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

The location in Chelmsford, England, United Kingdom, is moderately suitable for generating solar energy throughout the year. The amount of electricity that can be produced from solar panels changes with the seasons due to variations in sunlight intensity and duration. In simple terms, during summer and spring, when the days are longer and sunnier, more electricity can be produced - specifically 5.13 kilowatt-hours (kWh) per day in summer and 4.41 kWh/day in spring per kilowatt (kW) of installed solar power.

However, during autumn and winter when days are shorter and there is less sunlight because of cloud cover or foggy conditions typical for UK winters, less electricity will be generated - about 2.29 kWh/day in autumn and only around 1.03 kWh/day in winter per kW of installed solar power.

For a fixed panel installation at this location to produce maximum possible energy throughout the year, it should ideally be tilted at an angle facing 44 degrees South.

In terms of local factors that could affect solar production at this location: Chelmsford experiences quite a bit of cloud cover throughout much of the year which might reduce efficiency; also potential shading from buildings or trees could obstruct sunlight reaching panels if not properly positioned; finally snowfall during winter months might cover panels reducing their effectiveness temporarily.

To ensure greater energy production despite these factors:

- Panels can be placed on rooftops or high grounds to avoid shading.
- Regular maintenance should include cleaning off any snow or debris that may accumulate on the panels.
- Using high-efficiency PV modules that perform better under low light conditions might help improve performance during cloudy days.

Remember though these measures would only mitigate but not entirely eliminate impacts from local environmental conditions affecting panel 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 754 locations across United Kingdom. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

Spring
Average 4.41kWh/day in Spring.

 

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

To maximize your solar PV system's energy output in Chelmsford, United Kingdom (Lat/Long 51.7219, 0.4811) 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: 51.7219, Longitude: 0.4811, the ideal angle to tilt panels is 44° South

Seasonally adjusted solar panel tilt angles for Chelmsford, 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 Chelmsford, 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

Assuming you can modify the tilt angle of your solar PV panels throughout the year, you can optimize your solar generation in Chelmsford, 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 44° angle facing South to capture the most solar energy in Chelmsford, 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 Chelmsford, 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 Chelmsford, 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.

Topography for solar PV around Chelmsford, United Kingdom

Chelmsford is located in the East of England, and it's largely flat with some rolling hills. The area is primarily urban but there are also rural areas with fields and farmland surrounding the city. The River Chelmer runs through the city, creating some valleys and wetland areas.

For large-scale solar PV installations, open, flat areas are usually most suitable as they allow for maximum sun exposure and easy installation. Therefore, the rural farmlands around Chelmsford could potentially be good locations for such projects. However, this would depend on specific site evaluations considering factors like soil type, land ownership, proximity to power grids and potential environmental impacts.

Additionally, solar panels can also be installed on large building rooftops in urban areas. So industrial zones or commercial districts within Chelmsford could also be viable locations for smaller-scale solar PV systems.

However any plan should consider local planning regulations and community sentiment towards renewable energy projects as these can significantly influence project feasibility.

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.
