From San Francisco, CA - VP of Tesla owners Silicon Valley
“For me, solar charging is a long-term investment which just makes sense. I’m busy with work and life at home, but it’s important for me to charge with the cheapest energy."
"That’s why ev.enegy is great. I’m able to charge at the most optimal time of the day with solar energy, so I don’t have to charge from the grid... I know that the investment I’ve made in ev.energy SOLAR will pay for itself within a matter of months.”
The ev.energy app works with the top electric vehicle and EV charger manufacturers. No need for extra hardware.
EV drivers everywhere love using the ev.energy app. Here’s why.
Saving money: This app is great it’s easy to use and it gives you points for charging off peak hours, this app is so easy to use a five-year-old could figure it out with no problem

Excellent I have to track my monthly electricity going toward my Tesla for my rent and couldn’t do so without this app. I don’t know why people are giving it bad reviews because my experience has been positive.

Impressive and getting regular improvements Been using the app for a couple of years with my Model 3 and apart from occasional teething troubles initially we now rely on it to get the cheapest charges possible from our Agile Octopus tariff.

Fantastic! We’ve been so impressed with this app. It works well 99.9% of the time. However, most impressive is their response when there has been an issue. We’ve emailed and had a quick response. These guys haven’t put a foot wrong.

Excellent Excellent app; exactly what I was looking for. Our TOU rate doesn’t get cheap until 9:00pm, when I want to be watching TV, not going in the garage to plug the car in. The app makes sure the charging happens overnight.

ev.energy’s Solar Smart system calculates the best time to charge your vehicle based on your electricity tariff and your solar panel output, as well as when greener electricity is available from your supplier.
Solar Smart uses a highly accurate solar irradiation forecasting algorithm to optimise your charge for when it's cheapest and greenest, considering: your tariff, the carbon forecast, and your solar panel output. The algorithm predicts how much power your solar panels are producing and then schedules your charging accordingly. See "How does Solar Smart Charging calculate the best time to charge?"
Solar Smart is a software-only solution. Using a software-based approach means that users do not need to have any specific hardware. It also means that we can make it available to all our users irrespective of their location.
To enable users to charge with only the solar power they are producing, we vary the charge rate of the vehicle to match the power produced. We can do this in two different ways;
1. Users with a hardware-based solution have a CT Clamp installed around their meter inlet. This lets the charger see the amount of power being imported or exported to the grid. This means that household load is taken into account as we are looking at the total power going into or out of the house.
2. Users without any hardware installed can use our software-based solution. We use a solar irradiance forecast which provides an estimation of the solar power produced by a solar array.
Using this information the charger can vary the amount of power available for the vehicle and so ensure that no energy is imported or exported. Both of these solutions will allow users to have zero cost, zero carbon charging however a hardware solution will typically be more accurate.
Your solar panels need to be exporting more than 1400w to the grid for your car to charge. If they are producing less, then no charge will go into your car. This means that the total power produced minus the household load needs to be greater than 1400w
You can override Solar Charging settings at any time. Just hit the Boost button in the app, then your car will get an immediate charge - perfect for those last-minute changes of plans when you need a little extra juice to get on your way.
