Spread the cost with low monthly payments
Pay once and lock in a year of solar charging
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.

Visit our claims and substantiations page to understand how we calculated these figures
Our calculations are based on the average miles driven by an American 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.
All usage statistics are based on an average American EV driver who drives 10,000
miles a year at an efficiency of 3.5 miles per kWh.
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, Californian domestic energy pricing has an average of
$0.39 per kWh. peak and off-peak charging are based on the national average of the
PG&E domestic rate. ($0.42 peak rate & $0.34 off-peak rate) See the documentation
here.
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 USA, 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 takes 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 across the USA with CA offering the ability to solar charge
year-round. Based on the average 6kWh 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 American EV driver, we have taken the average consumption of
our 3 million charging sessions.
These pioneers went the extra mile to help us build Solar Charging for everyone - and made some serious savings along the way.
The ev.energy app works with the top electric vehicle and EV charger manufacturers. No need for extra hardware.
More vehicles and chargers coming soon
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

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.
