Solar, battery or EV charging — find your fit
Solar panels help you generate your own electricity. Adding a battery or smart EV charging lets you use even more of it. Some homes start with panels alone; others plan the full system from day one.
Solar panels
Best for homes with a suitable roof and electricity use that can be shifted into daylight hours.
- Roof direction, space and shading
- Battery storage interest
- Electricity use during day and evening
- Budget, grants and eligibility
Solar and battery
Best for homes that want to store daytime generation and use more of their own solar energy.
- Daytime vs evening electricity use
- Battery capacity to match your usage
- Backup power during outages
- Budget, grants and eligibility
Solar with EV charging
Best for homes ready to charge an electric vehicle from their own clean energy.
- Roof suitability for solar panels
- Smart EV charger compatibility
- Daytime charging patterns
- Budget and available grants
Frequently asked questions
It depends on your home's current energy use. Solar panels are usually the first step for homes with suitable roofs, as they reduce electricity costs directly. Adding a battery improves self-consumption by storing daytime generation for use in the evening, so many homes start with panels and add storage later.
Your panels generate the most electricity in the middle of the day, often more than you use at the time. A battery stores that surplus instead of exporting it, then releases it in the evening and overnight — so you rely far less on the grid.
Yes. Panels generate from daylight, not direct sunshine, so they still produce power on overcast days — just at a lower output. A well-sized UK system is designed around realistic year-round conditions, not just sunny days.
Yes. With a compatible smart EV charger, your car can charge from surplus solar generated during the day, cutting your charging costs significantly. Pairing solar with a battery lets you store daytime energy to charge in the evening too.
Solar panels typically cost £5,000–£9,000 for a domestic system, and adding a battery generally adds £2,000–£5,000 depending on capacity. Use our free estimate tool to get a personalised quote for your home.
