Solar Energy Potential in Surrey, United Kingdom

Surrey, located in the southeastern part of England, has moderate potential for solar energy generation throughout the year. The location's position in the Northern Temperate Zone affects its solar energy production capabilities, with significant seasonal variations.

Seasonal Solar Output

Summer proves to be the most productive season for solar energy in Surrey, 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, there's a substantial drop in production during autumn and winter, with outputs of 2.31 kWh/day and 1.07 kWh/day, respectively.

Optimal Panel Positioning

To maximize year-round solar energy production in Surrey, fixed solar panels should be installed at a tilt angle of 44 degrees facing south. This angle has been calculated to optimize energy capture across all seasons, taking into account the Earth's elliptical orbit and the location's specific latitude.

Ideal Times for Solar Generation

The most favorable period for solar energy production in Surrey spans from late spring to early autumn. During these months, longer daylight hours and higher sun angles contribute to increased energy output. However, even during this optimal period, energy production can be affected by local weather conditions.

Challenges and Mitigation Strategies

Surrey's climate presents some challenges for solar energy production. The region experiences frequent cloud cover and rainfall, which can reduce solar panel efficiency. To mitigate these effects, consider the following measures:

• Use high-efficiency solar panels designed to perform well in diffuse light conditions
• Implement a robust cleaning schedule to remove dirt and debris that may accumulate on panels
• Install micro-inverters or power optimizers to minimize the impact of partial shading

Additionally, Surrey's temperate climate means that snow and ice are rarely significant issues. However, during occasional winter storms, it's advisable to have a plan for snow removal from panels to maintain energy production. By addressing these environmental factors and implementing appropriate preventative measures, solar energy systems in Surrey can achieve optimal performance despite the challenges posed by local weather conditions.

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 Surrey

Seasonal solar PV output for Latitude: 51.2589, Longitude: -0.5566 (Surrey, 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 Surrey, United Kingdom

To maximize your solar PV system's energy output in Surrey, United Kingdom (Lat/Long 51.2589, -0.5566) 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 Surrey, 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 Surrey, 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 Surrey, 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 Surrey, United Kingdom.

Our calculation method

1. Solar Position:
   We determine the Sun's position on the Winter solstice using the location's latitude and solar declination.
2. Shadow Projection:
   We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle.
3. 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 Surrey, United Kingdom

Surrey, located in southeastern England, is characterized by a diverse and picturesque topography. The county is part of the North Downs, a ridge of chalk hills that stretches from Farnham in the west to the White Cliffs of Dover in the east. This geological feature creates a landscape of rolling hills, steep escarpments, and verdant valleys. The northern part of Surrey is generally flatter, with gentle slopes and lowlands that gradually rise towards the south. As you move southward, the terrain becomes more undulating, with the North Downs forming a prominent ridge that runs east to west across the county. This ridge offers panoramic views of the surrounding countryside and creates a natural boundary between the more urbanized north and the rural south. In the western part of Surrey, you'll find the Surrey Hills Area of Outstanding Natural Beauty, which encompasses a variety of landscapes including chalk downland, woodland, and heathland. This area is known for its stunning vistas and includes notable high points such as Leith Hill, the highest point in southeastern England. The southern part of Surrey is characterized by the Low Weald, a region of clay and sandstone that creates a gentler, more pastoral landscape with scattered farms and woodlands. Rivers and streams crisscross the county, including the River Wey and the River Mole, which have carved out picturesque valleys over time.

Potential Areas for Large-scale Solar PV

When considering areas suitable for large-scale solar PV installations in Surrey, several factors need to be taken into account, including sunlight exposure, land availability, and environmental considerations. Given the topography of Surrey, the following areas might be most suitable: The northern lowlands of Surrey, particularly areas near towns like Woking and Guildford, could be potential candidates for solar farms. These areas are generally flatter and more open, which is ideal for maximizing sunlight exposure. Additionally, they are closer to urban centers, which could facilitate easier grid connection. Some parts of the Low Weald in southern Surrey might also be suitable for solar PV installations. While this area is more rural, it offers larger tracts of land that could potentially be repurposed for solar energy production. The gently rolling landscape in this region could still provide adequate sun exposure for solar panels. It's important to note that while the Surrey Hills offer excellent sun exposure due to their elevation, their designation as an Area of Outstanding Natural Beauty would likely preclude large-scale solar developments in this region. Similarly, heavily wooded areas or steep slopes throughout the county would not be ideal for solar farms. Any large-scale solar PV project in Surrey would need to carefully balance energy production goals with the preservation of the county's natural beauty and agricultural heritage. Brownfield sites, such as former industrial areas or disused airfields, could be particularly attractive for solar development as they would have less impact on the scenic landscape that Surrey is known for.
