar power generation?
The Tokyo Metropolitan Government is actively promoting the adoption of solar power generation through various incentives to support residents and builders in transitioning to a decarbonized society. These incentives are designed to reduce greenhouse gas emissions and increase energy efficiency across the city.
Will Tokyo require solar panels on new detached houses?
This will make Tokyo the first place in Japan to require solar panels on new detached houses. The ordinance will come into force in April 2025. “We have gone ahead with requiring businesses (to install solar panels),” Tokyo Governor Yuriko Koike said at a news conference held after the ordinance was approved.
How much do solar panels cost in Tokyo?
But some have raised concerns about the costs of installing and managing solar panels, which are estimated to be around 1 million yen ($7,280) per house. Many houses in Tokyo have roofs that face north so that they do not block the sun from shining on neighboring houses.
How many buildings in Tokyo need solar panels?
According to the Tokyo metropolitan government, around 50,000 buildings and houses are built in Tokyo each year, and around 20,800 of these will need to have solar panels under the new rules. Around 20,000 of those qualify as other smaller structures in the second category.
How many kilowatts is a mega solar system in Tokyo?
Mega solar installations boasting gigantic panels with a capacity of 1,000 kilowatts or more are also rare in Tokyo, where there are not many open spaces. The metropolitan government estimates the new solar regulations will lead to an additional 40,000 kW of power generated per year.
