Bideford, England, United Kingdom is a moderately suitable location for year-round solar PV energy generation, though it faces the typical challenges of the Northern Temperate Zone climate. The location shows significant seasonal variation in solar energy production potential.
Seasonal Solar Production Performance
Summer represents the peak solar generation period at Bideford, England, with panels producing 5.80kWh per day per kW of installed capacity. This is when solar panels operate at their highest efficiency due to longer days and stronger solar radiation. Spring follows as the second-best season with 4.96kWh per day per kW, making it nearly as productive as summer months. Autumn sees a notable decline in solar output, dropping to 2.16kWh per day per kW of installed solar capacity. Winter presents the most challenging conditions for solar generation, with output falling to just 0.99kWh per day per kW - less than one-fifth of summer production levels.Optimal Panel Configuration
For fixed panel installations at Bideford, England, the ideal tilt angle is 43 degrees facing south to maximize total year-round solar production. This angle is calculated to capture the most solar energy across all seasons by accounting for the sun's changing elevation throughout the year and weighting for actual solar irradiance data.Local Environmental and Weather Challenges
Several factors specific to Bideford's coastal location in Devon can impact solar panel performance:- High humidity and frequent precipitation typical of the UK's maritime climate can reduce solar irradiance
- Coastal salt air exposure may cause corrosion and reduce panel efficiency over time
- Cloud cover and overcast conditions common in this region significantly reduce solar radiation
- Strong coastal winds can create additional stress on mounting systems
Preventative Installation Measures
To maximize solar energy production despite these challenges, several installation strategies should be considered:- Use marine-grade mounting hardware and corrosion-resistant materials to withstand salt air exposure
- Install panels with adequate spacing for natural rainwater cleaning and proper drainage
- Choose high-quality panels with anti-reflective coatings that perform better in diffuse light conditions
- Ensure robust mounting systems designed for high wind loads typical of coastal areas
- Consider regular maintenance schedules for cleaning panels, especially during autumn and winter months

Solar output per kW of installed solar PV by season in Bideford
Seasonal solar PV output for Latitude: 51.0178, Longitude: -4.2032 (Bideford, 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 Bideford, United Kingdom
To maximize your solar PV system's energy output in Bideford, United Kingdom (Lat/Long 51.0178, -4.2032) 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 Bideford, 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 Bideford, 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 | 64° 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 Bideford, 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 Bideford, 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 Bideford, United Kingdom
Topography Around Bideford
Bideford sits in a distinctive geographical setting in North Devon, positioned along the estuary of the River Torridge as it flows toward the Atlantic Ocean. The town itself occupies relatively low-lying ground, with the historic center built on gentle slopes rising from the riverside. The immediate landscape is characterized by rolling hills that create a varied terrain typical of Devon's countryside. To the north of Bideford, the land gradually rises toward the dramatic coastline of Bideford Bay and the Bristol Channel. This coastal region features a mix of agricultural fields, scattered woodlands, and small settlements connected by winding country lanes. The terrain becomes more undulating as it approaches the coast, with some steeper sections near cliff areas, though much of the agricultural land maintains gentle to moderate slopes. Eastward from the town, the topography transitions into the broader Devon countryside, where the landscape consists of medium-sized fields divided by traditional hedgerows and occasional copses. The terrain here shows the characteristic rolling nature of Devon's inland areas, with valleys carved by smaller tributaries of the Torridge and intervening ridges that rarely exceed significant elevation. South and southwest of Bideford, the land continues this pattern of gentle hills and valleys, extending toward the western edges of Dartmoor in the far distance. The immediate area features good quality agricultural land with relatively open aspects, interrupted by small villages and farmsteads typical of rural Devon.Optimal Areas for Large-Scale Solar Development
The most promising locations for substantial solar photovoltaic installations lie in the gently sloping agricultural areas to the east and southeast of Bideford. These zones offer several advantages including relatively consistent terrain that would minimize grading requirements, good accessibility via existing road networks, and sufficient distance from the most sensitive coastal and estuarine environments. The rolling farmland extending toward the A39 corridor presents particularly suitable conditions, with field sizes that could accommodate large arrays while maintaining appropriate setbacks from residential areas. The moderate southerly aspects common in this area would provide favorable solar exposure, while the existing agricultural use suggests fewer environmental constraints compared to more sensitive habitats. Areas north of the town, while topographically suitable in places, present greater challenges due to proximity to the coast and associated landscape designations. The immediate coastal zone carries additional planning considerations that would likely complicate large-scale development, though smaller installations might remain viable. The western approaches to Bideford, toward the Torridge estuary, generally offer less suitable conditions due to the combination of flood risk considerations, ecological sensitivity of estuarine environments, and more fragmented land ownership patterns typical of areas closer to water bodies. Agricultural land with good transport links, particularly areas accessible from major roads without requiring passage through residential areas, would provide the most practical development opportunities. The gentle topography characteristic of much of Devon's farmland in this region means that large-scale solar installations could be developed with minimal earthworks while maintaining effective drainage patterns.United Kingdom solar PV Stats as a country
