Off-Grid Living in a Compact Abode, Powered by Solar Energy for My Nissan Electric Vehicle
More and more people are embracing the off-grid lifestyle, drawn by the desire for freedom, simplicity, and a more intentional way of living. This trend extends to electric vehicles (EVs), as individuals like Jeff Droz, a solar off-grid veteran, find the Ford F-150 Lightning EV a versatile companion for fueling with sunshine, running power tools, charging off-grid home batteries, and meeting daily work requirements.
To make the most of renewable energy and minimize costs when charging EVs off-grid, a few key components are essential.
Building Your Solar Power System
A solar power system for off-grid EV charging typically includes:
- Solar Panels: Portable or stationary panels, rated between 100W to several kilowatts, depending on the EV's battery size and desired charge time. For full EV charging, a system capable of several kW is often required.
- Charge Controller: An MPPT (Maximum Power Point Tracking) controller optimizes solar energy harvesting and protects batteries.
- Battery Storage: Lithium batteries store excess solar energy to enable EV charging when sunlight is unavailable.
- Home EV Charger: Level 2 chargers (240V) are ideal for residential solar setups, providing faster and safer charging than basic outlets.
- Smart Charging: Smart chargers or an EV tariff plan can help reduce costs by maximizing charging during solar surplus or cheaper off-peak grid electricity.
- Solar Generators: For remote off-grid charging or backup power, solar generators with 3000W+ output can partially or fully charge EVs, but charging times will be significantly longer due to power limitations.
Cost Minimization Tips
- Invest in a solar battery to store unused solar energy rather than exporting it at low rates.
- Use time-based electricity tariffs where available to charge from the grid at off-peak times and reserve solar energy for direct EV charging.
- Opt for smart charging equipment that automatically schedules charging when solar or low-cost power is abundant.
This approach combines renewable energy use with cost-effective charging tailored to your location and EV specifications.
The Off-Grid EV Experience
Charging an EV off-grid can be a rewarding experience. For instance, Teri Page, a resident of central Vermont, has been living off-grid with an EV for about five years. Her decision to lease a 2020 Nissan LEAF was guided by personal recommendations, affordability, and a desire to shift away from the growing costs of maintaining a gas-powered vehicle.
Teri's off-grid setup includes nine 310-watt solar panels and two 48-volt batteries. During sunnier months from March through October, home charging is simple and often completely free. However, winter brings less daylight and more energy competition between the home's power needs and charging the LEAF, making consistent charging a challenge.
When home solar is not enough, the local network of public charging stations becomes essential. Most of the chargers in her area are Level 2, with one Level 3 station offering a faster, though more expensive, solution. Charging from home solar can feel really rewarding and adds to the sense of security that comes from not worrying less about costs.
In conclusion, living off-grid with an EV is a sustainable and cost-effective choice for those seeking a simpler, more intentional lifestyle. With careful planning and smart investments in solar power systems and charging equipment, you too can enjoy the independence and satisfaction that come with fueling your vehicle with sunshine.

- Implementing a solar power system for home-and-garden purposes could include solar panels, a charge controller, battery storage, a home EV charger, smart charging, and even portable solar generators for remote charging or backup power.
- To minimize costs when charging electric vehicles off-grid, investing in a solar battery for energy storage, optimizing solar energy use with time-based electricity tariffs, and employing smart charging equipment can be beneficial. This approach combines renewable energy use with cost-effective charging tailored to the location and EV specifications, leading to a satisfying off-grid lifestyle experience.
