Solar panels in Newcastle upon Tyne: winter, grid and planning

Solar output in Newcastle upon Tyne

Newcastle is further north than most cities in this guide, so it is fair to ask whether panels pay. PVGIS, the European Commission’s solar tool, models about 950 kWh a year for each kWp. That is for a south-facing roof at 35 degrees. The PVGIS run for Newcastle lists the inputs.

Because the city is further north, the best fixed tilt is steeper, at about 43 degrees. That models at 956 kWh per kWp. The gain is only six units, so an ordinary roof pitch loses very little.

A worked example shows the scale. Specifically, a 4 kWp system would make about 4 x 950, or 3,800 kWh a year. This is a modelled estimate. Real output depends on shade, direction and the weather in a given year.

That annual figure hides a seasonal swing. Days are short in winter, and the sun sits low. As a result, most of the year’s power arrives in spring, summer and early autumn.

What winter means for you

Our post on solar panels in winter looks at seasonal output, snow and short days. It is worth reading if you worry about the dark months. Panels still work in winter, but they make much less.

This changes how you judge a system. Judge it on the whole year, not on one cold week. A battery can help shift some summer surplus into the evening, although it cannot create power that was never made.

Connecting to the grid

Northern Powergrid runs the North East network that serves Newcastle. It must be told about any new generator. Because systems differ, the route depends on the size of your system.

The MCS solar standard sets the split. Up to 16 A per phase follows G98, and above that follows G99. All generators count together, so a battery adds to the total.

MCS also says the installer makes the notification. Still, ask when it was sent and keep the confirmation. You may need it for your export tariff.

Planning in Newcastle

Newcastle City Council is the planning authority. Many houses can fit panels without a full application. However, England’s permitted development rules for solar changed on 27 August 2026.

Houses and blocks of flats now follow different rules, as the Planning Portal sets out. Eligible projects can still use the older rules until 26 August 2027. Because the details are fiddly, confirm them with the council.

However, conservation areas and listed buildings carry extra limits. Flats also follow their own route. Ask the council in writing before you pay a deposit.

Checking an installer

Start with MCS, because it shows a firm meets a recognised standard. Our guide to MCS-certified solar installers explains what the mark covers and how to check a firm. The MCS installer search is public and free.

MCS matters for export payments too. GOV.UK says both your installation and your installer need certification before you can claim a Smart Export Guarantee tariff. The scheme checks this. Without that, spare power earns nothing.

Next, check consumer protection. RECC members must insure deposits, stage payments and workmanship warranties. Therefore, a firm that stops trading should not take your money with it.

Tax and grants

HMRC currently zero-rates solar panels and batteries. That relief runs to 31 March 2027, and the rate then returns to 5%. So the date can affect when you choose to buy.

In England, the Warm Homes: Local Grant lists solar PV among its measures. It is for low-income, privately owned homes with an EPC rating of D to G. Councils deliver it, so ask yours whether it applies.

Comparing quotes and costs

Collect three written quotes, because prices and scope vary, and compare them line by line. Look at panel count, inverter, warranty and who handles the grid paperwork. Our page on solar panel installation lists what a full job includes.

For prices, DESNZ reports a median of about £1,780 per kW of declared net capacity for 0-4 kW installs in 2025/26. That covers Great Britain and leaves out batteries. Our solar panel costs guide explains how to use it.

York is the nearest English city in our set with the same network operator. See our page on solar installers serving York for a slightly higher modelled yield.

When you are ready, you can request quotes from vetted MCS installers. Nobody contacts you until you send the form.
