Unlock Complete Energy Independence
Solar panels generate clean energy, but without a battery, much of it is sent back to the grid for little money. A battery storage system saves that extra energy for times when the sun is not out. With a battery, you can power your home at night, on cloudy days or even during blackouts, making your solar panels much more useful.
Benefits of Battery Storage
- Energy independence & security: Store solar energy made during the day and use it whenever you need, so you depend less on the grid and have backup power.
- Lower electricity bills: Use stored energy when electricity is most expensive; many households save hundreds of pounds each year.
- Get the most from your solar panels: A battery ensures all the energy you generate is used by you, not sent back to the grid.
- Environmental benefits: By using more of your own clean energy, you depend less on oil and gas.
- Smart tariffs & grid use: Some systems let you charge your battery with cheap electricity at night and use or sell power back when prices are high.
- Increase property value: Homes with solar panels and batteries often sell for more because they cost less to run and are better for the environment.
Integrated Solar, Battery and EV Charging
Battery storage is the final piece for clean energy at home. When you have solar panels, a battery, and an EV charger, your extra solar energy can power both your home and your car. You will use more of your own energy, pay less for electricity, and help the environment.
Choosing the Right Battery
We tailor every system to your needs. Typical recommendations are:
1–2 bedroom flat | 5–8 kWh/day | 4–5 kWh |
3–4 bedroom home | 9–12 kWh/day | 6–10 kWh |
5+ bedroom home | 13–18 kWh/day | 10–14 kWh |
Most homes use batteries with a capacity of 5–10 kWh, which is enough for typical day-to-day needs. Choosing a slightly larger battery gives you space for future upgrades, such as EV chargers or heat pumps. During your site visit, we look at how much energy you use and design a system that fits your needs and budget.
