The Smartest Way to Power Your Home and Electric Vehicle
More homeowners are switching to electric vehicles and looking for a practical way to keep charging costs down. For many, the strongest option is a solar PV system with battery storage and a smart EV charger, designed to work together around their home, driving habits and energy use.
A complete solar battery and EV setup allows you to generate your own electricity during the day, store any surplus energy and use it to charge your electric vehicle whenever suits you – even after the sun has gone down.
SolarTherm UK has been designing and installing solar energy systems for more than 16 years across Essex, Kent, Suffolk, Hertfordshire and the wider South East and East Anglia. As an MCS certified and NICEIC approved installer, we help homeowners design systems that make better use of the electricity their panels generate.
What Is a Solar Battery and EV Setup?
A solar battery and EV setup combine four key components:
- Solar panels
- Hybrid inverter
- Home battery storage
- Smart EV charger
Together, they work as one intelligent energy system. During daylight hours, your solar panels generate electricity for your home. Any surplus electricity can either charge your home battery, charge your electric vehicle or be exported to the National Grid for payment via the Smart Export Guarantee (SEG).
Using a solar battery and EV charger together can lower charging costs, reduce reliance on the grid, make better use of the electricity your panels generate and cut the carbon impact of everyday driving.
How Solar EV Charging Works
A smart EV charger communicates with both your solar inverter and your home’s electricity usage. Rather than simply charging your car whenever it’s plugged in, intelligent chargers can monitor how much surplus solar electricity is available.
When your home isn’t using all the electricity your solar panels are generating, the charger increases charging speed. If household demand increases, the charger automatically adjusts, ensuring your home has priority. This intelligent balancing helps maximise self-consumption and reduces imported electricity.
Why Add a Home Battery?
Without battery storage, excess solar energy generated during the day is often exported to the grid. While export payments are useful, buying electricity back later in the evening usually costs considerably more than what you are paid for your surplus.
A home battery gives you another option.
Instead of exporting surplus electricity immediately, your battery stores it for later use. That stored energy can then power:
- Your home after sunset
- Evening EV charging
- Overnight household electricity
- High demand appliances
This means you’re using far more of the electricity you generated yourself. For many households, battery storage dramatically increases overall solar savings.
Benefits of a Solar Battery and EV Setup
- Lower Charging Costs: charging an EV using grid electricity can quickly become one of the largest additions to household energy bills. With solar EV charging, much of that electricity comes directly from your roof. Over the lifetime of your system, this can save thousands of pounds in fuel costs.
- Greater Energy Independence: every unit of electricity you generate yourself is one you don’t need to buy from expensive suppliers. Adding battery storage means you’re less affected by fluctuating energy prices and future price rises.
- Maximise Your Solar Investment: without battery storage or a smart solar charger, some homeowners export more electricity than they use. Adding both allows you to consume much more of your own renewable energy, improving the overall return on investment.
- Reduced Carbon Emissions: driving an electric vehicle already lowers emissions. Charging it using clean solar electricity reduces your carbon footprint even further, making your transport genuinely renewable.
Choosing the Right Solar Charger
Not every EV charger is designed to work with solar panels. If your goal is maximum savings, it’s important to choose a charger with dedicated solar charging functionality.
At SolarTherm UK, we install trusted smart charging solutions by Project EV or myenergi Zappi. These intelligent chargers offer features such as:
- Solar only charging
- Eco charging modes
- Scheduled charging
- Off peak tariff integration
- Remote monitoring through smartphone apps
- Automatic switching between solar power and grid power
The right charger depends on your property, solar array size, battery capacity and driving habits. Our experienced design team can recommend the most suitable option for your home.
Is Battery Storage Worth It?
For many homeowners across Essex, Kent, Suffolk and Hertfordshire, battery storage can be a valuable addition to a solar installation because it allows more of the electricity generated during the day to be used later.
The benefits include:
- More self-generated electricity
- Less reliance on expensive grid electricity
- Greater protection against rising energy prices
- Increased solar self-consumption
- Better overall return on investment
Every property is different, so the best results come from a system designed around the way you use energy.
Can You Add Battery Storage Later?
Absolutely. Many homeowners install solar panels first before adding battery storage and a solar charger later. Modern hybrid systems are designed with future expansion in mind.
If you’re planning to buy an electric vehicle in the next few years, it’s worth mentioning this during your solar quotation so your system can be designed accordingly. Future proofing your installation now can save time and installation costs in the future.
Why Professional Installation Matters
A solar battery and EV charging system is more than simply connecting products together. To achieve the best performance, your installer needs to consider:
- Solar panel generation
- Household electricity usage
- EV charging patterns
- Battery capacity
- Inverter sizing
- Electrical safety
- Future expansion
Poor system design can reduce efficiency and limit long term savings. At SolarTherm UK, every installation begins with a detailed survey and tailored system design. Our qualified engineers ensure every component works together efficiently, helping homeowners maximise energy production and long term performance.

Frequently Asked Questions
Yes, depending on your solar generation, battery capacity and driving mileage. During sunny months, many homeowners can complete a large proportion of their EV charging using solar energy alone.
No, but battery storage allows you to save excess solar energy generated during the day and use it later, making your solar EV charging system even more efficient.
Smart chargers such as Project EV and Zappi are designed to prioritise excess solar energy, helping maximise self-consumption and reduce electricity costs.
In many cases, yes. Adding battery storage allows you to use more of the electricity your solar panels generate rather than exporting it to the grid, improving overall savings.
Savings vary depending on your home’s electricity usage, solar generation and driving habits. A professionally designed system can significantly reduce both household electricity bills and EV charging costs over its lifetime.
