Signs You Need Battery Storage — And What To Do Next

Signs You Need Battery Storage – And What to Do Next

Battery storage is no longer just an optional extra for homes with solar panels. For many Devon households—whether it's a Victorian terrace in Paignton, a holiday let on the seafront, or a family home in Torbay—adding a battery can make your energy use smarter, more cost-effective, and more resilient.

Here are the key signs that battery storage could benefit your home, along with a practical guide on what to do next.

1. Your Solar Panels Frequently Export Excess Electricity

If your solar PV system regularly generates more electricity than your home uses during the day, the excess energy is likely being exported to the grid.

Instead of sending that energy away, a battery allows you to store it and use it later, such as during the evening when your electricity demand is higher.

Check your inverter or smart meter export readings—consistent daytime exports are one of the strongest indicators that battery storage could save you money.

2. Your Energy Usage Is Highest During Peak Times

Many households use the most electricity during the evening for:

• Cooking

• Heating

• Entertainment

• Electric vehicle charging

If you're on an Economy 7 or Economy 10 tariff, or you regularly see high evening electricity costs, battery storage allows you to use stored solar energy—or cheaper off-peak electricity—when rates are highest.

3. You Want Backup Power During Power Cuts

If your property experiences occasional power outages due to storms, maintenance work, or a less reliable electricity supply, battery storage can provide valuable peace of mind.

With the right system, essential circuits such as:

• Lighting

• Refrigeration

• Broadband

• Medical equipment

can continue operating during a power cut.

If backup power is important, ask your installer about batteries designed for essential circuit backup.

4. You Charge an Electric Vehicle at Home

Home EV charging can significantly increase electricity consumption.

Pairing your solar panels with battery storage allows you to maximise the amount of self-generated electricity used to charge your vehicle, reducing reliance on electricity imported from the grid.

5. You Want Greater Energy Independence

If your goal is to:

• Reduce reliance on the National Grid

• Protect yourself from rising electricity prices

• Prepare for future technologies such as heat pumps or additional EVs

then battery storage is an excellent long-term investment as part of a wider home energy upgrade.

What to Do Next – A Practical Checklist

1. Gather Your Energy Data

Before requesting quotations:

• Collect the last 6–12 months of electricity bills.

• Download smart meter or half-hourly consumption data if available.

• Make a note of any future plans, such as installing an EV charger, heat pump, or home extension.

This information helps accurately size your battery system.

2. Check Your Existing Solar Installation

Find out:

• The size of your solar PV system.

• The age of your inverter.

• Whether your inverter is battery compatible.

Older systems may require a hybrid inverter or additional equipment.

It's also useful to confirm whether your property has a single-phase or three-phase electrical supply, as this affects system design.

3. Decide What's Most Important

Think about your priorities.

For example:

• Maximising your solar self-consumption.

• Reducing electricity bills.

• Having backup power during outages.

• Preparing for future energy needs.

Your goals will determine the battery capacity, inverter type, and overall system design.

4. Arrange a Professional Site Survey

A reputable installer should carry out a detailed survey that includes:

• Inspection of your solar PV system.

• Inverter assessment.

• Consumer unit inspection.

• Cable route planning.

• Suitable locations for the battery and inverter.

You should also receive a proposal outlining:

• Estimated increase in self-consumption.

• Recommended battery capacity (kWh).

• Product warranties.

• Expected return on investment based on energy savings.

5. Ask the Right Questions

Before choosing an installer, ask:

• Are you NAPIT Approved and TrustMark Endorsed?

• What is the battery's usable capacity?

• What warranty is included?

• How many charging cycles is the battery designed for?

• Can the system provide backup power during an outage?

• Which household circuits will remain operational?

• How will the battery integrate with my existing solar inverter and EV charger?

• What monitoring and aftercare do you provide?

6. Understand Planning and Regulations

Most domestic battery storage systems do not require planning permission.

However, additional considerations may apply if your property is:

• Listed.

• Located within a conservation area.

• Installing equipment in an unusual location.

A professional site survey will identify any local planning or building regulation requirements.

7. Consider Ongoing Monitoring and Maintenance

Battery systems require very little physical maintenance but should be monitored to ensure they continue operating efficiently.

Ask whether your installer provides:

• Remote system monitoring.

• Firmware updates.

• Ongoing technical support.

• Warranty assistance if required.
