Solar and electric vehicles

About solar and electric vehicles

Solar owners in Maryland went solar with us and added an electric vehicle.

Electric vehicles (EVs) are quickly becoming a more affordable, 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

EV chargers are classified into three categories: level 1, level 2, and level 3 (DC Fast charging). The categories are defined by the power and rate at which they charge a vehicle, and the electric infrastructure required for installation and operation.

Solar + EVs: A great combo

Solar United Neighbors sees electric vehicles as a logical next step for solar owners. Once you go solar you can power your car with your own, cheaper solar electricity.

We’re helping our members adopt electric vehicles and fight for better state and federal incentives, progressive pilot projects, and fair charging rates.

Solar producers and EV owners want to be part of the solution, creating a more sustainable, resilient and affordable electric system. The beauty is that we can rely on ourselves and our private investments to help drive change.

Our work

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.

We are developing work and partnerships to help our members get electric vehicles and fight for good policy in many states. In Ohio, our Appalachian Solar Co-op included EV chargers for every house that went solar at no additional charge.
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.
