As electric vehicles (EVs) become more widespread, we explain EV charging facilities in rental housing and how solar panel-equipped properties work. This guide covers types of EV chargers, electricity cost responsibility, negotiation strategies for retrofitting, and the pros and cons of solar power generation.
As environmental awareness rises and energy costs increase, rental properties equipped with solar power generation panels and EV (electric vehicle) charging facilities are becoming more common. The government's "2050 Carbon Neutral" target and the "Residential Energy Efficiency 2030 Plan" are driving momentum, with major developers and property management companies leading the acceleration of eco-conscious housing adoption.
This article explains the reality of solar panel and EV charger-equipped rental properties, their benefits and drawbacks, and key points for choosing properties with these amenities in the future.
There are primarily two patterns for installing solar panels in rental apartment buildings.
①Rooftop Installation (Shared Facility)
Panels are installed on the building's roof or rooftop, and the generated power is used for common areas (hallways, elevators, entrance lighting, etc.). Tenants benefit indirectly through reduced maintenance fees.
②Individual Unit Supply Type
Some new and renovated properties feature "solar-sharing apartments" where excess solar power is allocated to individual units. In these cases, daytime electricity costs can drop significantly.
The Japanese government has set a target of making 50-70% of new car sales EV and PHEV by 2030, making the development of charging infrastructure urgent. In response, subsidy systems for EV charger installation in rental apartment buildings have been established (such as the Ministry of Economy, Trade and Industry's CEV subsidy).
①Standard Charger (200V, 3kW–6kW)
The most common installation type. Overnight charging provides approximately 100–300 km of driving range.
②Fast Charger (CHAdeMO and CCS Compatible)
Common at commercial facilities, but still rare in rental apartment buildings due to high installation costs.
③Smart EV Charging System
Combined with solar power generation, some properties now feature "V2H (Vehicle to Home)" systems that charge EVs with daytime-generated power.
Beyond solar and EV charging, more properties are featuring other eco-conscious amenities:
| Equipment | Overview | Tenant Benefits |
|---|---|---|
| High Insulation and Airtightness | Upgraded insulation materials and window glass | Reduced utility costs, stable room temperature |
| LED Lighting and Motion Sensors | LED in all rooms + sensor lighting in common areas | Reduced electricity costs |
| Water-Saving Faucets and Showerheads | Equipment that reduces water consumption | Reduced water bills |
| HEMS (Home Energy Management System) | Visible energy consumption tracking | Reduced waste |
| Delivery Boxes (CO2 Reduction) | Eliminates redeliveries, reducing logistics CO2 | Improved convenience (no need to be home) |
You can efficiently find properties with these amenities by filtering rental search sites using keywords such as "solar-equipped," "ZEH (Net Zero Energy House)," "energy-efficient property," and "EV charging available."
Buildings certified by the Ministry of Land, Infrastructure, Transport and Tourism as "Long-Life Quality Housing," "Low-Carbon Housing," or meeting "ZEH Standards" tend to have higher equipment standards. Even in the rental market, properties with these certifications are gradually increasing.
While solar panel and EV charger-equipped rental properties tend to have slightly higher initial costs (rent), long-term residents can expect savings on utility and charging costs.
Why not add "environmental performance" as a new factor in your next rental property search?
