Why Add Battery Storage?
Without a battery, excess solar energy during the day is exported to the grid for just 5-15p/kWh. With a battery, you store that energy and use it in the evening when electricity costs 25-35p/kWh - more than doubling its value.
With Solar
Store excess solar generation during the day and use it after sunset. Increase self-consumption from 30-50% to 70-80%+.
- Use your own solar energy 24/7
- Reduce grid imports significantly
- Double the value of excess solar
Without Solar
Charge from the grid on cheap overnight tariffs and discharge during expensive peak times. Works with tariffs like Octopus Go.
- Charge at 7-10p/kWh overnight
- Use at 30p+ peak times
- Save 20p+ per kWh
Additional Benefits
Backup Power

Choosing the Right Battery Size
The ideal battery size depends on your energy usage patterns and solar system size:
| Home Type | Recommended Size | Typical Cost |
|---|---|---|
| Small home / low usage | 3-5 kWh | £3,000-4,500 |
| Average family home | 5-10 kWh | £4,500-7,000 |
| Large home / high usage | 10-15 kWh | £7,000-10,000 |
| EV charging included | 13+ kWh | £8,000+ |
As a rule of thumb, your battery should be able to store half to all of your daily evening electricity usage (typically 4-8 kWh for a family home).
Frequently Asked Questions
Can I add a battery to my existing solar system?
Yes! We can retrofit batteries to most existing solar installations. We'll assess your current system and recommend the best battery solution to integrate seamlessly.
How long do home batteries last?
Modern lithium batteries are rated for 4,000-6,000 cycles, which equates to 10-15+ years with daily use. Warranties typically guarantee 70% capacity after 10 years.
Will my battery work during a power cut?
It depends on the system configuration. Some batteries (like Tesla Powerwall) include backup functionality as standard. Others need additional hardware. We'll advise on the best option for your needs.
Is battery storage worth it without solar?
Yes, if you're on a time-of-use tariff like Octopus Go. Charging overnight at 7-10p/kWh and using during the day at 30p+ saves significant money. With larger price differentials, payback can be 5-7 years.
Where will the battery be installed?
Batteries are typically installed in garages, utility rooms, or externally (weather-permitting). They require a flat surface and adequate ventilation. We'll recommend the best location during your survey.
