Solar PV Analysis of Greenwich, United Kingdom
In Greenwich, England, United Kingdom (latitude 51.4781, longitude -0.0279), the average solar energy production per kW of installed solar capacity varies across the seasons. During summer, the daily average is 5.13 kWh per kW, while in winter it drops to 1.07 kWh per kW. Spring and autumn see averages of 4.36 kWh and 2.31 kWh per day per kW respectively.
Greenwich is located within the Northern Temperate Zone, which experiences seasonal weather changes that can impact solar power generation capabilities throughout the year. For instance, shorter daylight hours and increased cloud cover during winter months result in less available sunlight for solar energy production.
To optimize solar panel efficiency in this region, it is recommended to tilt panels at a fixed angle of 44 degrees South for maximum sunlight exposure throughout the year.
As a general observation, summers in Greenwich tend to be warm with abundant sunshine whereas winters are cold with frequent rain or snowfall periods that can reduce available sunlight for generating power via photovoltaic (PV) systems.
While there are no significant environmental or topographical factors impeding solar production at this location specifically mentioned here; local weather patterns such as fog or heavy cloud cover could potentially affect energy output on occasion.
When installing PV systems at this location it's important to take preventative measures like ensuring proper drainage around panels to prevent accumulation of debris or water that could obstruct sunlight access and regularly cleaning panels so they maintain optimal efficiency levels despite any potential weather-related challenges faced year-round
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.

Solar output per kW of installed solar PV by season in Greenwich
Seasonal solar PV output for Latitude: 51.4781, Longitude: -0.0279 (Greenwich, 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 Greenwich, United Kingdom
To maximize your solar PV system's energy output in Greenwich, United Kingdom (Lat/Long 51.4781, -0.0279) 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 Greenwich, 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 Greenwich, 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 Greenwich, 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 Greenwich, 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 Greenwich, United Kingdom
The topography around Greenwich, United Kingdom is generally flat. The area has a few hills to the east and south which would not be suitable for large-scale solar PV. However, there are some flat areas to the north and west of Greenwich that could be suitable for large-scale solar PV installations. These areas include Blackheath Common, Eltham Common, Shooters Hill, Plumstead Common and Charlton Park.
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.
