Solar PV Analysis of Dunstable, United Kingdom
The location at Dunstable, England, United Kingdom, is somewhat suitable for generating energy through solar photovoltaic (PV) systems all year round. However, the effectiveness varies greatly depending on the season.
During the summer months, you can expect to generate about 5.13 kilowatt-hours (kWh) of electricity per day for each kilowatt (kW) of installed solar power. This makes summer an ideal time for solar energy production in Dunstable.
In autumn and spring, you'll see a decrease in output but it's still quite decent with around 2.31 kWh/day and 4.36 kWh/day respectively per kW of installed solar power.
Winter months are less productive due to shorter daylight hours and more cloud cover; during this season you can only expect about 1.07 kWh/day per kW of installed solar power.
If you're planning to install a fixed panel system at this location, tilting your panels at an angle of 44 degrees towards the South will help maximise your total yearly production from your solar PV system.
As far as environmental or weather factors that could affect your system's performance in Dunstable:
- The area experiences regular rainfall throughout the year which could lead to dirt accumulation on the panels reducing their efficiency.
- In winter months there may be snowfall that could cover up panels temporarily lowering their productivity.
- High winds might also pose a risk by potentially damaging equipment if not securely mounted.
To mitigate these issues:
- Regular cleaning should be done especially after heavy rainfalls or snowfalls to ensure maximum sunlight absorption.
- Using durable mounting systems resistant against high winds would also help protect your investment.
Overall while Dunstable isn't necessarily perfect for year-round high yield solar generation due to its seasonal variations and potential weather challenges; with proper installation techniques and maintenance it certainly offers potential particularly during sunnier periods like summer and spring!
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 Dunstable
Seasonal solar PV output for Latitude: 51.8771, Longitude: -0.5383 (Dunstable, 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 Dunstable, United Kingdom
To maximize your solar PV system's energy output in Dunstable, United Kingdom (Lat/Long 51.8771, -0.5383) 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 Dunstable, 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 Dunstable, 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 | 44° 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 Dunstable, 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 Dunstable, 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 Dunstable, United Kingdom
Dunstable is located in the Chiltern Hills, an area of outstanding natural beauty in southern England. The topography around Dunstable is characterized by gentle slopes and undulating hills with a mix of cultivated fields, pastureland, and woodland.
Despite being hilly, the region receives a good amount of sunlight making it suitable for solar PV installations. However, due to its designation as an area of outstanding natural beauty (AONB), there may be restrictions on large-scale developments.
For large-scale solar PV farms, flat or gently sloping areas are most suitable as they allow for easier installation and maintenance while maximizing sun exposure. Areas outside the AONB but still close to Dunstable could be potential sites for such projects. These might include agricultural lands or brownfield sites where development would have less impact on the landscape.
Furthermore, industrial rooftops within Dunstable itself can also serve as potential locations for installing solar panels without affecting much of the surrounding topography or environment.
As always with such projects though it's important to conduct a detailed site survey considering factors like local weather patterns (especially average annual sunshine hours), grid connectivity options and environmental impact before deciding on specific locations.
It's also crucial to consult with local planning authorities given that UK planning policy encourages renewable energy while balancing this against other considerations like visual amenity and impacts on heritage assets or biodiversity.
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.
