How much electricity do solar panels generate in Birmingham?

About 932 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 2.9 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 Birmingham?

About 6.9 years for a 2.9 kW system costing £5,157 (the government’s median price for 0–4 kW systems), in a home using 2,700 kWh a year at Birmingham’s unit rate of 25.60p. It saves about £691 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 6.8 years.

What is the electricity unit rate in Birmingham?

Under the Ofgem price cap for October to December 2026, single-rate electricity paid by Direct Debit costs up to 25.60p per kWh in the West Midlands 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 Birmingham compare with nearby towns and cities?

Of the 5 nearest towns and cities we cover, London (101 miles away) gets the most sun at 981 kWh per kW, and Edinburgh (245 miles away) the least at 884 kWh. Birmingham gets 932 kWh. Within the West Midlands price cap region, it ranks 8th of the 11 towns and cities we cover.

Where do these figures come from?

Solar generation is from the European Commission’s PVGIS 5.3 tool for Birmingham’s ONS centre point, checked on 2026-11-10. 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 Birmingham: generation, savings and payback

Solar panels in Birmingham generate about 932 kWh a year for each kW installed, 3% less than the average of the 100 towns and cities in our data (960 kWh). Among the 11 places we cover in Ofgem’s West Midlands region, it ranks 8th of 11 for solar output, against an average there of 938 kWh.

Birmingham is in Ofgem’s West Midlands price cap region, where the unit rate for single-rate electricity paid by Direct Debit is 25.60p per kWh for October to December 2026: 0.72p below the Great Britain average of 26.32p.

For a home in Birmingham using Ofgem’s typical 2,700 kWh a year, a 2.9 kW system would cover a year’s use. At the government’s median installed price for 0–4 kW systems it would cost about £5,157, save about £691 in its first year and pay for itself in about 6.9 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 6.7 years, so Birmingham’s sunshine adds about 0.2 years to payback.

A typical home in Birmingham

System size: 2.9 kW; Sized to cover 2,700 kWh a year
First-year generation: 2,700 kWh
First-year savings: £691; At 25.60p per kWh
Savings over 25 years: £23,564; Prices rising 3% a year
Installed cost: £5,157; Government median for 0–4 kW systems
Payback: 6.9 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.
