Graph of hourly avg kWh electricity output per kW of Solar PV installed in Bristol, United Kingdom (by season)

In Bristol, England, United Kingdom (latitude: 51.5105, longitude: -2.7013), solar power generation is relatively favorable throughout the year, with higher average daily energy production in summer (5.42 kWh) and spring (4.54 kWh) compared to autumn (2.31 kWh) and winter (1.05 kWh). This can be attributed to the city's location within the Northern Temperate Zone, which experiences longer daylight hours during summer and spring months.

For a fixed panel installation at this location, an optimal tilt angle of 44 degrees South would maximize solar energy production. However, certain environmental factors may impact solar power generation in Bristol.

Weather conditions such as heavy rain or snowfall could hinder solar energy production due to reduced sunlight exposure caused by cloud cover or precipitation obstructing the sun's rays from reaching the panels. To mitigate these effects, it is essential to ensure proper drainage around the installation site and consider using panels with anti-reflective coatings that can help capture more light under cloudy conditions.

Additionally, strong winds may lead to dust accumulation on the panels' surface, reducing their efficiency over time if not cleaned regularly. Installing wind barriers or choosing a sheltered location for panel installation can help minimize dust buildup while regular maintenance ensures optimal performance.

Overall, Bristol offers suitable conditions for generating solar power year-round; however, taking preventative measures against weather-related challenges will further enhance energy production at this location.

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 763 locations across United Kingdom. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

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

To maximize your solar PV system's energy output in Bristol, United Kingdom (Lat/Long 51.5105, -2.7013) 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.

At Latitude: 51.5105, Longitude: -2.7013, the ideal angle to tilt panels is 44° South

Seasonally adjusted solar panel tilt angles for Bristol, 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 Bristol, 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

Assuming you can modify the tilt angle of your solar PV panels throughout the year, you can optimize your solar generation in Bristol, United Kingdom as follows: In Summer, set the angle of your panels to 35° facing South. In Autumn, tilt panels to 55° facing South for maximum generation. During Winter, adjust your solar panels to a 65° angle towards the South for optimal energy production. Lastly, in Spring, position your panels at a 43° angle facing South to capture the most solar energy in Bristol, United Kingdom.

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 Bristol, 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 Bristol, 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.






Please enter information above to calculate panel spacing.

Topography for solar PV around Bristol, United Kingdom

The topography around Bristol, United Kingdom is generally quite flat. Areas to the south of the city are slightly more hilly and there are some small hills to the east and west. The most suitable areas for large-scale solar PV in the vicinity of Bristol would be open, flat land with good access to sunlight. Areas such as farmland, industrial estates or disused airfields could all be well suited for this purpose.

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.
