Battery Storage Systems for Homes

Battery storage systems for homes have quickly evolved from a costly luxury to a smart, practical investment. Once seen as too expensive and underdeveloped, battery technology has advanced rapidly—thanks in large part to innovation and mass production in the electric vehicle industry.

Today, installing a home battery system, especially alongside a Solar PV system, offers a powerful way to maximise your energy savings. By storing excess solar energy for use when the sun isn’t shining, battery storage can increase savings from 25–35% to as much as 65–85%. In many cases, our customers become nearly self-sufficient, cutting energy bills and reducing dependence on the grid.

If you’re considering Solar PV, adding battery storage is a smart step toward energy independence.

How it works

Our expertise in Solar PV installations, combined with our MCS accreditation, has positioned us at the forefront of the growing domestic battery storage market. We’ve refined our installation process to design and deliver battery storage systems that work efficiently for each customer, providing greater energy flexibility and significantly lower electricity bills with realistic payback periods.

Whether you’re installing a brand-new Solar PV system or upgrading an existing one, we can integrate battery storage to help you make the most of your solar energy. Even if you already have solar panels, you can still benefit from adding a battery system to store excess energy and reduce your reliance on the grid.

Technology

Battery technology has been around for decades, with the first rechargeable lithium-ion batteries introduced in the 1970s. However, large-scale production and higher-capacity batteries only became commercially viable for the domestic market around 2021—especially as energy prices began to rise sharply. Today, home battery storage systems offer an efficient way to store DC electricity, just like the energy produced by solar panels. An inverter then converts this stored DC power into AC electricity for use in your home. Thanks to recent advances in inverter technology, energy losses during the DC-to-AC conversion process are now minimal. Looking ahead, continued innovation promises even better battery technology, with higher storage capacities, improved efficiency, and new battery types on the horizon. As a result, battery storage is rapidly becoming a smart, future-proof investment for homeowners.
The lifespan of lithium-ion (Li-ion) batteries depends on usage and is typically measured in charge and discharge cycles. On average, a well-maintained battery storage system lasts around 10 years with only about 20% degradation in capacity. For example, a 10kWh battery may store the full 10kWh when new but around 8kWh after a decade of use. This natural degradation happens as the battery charges and discharges—similar to how smartphone or laptop batteries lose capacity over time. However, you can extend your battery’s life by managing how you use it. For instance, keeping the charge level between 20% and 80% and avoiding full discharges can significantly improve longevity. Even better, lithium-ion batteries are recyclable at the end of their life. This means when it’s time to replace your battery, the old one can be fully recycled—making battery storage not only energy-efficient but also environmentally friendly.

Our process

Consult

From your first enquiry, we arrange a consultation or site survey. This helps us understand what you want from a solar PV system. Next, we create a tailored proposal. This includes a full breakdown of system performance, expected carbon savings, and estimated energy bill reductions. We design your solar system to meet your needs and maximise your savings.

Applications 

If you decide to go ahead, we handle all the admin for you. We submit applications to the DNO and complete any final design work. Once that’s done, we arrange scaffolding so installation can begin.

Install

Most solar PV installations take 2 to 3 days to complete. This depends on the system size and whether you include battery storage. We minimise disruption and keep your power on for as long as possible. Power is only switched off briefly when we connect the system to the grid. We typically install your system within 4 to 6 weeks of placing the order.

Handover

Once installation is complete, we test and commission the system. Then, we remove the scaffolding. Next, we provide a handover pack with system details and your MCS certificate. We also notify the DNO that the system is commissioned. Our after-sales support includes a remote monitoring package. This lets us track system performance and receive alerts for any faults or errors.

Battery storage myths

Battery storage is not efficient.

Battery storage systems have become more efficient in recent years. Lithium-ion batteries, widely used in energy storage, offer high round-trip efficiency. They typically achieve 85% to 95% efficiency. This means they store and release energy with minimal losses.

Battery storage is not cost-effective.

Battery storage systems require a significant upfront investment. However, costs have steadily declined. Advances in battery technology, economies of scale, and improved manufacturing efficiency drive this drop. As demand for batteries grows, prices will continue to fall. This trend makes battery storage more cost-effective over time.

Battery storage is not reliable.

Battery storage systems provide reliable backup power and store excess energy from renewable sources. They integrate with smart control systems to maintain a steady and stable power supply. Additionally, batteries can connect to increase storage capacity, boosting reliability even more.

Battery storage is bad for the environment.

Battery manufacturing and disposal have environmental impacts. However, modern lithium-ion batteries are more eco-friendly than older types. Plus, battery storage boosts renewable energy use. This reduces reliance on fossil fuels and cuts greenhouse gas emissions, making the overall impact positive.

Battery storage is only suitable for short-term applications.

Battery storage systems provide both short-term and long-term energy solutions. Short-term uses include load shifting, peak shaving, and grid stabilization. Long-term uses involve storing renewable energy for times of low generation. With proper design and sizing, battery storage meets a wide range of energy needs effectively.
