New solar

New solar panels for Cirencester homes

From terraces near the town centre to newer homes on the edge of town and villages like South Cerney and Siddington, most Cirencester roofs can take a worthwhile system.

  • Designed around your roof and your usage

    We size the system to your roof and how you use electricity, not to a standard package.

  • A battery now or later

    Fit one with the panels, or choose an inverter that makes adding one later straightforward.

  • 0% VAT on home solar

    Scheduled until 31 March 2027, on panels and batteries fitted to homes.

Existing systems

Already have solar panels in Cirencester?

Lots of Cirencester homes have had panels for ten years or more. Here’s how we can help you get more from yours.

Inverter replacement

The inverter turns your panels’ power into electricity your home can use. It doesn’t last as long as the panels, so on an older system it’s often the first part to fail.

Adding a battery

Store the surplus you’d otherwise export and use it in the evening. Most existing systems can take one, including Feed-in Tariff systems, with the right wiring.

A system check

If your generation has dropped, a check can find out why: a faulty inverter, a tripped switch, or a tree that’s grown and now shades the roof.

More panels

Got roof space left? A second set of panels can often be added. On a Feed-in Tariff system it needs to be wired so it doesn’t affect your FIT payments.

Feed-in Tariff homes

On the Feed-in Tariff? Read this before adding a battery

If your panels went up before the Feed-in Tariff closed in 2019, you may still be paid for every unit they generate. A battery won’t stop that, as long as it’s fitted the right way.

FIT payments are based on your generation meter, which should only count what your panels produce. The battery needs to sit where it can’t change that reading, and your FIT supplier needs to know about it.

Adding a battery to a FIT system

  • Tell your FIT supplier first: Ofgem says every system with a battery must be declared.
  • Send them a diagram showing where the battery sits. We can draw this for you.
  • An AC-coupled battery, fitted after the generation meter, is usually the simplest option.
  • The battery’s position can affect deemed export payments, so it’s worth getting the design right.

Planning

Solar panels in Cirencester’s conservation areas

Cirencester has four conservation areas. Rooftop solar is usually still permitted development in them, but panels can’t go on a wall or roof enclosure facing a road, and a flat-roof system needs prior approval. Listed buildings need consent first.

Cirencester FAQs

Solar panels in Cirencester: questions answered

About new systems and existing ones, including homes on the Feed-in Tariff.

Problem with an existing system?Call 01452 471031 and tell us what you’re seeing.

How do I know if my solar inverter has stopped working?

The usual signs are a blank screen or a warning light on the inverter, an error code, or your app or generation meter showing nothing on a bright day. First check that the isolator switches next to the inverter and the solar breaker in your consumer unit are on. If they are and it still isn’t generating, the inverter is the likely culprit. Don’t open it: it carries high voltage from the panels.

I’m on the Feed-in Tariff. Can I still add a battery?

Usually, yes. Ofgem requires you to declare a battery to your FIT supplier, and they’ll want a diagram showing where it sits in your system. An AC-coupled battery, fitted after your generation meter, is usually the simplest way to keep your FIT payments safe. Where the battery sits can affect deemed export payments, so it’s worth getting the design right first. See Good Energy’s guide for how one FIT supplier handles it.

Can I add more panels to my existing solar system?

Often, if you have roof space and your electrics can take it. Extra panels usually need their own inverter, or a bigger replacement one. If your current system gets Feed-in Tariff payments, the new panels must be wired so they don’t change what your FIT generation meter records, so talk to your FIT supplier before you start.

Do Cirencester’s conservation areas affect solar panels?

Usually not. Rooftop solar is permitted development within the size limits. Cirencester has four conservation areas: Town Centre, The Park, Gloucester Street and River Walk and South. In those, panels can’t go on a wall or roof enclosure facing a road, and a flat-roof system needs prior approval. Listed buildings need consent. You can check your address on Cotswold District Council’s conservation area maps.

Is it worth replacing old solar panels?

Usually not just because they’re old. Panels lose a little output each year but keep working for decades, so on most older systems it’s the inverter that needs replacing, not the panels. Replacing panels makes more sense if one is damaged, or if you want more output from the same roof: newer panels produce more from the same space.

What will a typical solar system generate in Cirencester?

A 4 kWp system facing south in Cirencester generates about 4,050 kWh a year: around 490 kWh in June and 130 kWh in December. Facing south-east or south-west it’s about 3,820 kWh, and facing east or west about 3,220 kWh.
