Battery Storage Systems
Store your solar energy and use it day and night. Battery storage installation for Sunderland homes and businesses.
A solar battery lets you store the electricity your panels generate during the day so you can use it in the evening when demand is highest. For Sunderland households facing high standing charges and unit rates, battery storage dramatically increases the value of every unit your panels produce.
Key benefits
- Use your own solar power after dark instead of buying from the grid
- Charge cheaply overnight on a time-of-use tariff
- Keep essential circuits running during a power cut (with backup-ready units)
- Scalable capacity from 5kWh to 20kWh and beyond
- Works with new and existing solar installations
How battery storage transforms your solar savings
Without a battery, any solar electricity you do not use the instant it is generated is exported to the grid for a few pence per unit, only for you to buy it back later at a far higher rate. A battery closes that gap. It captures your midday surplus and releases it through the evening peak, so a far greater share of your generation directly offsets expensive grid electricity. For many Sunderland homes this lifts self-consumption from around a third to well over three-quarters of everything the panels produce.
Charge cheaply, even in winter
Battery storage is not only for sunny months. Paired with a time-of-use electricity tariff, your battery can charge from the grid during the cheapest overnight hours and power your home through the costly daytime and evening periods. This means the system keeps saving you money throughout the darker Sunderland winter, and is particularly valuable for households that have moved to an electric vehicle or a heat pump.
Choosing the right size and type
Battery capacity is measured in kilowatt-hours (kWh). We size your battery around your evening consumption and the output of your solar array so it fills up on a good day and empties over the evening without being wastefully large. Most homes are well served by 5kWh to 10kWh; larger households and those with EVs often choose more. We fit reputable lithium-iron-phosphate (LFP) batteries, which are safe, long-lasting and come with substantial warranties.
Backup power and peace of mind
Certain battery systems can be configured to provide backup power, keeping your lights, fridge, broadband and other essential circuits running during a grid outage. If resilience matters to you, we will specify a backup-capable inverter and battery and explain exactly which circuits can be supported. Whether your priority is maximum savings, energy independence or both, we will design storage around your goals.
Why choose a local Sunderland team
As a genuinely local company we cover the whole of Sunderland and Wearside — from Roker, Seaburn and Fulwell on the coast to Washington, Houghton-le-Spring and the former pit villages inland. Because our engineers are directly employed rather than subcontracted, the same trusted team that quotes your battery storage systems carries it out and looks after you afterwards. That local presence means faster appointments, quicker aftercare and advice grounded in real experience of North East homes, businesses and weather.
How the process works
Everything starts with a free, no-obligation survey at a time that suits you. We assess your property, talk through your goals and budget, and then provide a clear, itemised quotation with no hidden extras and no pressure. Once you are happy to proceed we handle every detail — design, any notifications to your network operator, the installation itself and full certification — before walking you through your new system and handing over complete documentation. Our relationship does not end there: we remain on hand for servicing, monitoring and support for years to come.
Accreditations, warranties and finance
We are fully MCS and RECC certified, so our work qualifies for the Smart Export Guarantee and any grant support available, and is carried out to recognised industry standards. We fit only quality, well-supported equipment backed by substantial manufacturer warranties and our own workmanship guarantee, and we can spread the cost through flexible finance options including interest-free packages on selected work. Whatever your circumstances, we will set out the figures transparently so you can make a confident, informed decision.
