Nissan LEAF in Japan: Free Solar Arrays for Electric Vehicle Owners
Combining zero-emission driving with solar-powered households, Nissan and Ecosystem Japan offer a unique incentive for eco-conscious Japanese buyers.

Nissan LEAF in Japan: Pioneering Electric Vehicles and Solar Power Integration
The electric vehicle (EV) revolution has long promised not only cleaner air, but also a complete rethink of how we generate and use energy. In an ambitious move that brings these ideas together, Nissan Motor Company has launched a joint campaign in Japan offering free solar array installations for buyers of its new Nissan LEAF, in collaboration with Ecosystem Japan. This innovative program aims to foster a new era where driving an EV is more sustainable than ever, by allowing owners to charge their cars with electricity generated right from their rooftops.
Background: The Nissan LEAF and Japan’s EV Landscape
Since its first release, the Nissan LEAF has been a global pioneer among mass-market electric vehicles. The all-new model, launched in September 2017, introduced enhanced capabilities, better range, and smarter tech, reaffirming Nissan’s commitment to sustainable mobility. Japan, a leader in both technology and environmental policy, provides an ideal stage for promoting the synergy of renewable energy and electric transportation.
The Joint Campaign: How It Works
The partnership between Nissan and Ecosystem Japan targets new LEAF buyers, offering them more than just the vehicle. Here’s how the program unfolds:
- Eligibility: Owners of the newly released Nissan LEAF in select regions of Japan, particularly the Kanto area, are eligible for a free home solar panel installation.
- Power Plan Requirement: To qualify, buyers must sign up for Ecosystem Japan’s “Jibun Denryoku” (Personal Electricity) plan, a retail program designed for forward-thinking households committed to clean power.
- Discounted Daytime Assist Plan: Participants can further benefit from discounts on the “Daytime Assist Plan,” which encourages EV charging during daylight hours using solar energy or at night when grid demand is lower.
Key Offer Details

---|---|
Free Solar Array | Qualifying new Nissan LEAF buyers receive a solar panel system installed on their home, paid for and maintained by Ecosystem Japan during the contract. |
Personal Electricity Plan | “Jibun Denryoku” plan locks customers in for 20 years, facilitating clean energy use and offering buy-back rates for surplus energy produced. |
Daytime Assist Plan Discount | Discounted electricity for daytime charging, incentivizing maximum solar utilization and reducing strain on conventional grid supply. |
Transfer of Ownership | After the 20-year plan concludes, the solar installation becomes the homeowner’s property at no extra cost. |
Coverage Area and Deadline | Initially available to customers in the Kanto region; promotion runs until March 31, 2018. |
Motivation and Vision Behind the Initiative
This campaign is much more than a simple sales incentive. Nissan and Ecosystem Japan aim to:
- Accelerate EV adoption by reducing the barriers to sustainable driving.
- Promote renewable energy use in homes, linking clean power generation directly to emission-free car travel.
- Reduce Japan’s reliance on fossil fuels, both for transportation and household energy needs.
- Encourage smart charging: Owners are incentivized to charge their EVs during off-peak hours or when solar electricity is available, balancing grid load and maximizing green energy use.
A Model Inspired by Industry Leaders
Nissan’s approach parallels strategies seen in the industry, most notably by Tesla, which has already bundled solar panels and electric vehicle sales in its U.S. showrooms. The initiatives reflect a broader trend: integrating home solar generation with electrical mobility, enabling consumers to take greater control over their carbon footprint.
How Does the Free Solar Plan Work?
Let’s break down the experience for a new Nissan LEAF buyer who signs up for this offer:
- Purchase a new Nissan LEAF in Japan’s Kanto region during the campaign period.
- Enroll in Ecosystem Japan’s Jibun Denryoku electricity plan, agreeing to use their electricity services for 20 years.
- Receive a solar panel system installed at no initial cost; the array is maintained by Ecosystem Japan.
- Benefit from reduced daytime electricity rates and the opportunity to charge the LEAF using solar power.
- At the end of 20 years, full ownership of the solar system is transferred to the homeowner — free and clear.
Throughout the contract, both installation and maintenance costs are covered, eliminating upfront expenses and worries about ongoing servicing.
Benefits for Homeowners and the Environment
- Zero Initial Cost: Solar system installation is fully subsidized for as long as the participant remains on the plan.
- Lower Electricity Bills: Homeowners use self-generated power during the day, often reducing dependency on grid electricity and associated costs.
- Reduced Carbon Footprint: A completely emission-free driving and household power experience when EV charging and domestic needs are met by solar energy.
- Energy Independence: Over time, solar systems can reduce vulnerability to energy price spikes and supply disruptions.
- Long-Term Asset: After the 20-year contract, the solar system becomes a valuable home asset.
Potential Limitations and Considerations
- Long Commitment: The requirement to remain on the electricity plan for two decades may not suit everyone.
- Regional Restrictions: The campaign is limited to specific regions (not nationwide) and runs for a set period.
- Home Suitability: Not all homes may be suitable for solar installations (e.g., due to roof orientation, shading, or building structure).
- Ownership Transfer: Ownership of the solar system is only granted after the full contract period.
Context: Solar and EV Trends in Japan and Beyond
Japan is a global leader in both solar adoption and electric vehicle infrastructure, but the majority of the country’s electricity still comes from a mix of sources, including natural gas and coal. Integrating rooftop solar with electric vehicles addresses both household energy use and transportation emissions, closing the sustainability loop.
Worldwide, the model echoes similar experiments in Europe, the U.S., and Australia. As policies and consumer awareness grow, more automakers and energy providers may bundle solar arrays with EV sales, fostering rapid, parallel growth in both sectors.
How Nissan’s Solar Campaign Stands Out
- Market-First Bundling: Nissan’s campaign is among the first to offer a fully bundled EV-and-solar package for regular consumers in Japan.
- Focus on Sustainable Living: By targeting both transportation and residential energy use, the offer prompts lifestyle changes with immediate, tangible benefits.
- Corporate Collaboration: The partnership with Ecosystem Japan leverages expertise from both automotive and energy fields.
Consumer Journey Example: From Showroom to Solar Power
Consider a typical buyer’s experience:
- Kazuki, living in suburban Tokyo, purchases a new Nissan LEAF in early 2018.
- He signs up for the Jibun Denryoku plan with Ecosystem Japan, committing to their energy service for 20 years.
- Within months, solar panels are installed on his rooftop with no upfront cost.
- Kazuki charges his LEAF during sunny days using home-generated electricity, slashing both car “fuel” and household energy bills.
- Two decades later, he becomes the sole owner of the solar system — a key asset for his family’s future.
