Solar PV Analysis of Welling, United Kingdom
The location in Welling, England, United Kingdom is reasonably suitable for generating energy through solar photovoltaic (PV) panels year-round. However, the effectiveness varies significantly across different seasons.
In simple terms, solar PV panels convert sunlight into electricity. Therefore, the amount of sunlight they receive directly impacts how much electricity they can produce. At this location in Welling, England, during summer and spring when there are longer daylight hours and more intense sunlight, the panels can generate a decent amount of electricity - averaging around 5.13 kilowatt-hours (kWh) per day in summer and 4.41 kWh per day in spring for each kilowatt of installed solar capacity.
However, during autumn and winter when days are shorter and sunlight less intense due to the earth's tilt away from the sun, these figures drop considerably - to about 2.29 kWh/day in autumn and just over 1 kWh/day in winter.
To maximize overall yearly production from these solar PV systems at this location, it is recommended that fixed panel installations be tilted at an angle of 44 degrees facing southwards towards the equator where sun shines most intensely.
As for local factors that might affect solar production: being located within Northern Temperate Zone means Welling experiences significant seasonal variations with shorter daylight hours and lower sun intensity during winter months which may impede energy generation from solar PV systems compared to locations closer to equator.
Additionally weather conditions such as cloud cover or fog could also reduce sunlight availability hence affecting performance of these systems - UK does have a reputation for its cloudy weather after all!
To mitigate against some of these issues it would be advisable to ensure clear unobstructed access to sky i.e., no tall buildings or trees casting shadows on panels especially around midday when sun is highest; regular cleaning/maintenance to remove any dust or debris that may accumulate on panel surfaces; plus possibly considering use of tracking systems that adjust panel orientation to follow sun's position in the sky thereby maximizing sunlight capture throughout the day.
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 756 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 Welling
Seasonal solar PV output for Latitude: 51.462, Longitude: 0.1046 (Welling, 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 Welling, United Kingdom
To maximize your solar PV system's energy output in Welling, United Kingdom (Lat/Long 51.462, 0.1046) 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 Welling, 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 Welling, 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 Welling, 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 Welling, 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 Welling, United Kingdom
Welling, United Kingdom, is located in the London Borough of Bexley and is relatively flat. The area does not have significant hills or mountains that could obstruct sunlight. Therefore, it's generally suitable for solar PV installations.
However, to identify specific areas best suited for large-scale solar PV installations would require a more detailed study considering factors such as land use (agricultural fields, industrial areas), local planning regulations (preservation of green spaces, restrictions on land use), proximity to electrical grid connections and infrastructure etc.
Generally speaking though, non-residential rooftops such as those of large commercial buildings or warehouses can be ideal for solar panel installations due to their large surface area and minimal shading. Unused agricultural fields or brownfield sites may also be suitable if local planning laws permit this kind of development.
Please note that even though the UK doesn't receive as much sunshine as some other countries with substantial solar power generation like Spain or Australia, it still has enough sunlight to make solar power a viable renewable energy source.
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.
