Solar Panels in Bristol

A south-facing roof in Bristol generates about 1,022 kWh per kWp a year on the EU's PVGIS model, and every unit you use saves 26.58p at the South Western England price cap rate. A typical 4.5kWp system would make about 4,599 kWh a year.

How much electricity solar panels make in Bristol

A south-facing 1kWp system at 35 degrees in central Bristol generates about 1,022 kWh a year, according to the EU's PVGIS model. That ranks 10 of the 20 areas we cover, which run from 850 kWh in Glasgow to 1,119 kWh in Dorset. East and west roofs still work, at roughly a fifth less.

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 Bristol

Every unit you use yourself saves 26.58p, the Ofgem price cap rate for direct debit customers in the South Western 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 Bristol it would generate about 4,599 kWh a year. If you used all of it, that would be worth about £1,222. If you exported all of it, about £552. 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.

Listed homes in Clifton: a blanket consent for solar

Bristol has a Local Listed Building Consent Order for solar panels in the Clifton Conservation Area, endorsed by the council's planning committee in July 2025. It gives conditional consent for qualifying households to put panels on the roofs of listed buildings, so you do not need your own listed building consent application. For one of the most heavily listed parts of the city, that removes the biggest obstacle to rooftop solar. Our guide to solar panels on a listed building lists the other councils with similar orders.

Elsewhere, Bristol's planning page sets out when you need permission: if panels stick out more than 20cm, sit above the highest part of the roof, go on a road-facing wall in a conservation area, or are on a listed building. The city has 33 conservation areas. Our guide to permitted development for solar panels has the national rules.

Grants and free advice in Bristol

Bristol's main solar grant, Bright Green Homes from Bristol City Leap, is closed to new applications because of high demand. While it was open it funded solar panels and battery storage for homes rated EPC D to G with a household income of £36,000 or less. Check the City Leap page in case it reopens.

What is open is Retrofit West, funded by the West of England Mayoral Combined Authority, which gives Bristol homeowners free, independent advice on upgrades including solar panels. When we checked, it was also offering 50% off home energy assessments until 31 December. Our guide to solar panel grants in the UK covers the national schemes.

How much solar Bristol has, and how much it could have

The government counted 10,725 solar installations in Bristol at the end of 2025, up from 9,908 a year earlier. That is about 56 per 1,000 households by our count, below the UK average of about 69. The government warns its 2025 council figures undercount, because some recent installations have not yet been matched to an area. North West Bristol leads the city on the government's domestic figures for August 2026.

Bristol City Council estimates the city's total rooftop solar potential at around 500 MW, and its One City Climate Strategy aims for around 350 MW. With 32.1% of Bristol households in terraced houses at the 2021 Census, against 23.0% across England, many of those roofs are small. A terraced roof usually takes fewer panels, so ask installers how they would lay out yours.

Your network operator in Bristol

Bristol's network is run by National Grid Electricity Distribution, and notification must reach it within 28 days of your system being commissioned. National Grid is spending £25 million upgrading overhead lines on a 14-mile route into east Bristol, citing rising demand from solar panels, heat pumps, EV chargers and batteries. See our G98 and G99 guide. Also in the South West, see solar panels in Cornwall, or compare solar panels in London.

Getting solar quotes in Bristol

Get at least three written quotes from MCS-certified installers, each with a performance estimate for your roof and a full breakdown of what is supplied. That is the Renewable Energy Consumer Code's advice. Never pay more than 25% up front, and walk away from anyone offering a discount to sign on the day. Our guide to choosing a solar installer covers what to check.
