Solar owners are sending too much cheap power back to the grid — often for nothing. With Gridio’s smart solar EV charging, you can self-consume more, save money, and help the grid. No extra hardware needed.
Across Europe, rooftop solar is booming and nearly 50% of EV drivers have their own solar panels. Homeowners are producing more electricity than ever—but there’s a problem. Much of that solar energy is being sent back to the grid, often for minimal or, in case of negative electricity prices, even negative financial return.
It doesn’t have to be this way. There’s a better place to send your sunshine: your electric car.
Gridio now makes it easy to turn your EV into a smart battery on wheels for your excess solar. It’s a simple, powerful way to increase self-consumption, save money, and reduce pressure on the grid—all with no extra hardware required.
Two Big Solar Challenges
The solar boom creates two challenges:
The first is financial. During peak solar hours, export prices can drop to just a few cents per kilowatt-hour—or even go negative. That means you’re often giving away your valuable solar energy for almost nothing.
The second is ‘grid-technical’. As more homes push solar into the grid at the same time, local infrastructure struggles to keep up. Distribution networks weren’t designed for such high volumes of simultaneous export, and the resulting congestion is a growing issue, in turn putting upward pressure on grid fees.
Solar to your EV battery, dynamically!
Gridio’s Solar Charging feature helps you avoid both of these problems by automatically using your excess solar to charge your EV. There’s no hardware, no manual toggling, and no electrician visit required. Just pair your car and your inverter through the Gridio app, and the system takes care of the rest.
Now we are introducing Dynamic Solar Charging, which goes beyond the standard “on/off” model most systems use. Gridio dynamically adjusts your car’s charging power to match your real-time solar generation or inverter export data.
If you have plenty of excess solar at your home, Gridio charges your car with higher power. If clouds roll in or home usage increases (if you have a smart meter connected inverter), the charging adjusts accordingly—automatically, and in real time, directly through the app.
This approach is more efficient, more flexible, and doesn’t require you to do anything beyond a one-time setup.
Vehicles supported: Tesla - full power modulation, VW & Škoda - partial modulation, with other brands currently following the previous on/off logic.
Inverter brands supported: SolarEdge, SMA, Fronius, Huawei, Ferroamp, Growatt, Kostal, Sofar, Solax, Solis, Sungrow and we're constantly adding more!
What You Save, and Why It Matters 🌍
Charging your car with solar you’d otherwise export brings a double benefit.
First, it saves you money. You avoid having to import electricity later, often at higher rates — and you skip grid fees, which can be significant depending on your country.
Second, it helps balance the grid. By consuming your solar energy when it’s available, you reduce both export spikes during the day and demand surges in the evening.
For many users, these benefits can add up to €100 or more in annual savings — with zero change to daily routines.
Getting Started is Easy 📱
Here’s how simple it is to get going:
- Connect your EV and solar inverter to Gridio.
- Define your preferred solar-charging limit.
- Sit back and let Gridio handle the rest. Whenever your solar panels generate more electricity than your household uses, Gridio automatically directs that surplus energy to charge your EV.
No hardware. No installers. Just smart use of what you already own.
Seize the Sun ☀️
With over 100 million EVs expected on EU roads and a third of EV drivers already owning solar panels, the opportunity for smarter charging has never been greater. Gridio helps you be part of that shift—without lifting a finger.
