(1) Contributes to increasing the total amount of generated renewable energy in Japan, by utilizing unused spaceon the roofs of existing detached houses (approximately 50 million units)(2) Offers 24/7 support for equipment repairs and upgrades for the entire period of residency to promote long-term
local production for local consumption of electricity(3) Strengthens preparedness for disasters causing power outages, with solar panels (energy creation) and storage
batteries (energy saving)◆Solar panel installation rate targets and challenges in installation
The Ministry of Land, Infrastructure, Transport and Tourism, the Ministry of Economy, Trade andIndustry, and the Ministry of the Environment are considering to set a target rate of 60% for theinstallation of solar power generation equipment in new detached houses by 2030, as part ofJapan’s aim to achieve a carbon neutral society by 2050. The Tokyo Metropolitan Government
aims to enact an ordinance in fiscal 2022, to require the installation of solar power generationequipment in newly built houses.
However, the current installation rate for newly built detached houses is estimated to be in therange of only 10% to 20%*³, and roughly 1%*⁴ for existing detached houses. Especially when
installing solar panels on existing detached houses, the burden of the initial cost, and problems
concerning earthquake resistance and the strength of the buildings have hindered the spread of
their installation. SUMIFU x ENEKARI aims to solve these issues, and to contribute to the spreadof residential solar power generation equipment, for which there is considerable room forexpansion.
