Do I need battery storage with solar panels?
Quick answer: Battery storage maximises self-consumption but isn't essential. Many add it later.
Battery Storage: Do You Need It?
Battery storage isn't essential for a solar system, but it can significantly increase your savings and energy independence. Here's how to decide.
Benefits of Battery Storage
- Higher self-consumption: Use 70-80% of your solar instead of 30-40%
- Evening power: Use stored solar energy after sunset
- Power cuts: Some systems provide backup power
- Reduced grid reliance: Greater energy independence
- Time-of-use tariffs: Store cheap rate electricity for peak times
When Battery Makes Sense
- You're out during the day and use most electricity in evenings
- You want to maximise self-sufficiency
- You have variable rate electricity tariffs
- Power cuts are a concern in your area
When to Wait
- You're home during the day and can use solar directly
- Budget is limited — panels alone still save money
- You want to add battery storage later when prices drop
Retrofit-Friendly Design
We design all our systems to be battery-ready, making it easy and cost-effective to add storage later if you choose not to include it initially.

All package prices assume every panel fits on a single roof elevation. The price covers the cost of scaffolding to one elevation. If your roof needs scaffolding on more than one elevation, or has restricted access, that additional cost is quoted separately after survey. Prices include VAT. Domestic solar and battery storage is zero-rated for VAT until 31 March 2027. Subject to a free technical survey. We will confirm the final price in writing before any work is booked.
