Solar panels generate the most power in the middle of the day — often while you're out at work. A battery stores that surplus so you can use it later, instead of selling it back to the grid at export rates and buying it back at a higher price in the evening.

Solar Panels and Batteries Work Even Better Together
Without a battery, any electricity your panels generate that you're not using right away gets sent back to the grid through the Smart Export Guarantee. That's still worthwhile — but a battery lets you use more of your own power first, cutting your reliance on grid electricity further and reducing your bills more than solar panels alone.
You don't need new solar panels to add a battery. We regularly retrofit battery storage onto existing solar PV systems across Kent, as well as installing solar and battery together as a single system.
Benefits of Battery Storage in Kent
Here's what a well-sized battery adds on top of solar panels alone:
Use More of Your Own Power
Store daytime solar generation and use it in the evening instead of buying electricity back from the grid at a higher rate than you were paid to export it.
0% VAT
Battery storage installed alongside solar, or added on its own, currently qualifies for 0% VAT — the same relief as the solar panels themselves.
Smarter SEG Earnings
Use your own power first, then export genuine surplus — rather than exporting everything you generate the moment it's produced.
Works With Existing Solar
Already have solar panels? Most systems can have battery storage retrofitted without replacing your existing panels or inverter setup.
Pairs With EV Charging
Charge your electric vehicle using stored solar power instead of grid electricity.
Lower Carbon Footprint
Using more of the clean electricity you generate yourself, rather than drawing from the grid, further reduces your home's carbon footprint.

Frequently Asked Questions About Battery Storage
Everything you need to know about adding solar battery storage in Kent with Transcrew.
A battery stores surplus electricity your solar panels generate during the day. Instead of that surplus being exported to the grid straight away, you can draw on it later — in the evening, overnight, or on a cloudy day — reducing how much electricity you need to buy from your supplier.
In most cases, yes. We regularly retrofit battery storage onto existing solar PV systems, compatibility depending on your current inverter. We'll confirm this during your free survey.
Yes. Battery storage currently qualifies for 0% VAT, whether installed alongside new solar panels or added to an existing system, until the relief's scheduled end in 2027.
Home battery storage is generally considered permitted development and does not require planning permission in most cases. Exceptions can apply to listed buildings and some conservation areas — we'll advise you during your free survey.
Some battery and inverter combinations support backup power during a grid outage, others don't by default. If backup power matters to you, let us know during your survey so we can recommend a system that supports it.
It depends on your household's energy usage and how much your solar panels generate. During your free survey, we'll size a battery to match your actual usage pattern rather than over- or under-specifying it.
You'll typically export less electricity overall, since you're using more of it yourself first — but each unit you do export is still paid under the Smart Export Guarantee. Most households find the saving from using their own power outweighs the reduction in export income.
