Solar panels tilted 75 degrees
The best all-year-round angle for PV (photovoltaic) solar panels in the UK is 35-40 degrees. The best angle for each region within the UK will vary slightly within this. For seasonal changes, the best angle for summertime is 20 degrees and 50 degrees in winter. See below for the optimum angle for each UK region. If you have a solar system that can move with the seasons, whether manually or automatically, you will need to calculate the tilt according to the time of year. For example, you will want. For winter work out your solar panel tilt by adding 15 to your latitude. So, if your latitude is 34. 34 + 15 = 49. Your solar panels need a 49-degree tilt. If you're still learning about solar, refer to our complete advice section for more. For summer you can do this by subtracting 15. For example, 34 -15 = 19. You would want a 19-degree tilt.
