Solar PV Analysis of Chatham, United Kingdom
Chatham, located in Kent, England, presents a mixed picture for solar energy generation throughout the year. Situated in the Northern Temperate Zone, this location experiences significant seasonal variations in solar output.
Seasonal Solar Performance
Summer stands out as the most productive season for solar energy in Chatham, with an impressive daily output of 5.13 kWh per kW of installed solar capacity. Spring follows closely behind, generating 4.41 kWh/day. However, the performance drops considerably during autumn, with 2.29 kWh/day, and reaches its lowest point in winter, producing only 1.03 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 day length and sun angle throughout the year at Chatham's latitude.
Optimal Panel Installation
To maximize year-round solar energy production in Chatham, 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 sun's changing position and the Earth's elliptical orbit.
Environmental and Weather Factors
While Chatham's location is generally favorable for solar energy production, there are some environmental factors to consider:
- Cloud cover: The UK is known for its cloudy weather, which can significantly reduce solar output, especially during autumn and winter.
- Rainfall: Frequent rain can lead to dirt accumulation on panels, potentially reducing efficiency.
To mitigate these factors, consider installing self-cleaning panels or implementing a regular cleaning schedule. Additionally, using high-efficiency panels can help maximize energy production even during periods of reduced sunlight.
In conclusion, while Chatham's location presents challenges for year-round solar energy production, particularly in winter, the strong performance during spring and summer makes it a viable option for renewable energy generation. With proper installation and maintenance, solar PV systems can still provide significant benefits to households and businesses in the area.

Solar output per kW of installed solar PV by season in Chatham
Seasonal solar PV output for Latitude: 51.3537, Longitude: 0.5287 (Chatham, 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 Chatham, United Kingdom
To maximize your solar PV system's energy output in Chatham, United Kingdom (Lat/Long 51.3537, 0.5287) 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 Chatham, 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 Chatham, 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 Chatham, 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 Chatham, 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 Chatham, United Kingdom
The area around Chatham, United Kingdom, is characterized by gently rolling hills and low-lying plains typical of the North Downs region in Kent. The town itself is situated on the southern bank of the River Medway, which has carved a wide valley through the surrounding landscape. The terrain gradually rises as you move away from the river, with some steeper slopes and small valleys interspersed throughout the area.
To the north of Chatham, across the River Medway, you'll find the Hoo Peninsula, which is a relatively flat area with some gentle undulations. To the south and east, the land becomes more hilly, with a mix of open farmland, wooded areas, and small settlements dotting the countryside. The highest points in the vicinity are generally found to the south, where the North Downs begin to rise more prominently.
When considering areas nearby that would be most suited to large-scale solar PV (photovoltaic) installations, several factors come into play. Ideally, you'd want relatively flat or gently sloping land with good sun exposure and minimal shading from trees or buildings. Based on these criteria, some potentially suitable areas might include:
- The Hoo Peninsula to the north of Chatham: This area offers large, open spaces with relatively flat terrain, which could be ideal for solar farms.
- Agricultural land to the south and east of Chatham: While some of this area is hilly, there are pockets of flatter land that could accommodate solar installations.
- Brownfield sites or former industrial areas around Chatham and neighboring towns: These locations often provide large, open spaces that could be repurposed for solar energy production.
It's important to note that any large-scale solar PV project would need to consider additional factors such as grid connection availability, local planning regulations, and environmental impact assessments. The specific suitability of any site would require a detailed on-the-ground survey and consultation with local authorities and energy experts.
