Ruislip, England, located in the United Kingdom, presents a mixed scenario for solar PV energy generation throughout the year. Situated in the Northern Temperate Zone, this location experiences significant seasonal variations in solar output.
Seasonal Performance
Summer stands out as the most productive season, with an impressive 5.13 kWh per day for each kilowatt of installed solar capacity. Spring follows closely, generating 4.36 kWh/day. However, the output drops considerably during autumn, producing only 2.31 kWh/day. Winter sees the lowest generation, with a mere 1.07 kWh/day.
These figures highlight that Ruislip's solar potential is heavily skewed towards the warmer months. The period from late spring through early autumn offers the most favorable conditions for solar energy production.
Optimal Panel Configuration
To maximize year-round solar energy production in Ruislip, England, fixed solar panels should be tilted at a 44-degree angle facing south. This orientation helps capture the most sunlight throughout the year, considering the location's latitude and seasonal sun angles.
Environmental Factors and Mitigation
While Ruislip's location is generally suitable for solar energy, there are some environmental factors to consider:
- Cloud cover: The UK is known for its frequent overcast conditions, which can significantly reduce solar output. Using high-efficiency panels and microinverters can help mitigate this issue.
- Rain and humidity: Regular rainfall can lead to dirt accumulation on panels. Installing self-cleaning panels or implementing a regular cleaning schedule can maintain optimal performance.
Additionally, ensuring that panels are not shaded by nearby trees or buildings is crucial for maximizing energy production. Regular maintenance and monitoring of the system can help identify and address any performance issues promptly.
In conclusion, while Ruislip's solar potential varies greatly between seasons, proper panel orientation and addressing environmental factors can still make solar PV a viable energy option, especially during the longer, sunnier days of spring and summer.
Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.

Solar output per kW of installed solar PV by season in Ruislip
Seasonal solar PV output for Latitude: 51.5758, Longitude: -0.4248 (Ruislip, United Kingdom), based on our analysis of 8760 hourly intervals of solar and meteorological data (one whole year) retrieved for that set of coordinates/location from NASA POWER (The Prediction of Worldwide Energy Resources) API:




 
Ideally tilt fixed solar panels 44° South in Ruislip, United Kingdom
To maximize your solar PV system's energy output in Ruislip, United Kingdom (Lat/Long 51.5758, -0.4248) throughout the year, you should tilt your panels at an angle of 44° South for fixed panel installations.
As the Earth revolves around the Sun each year, the maximum angle of elevation of the Sun varies by +/- 23.45 degrees from its equinox elevation angle for a particular latitude. Finding the exact optimal angle to maximise solar PV production throughout the year can be challenging, but with careful consideration of historical solar energy and meteorological data for a certain location, it can be done precisely.
We use our own calculation, which incorporates NASA solar and meteorological data for the exact Lat/Long coordinates, to determine the ideal tilt angle of a solar panel that will yield maximum annual solar output. We calculate the optimal angle for each day of the year, taking into account its contribution to the yearly total PV potential at that specific location.

Seasonally adjusted solar panel tilt angles for Ruislip, United Kingdom
If you can adjust the tilt angle of your solar PV panels, please refer to the seasonal tilt angles below for optimal solar energy production in Ruislip, United Kingdom. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 44° South tilt angle throughout the year.
Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
---|---|---|---|
35° South in Summer | 55° South in Autumn | 65° South in Winter | 44° South in Spring |
Our recommendations take into account more than just latitude and Earth's position in its elliptical orbit around the Sun. We also incorporate historical solar and meteorological data from NASA's Prediction of Worldwide Energy Resources (POWER) API to assign a weight to each ideal angle for each day based on its historical contribution to overall solar PV potential during a specific season.
This approach allows us to provide much more accurate recommendations than relying solely on latitude, as it considers unique weather conditions in different locations sharing the same latitude worldwide.
Calculate solar panel row spacing in Ruislip, United Kingdom
We've added a feature to calculate minimum solar panel row spacing by location. Enter your panel size and orientation below to get the minimum spacing in Ruislip, United Kingdom.
Our calculation method
- Solar Position:
We determine the Sun's position on the Winter solstice using the location's latitude and solar declination. - Shadow Projection:
We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle. - Minimum Spacing:
We add the shadow length to the horizontal space occupied by tilted panels.
This approach ensures maximum space efficiency while avoiding shading during critical times, as the Winter solstice represents the worst-case scenario for shadow length.
Topography for solar PV around Ruislip, United Kingdom
Ruislip, located in the London Borough of Hillingdon, is situated in a relatively flat area with gentle undulations typical of the London Basin. The topography of Ruislip and its surrounding areas is characterized by low-lying terrain, with elevations generally ranging from 40 to 60 meters above sea level. The landscape is a mix of urban development, suburban neighborhoods, and pockets of green spaces. To the north and west of Ruislip, the land gradually rises towards the Chiltern Hills, forming a series of subtle ridges and valleys. This area includes the Ruislip Woods National Nature Reserve, which features slight variations in elevation due to its ancient woodland character. To the south and east, the terrain remains predominantly flat, with occasional small hills and depressions. The area is dotted with several water bodies, including the Ruislip Lido, a large artificial lake, and the River Pinn, which flows through the region. These features contribute to minor variations in the local topography, creating shallow valleys and gentle slopes along their banks.
Potential Areas for Large-scale Solar PV
When considering areas nearby that would be most suited to large-scale solar PV installations, several factors come into play, including available open space, minimal shading, and favorable orientation. Given the relatively flat terrain of the region, there are a few potential areas that could be considered: Former agricultural lands to the north and west of Ruislip, particularly in areas where the landscape opens up beyond the suburban development, could offer suitable sites for solar farms. These areas generally have fewer obstructions and could provide the necessary space for large-scale installations. The expansive grounds of RAF Northolt, located to the south of Ruislip, might also be considered for solar PV deployment. Military installations often have large, open areas that could potentially accommodate solar panels without interfering with operations. Areas along the M25 motorway corridor, particularly in less developed sections to the west and northwest of Ruislip, could be potential candidates for solar farms. These locations often have the advantage of existing infrastructure and minimal residential development nearby. It's important to note that while the topography around Ruislip is generally favorable for solar PV installations, other factors such as local planning regulations, environmental considerations, and grid connection capabilities would need to be carefully evaluated before any large-scale solar projects could be implemented in these areas.United Kingdom solar PV Stats as a country
