The location at Trowbridge, England, United Kingdom is not ideal for generating energy via solar PV year-round due to its position in the Northern Temperate Zone. However, it still has potential for solar energy production during certain times of the year.
During summer and spring, you can expect a decent amount of electricity output - 5.42kWh/day and 4.54kWh/day respectively per kW of installed solar. This means that these seasons are the most ideal times to generate solar power in this location because longer daylight hours and stronger sun intensity result in more energy produced.
In contrast, autumn and winter have significantly lower outputs at 2.31 kWh/day and 1.05 kWh/day respectively per kW of installed solar due to shorter days and weaker sunlight intensity.
For a fixed panel installation at this location, tilting panels at an angle of 43 degrees South would maximize total year-round production from solar PV as it aligns with the sun's path across the sky throughout different seasons.
There could be environmental or weather factors that may impede solar production such as heavy cloud cover or rain which are common in UK's climate especially during autumn/winter months reducing sunlight exposure on panels. Additionally, dust or debris accumulation on panels can also reduce their efficiency over time.
Preventative measures include regular cleaning/maintenance of panels to ensure they remain clear from obstructions like dust/debris; using advanced tracking systems that move panels according to sun’s position for maximum sunlight exposure; installing additional storage batteries for storing excess power generated during peak hours (summer/spring) which can then be used when production is low (autumn/winter).
Please note though while these measures can help improve efficiency they will also increase initial setup costs so it’s important to consider them carefully against potential benefits before making a final decision about installing a Solar PV system.
Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.
So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 911 locations across United Kingdom. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

Solar output per kW of installed solar PV by season in Trowbridge
Seasonal solar PV output for Latitude: 51.3188, Longitude: -2.2034 (Trowbridge, 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 Trowbridge, United Kingdom
To maximize your solar PV system's energy output in Trowbridge, United Kingdom (Lat/Long 51.3188, -2.2034) 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 Trowbridge, 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 Trowbridge, 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 | 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 Trowbridge, 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 Trowbridge, 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 Trowbridge, United Kingdom
Trowbridge, United Kingdom is located in the county of Wiltshire and is surrounded by a mix of urban areas, farmland, and rolling hills. The region has a relatively moderate to low relief with few high elevations or steep slopes. It's generally characterized by open fields, pastures and woodland.
As for largescale solar PV installations, they require large tracts of land that are relatively flat and receive ample sunlight throughout the year. In this context:
1) Farmlands: There are several farmlands around Trowbridge that could potentially be used for solar farms without causing significant disruption to local ecosystems or biodiversity.
2) Brownfield Sites: These are previously developed sites that may have been abandoned or underused. They can often be repurposed for renewable energy projects like solar farms.
3) Industrial Areas: Large industrial zones or warehouses with vast roof spaces can also be ideal locations for installing rooftop solar panels.
4) Landfills/Disused Quarries: These types of locations can also offer suitable conditions for large-scale solar installations as they typically have minimal shading issues and are not usually suitable for other forms of development due to their previous uses.
However, it's important to note that any proposed site would need careful assessment considering factors such as grid connectivity possibilities, potential environmental impacts, local planning regulations etc., before proceeding with an installation.
United Kingdom solar PV Stats as a country
United Kingdom ranks 14th in the world for cumulative solar PV capacity, with 13,689 total MW's of solar PV installed. This means that 4.00% of United Kingdom's total energy as a country comes from solar PV (that's 20th in the world). Each year United Kingdom is generating 203 Watts from solar PV per capita (United Kingdom ranks 25th in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in United Kingdom?
Yes, there are several incentives for businesses wanting to install solar energy in the United Kingdom. The UK government offers a Feed-in Tariff (FiT) scheme which pays businesses for every unit of electricity they generate from their solar panels. Additionally, businesses may be eligible for tax reliefs such as Enhanced Capital Allowances and Renewable Heat Incentives. Finally, some local authorities offer grants or other financial support to help businesses with the cost of installing solar energy systems.
