Crowthorne, England, United Kingdom, situated in the Northern Temperate Zone, presents a mixed outlook for solar PV energy generation. This location experiences significant seasonal variations in solar energy production, which impacts the overall efficiency of solar installations throughout the year.

Seasonal Solar Performance

Summer stands out as the most productive season for solar energy in Crowthorne, England, with an impressive output of 5.13 kWh per day for each kilowatt of installed solar capacity. Spring follows closely behind, generating 4.36 kWh/day. However, the performance drops considerably during autumn, with 2.31 kWh/day, and reaches its lowest point in winter, producing only 1.07 kWh/day.

These figures highlight the stark contrast between the warm and cold seasons, with summer producing nearly five times more energy than winter. This variation is primarily due to the changing daylight hours and sun angle throughout the year.

Optimal Panel Placement

To maximize year-round solar energy production in Crowthorne, England, 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 location's latitude and the Earth's elliptical orbit.

Environmental Factors and Mitigation

While Crowthorne's location is generally suitable for solar energy production, there are some environmental factors that could impact efficiency:

• Cloud cover: The UK is known for its cloudy weather, which can reduce solar panel efficiency. Using high-quality panels designed to perform well in diffuse light conditions can help mitigate this issue.
• Rain and humidity: Frequent rainfall can lead to dirt accumulation on panels. Installing self-cleaning panels or implementing regular cleaning schedules can maintain optimal performance.

Despite these challenges, proper installation techniques and regular maintenance can help ensure consistent energy production throughout the year. While winter months may see reduced output, the extended daylight hours during summer can significantly boost overall annual energy generation.

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 Crowthorne

Seasonal solar PV output for Latitude: 51.367, Longitude: -0.8042 (Crowthorne, 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 Crowthorne, United Kingdom

To maximize your solar PV system's energy output in Crowthorne, United Kingdom (Lat/Long 51.367, -0.8042) 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 Crowthorne, 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 Crowthorne, 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 Crowthorne, 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 Crowthorne, 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 Crowthorne, United Kingdom

Crowthorne, located in Berkshire, England, is situated in an area characterized by gently rolling terrain typical of the Thames Valley region. The landscape around Crowthorne is a mix of low hills, shallow valleys, and relatively flat areas, with elevations generally ranging from about 50 to 90 meters above sea level. The topography in this area has been shaped by centuries of human activity, including agriculture and forestry. To the north and east of Crowthorne, you'll find more open, flatter areas interspersed with pockets of woodland. The famous Swinley Forest lies to the east, providing a slightly more undulating landscape with areas of dense tree cover. To the south and west, the terrain becomes a bit more varied, with some steeper slopes and more pronounced hills. This area includes parts of the North Downs, a ridge of chalk hills that extends from Farnham in Surrey to the White Cliffs of Dover in Kent.

Potential for Large-Scale Solar PV

When considering areas nearby that would be most suited to large-scale solar PV installations, several factors come into play. Ideal locations for solar farms typically include flat or gently sloping land with good exposure to sunlight and minimal shading from trees or buildings. The areas to the north and east of Crowthorne, where the terrain is generally flatter and more open, could potentially be suitable for solar PV development. These areas often include agricultural land or former industrial sites that might be repurposed for renewable energy production. Specific locations that might be worth investigating include: 1. The open fields between Crowthorne and Bracknell to the north 2. Areas around Wokingham to the northwest, where there are expanses of relatively flat agricultural land 3. Some of the less densely forested areas to the east, towards Ascot It's important to note that any large-scale solar PV development would need to carefully consider environmental impacts, local planning regulations, and grid connection possibilities. The proximity to populated areas and existing infrastructure in this region could be advantageous for connecting new solar installations to the power grid. While the rolling hills to the south and west might seem attractive for their elevation, they may present challenges in terms of installation and may have more significant visual impacts on the landscape. Therefore, the flatter areas to the north and east are likely to be more suitable overall for large-scale solar PV projects in the vicinity of Crowthorne.
