Solar Battery Storage Quotes Across Hampshire
Solar batteries store surplus daytime generation so the house can run on it after dark. Through one enquiry, Hampshire households can reach up to four local solar and storage specialists for free, no-obligation quotes.
Storage works as part of a brand-new installation or as a retrofit to older panels, and many Hampshire owners also charge them overnight on a cheaper tariff.
Who Benefits Most from Battery Storage?
Without storage, a typical household uses around a third to a half of its own solar generation. Exported units earn far less than what you pay for electricity from the grid. A battery closes that gap, especially where most electricity is used in the evening.
- Homes empty during working hours
- Anyone able to charge cheaply overnight
- Electric car or heat pump owners
- Systems that regularly export most of their output
Choosing the Right Battery Set-Up
An AC-coupled battery sits alongside your current solar inverter with its own charger. It is often the simplest retrofit. A hybrid set-up swaps the old inverter for one that manages panels and storage together, which is efficient and makes sense if the old inverter is ageing.
Compare usable kWh rather than headline capacity: most homes choose between about 5kWh and 13.5kWh. The battery's power rating decides whether it can cover the oven, kettle and shower at the same time.
How Much Does a Home Battery Cost in Hampshire?
| Battery set-up | Typical price range |
|---|---|
| Around 5kWh, AC-coupled retrofit | £3,000 – £4,500 |
| Around 8–10kWh | £4,500 – £6,500 |
| 13kWh+ or with a hybrid inverter swap | £6,500 – £8,500+ |
| Backup (emergency power) function | Often extra – check the quote |
Batteries installed in homes currently qualify for 0% VAT, including retrofits. Your fixed price will follow a site visit.
Planning and Safety for Home Batteries in Hampshire
Planning consent is not usually required for a battery installed inside a home or garage, although listed buildings may need consent for any external works. For local planning guidance, contact Hampshire County Council.
Electrical work must meet the rules in the relevant UK nation and the wiring regulations, and use the IET energy storage guidance when choosing a safe battery location. Your network operator must also be notified or asked for approval, with the process depending on total inverter output.
Choosing a Battery Installer in Hampshire
- Do they hold MCS certification covering batteries?
- Why is this capacity right for your usage?
- Will the battery work during a power cut?
- Will they set up charging for your tariff?
- How much capacity is guaranteed at the end of the warranty?
Checking the Proposed Work
A battery survey should compare your evening use with the usable battery capacity, then check the existing inverter, meter position and a suitable indoor mounting location. Ask whether backup circuits are included: ordinary battery storage does not automatically keep sockets working during a power cut.
Written details make different proposals easier to compare before choosing a contractor.
Frequently Asked Questions
The answers below cover points homeowners often raise before requesting a quote.
Can a battery be added to solar panels fitted years ago?
Yes. An AC-coupled battery can usually work alongside an existing solar inverter, or the old inverter can be replaced with a hybrid model that controls both the panels and the battery.
How long does a solar battery last?
Most home batteries come with a warranty of around 10 years, usually guaranteeing a minimum share of the original capacity. Many continue working beyond that with gradually reduced capacity.
Where can a home battery be installed?
Common locations include a garage, utility room or an external wall. Some manufacturers restrict loft or living-space installation, and the installer will check temperature, ventilation and fire-safety requirements.
