Rankings Specs Methodology FAQ

If you've got solar panels on your roof, the right EV charger can let you charge your Tesla for free during daylight hours. Solar diversion chargers monitor your panel output in real-time and automatically route surplus energy to your car instead of exporting it to the grid at a fraction of the rate you'd pay to import.

The difference is significant: exporting surplus solar typically earns you 4–5p/kWh through the Smart Export Guarantee, but using that same energy to charge your car saves you 24p/kWh (or 7p/kWh on an off-peak tariff). That's a 5–6x better return on your solar investment.

This guide ranks the best EV chargers for solar panel owners in the UK, based on solar diversion capability, ease of setup, and overall value.

№ 01Top pick

myenergi Zappi GLO

The Zappi GLO is the gold standard for solar EV charging in the UK. Its built-in CT clamp monitors your solar generation in real-time and automatically diverts surplus energy to your car. Three charging modes (Eco, Eco+, and Fast) let you choose between pure solar, solar-plus-grid, or full-speed charging. The Eco+ mode is particularly clever — it uses only surplus solar, dropping to zero when generation dips. No other charger matches this level of solar integration.

The Wallbox Pulsar Max offers solar charging through its Eco-Smart feature, which integrates with compatible solar inverters to optimise charging from surplus generation. It's not as seamless as the Zappi's built-in CT clamp approach — you may need additional hardware depending on your inverter — but the 5-year warranty and compact design make it a strong option for solar households.

The Ohme Home Pro added solar diverting in a 2025 firmware update. While not as sophisticated as the Zappi's dedicated solar modes, it does the job for most solar households and retains the direct-API smart tariff integration Ohme is known for. If you want both solar charging and automated off-peak tariff optimisation in one unit, the Ohme is the best combination.

Rated 4.3/5

Best for battery storage

7kW·Tethered (Type 2)·3 years warranty·Install £400–600£500 grant eligible

The GivEnergy EV Charger integrates seamlessly with GivEnergy's solar and battery ecosystem. If you already have GivEnergy solar panels or a GivEnergy battery, this charger communicates natively with your existing system for optimised solar charging. The integration is excellent within the GivEnergy ecosystem, though less flexible if you have a different inverter brand.

How We Ranked Solar Chargers

Our solar charger rankings prioritise:

Solar diversion quality (35%) — How effectively the charger diverts surplus solar energy, minimum diversion threshold, and response time to generation changes
Setup simplicity (20%) — Whether solar monitoring is built-in (CT clamp included) or requires additional hardware/apps
Smart features (20%) — Tariff integration, scheduling, and the ability to blend solar and grid charging intelligently
Value for money (15%) — Price relative to solar-specific features
Build quality (10%) — Weatherproofing, warranty, and long-term reliability

We tested solar diversion with typical UK residential solar arrays (3–4kW systems) to ensure our recommendations reflect real-world UK conditions, not lab specs.

Maximising Solar Charging

How Solar Diversion Works

A solar diversion charger uses a CT (current transformer) clamp on your electricity meter to measure how much energy your panels are generating versus how much your home is consuming. When there's surplus generation, the charger automatically starts charging your car with the excess — effectively giving you free fuel.

Minimum Diversion Thresholds

Most EV chargers have a minimum power draw of around 1.4kW (6A). This means your solar panels need to be generating at least 1.4kW of surplus energy before the charger will kick in. On cloudy days or with smaller solar arrays, you may not always hit this threshold. The Zappi GLO handles this best with its ability to trickle-charge at lower thresholds.

Solar + Smart Tariff = Maximum Savings

The ideal setup is a solar-compatible charger on a smart tariff. During the day, your car charges for free from solar. Overnight, it tops up at off-peak rates (7p/kWh). This combination can reduce your annual charging costs to under £100. See our smart charger guide for tariff-optimised options.

Battery Storage

If you have a home battery (Tesla Powerwall, GivEnergy, etc.), you can store surplus solar during the day and charge your car from the battery overnight. This works with any charger — you don't need solar diversion built into the charger itself. However, a dedicated solar charger is still more efficient for direct solar-to-car charging.

For detailed per-mile cost comparisons across all tariff options, see the UK EV Charging Cost Index.

Common questions

Frequently asked

Yes, with the right charger. A solar diversion charger like the Zappi GLO automatically routes surplus solar energy to your Tesla. On sunny days, a typical 4kW UK solar array can add 15–25 miles of range for free. Over a year, solar charging can cover 30–50% of a typical driver's charging needs.

The myenergi Zappi GLO is the best solar EV charger in the UK. Its built-in CT clamp and three charging modes (Eco, Eco+, Fast) offer the most sophisticated solar diversion available. The Indra Smart Pro is a strong, more affordable alternative.

You need a charger with solar diversion capability to automatically charge from surplus solar. Without it, you'd need to manually start and stop charging when the sun is out. The Zappi GLO, Indra Smart Pro, and Wallbox Pulsar Max all offer this feature.

A 4kW solar system (around 10 panels) can generate enough surplus energy to add 15–25 miles of range per sunny day. For full daily charging needs (30–40 miles average), a larger 6–8kW system is ideal. Even a small solar array provides meaningful free charging over the year.
