Capital of Japan Requires Homebuilders to Install Solar Panels on All New Homes Beginning in 2025

Tokyo To Require New Home Builders To Install Solar Panels Starting in 2025

Tokyo, the capital of Japan, with a population of 13.96 million residents, has just passed a new regulation that requires large-scale builders of new homes to install solar panels on every new home built beginning in April of 2025.

Tokyo Governor Yuriko Koike noted that currently only about 4% of homes within the city that could have a solar panel system actually do. The governor aims to halve the annual greenhoure gas emissions by the year 2030, as compared to the year 2000 emissions.

The new regulation does not require that a solar energy battery bank – typically lithium ion batteries – be installed along with the solar panel system.

CNN Business reports:

“Large-scale homebuilders after April 2025 must install solar power panels to cut household carbon emissions, according to a new regulation passed by the Japanese capital’s local assembly Thursday.

The mandate, the first of its kind for a Japanese municipality, requires about 50 major builders to equip homes of up to 2,000 square meters (21,500 square feet) with renewable energy power sources, mainly solar panels.

Tokyo Governor Yuriko Koike noted last week that just 4% of buildings where solar panels could be installed in the city have them now. The Tokyo Metropolitan Government aims to halve greenhouse gas emissions by 2030 compared with 2000 levels.”
