The short answer for Newcastle: a 4kW south-facing system in Newcastle generates about 3,790 kWh a year on the EU's PVGIS model — about 7% less than London. Installed prices for that size run roughly £6,600–£7,800 on the government's 2025/26 cost data, and at October–December 2026 North East electricity prices (25.46p/kWh) it is worth roughly £700 a year without a battery, or £800 if a battery lets you use most of it yourself.
Newcastle surprises people: its annual solar yield per kW is close to Sheffield's and Leeds's. What differs is the winter — short December days mean very little output — and the housing, where a third of homes are flats, including the city's distinctive Tyneside flats.
How much a solar panel system generates in Newcastle
The table uses the European Commission's PVGIS tool for Newcastle: crystalline panels at a 35° pitch, with PVGIS's standard 14% allowance for system losses and the local horizon. Your installer's MCS estimate will differ a little because MCS uses its own irradiance tables and your actual pitch and shading, but the gap between places and orientations is what matters here.
| Roof faces | Per kW | 3kW system | 4kW system | 6kW system |
|---|---|---|---|---|
| South | 948 kWh | 2,840 kWh | 3,790 kWh | 5,690 kWh |
| East | 738 kWh | 2,210 kWh | 2,950 kWh | 4,430 kWh |
| West | 730 kWh | 2,190 kWh | 2,920 kWh | 4,380 kWh |
Annual output, PVGIS 5.3 (SARAH3 satellite data, 2005–2023) for Newcastle, fetched 23 September 2026. Actual output varies year to year.
Of the 8 areas we cover, Newcastle ranks sixth for south-facing yield (Cornwall is highest at 1,066 kWh per kW, Manchester lowest at 886). The seasons matter as much as the location: in December a 4kW system here makes about 110 kWh for the whole month, against 454 kWh in June — which is why a battery is mostly a summer and shoulder-season tool, and why nobody should promise you winter bills near zero.
The trade-off in the North East is seasonal rather than annual. Long June days make up much of the difference with the south, but December output in Newcastle is among the lowest of the places we cover. If you are sizing a battery, size it for spring-to-autumn surpluses rather than expecting it to carry you through winter evenings.
What solar costs and saves in Newcastle
There is no separate "Newcastle price" for solar — installers price by system size, roof and access — so the fairest benchmark is the government's own cost series. Across domestic installations registered with MCS between April 2025 and March 2026, the average installed cost was £1,955 per kW for systems up to 4kW and £1,645 per kW for 4–10kW, VAT included and batteries excluded.
| System | Output in Newcastle | Typical installed price | Year-one value, no battery | Simple payback |
|---|---|---|---|---|
| 3kW | 2,840 kWh | £4,900–£5,900 | £500 | 10–12 years |
| 4kW | 3,790 kWh | £6,600–£7,800 | £700 | 10–12 years |
| 6kW | 5,690 kWh | £9,900–£11,700 | £1,000 | 10–12 years |
Price range: DESNZ Solar PV cost data (published 28 May 2026), each size priced between the 4–10kW average (£1,645/kW) and the up-to-4kW average (£1,955/kW); bigger systems tend towards the lower figure per kW. Value: south-facing PVGIS output, 40% used in the home at the North East price-cap unit rate of 25.46p/kWh (1 October to 31 December 2026), the rest exported at 12p/kWh (the 12p rate several large suppliers pay their own import customers in September 2026). Payback ignores panel degradation, future price changes and inverter replacement.
Two things move those numbers more than anything about Newcastle itself. First, how much you use yourself: every unit you use saves 25.46p, every unit you export earns only what your export tariff pays — 12p in this illustration. Our illustration assumes you use 40% without a battery; with a battery taking that to around 70%, the same 4kW system is worth about £800 a year — but the battery adds several thousand pounds, so price it as its own line and judge it on its own payback (battery storage guide). Second, the export tariff: rates are set by suppliers, not Ofgem, and range widely — see the solar payback guide for current examples.
VAT on solar panels and batteries installed in homes is 0% until 31 March 2027 (how the relief works), so a quote that adds 20% VAT to a domestic install is wrong.
Local group-buying: the North East Combined Authority's Switch Together solar group-buy for Newcastle and the wider region has a registration window of 3 August to 27 September 2026 (NECA). If you've registered, its price is a useful benchmark for any quote.
Newcastle homes and what they mean for your roof
Census 2021 counted 122,797 households in Newcastle upon Tyne: 34.6% semi-detached, 23.6% terraced, 9.5% detached and 32.3% flats or maisonettes, with 49.2% owner-occupied and 22.8% privately rented (England and Wales: 61.6% owned).
A third of Newcastle households live in flats, and many of those are Tyneside flats — terraced buildings split into an upstairs and a downstairs flat, each with its own front door. The roof usually belongs to, or is shared with, the upper flat, so a downstairs owner generally cannot install panels without the upstairs owner's agreement, and the title deeds decide who owns which part of the roof. If you own the upper flat, check your deeds and talk to your neighbour before you get quotes; installers will ask.
Semi-detached houses are the largest single group, and most are a straightforward fit for a 3–4kW system. Just under half of households own their home, so a large share of enquiries from renters need the landlord to commission the work.
Planning permission in Newcastle
For houses in England, roof-mounted solar is permitted development — no planning application — as long as the panels stand no more than 20cm proud of the roof slope and don't rise above the highest part of the roof. The main exceptions are listed buildings (which need listed building consent), panels mounted on a wall that faces a road in a conservation area, and properties where the council has removed permitted development rights with an Article 4 direction. Blocks of flats have their own, similar permitted development rules, but panels on a shared roof still need the freeholder's consent. The rules were last amended on 27 August 2026.
Newcastle City Council says there are 12 conservation areas in the city (council page) and confirms that houses have permitted development rights for "installing solar panels, heat pumps and wind turbines" (council guidance). Older Article 4 directions restrict roof alterations in Summerhill and Northumberland Gardens (Article 4 list) — check before fitting panels on a roof slope there. Tyneside flats are flats, not houses, so the rules for blocks of flats apply.
Connecting to the grid: Northern Powergrid (Northeast)
Newcastle's local network is run by Northern Powergrid, which covers the North East and Yorkshire licence areas. Your installer notifies or applies to Northern Powergrid for the connection; your electricity supplier is a separate company.
For a typical home system the installer handles this. A single-phase installation up to 3.68kW of inverter capacity (16 amps per phase) is connected under the G98 process and the network operator is notified within 28 days of commissioning. Anything larger — including a bigger system, or panels plus a battery whose combined inverter capacity passes that limit — goes through G99, which needs the network operator's approval before installation and can add weeks. Ask your installer which route your design needs and whether an export limit is being applied.

Questions from Newcastle homeowners
Is solar worth it that far north?
Over a whole year a south-facing roof in Newcastle produces about the same per kW as Sheffield or Leeds on PVGIS data. Winter output is low, so the savings come mostly from April to September. The payback table above uses Newcastle's own output and North East prices.
I own a Tyneside flat — can I get panels?
Possibly, if you own or have rights over the roof. Upper-flat owners are usually in the stronger position; lower-flat owners normally need the upper owner's agreement. Check your title deeds before paying for a survey.
Does the cold reduce output?
No — panels are slightly more efficient when cool. Low winter output in the North East is about day length and sun angle, not temperature.
Will Northern Powergrid need to approve my system?
Only for larger systems. Most single-phase home systems up to 3.68kW of inverter capacity are simply notified after installation; bigger ones, or panels plus a large battery, may need approval first. Your installer handles it.
