How much electricity do solar panels generate in Newcastle upon Tyne?

About 912 kWh a year for each kW of panels, for a roof-mounted, south-facing array at a 30° pitch with 14% system losses (PVGIS). A 3.0 kW system would generate about 2,700 kWh in its first year. Shade, a different roof angle or an east or west-facing roof will change this.

How long do solar panels take to pay back in Newcastle upon Tyne?

About 7.1 years for a 3.0 kW system costing £5,269 (the government’s median price for 0–4 kW systems), in a home using 2,700 kWh a year at Newcastle upon Tyne’s unit rate of 25.46p. It saves about £687 in the first year. That assumes the home uses all the electricity the panels generate, prices rise 3% a year and output falls 0.5% a year; exported electricity is counted at zero. At the Great Britain average unit rate of 26.32p, payback would be 6.9 years.

What is the electricity unit rate in Newcastle upon Tyne?

Under the Ofgem price cap for October to December 2026, single-rate electricity paid by Direct Debit costs up to 25.46p per kWh in the North Eastern England region, against a Great Britain average of 26.32p. The cap is the maximum for a standard variable tariff, so your own unit rate may be lower or higher on a fixed deal: use the rate on your bill in the calculator if you can.

How does Newcastle upon Tyne compare with nearby towns and cities?

Of the 5 nearest towns and cities we cover, Sheffield (113 miles away) gets the most sun at 911 kWh per kW, and Manchester (108 miles away) the least at 855 kWh. Newcastle upon Tyne gets 912 kWh, more than any of them. Within the North Eastern England price cap region, it ranks 6th of the 8 towns and cities we cover.

Where do these figures come from?

Solar generation is from the European Commission’s PVGIS 5.3 tool for Newcastle upon Tyne’s ONS centre point, checked on 2026-11-11. The unit rate is from Ofgem’s price cap tables, the installed price from the Department for Energy Security and Net Zero’s solar PV cost data, and typical use from Ofgem. Each figure is listed with its source link at the bottom of this page.

Solar panels in Newcastle upon Tyne: generation, savings and payback

Solar panels in Newcastle upon Tyne generate about 912 kWh a year for each kW installed, 5% less than the average of the 100 towns and cities in our data (960 kWh). Among the 8 places we cover in Ofgem’s North Eastern England region, it ranks 6th of 8 for solar output, against an average there of 917 kWh.

Newcastle upon Tyne is in Ofgem’s North Eastern England price cap region, where the unit rate for single-rate electricity paid by Direct Debit is 25.46p per kWh for October to December 2026: 0.86p below the Great Britain average of 26.32p.

For a home in Newcastle upon Tyne using Ofgem’s typical 2,700 kWh a year, a 3.0 kW system would cover a year’s use. At the government’s median installed price for 0–4 kW systems it would cost about £5,269, save about £687 in its first year and pay for itself in about 7.1 years. With the average sunshine of the 100 towns and cities in our data (960 kWh per kW), the same home would need a 2.8 kW system and pay back in 6.8 years, so Newcastle upon Tyne’s sunshine adds about 0.3 years to payback.

A typical home in Newcastle upon Tyne

System size: 3.0 kW; Sized to cover 2,700 kWh a year
First-year generation: 2,700 kWh
First-year savings: £687; At 25.46p per kWh
Savings over 25 years: £23,435; Prices rising 3% a year
Installed cost: £5,269; Government median for 0–4 kW systems
Payback: 7.1 years

Assumes all the electricity the panels generate is used at home, up to the home’s yearly use, and that panel output falls 0.5% a year. Power sent to the grid is counted at zero.
