Carshalton, England, located in the United Kingdom, offers a moderate potential for solar energy generation throughout the year. Situated in the Northern Temperate Zone, this location experiences significant seasonal variations in solar output.
Seasonal Solar Performance
Summer stands out as the most productive season for solar energy in Carshalton, England, with an average daily output of 5.13 kWh per kW of installed solar capacity. Spring follows closely behind, generating 4.36 kWh/day. However, the output drops considerably during autumn (2.31 kWh/day) and reaches its lowest point in winter (1.07 kWh/day).
The substantial difference between summer and winter production highlights the impact of seasonal changes on solar energy generation in this region. The longer daylight hours and higher sun angles during summer contribute to the increased output, while shorter days and lower sun angles in winter result in reduced production.
Optimal Panel Installation
To maximize year-round solar energy production in Carshalton, England, fixed solar panels should be installed at a tilt angle of 44 degrees facing south. This angle is calculated to optimize the capture of available sunlight throughout the year, considering the location's latitude and seasonal sun positions.
Environmental and Weather Factors
Several factors can impact solar energy production in Carshalton:
- Cloud cover: The UK is known for its cloudy weather, which can significantly reduce solar output.
- Rainfall: Frequent rain can temporarily decrease panel efficiency, although it can also help clean the panels.
To mitigate these factors, consider installing high-efficiency panels that perform well in low-light conditions. Regular cleaning and maintenance of panels can also help maintain optimal performance. Additionally, using microinverters or power optimizers can minimize the impact of partial shading on overall system output.
In conclusion, while Carshalton's location presents challenges for year-round solar energy production, proper system design and installation can still yield satisfactory results, particularly during the spring and summer months.

Ideally tilt fixed solar panels 44° South in Carshalton, United Kingdom
To maximize your solar PV system's energy output in Carshalton, United Kingdom (Lat/Long 51.3655, -0.1632) 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 Carshalton, 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 Carshalton, 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 | 54° South in Autumn | 65° South in Winter | 43° 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 Carshalton, 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 Carshalton, 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 Carshalton, United Kingdom
Carshalton, located in the London Borough of Sutton, is situated in a relatively flat area with gentle undulations typical of the London Basin. The surrounding landscape is characterized by low-lying terrain, with subtle variations in elevation throughout the region. The area around Carshalton features a mix of urban development and green spaces. To the north and east, the terrain is predominantly flat, with residential areas and small parks dotting the landscape. The southern part of Carshalton sees a slight increase in elevation as it approaches the North Downs, a ridge of chalk hills that runs through Surrey and Kent.
Notable Topographical Features
One of the most prominent topographical features in Carshalton is the Wandle Valley, which runs through the western part of the area. This shallow river valley creates a gentle depression in the landscape, with the River Wandle flowing northwards towards the Thames. To the southwest of Carshalton, the land begins to rise more noticeably as it approaches the Surrey Hills. This area, while still relatively gentle in its slopes, offers more varied terrain compared to the flatter northern regions.Potential for Solar PV Installation
When considering areas nearby that would be most suited to large-scale solar PV installations, several factors come into play. The ideal location would have relatively flat or gently sloping land, good sun exposure, and minimal shading from trees or buildings. Given these criteria, the areas to the north and east of Carshalton might be more suitable for large-scale solar PV projects. These regions tend to be flatter and have fewer obstructions that could cast shadows on solar panels. The open fields and agricultural lands in these directions could potentially accommodate larger installations. However, it's important to note that the entire region around Carshalton is heavily urbanized, which limits the available space for large-scale solar projects. Any significant solar PV installation would likely need to be located further out from the town center, possibly in the more rural areas to the south or southeast where there might be larger tracts of open land available. The gentle slopes found in the areas approaching the North Downs to the south could also be considered for solar PV installations, as they may provide good sun exposure throughout the day. However, careful site selection would be necessary to avoid areas with significant tree cover or other obstructions that could reduce the efficiency of the solar panels. Ultimately, while the topography around Carshalton is generally favorable for solar PV installations, the high level of urban development in the immediate vicinity may pose challenges for large-scale projects. Detailed site surveys and planning would be essential to identify the most suitable locations for significant solar energy development in this region.United Kingdom solar PV Stats as a country
