Which Solar Panel System Works Best with EV Charging?
Introduction
As electric vehicles (EVs) become the future of personal transport, many UK homeowners are turning to solar panels for EV charging to drive cleaner, greener, and cheaper cars. Pairing a home solar system with an EV charger not only reduces your reliance on the grid but also makes every mile powered by renewable energy. But with so many solar setups available, how do you know which system works best for your EV?
This guide breaks down the best solar solutions, helping you choose the most efficient and cost-effective setup for your electric vehicle and your home.
How Solar Panels Power EV Charging
Before exploring the best system, it’s important to understand how EV charging with solar works. When sunlight hits your panels, the photovoltaic (PV) cells generate direct current (DC) electricity. This is then converted into alternating current (AC) by an inverter, allowing it to power your home appliances and your EV charger.
By connecting your solar EV charger to your home solar system, you can:
- Charge your car directly from solar energy.
- Reduce grid electricity usage and costs.
- Lower your carbon footprint with clean, renewable energy.
For instance, a 4kW solar panel system can generate around 3,400–4,000 kWh annually enough to cover most of the energy needs for an average EV driver in the UK.
Choosing the Best Solar Panel System for EV Charging in the UK
When it comes to selecting the best solar panel system for EV charging UK homeowners have several factors to consider:
1. Solar Panel Efficiency
The efficiency of your panels determines how much sunlight gets converted into usable energy. High-efficiency panels (such as monocrystalline types) are ideal for smaller roofs, producing more power per square metre, perfect if you want to maximise your charging potential.
2. Battery Storage Integration
Pairing your solar array with a battery storage system allows you to store excess solar energy for later use. This means you can charge your EV even after the sun goes down. McNally EV offers advanced battery storage solutions that integrate seamlessly with both solar panels and EV chargers, optimising your home energy flow.

3. Smart Solar Systems
Today’s smart solar systems use intelligent software to manage energy usage automatically. They prioritise powering your EV when solar generation is high, reducing reliance on the grid. Some systems can even communicate with your EV charger to optimise charging times for maximum efficiency.
4. Compatible EV Charger
Not all EV chargers are created equal. A solar EV charger is designed specifically to integrate with your solar setup, adjusting charging speed based on available solar power. McNally EV installs a range of smart chargers from leading brands like MyEnergi, Wallbox, and Ohme, ensuring the perfect match for your solar system.

5. System Size and Roof Space
A typical home solar system for EV charging ranges between 3kW and 6kW. The ideal size depends on your roof space, budget, and driving habits. For example, if you drive 10,000 miles annually, a 5kW system could supply most of your EV’s charging needs, significantly cutting electricity costs.
Cost of Solar Panels for EV Charging
The cost of solar panels for EV charging varies based on system size, brand, and installation complexity. On average, UK homeowners can expect to invest between £5,000 and £9,000 for a standard residential solar setup.
Adding a battery storage system can increase upfront costs but delivers long-term savings by enabling off-peak charging and grid independence. Furthermore, the UK’s Smart Export Guarantee (SEG) allows you to earn money by exporting excess solar power back to the grid, reducing payback time.
