Now in preview | Launching March 2023
Use our app to enjoy zero-cost, zero-carbon, solar-powered EV charging without costly hardware upgrades.
If you’ve invested in home solar panels, or are just about to, this one’s for you.
Our app has two solar options that make it easy to soak up the sun.
Solar Only
Ramp the electric current of your charge up or down to meet your self-generated solar output for a truly zero-cost, zero-carbon without using energy from the grid.
Works with Indra, waEV-charge and Rolec chargers.
More integrations coming soon.
Solar Smart
Charge with Solar Only when the sun is shining, then pull in grid energy when required to ensure a full charge. You get the cheapest, greenest charge every time, guaranteed.
Works with all compatible cars and chargers.
Add your details and find out how much money you could save by Solar Charging.
Our calculations are based on the average miles driven by a UK driver, national energy pricing statistics and data averages from the 4 million + charging sessions that have taken place through the ev.energy app between 01 January 2020 and 01 July 2022. See a full breakdown of the data that makes up this saving calculation below.
Smart Charging Savings
Smart charging savings are calculated by showing how much money you save on your energy consumption using ev.energy’s technology to shift your charging from ‘Peak’ energy pricing windows to ‘Off-peak’ pricing windows.
Energy Pricing
As of October 01, 2022, National domestic energy pricing has an average of 28.3 pence per kwh. peak and off-peak charging are based on the national average of the Octopus Go tariff. (£0.40 peak rate & £0.075 off-peak rate) Find the rates based on your postcode.
Peak and Off-Peak Times
The most frequent peak times tend to be weekdays between 6pm-9pm, however there is no fixed rule. Off-peak can be at any time, depending on the weather and renewable generation on the grid. In the UK, generally, off-peak is overnight when there is an abundance of wind or around lunchtime at the weekend when the sun is shining. ev.energy take care of tracking this complexity for you, ensuring you always charge and the cheapest and greenest time every day.
ev.energy Technology Capabilities
Through multiple trials and our native app data, we have shown that ev.energy has the capability to shift energy from the average peak service window up to 100% (6pm-9pm). We have based the above calculations on a 97% shift in energy from peak to off-peak pricing (Bloomberg ‘A review of real-world data from ev.energy’s smart charging platform’, October 2021).
Solar Smart Charge Savings
The top 10% of participants in our Solar Beta Trial (N=356) completed an average of 40% of their annual charging using the energy generated from their home solar between 01 June 2022 and 30 June 2022. Our data shows that Solar Smart Charging is effective from March to November based on the average UK solar array. This has been accounted for in our annual savings calculation.
Rewards Earned
ev.energy is paid by energy networks to shift energy consumption from peak to off-peak windows. We give this back to our customers in the form of reward points to spend on their energy bills or through retailers.
Generating Points
ev.energy users generate 1 reward point for every charge over 7kWh.
Redeeming Rewards
You need 15 points to earn £5 in reward points as an ev.energy + user. You will need 30 points to earn £5 in rewards as a regular ev.energy user.
Average Earnings
Using the average UK EV driver, we have taken the average consumption of our 3 million charging sessions.

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.
