Solar Battery Storage in Norwich: Costs, Sizing & Is It Right for Your Home?

Let’s face it, energy bills are only heading in one direction, and it’s not down. If you’re in Norwich and feeling the squeeze, or just looking to make smarter, greener choices, you’ve probably come across solar battery storage. But is it worth the investment? Is it even the right fit for your home?

Good questions. This guide dives into the essentials: costs, savings, system sizes, grants, and throws in a bit of local flavour too. You’ll leave with a clearer idea of whether a solar battery is right for you. Spoiler: it might be.

Who Should Consider Battery Storage in Norwich?

If you’ve already got solar panels on your roof, a battery storage system can make a big difference. During sunny hours, your panels work hard. But if you’re not home to use the energy, it goes back to the grid. That’s nice for the grid, but not so great for your wallet.

A battery lets you keep that extra energy and use it when you need it most. Evening telly? Charging the car? Running the dishwasher after 7pm? Sorted.

You’re a good candidate if:

• You export lots of unused solar energy.
• Your electricity use spikes in the evenings.
• You’re running a home office or EV charger.
• Your roof faces south or gets good sun.

And don’t worry if you haven’t got loads of space, as batteries can be tucked away in garages, utility rooms or even weatherproof units outdoors.

How Much Storage Do You Actually Need?

Here’s the rough maths: most Norwich homes use around 13kWh of electricity a day. That means a 10–15kWh battery usually does the trick.

Aim to cover at least 70% of your usage with stored energy. So, if you’re using 13kWh, you’d want a 9–10kWh battery. Most are modular too, so you can start small and scale up later, especially if you’re eyeing up a heat pump or EV in the future.

Want backup in a power cut? Reserve about 25% of the battery just for emergencies. That way, a 10kWh battery gives you 7.5kWh of regular power and a 2.5kWh safety net.

What Are the Costs and Savings?

We won’t sugar-coat it: battery systems aren’t cheap. But they can pay off faster than you think.

Expect to spend between £5,000 and £8,000, depending on brand, size, and install needs. A solid 10kWh setup might set you back £6,000, but if it saves you £1,000 a year, you’re breaking even in six years.

Add to that 0% VAT (cheers, government!) (source) and it’s suddenly a lot more palatable. We also offer finance options to those that may want it.

Installation Standards and Tech Stuff (The Important Bits)

Let’s talk safety and standards. You want the right kit, installed properly.

We work to PAS 63100 standards and we’re fully MCS certified. Why’s that important? It means your system will be safe, efficient, and eligible for the good stuff…grants, export tariffs and peace of mind.

Our batteries last 10–15 years (or about 6,000 cycles). You can monitor everything via a handy app, including charge levels, usage, and savings. And if the grid goes down? You’ve got backup power ready (if configured for it).

Thinking Ahead: Making the Most of Battery Storage

Battery storage isn’t just about now. It’s about what’s coming next. With the rise in electric vehicle adoption, more people working from home, and an increasing number of smart appliances, our homes are using more electricity than ever before. Having your own energy supply stored and ready helps future-proof your lifestyle.

Pair your battery with a heat pump, solar panels, and a smart tariff, and you’re not just saving money, you’re creating a low-carbon home that runs on your terms. More control. Less waste. A smarter, greener future.

Battery Modes Explained

Modern batteries are pretty clever. Depending on your goals, they’ll switch between different modes:

• Self-Consumption Mode – Uses solar first, grid second. Simple and effective.
• Time-of-Use Mode – Charges at night (when power is cheap) and discharges during the day.
• Backup Mode – Keeps energy in reserve for power cuts.

These settings are easy to manage via the app, and we’ll show you how it all works.

Smart Tariffs: Charge Low, Use High

If you’re on a smart energy tariff like Octopus Agile or Economy 7, your battery system can be even more efficient. These tariffs offer cheaper electricity at certain times, usually overnight. With the right setup, your battery charges when rates are low and discharges when prices go up. That means you can use stored energy during peak hours, saving even more.

We’ll help you configure your system to make the most of your tariff. And don’t worry if it sounds complicated, as once it’s set up, it runs quietly in the background while you get on with your day.

Real-World Example: Cringleford Installation

Early in 2024, we installed a 10kWh GivEnergy system in Cringleford. The homeowners already had solar, used about 13kWh a day, and wanted to reduce their bills while preparing for EV charging.

The result?

• Grid use cut by 85%
• Savings of £750–£900 per year
• Backup power on standby
• Smart tariff use with Octopus Agile

They were thrilled. Quick install, simple controls, real savings.
