Store surplus solar energy or off-peak power with our high-performance battery storage systems, designed to cut costs and increase self-sufficiency.
At A Greener Alternative, we help homeowners and businesses across Sussex, Surrey, Hampshire and Kent get the most from renewable energy with expertly designed and installed battery storage systems.
Battery storage works perfectly alongside a solar PV system, capturing surplus electricity your panels generate during the day so you can use it later in the evening or on cloudy days instead of drawing expensive power from the grid. This means lower energy bills, greater independence, and a smaller carbon footprint.
Even if you don’t yet have solar PV, battery storage can still unlock savings. By charging your batteries using cheaper off-peak electricity tariffs, you can power your home when rates are highest, reducing costs and avoiding price spikes.
At A Greener Alternative, we don’t believe in one-size-fits-all solutions. Every battery installation we deliver is tailored to your property, lifestyle and energy needs, whether you’re adding storage to an existing solar PV system or starting fresh. We focus on reliable, high-performance components chosen for longevity and backed by expert installation from our own directly employed electricians.
By combining battery storage with solar PV, you can make the most of renewable energy you produce yourself, reduce your reliance on the grid, and protect your property against rising electricity costs.
If you’re based in Sussex, Surrey, Hampshire or Kent and want to take control of your energy use, talk to A Greener Alternative today about a smarter, greener way to power your home.

Where can my home battery be installed?
All our batteries are fully IP rated for both internal and external installations. Your installation engineer will discuss your preferred location with you ahead of the works. If you have any specific requests, please contact the office ahead of ordering. Please note that new guidelines recommend not installing batteries in main loft spaces.
Do I need planning permission to install a home battery?
In most cases, no planning permission is required for domestic battery storage installations. However, if you live in a listed building or conservation area, additional permissions may be needed. We’ll advise you on any requirements during your free survey.
How long does the installation take?
Most battery storage installations can be completed in a single day. Complex installations or those requiring additional electrical work may take up to two days. We’ll provide you with an accurate timeline during your survey.
Do I need a smart tariff, and if so, which one?
To maximise savings, we recommend a time-of-use tariff such as Octopus Go, Agile, or Economy 7. These tariffs offer cheaper electricity during off-peak hours, which your battery can store for use during expensive peak times. We’ll help you choose the best tariff for your usage patterns.
How long is the warranty?
Most battery systems come with a 10-year warranty and are expected to last 20 to 25 years. We provide comprehensive warranty coverage and ongoing support throughout the life of your system.
Do I need existing solar panels for battery storage?
No! Battery storage works excellently as a standalone system. You can charge from cheap off-peak grid electricity and use it during expensive peak hours. However, combining with solar panels maximizes your savings and energy independence.
What size battery do I need?
Battery size depends on your energy usage patterns, existing solar generation (if any), and budget. During our free survey, we’ll analyze your energy bills and usage to recommend the optimal battery size for your needs.
How much can I save with battery storage?
Savings vary based on your energy usage, tariff, and battery size. Many customers see 60-80% reduction in electricity bills when combining battery storage with solar panels, or 30-50% savings with standalone battery systems using time-of-use tariffs.
