Charging your EV with solar panels

Solar panels and electric vehicles are an energy efficient charging solution

Each solar panel in a solar PV system will typically produce about 355W of energy in conditions of strong sunlight. So you'll get about 30 miles of driving for each hour of charging with our 7.4kW charger.

The amount of solar energy that may be used to charge an electric vehicle will, of course, vary depending on the season and the weather. You might need to use electricity from the grid to complement your solar PV system during the winter months, when there is less daylight and greater cloud cover. But even if you only partially charge your car, solar energy is an effective way to charge an electric car in a sustainable way.

Harnessing solar power to drive sustainability and savings

At a time when we're embracing the transition to electric vehicles (EVs), customers are looking for innovative ways to power their cars while reducing their energy use and carbon footprint. With the advancements in solar panel technology and their increased affordability, integrating a solar panel package with a standard home EV charger offers a sustainable solution. We'll let you know the benefits of using solar panels for car charging, highlight the advantages of battery storage, and let you know about our solar and EV package that'll help you become more sustainable and make savings in the long term.

Reasons to go solar with your electric car

Environmental benefits

By generating clean, renewable energy from the sun, you'll reduce the carbon emissions associated with charging an EV. By embracing solar-powered EV charging, you'll produce clean, renewable energy, helping to combat climate change.

Cost savings

Generating your own energy will lower your energy costs and the cost of charging your EV. The savings you make from generating your own solar power will offset the initial cost of your solar package, leading to long-term savings. 

Energy independence

Solar panels enable you to generate your own electricity, reducing your dependence on the grid. If you add battery storage to your package, you can have a reliable power supply for your home and EV.

How many solar panels do I need to charge my EV?

Larger EV batteries normally need more panels. On average, a solar panel system with around 8–12 panels can charge an electric car, but this all depends on the model of your car and how much sun the solar panels have captured. So, it makes sense to speak with our team of solar experts about the size and type of system you need if you intend to install a solar PV system that you want to use for charging your EV.

Solar & EV charging FAQs

When can I get my charger installed?

As soon as your solar panels are fitted, we'll arrange a convenient time to come and install your EV charger.

Which EVs are compatible with the charger options?

All electric vehicle types are supported by our charger options. 

You only offer a 7.4kW charger but my vehicle's charging capacity is lower than this. Can I still get a 7.4kW home charger?

7.4 kW (32A) is the fastest charger that can be installed on the single-phase electric supply found in most British homes. While some vehicles are limited to slower charging rates, they can still be connected to 7.4 kW fast charger as the vehicles on-board charge controller will only charge up to its maximum charging rate. We only offer a 7.4 kW charger as these will ‘future proof’ your installation, allowing for changes to your electric vehicle. You might not be able to now, but in the future, it is likely you’ll be able to charge faster.

Is the UK sunny enough for solar panels?

In contrast to its reputation, the UK receives plenty of solar energy, making solar panels a worthwhile investment for your home, even during overcast days. Surprisingly, the UK receives a comparable level of solar energy to certain warmer European nations, including Germany, a global leader in solar power generation.

Is planning permission necessary for solar panels?

Installing solar panels on your home falls under the category of "Permitted Development," meaning that typical solar panel setups do not necessitate planning permission. However, if your residence is listed, situated within a world heritage site, or if the installation deviates from standard guidelines, then obtaining planning permission is advised.

Can solar panels be installed on my roof?

Regardless of whether your roof is oriented towards the south, east, or west, it is well-suited for solar panel installation. North-facing roofs, however, might experience reduced sunlight exposure, resulting in lower efficiency. The ideal roof pitch for installation ranges between 20 to 50 degrees.

The legal stuff

* E.ON Next already supplies customers with 100% renewable electricity. Those on the E.ON Next Drive Fixed tariff can even charge their EVs at the lowest rates, (between midnight and 7am at 9.5p per kWh.) Electricity backed by 100% renewable sources, E.ON's renewable generation assets, agreements with UK generators and the purchase of renewable electricity certificates. The electricity supplied to your home or business comes from the National Grid and DNOs.

1: Price is based on a 6 Panel “Energise” package (on-roof), fitting to concrete tiles (not slate), single elevation of scaffold, with single-phase electrics, and no complexities, for example installing above a conservatory or digging trenching required for electrics.

2: Solar panels and savings are subject to eligibility requirement, geographical restrictions and terms and conditions.

3: These are example figures only, based on standardised MCS calculations. Savings are based on property fitted with a south-facing solar array in central England on a roof with a 35-degree tilt and no shading, with electricity consumption of 4,800 kWh per year (with the customer Home all day), at a tariff rate of 24.5p/kWh. The solar array contains 12 x 435W panels (5.22 kWp) generating 4,881 kWh/year, fitted with a 5.1 kWh (5.1 kWh usable) battery.

4:  Smart Export Guarantee (SEG) payments, are payments for electricity you export to the grid. These savings figures are based on the Next Export Exclusive Premium tariff from E.ON Next of 25.0p per kWh (kilowatt hour) for E.ON Next import-tariff customers who purchase a solar-only solution. For E.ON Next import-tariff customers buying a solar and battery combined package, the Next Exclusive Premium Plus Export rate is 40.0p per kWh.
