How Much Battery Storage Does a 3-Bed Home Need?
For a typical 3-bedroom home in Bristol, battery size depends on daily energy use, solar generation, and whether you're aiming for full or partial self-sufficiency.
Most 3-bed homes will need a 5kWh to 10kWh battery — but it’s not one-size-fits-all. Let's break it down:
Average Energy Use for a 3-Bed Property
The average electricity usage in a 3-bedroom house is around 8–12 kWh per day.
- If you're home during the day, solar can power appliances directly.
- Evening and overnight usage (e.g. lighting, heating, devices) can be covered by a battery.
How to Choose the Right Battery Size
We recommend:
- 5–7 kWh battery – Suitable for modest evening use or part-time occupancy.
- 8–10 kWh battery – Ideal for families or full-time working households.
- 10+ kWh battery – Best for those aiming for full energy independence or using high-draw items like EV chargers or heat pumps.
Zero Export Options for Bristol Homes
All our solar installations use zero export technology, which stores excess energy in a home battery instead of sending it to the grid.
- Works great for households without grid export permissions.
- Ensures maximum use of your solar energy — not the utility company’s!
