Radstock, a town in Somerset, England, presents a mixed picture for solar energy generation throughout the year. Located in the Northern Temperate Zone, this area experiences significant seasonal variations in solar potential.
Seasonal Solar Performance
Summer stands out as the most productive season for solar energy in Radstock, with an impressive daily output of 5.42kWh per kW of installed solar capacity. Spring follows closely behind, generating 4.54kWh/day. These seasons offer excellent conditions for solar power generation, with longer daylight hours and generally clearer skies.
However, the picture changes dramatically during autumn and winter. Autumn sees a substantial drop in production to 2.31kWh/day, while winter plummets to a mere 1.05kWh/day. This stark contrast highlights the challenges of relying solely on solar power in Radstock year-round.
Optimal Panel Installation
To maximize year-round solar energy production in Radstock, fixed solar panels should be tilted at a 43-degree angle facing south. This optimal angle takes into account the town's latitude and the sun's position throughout the year, ensuring the best possible energy capture across all seasons.
Environmental Considerations
While Radstock's location is generally favorable for solar energy, there are some environmental factors to consider. The region's climate, characterized by frequent cloudy and overcast conditions, can significantly impact solar production. Additionally, the area's relatively high rainfall could lead to reduced sunlight exposure.
To mitigate these challenges, several preventative measures can be taken during solar installation:
- Use high-efficiency solar panels that perform well in low-light conditions
- Install a robust cleaning system to combat the effects of rain and potential debris
- Consider incorporating solar tracking systems for increased energy capture
By implementing these strategies, solar installations in Radstock can maximize their energy production potential, despite the seasonal and environmental challenges present in the area.
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 Radstock
Seasonal solar PV output for Latitude: 51.2279, Longitude: -2.5261 (Radstock, 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 43° South in Radstock, United Kingdom
To maximize your solar PV system's energy output in Radstock, United Kingdom (Lat/Long 51.2279, -2.5261) throughout the year, you should tilt your panels at an angle of 43° 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 Radstock, 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 Radstock, United Kingdom. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 43° 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 Radstock, 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 Radstock, 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 Radstock, United Kingdom
The area around Radstock, located in Somerset, England, is characterized by gently rolling hills and shallow valleys typical of the region's rural landscape. Situated on the northern edge of the Mendip Hills, Radstock's topography is a mix of low-lying areas and modest elevations, creating a picturesque setting. The surrounding countryside features a patchwork of fields, pastures, and small woodlands, interspersed with narrow country lanes and scattered farmsteads. To the south and east, the land gradually rises towards the Mendip Hills, an Area of Outstanding Natural Beauty known for its limestone ridges and steep-sided valleys.
Potential Areas for Large-Scale Solar PV
When considering locations for large-scale solar photovoltaic (PV) installations near Radstock, several factors come into play. Ideal sites would have relatively flat or gently sloping terrain, good exposure to sunlight, and minimal shading from trees or buildings. The agricultural lands to the north and west of Radstock offer promising potential for solar PV development. These areas tend to be more open and less hilly, with fewer obstructions to block sunlight. The fields between Radstock and neighboring towns like Midsomer Norton and Paulton could be suitable, provided they are not designated as high-grade agricultural land or protected areas. Another possibility lies in the reclaimed land of former coal mining sites in the area. These brownfield locations, which may have limited alternative uses, could be repurposed for solar energy generation. The relatively flat and open nature of these sites makes them potentially ideal for large-scale solar installations. It's important to note that any solar PV development would need to consider local planning regulations, environmental impact assessments, and the preservation of the area's natural beauty. The proximity to the Mendip Hills AONB may limit options in certain directions, particularly to the south and southeast of Radstock. Ultimately, detailed site surveys and environmental studies would be necessary to identify the most suitable locations for large-scale solar PV installations in the Radstock area, balancing energy generation potential with landscape preservation and local community interests.United Kingdom solar PV Stats as a country
