Commercial Solar Battery Storage

Why get battery storage for your business?

Energy prices are continuing to get more expensive! In January 2026, the energy bill price cap went up again to £1,758.

Ongoing global instability, and the UK’s reliance on imported energy, means that the future cost of energy is uncertain.

Commercial Battery Storage puts your business back in control. If you have solar panels, you’ll boost your business’s self-consumption by up to 40%. When you do need to buy from the grid, you can buy cheaper energy overnight for as little as 6.7p/kWh, store it in your battery, then use it during the day.

Not to mention thanks to our partnership with Axle Energy, Sunbright Energy customers have access to export rates of £1/kWh. Read more about that here.

Solar battery FAQs

How does a solar battery work?
Charging by solar panels: Your solar panels turn sunlight into electricity. Some of this directly powers your home, while the rest flows to your solar battery.

Storage: The battery’s advanced chemistry stores this excess power, ready for when you need it.

Home usage: At night, during cloudy weather, or when demand is high, the battery releases its stored energy to keep your home running smoothly.
What size battery do I need?
The perfect battery size depends on:

Your energy habits: We’ll analyse your energy bills to understand your typical power usage.

Your backup goals: Do you want essential appliances to run during a blackout or your entire home?

Sunbright Energy experts can help you pinpoint the ideal battery capacity.
Will a battery protect me during a power cut?
Yes, it can! Here’s what you need to consider:

Battery size: A larger battery can power your home for longer during an outage.

System design: Our specialists can design a solar-plus-battery system that allows for backup operation when the grid goes down.
What is the lifespan of a solar battery?
Sunbright Energy uses top-quality batteries expected to last between 5 and 15 years. Factors influencing lifespan include:

Battery technology: We favour reliable lithium-ion batteries known for their durability.

How you use it: Frequent deep discharging can shorten battery life.

Expert maintenance: Our maintenance plans help maximise your battery’s lifespan.
