Future-proof your home with advanced solar battery storage. At Spectrum Energy Systems, we provide tailored solar battery solutions designed to maximise your energy efficiency, reduce reliance on the grid, and cut electricity bills. Whether you’re pairing storage with a new solar PV system or upgrading an existing setup, our expert team will help you find the right battery for your property and lifestyle.
What Is a Solar Battery and Why Does It Matter?
A solar battery stores the excess electricity generated by your solar panels during the day, allowing you to use it when the sun isn’t shining—such as at night, during overcast weather, or in the event of a power outage. This means greater energy independence and more consistent power for your home. Rather than sending unused energy back to the grid, you can store it and use it when needed.
- Reduce reliance on the grid
- Lower your electricity bills
- Power your home during outages
- Maximise your solar investment
Benefits of Home Solar Battery Storage

- Eco-Friendly Living – Reduce fossil fuel use and minimise your home’s carbon footprint by using clean, stored solar energy.
Choosing the Right Solar Battery for Your Home
The ideal solar battery system depends on several key factors:
- Battery Size & Capacity (kWh): How much energy do you need to store?
- Usage Patterns: When and how much energy you consume affects battery type and size.
- Backup Requirement: Do you want to stay powered during grid outages?
- Budget: We’ll match a system to suit your financial goals and return on investment expectations.
Our experienced surveyors will assess your home and energy habits to recommend a customised battery solution.
Types of Solar Batteries We Offer
Tesla Powerwall
A sleek, high-performance option that offers stand-alone capability and can be mounted outdoors. It charges from both solar and the grid—ideal for modern, energy-conscious homes.
Fox Hybrid Battery Systems
Fox batteries offer a reliable and flexible hybrid solution that can be charged via both solar energy and the grid. Perfect for residential properties and small businesses seeking robust, scalable storage.

Integrating Solar Panels with Battery Storage
When combined with solar panels, a battery storage system ensures that none of your solar energy goes to waste. Rather than sending excess power back to the grid, the energy is stored for use during evenings, cloudy days, or times of high demand. This means your home can rely more on self-generated power, improving energy independence and cost-efficiency.
- Key benefits include: Optimised self-consumption of your solar power
- Reduced reliance on utility companies and rising tariffs
- Greater control and predictability over your monthly energy bills
Real Homes, Real Results
From listed buildings to new-build homes, we’ve installed battery systems across a wide range of property types.
- David & Marisa’s Grade II-listed home in Nottingham: By combining solar panels, air source heating, and a lithium-ion battery, we helped them reduce their carbon footprint by 27 tonnes annually.
- Modern family home retrofit: We upgraded their underfloor heating system with an air source heat pump and expanded their solar battery storage to 7kWh—cutting 1.7 tonnes of CO₂ yearly.
Maintenance & Battery Replacement
To ensure your solar battery system continues to perform at its best, we recommend an annual service. Our expert maintenance team will thoroughly inspect your system for any signs of reduced performance, potential faults, or wear and tear that could impact efficiency. Regular servicing helps prevent unexpected issues, extends the lifespan of your battery, and maintains optimal energy storage and usage. By keeping your system in peak condition, you’ll continue to enjoy reliable, uninterrupted power and maximise the return on your solar investment year after year.
Funding & Incentives for Solar Batteries
Although there is currently no nationwide funding available for solar battery systems, domestic installations are VAT-free, which offers immediate cost savings. Additionally, some Local Authority schemes may provide grants or financial assistance to eligible homeowners. We recommend checking with your local council to see what support might be available in your area. For further guidance, visit our dedicated Solar Grants page for up-to-date information and eligibility details.

FAQs
Q1: Which is the best solar battery for home?
The best solar batteries for home depend on your energy needs and budget. Popular options include lithium-ion residential solar batteries because they last longer, charge quickly, and need less maintenance. When paired with a home solar battery, you can store extra solar energy for night use or during outages. Many homeowners also use a battery backup system to keep essential appliances running. Checking local solar battery incentives can also help reduce the cost.
Q2: How long will a 10kWh battery power a house?
A 10kWh home solar battery can usually power a house for 8–12 hours, depending on usage. For basic needs like lights, fridge, and Wi-Fi, it may last even longer. However, if you run large appliances like air conditioners or electric heating, the time will be shorter. Pairing residential solar batteries with solar panels ensures continuous charging during the day. With the right battery backup, you can enjoy reliable power during outages.
Q3: What type of battery is best for a home solar system?
Lithium-ion is often considered the best solar battery for home use because of its long lifespan and high efficiency. They are better than lead-acid residential solar batteries, which are cheaper but need more maintenance. A home solar battery with lithium technology works well with most solar systems and provides dependable backup. Before buying, check if there are any solar battery incentives in your area to lower costs.
Q4: How much is a 5kWh solar battery for a house?
The cost of a 5kWh home solar battery in the UK usually ranges from £3,000 to £6,000, depending on the brand and features. Installed systems with premium models can be higher, around £8,000 to £10,000. Many homeowners invest in residential solar batteries because they cut electricity bills and provide backup during power outages. Choosing from the best solar batteries for home ensures long-term savings and reliable energy storage.
