Solar and electric vehicles
Solar + Electric Vehicles = A Great Combo
Electric vehicles (EVs) are quickly becoming a more affordable and lower maintenance option than traditional gasoline-fueled cars.
America’s EV adoption rate is quickly rising as more affordable, long-range models are introduced to the market.
For solar owners, the idea of fueling your car with homegrown energy is especially compelling.
Market studies show that “roughly one-half of consumers who have solar or EV technology have both.” Similarly, consumers who are interested in one of these technologies are also interested in the other. Utility planners who forecast how much electricity to provide the grid (i.e. load) will need to consider these findings as technology adoption ramps up.

With their large battery packs, electric vehicles can also potentially become another storage device that grid operators, utilities, and homeowners can leverage to build the distributed grid of the future. For instance, solar producers can charge electric vehicles with excess energy from their solar panels instead of sending that electricity back to the grid, or they can charge their cars at night when electricity is less expensive and in less demand. In a worst case scenario from an energy management point of view, car owners could plug in their cars, right when they return home from work—adding to peak demand and increasing the strain on the grid. In other words, solar panels can help us create a distributed network of energy producers, and electric vehicle batteries may help us create a distributed network of storage. But whether this works to strengthen the grid or put more strain on the grid depends on energy policy.
Many states are piloting programs to study EV owner behavior and learn how to optimally manage the new load source. These pilot projects not only educate utilities, governments, and grid operators on EV customer behaviors, but also offer insights into rate design and infrastructure deployment to balance electricity loads and improve grid stability and reliability.
Electric Vehicle Charging Guide
Solar United Neighbors sees electric vehicles as a logical next step for solar owners and we’re fighting for more EVs by supporting state and federal incentives, progressive pilot projects, and fair charging rates.
- In 2018, our Appalachian Ohio Solar Co-op included EV chargers for every house that went solar at no additional cost.
- We are currently running co-ops in multiple states that are bringing together homeowners and small businesses and giving participants the option of installing solar , a level 2 electric vehicle charger, or both. Find out more details about our open co-ops on our co-ops page.
- In total, we have helped expand access to EV chargers for homeowners in 6 states and 18 co-ops.
- State EV fees – States across the country are introducing bills that would impose unfair and punitive annual fees on electric vehicles. If passed, such legislation would make the operating costs of EVs much greater and would put an additional barrier in the way of deploying a technology that pairs wonderfully with solar.
- In D.C. and Maryland we are involved in cases at the Public Service Commission to establish time-of-use tariffs for electric vehicle owners. We are working to make sure these policies are fair to solar producers and electric vehicles owners. All together, these efforts must add up to a more democratic, affordable and resilient grid.
