Solar PV and Battery Storage: Should You Invest in Both?

Introduction

Solar panels generate clean electricity during the day. But what about at night? That’s where battery storage comes in—and for many homeowners, it’s the key to maximising the value of a solar system.

How Solar Batteries Work

A solar battery stores unused electricity generated during the day. This stored energy can be used later when solar production drops, like in the evening or on cloudy days.

Benefits of Adding Battery Storage

• Increased self-consumption: Use more of the energy you generate
• Lower bills: Reduce electricity bought from the grid
• Energy independence: Protection against rising energy prices
• Grid resilience: Some systems offer backup during outages

Costs and Payback

• Battery costs: £2,500–£4,500 (depending on size)
• Payback: Typically 8–14 years, depending on usage patterns and SEG earnings

Is It Right for You?

Battery storage is ideal if:

• You're home during evenings
• You want to maximise return on solar investment
• You prefer greater control over energy use
