Twickenham, England, United Kingdom, situated at latitude 51.443 and longitude -0.3295, presents a mixed picture for solar PV energy generation throughout the year. Located in the Northern Temperate Zone, this area experiences significant seasonal variations in solar output.

Seasonal Solar Performance

Summer stands out as the most productive season for solar energy in Twickenham, England, with an average daily output of 5.13 kWh per kW 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, and reaches its lowest point in winter with a mere 1.07 kWh/day.

These figures highlight the substantial difference between the peak and trough seasons, with summer generating nearly five times more energy than winter. This variation is primarily due to the changing daylight hours and sun angle throughout the year at Twickenham's latitude.

Optimal Panel Positioning

To maximize year-round solar energy production in Twickenham, England, fixed solar panels should be tilted at a 44-degree angle facing south. This orientation helps to capture the most sunlight possible across all seasons, balancing the low winter sun with the higher summer sun path.

Environmental and Weather Considerations

While Twickenham's location is generally favorable for solar energy, there are some factors that could impact production:

• Cloud cover: The UK is known for its cloudy weather, which can significantly reduce solar output.
• Rain and fog: Frequent precipitation and foggy conditions, especially in autumn and winter, can further diminish solar efficiency.

To mitigate these challenges, consider installing high-efficiency panels that perform well in low-light conditions. Additionally, implementing a robust cleaning schedule to remove dirt and debris can help maintain optimal performance, particularly during the less sunny months.

In conclusion, while Twickenham's solar potential varies greatly throughout the year, proper panel positioning and maintenance can help maximize energy production. The location is most ideal for solar generation from late spring through early autumn, with winter months presenting the greatest challenges.

Ideally tilt fixed solar panels 44° South in Twickenham, United Kingdom

To maximize your solar PV system's energy output in Twickenham, United Kingdom (Lat/Long 51.443, -0.3295) 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 Twickenham, 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 Twickenham, 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	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 Twickenham, 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 Twickenham, 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 Twickenham, United Kingdom

Twickenham, located in southwest London, sits within a relatively flat area along the River Thames. The topography of this region is characterized by gently rolling terrain with low-lying floodplains near the river. The landscape is predominantly urban and suburban, with a mix of residential areas, parks, and some remaining pockets of green space. The immediate surroundings of Twickenham feature subtle variations in elevation, with slight rises and dips in the terrain. However, there are no significant hills or steep slopes in the vicinity. The area's elevation generally ranges from about 5 to 20 meters above sea level, with the lowest points being closest to the River Thames.

Nearby Areas Suitable for Large-Scale Solar PV

When considering locations for large-scale solar photovoltaic (PV) installations near Twickenham, several factors must be taken into account. The ideal areas would have ample open space, minimal shading, and relatively flat terrain. While the urban nature of the region limits options, there are some potential areas that could be considered: The expansive grounds of nearby Hampton Court Palace, located just a few kilometers to the southwest, offer a sizeable area that could potentially accommodate solar panels. The open parklands and fields surrounding the palace provide flat terrain with minimal obstruction from trees or buildings. Another possibility lies in the numerous parks and recreational grounds scattered throughout the area. Richmond Park, situated to the southeast of Twickenham, is a vast expanse of open land that could potentially host solar installations in certain sections without significantly impacting its natural beauty or recreational use. The Kempton Park Racecourse, located to the west of Twickenham, presents another opportunity. Its large, open areas and relatively flat terrain make it a potential candidate for solar PV development, particularly in unused or underutilized portions of the property. It's important to note that while these areas may be physically suitable for solar PV installations, any such developments would need to carefully consider environmental impact, local regulations, and community concerns. The historic and natural significance of many of these sites would likely pose challenges to large-scale solar projects, necessitating creative solutions and careful planning to balance energy production with preservation of the local landscape and heritage.
