A south-facing roof is usually the best direction for solar panels in the UK. This orientation produces the highest annual electricity output. However, south-east and south-west roofs are still highly effective and often only slightly less productive. If you are unsure how your roof performs, you can compare real options using the [solar panel comparison tool](https://kilowatts.uk/services/residential/renewable-energy/residential-solar-panel-installation/compare/ "solar panel comparison tool") or explore installers in the [electrician directory](https://kilowatts.uk/electrical-companies/ "electrician directory"). ## Why south-facing panels work best in the UK The UK sits in the northern hemisphere, so the sun travels across the southern part of the sky. Panels facing south receive the most consistent sunlight throughout the day. Most systems in southern England achieve their highest output when facing due south at a tilt of around 30 to 40 degrees. - ### Maximum annual yield South-facing systems typically generate the most electricity over a full year. - ### Strong export potential Higher generation supports better export through schemes like the Smart Export Guarantee. - ### Balanced sunlight exposure Energy production is spread evenly from morning to afternoon. ## How much difference direction actually makes Not all roofs can face south, but the performance difference is often smaller than expected. This means many UK homes can still benefit from solar even without a perfect orientation. You can review different system designs through the [renewable energy services section](https://kilowatts.uk/services/ "renewable energy services section") to understand realistic outcomes. - ### East or west Typically 10 to 20 percent lower annual output. - ### North-facing Often 30 to 50 percent lower, depending on pitch and shading. - ### South-east or south-west Usually 5 to 10 percent less generation than south. ## East vs west vs south explained Different directions change when electricity is produced, not just how much. This can matter depending on your usage. Homes with higher evening demand may benefit from west-facing panels, while daytime users may prefer south-facing systems. - ### East-facing Generates more electricity in the morning. - ### West-facing Produces more in the afternoon and evening. - ### South-facing Produces energy consistently throughout the day. ## The role of roof pitch and angle Direction alone does not determine performance. Roof pitch has a major impact on energy generation. Flat roofs allow mounting systems to adjust both tilt and direction, giving more flexibility in design. - ### Ideal pitch Around 30 to 40 degrees for most of the UK. - ### Flatter roofs Reduce winter generation due to low sun angles. - ### Steeper roofs Can reduce summer efficiency. ## When south is not the best financial option The highest generation does not always mean the best financial return. If you are considering storage, explore [battery storage options](https://kilowatts.uk/services/residential/backup-systems/residential-whole-house-battery/# why-use-us "battery storage options") alongside solar to improve flexibility. - ### Battery storage Allows energy to be stored, reducing reliance on exact orientation. - ### East-west systems Can better match typical UK usage patterns. - ### Self-consumption patterns Energy used at home is often more valuable than exported energy. ## The impact of shading on direction Shading can reduce performance more than poor orientation. Even a perfectly south-facing system can underperform if shading is not addressed. - ### Partial shading May affect the entire system without optimisers. - ### Chimneys and trees Can block sunlight during key hours. - ### Urban environments Nearby buildings can reduce output significantly. ## Common misconceptions about solar direction Many homeowners assume solar only works on south-facing roofs. Modern system design tools consider all variables including postcode, roof angle, and shading. - ### Panels must face south False, east and west still perform well. - ### North-facing roofs are useless Not always, but usually less efficient. - ### Direction matters more than everything else Shading and system design can be more important. ![Comparison chart of solar panel output by roof direction in the UK, showing performance differences between south, south-east, south-west, east, west, and north.](/uploads_resolved/images/176/320.webp) ## Can I still get solar if my roof is not south-facing? Yes, many UK homes install solar successfully on east or west-facing roofs with good results. ## Direction comparison at a glance - ### East Strong morning generation - ### West Better afternoon and evening generation - ### North Lowest output and usually least suitable - ### South Highest annual output and balanced generation - ### South-east or south-west Slightly lower output but still highly effective ### Ready to compare your options?

We’ve Got Answers What is the best direction for solar panels in the UK? South-facing is generally the best direction because it produces the highest annual energy output due to consistent sunlight throughout the day. Are south-east and south-west roofs still effective? Yes, south-east and south-west facing roofs are still highly effective and usually only slightly less productive than a south-facing system. Why do south-facing panels work best in the UK? The UK is in the northern hemisphere, so the sun travels across the southern part of the sky, allowing south-facing panels to capture the most sunlight throughout the day. How much does direction really affect solar performance? Direction does affect performance, but often less than people expect. Many homes still achieve strong results even if their roof is not perfectly south-facing. Is it worth installing solar panels on an east or west-facing roof? Yes, east and west-facing panels can still perform well and may better match your energy usage depending on when you use electricity. Do different directions affect when electricity is generated? Yes, south-facing panels generate more evenly throughout the day, east-facing panels produce more in the morning, and west-facing panels generate more in the evening. Does roof pitch matter as much as direction? Yes, roof angle plays a major role. A pitch of around 30 to 40 degrees is typically ideal for maximising solar output in the UK. Can flat roofs work for solar panels? Yes, flat roofs can use mounting systems to adjust both the tilt and direction of panels, offering more flexibility in design. Is south-facing always the best financial option? Not always. While it produces the most energy, the best financial return depends on your energy usage and whether you include options like battery storage. How does shading affect solar panel performance? Shading can significantly reduce performance and may have a greater impact than direction, even on a south-facing system. Do solar panels only work on south-facing roofs? No, modern systems can work effectively on east and west-facing roofs, and even north-facing roofs may still be viable in some situations. How much less efficient are north-facing panels? North-facing panels can produce significantly less energy, typically around 30 to 50 percent lower than south-facing systems, but they may still be usable depending on the setup. Can I compare solar options for my home? Yes, you can use the [solar panel comparison tool](https://kilowatts.uk/services/residential/renewable-energy/residential-solar-panel-installation/compare/) to explore real options and find suitable installers.
