How much electricity solar panels make in Oxford

A south-facing 1kWp system at 35 degrees in central Oxford generates about 1,017 kWh a year, according to the EU's PVGIS model. That ranks 16 of the 31 areas we cover, which run from 850 kWh in Glasgow to 1,177 kWh in Sussex. East and west roofs still work, at roughly a fifth less.

Roof direction (35° pitch)	Per kWp a year	June	December
South-facing	1,017 kWh	121 kWh	36 kWh
East-facing	811 kWh	116 kWh	15 kWh
West-facing	794 kWh	113 kWh	15 kWh

PVGIS is a modelled figure for an unshaded roof with 14% system losses, and it runs higher than the MCS method installers must use for your written estimate, which gives roughly 800 to 950 kWh per kWp for a well-oriented UK roof. Use PVGIS to compare places and the installer's MCS estimate to plan your budget. Our guides to which direction panels should face and how much electricity solar panels produce go further.

What that electricity is worth in Oxford

Every unit you use yourself saves 26.47p, the Ofgem price cap rate for direct debit customers in the Southern England region from 1 October to 31 December 2026. The Great Britain average is 26.32p. Every unit you export earns whatever your Smart Export Guarantee tariff pays, which the Energy Saving Trust puts at around 12p typically.

Take the Energy Saving Trust's typical 4.5kWp home system. On the PVGIS figure for Oxford it would generate about 4,576 kWh a year. If you used all of it, that would be worth about £1,211. If you exported all of it, about £549. Real homes sit between the two, and a battery or daytime use pushes you towards the higher figure. The Energy Saving Trust prices that typical system at around £7,600. See our solar panel cost guide and current export rates.

Oxford has less solar than the county around it

Oxford had 3,149 solar installations at the end of 2025 across 55,200 households, about 57 per 1,000 by our count from the government's local authority table, below the UK average of about 69 and the lowest rate of Oxfordshire's five districts. The rural districts all run well ahead: Vale of White Horse at about 102 per 1,000, West Oxfordshire about 101, Cherwell and South Oxfordshire about 89 each. Oxfordshire as a whole had 25,197 installations and 610 MW across 288,100 households, about 88 per 1,000, and it grew 19.2% in a year, which is faster than the national rate. The government warns that its 2025 figures were produced before the latest postcode lookup, so 31,900 installations across Great Britain are still unassigned and these counts will be revised upward.

That gap is not about sunshine. Oxford sits in the South East, which DESNZ's first regional breakdown put top of the UK with 22,628 installations in 2026 up to July and 305,101 in total, up 14% on the previous July. The city's own number is held back by what its roofs are and who owns them, which the next two sections cover.

Heritage controls: 18 conservation areas, two Article 4 directions and 1,500 listed buildings

Oxford City Council's own householder guidance says permitted development rights are reduced in its conservation areas, so planning permission will be needed to install solar panels there. The city has 18 conservation areas, running from the college core out to Headington Hill and the Wolvercote and Godstow meadows. In two of them, Jericho and Osney Town, the council has gone further and used Article 4 directions to remove permitted development rights for changes to roof materials, solar panels included. Those are terraced streets with good roof pitches, which is exactly where the controls bite hardest.

The same guidance sets out the planning balance bluntly: where a listed building or conservation area is involved, the public benefits of a domestic array are unlikely on their own to outweigh the great weight that must be given to heritage harm, and it advises against fixing panels to the elevation a building is most commonly seen from. Oxford has around 1,500 listed buildings and more than twice the national average share of grade I and II* listings, and a listing covers the whole building, anything fixed to it and most structures in its curtilage. In practice that pushes Oxford installs onto rear and non-prominent slopes, which can mean a smaller or east-west array than a first quote assumes. Our guides to solar panels in a conservation area and solar panels on a listed building cover the English rules, and permitted development covers what applies outside the designated areas: rooftop solar on a house is usually permitted development, and a flat roof on article 2(3) land needs prior approval.

Only 45% of Oxford households own their home

Census 2021 found 45.3% of Oxford households own their home, against 61.3% across England, with 32.2% renting privately against 20.5% nationally. Roughly one household in two here cannot authorise a solar install on its own roof without asking a landlord or freeholder. That is a structural reason for the installation count, not a reflection of appetite.

The housing stock pulls the same way. Just 9.5% of Oxford households are in a detached home, against 22.9% for England; 31.7% are semi-detached, 27.8% terraced, 24.1% in purpose-built flats and a further 4.9% in converted or shared houses. Just under a third of Oxford homes are a flat of some kind, where the roof is rarely yours alone. Our guide to solar panels for flats covers the freeholder and lease questions, and how many panels you need helps if your usable roof is a single rear slope.

Grants: the Oxfordshire pot is shut

Warm Homes: Local Grant in Oxford funds solar photovoltaics and solar hot water, but Oxfordshire County Council, which delivers it, says it is no longer accepting new applications or expressions of interest because of high demand. The scheme it runs under describes itself as oversubscribed and closed to applications while it waits on a government decision about more funding this year. Where it is open, eligibility is an EPC of D to G plus either a household income of £36,000 or less before housing costs, or a listed means-tested benefit. The county council now points residents to the Better Housing Better Health service instead.

One part is worth knowing if you let property in Oxford: the grant is open to privately rented homes including HMOs, which matters in a city where a third of households rent privately. In a shared-cooking-facilities HMO, one tenant on a qualifying benefit makes the whole household eligible; where there are individual cooking facilities, eligibility is based on average household income across the residents. Oxford City Council itself runs no solar grant for private owners. Its strategy frames its role as promoting other people's grants and using planning and licensing powers, with a zero carbon council target for 2030 and a net zero city target for 2040, and its own retrofit funding of up to £2.6 million from the Social Housing Decarbonisation Fund goes to council tenants' homes. Our guide to solar panel grants in the UK has the national schemes.

Your network operator in Oxford

Oxford's network is run by Scottish and Southern Electricity Networks, which its own postcode look-up confirms for central Oxford. For a home system of 3.68kW or less per phase it uses the G98 fit-and-notify route: the system goes in first, then a G98 Form B must reach SSEN within 28 days of commissioning, by email.

There is one SSEN rule that catches Oxford streets in particular. SSEN wants prior approval rather than notification afterwards if another property in the same postcode district has had generation installed in the previous 28 days by the same installer. On a Jericho or East Oxford terrace where several neighbours book the same firm, that turns a fit-and-notify job into an approval job, so ask your installer how they are handling it before you agree dates. See our G98 and G99 guide. For a comparison, solar panels in Cambridge is the other historic university city we cover, and solar panels in Hampshire is also on the SSEN network.

Solar panels in Oxford: frequently asked questions

Are solar panels worth it in Oxford?

On the numbers, yes. A south-facing roof in central Oxford generates about 1,017 kWh per kWp a year on the PVGIS model, a typical 4.5kWp system would make about 4,576 kWh, and every unit you use saves 26.47p at the Southern England price cap rate for October to December 2026. The harder questions in Oxford are whether your roof is in a conservation area and whether you own it.

Why does Oxford have fewer solar panels than the rest of Oxfordshire?

Two reasons rather than sunshine. Oxford has 18 conservation areas, two Article 4 directions that remove permitted development rights for solar in Jericho and Osney Town, and around 1,500 listed buildings. And only 45.3% of Oxford households own their home, against 61.3% across England, so about half the city needs a landlord or freeholder to agree. Oxford runs at about 57 installations per 1,000 households against about 88 across Oxfordshire.

Do I need planning permission for solar panels in Oxford?

Inside a conservation area, yes. Oxford City Council says permitted development rights are reduced there, so permission will be needed, and in Jericho and Osney Town Article 4 directions remove the right for changes to roof materials including solar panels. A listed building needs listed building consent. Outside the designated areas, rooftop solar on a house is usually permitted development.

Is there a solar grant in Oxford?

Not open at the moment. Warm Homes: Local Grant does fund solar photovoltaics and solar hot water in Oxford, but Oxfordshire County Council has stopped accepting applications and expressions of interest because of high demand, and the scheme delivering it says it is oversubscribed while it waits on a government funding decision. Oxford City Council runs no solar grant of its own for private owners.

Who is the network operator for solar in Oxford?

Scottish and Southern Electricity Networks. A home system of 3.68kW or less per phase uses the G98 fit-and-notify route, with a G98 Form B due to SSEN within 28 days of commissioning. SSEN can require prior approval instead if the same installer has fitted generation in your postcode district in the previous 28 days.
