Solar PV Analysis of Chiswick, United Kingdom
Chiswick, England, United Kingdom, is a location that can produce decent amounts of solar energy throughout the year. However, it's not perfect due to its place in the Northern Temperate Zone and weather conditions.
In simpler terms, here's how much electricity you could expect a solar panel to generate each day for every kilowatt (kW) of solar power installed:
- In summer: about 5.13 kWh
- In autumn: around 2.31 kWh
- In winter: roughly 1.07 kWh
- In spring: approximately 4.36 kWh
The best times to generate solar at this location are during the summer and spring because these seasons provide more sunlight hours compared to autumn and winter.
If you're planning on installing fixed panels here, tilting them at an angle of 44 degrees facing south will help maximize your year-round production from your solar PV system.
As for environmental or local factors that might hinder your system's performance:
Firstly, Chiswick experiences significant seasonal variations in sunshine duration which affects the amount of energy generated by the panels especially during shorter days in winters.
Secondly, cloud cover also plays a role as it reduces sunlight exposure significantly affecting energy generation particularly during cloudy or overcast days which are quite common in UK’s weather pattern.
Lastly rainfall; while rain itself doesn’t impede production directly but frequent heavy downpours might lead to accumulation of dirt and debris on panels reducing their efficiency over time.
To overcome these issues:
1) Ensure regular maintenance checks especially after heavy rains or strong winds for any dirt accumulation & clean them as needed.
2) Consider using advanced systems with better low-light performance if budget allows.
3) Plan for additional storage capacity (like batteries) or backup power sources during periods when less energy is produced i.e., winters due to shorter daylight hours & increased cloud cover.
4) Lastly monitor your system regularly so that any issues can be detected and resolved quickly to ensure maximum efficiency.
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 Chiswick
Seasonal solar PV output for Latitude: 51.4936, Longitude: -0.2583 (Chiswick, 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 Chiswick, United Kingdom
To maximize your solar PV system's energy output in Chiswick, United Kingdom (Lat/Long 51.4936, -0.2583) 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 Chiswick, 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 Chiswick, 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 Chiswick, 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 Chiswick, 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 Chiswick, United Kingdom
Chiswick is located in the western part of London, United Kingdom. The topography of Chiswick and its surrounding areas is relatively flat as it's situated in the Thames Valley. There are some slight undulations due to river terraces but overall, it's largely a low-lying area.
The Thames Valley region does not have high mountains or hilly terrain that would obstruct sunlight, making it suitable for solar energy production. However, being an urbanized area with dense infrastructure and buildings may limit the availability of large open spaces required for largescale solar PV installations.
Potential locations for largescale solar PV around this area could be:
1. Unused industrial lands: These often have fewer restrictions on land use changes and can provide large enough spaces.
2. Rooftops: Large commercial buildings or warehouses typically have expansive rooftops which can accommodate significant numbers of solar panels.
3. Farmlands: Outside the urban core, there are agricultural lands which might be used for dual purpose - farming along with solar power generation if local regulations allow.
However, any decision on where to place these installations should take into account factors such as local planning laws and regulations, potential environmental impact assessments, grid connectivity options among others.
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.
