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.
