In simple terms, the location at Milford Haven in the United Kingdom is moderately suitable for generating energy using solar PV panels year-round. The amount of electricity that can be produced varies with each season, with summer and spring being the most productive times. Specifically, during summer you can expect around 5.84kWh per day for every kW of installed solar power, while in spring it's slightly less at about 5.04kWh/day. Autumn and winter see a significant drop in production to 2.21kWh/day and 1.05kWh/day respectively.
If you're installing fixed panel solar systems here, the best angle to tilt your panels for maximum yearly energy production is towards south at an angle of 43 degrees.
However, there are a few factors that could potentially reduce solar power generation in this area due to local weather conditions or environment-related issues:
- Weather: This region experiences frequent cloud cover and rain which can limit sunlight exposure on the panels.
- Seasonal Variation: As mentioned earlier, there's significant variation between seasons with less sun exposure during autumn and winter months leading to lower energy output.
To mitigate these challenges:
- Regular Maintenance: Keeping your panels clean from dust or other debris especially after heavy rain or storms will ensure they are working efficiently.
- Panel Type & Design: Using high-quality panels designed to perform well under various light conditions including cloudy weather could help increase efficiency.
- Battery Storage System: A battery storage system would allow excess energy generated during peak hours (like midday) or more productive seasons (like summer) to be stored for use when production is low.
Remember though that while these measures can help improve performance under challenging conditions they won't fully overcome limitations imposed by nature like lack of sunlight during certain periods of time or year.
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 Milford Haven
Seasonal solar PV output for Latitude: 51.719, Longitude: -4.9224 (Milford Haven, 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 43° South in Milford Haven, United Kingdom
To maximize your solar PV system's energy output in Milford Haven, United Kingdom (Lat/Long 51.719, -4.9224) throughout the year, you should tilt your panels at an angle of 43° 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 Milford Haven, 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 Milford Haven, United Kingdom. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 43° 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 Milford Haven, 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 Milford Haven, 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 Milford Haven, United Kingdom
Milford Haven is located in the southwestern part of Wales, United Kingdom. The topography of this area is characterized by its coastal location, with a mixture of flat and hilly terrains. It has a natural deep water harbour which makes it an important regional centre for maritime activities.
The flatter areas around Milford Haven would be most suitable for large-scale solar PV installations due to the ease of installation and maintenance. Also, these areas tend to have better sun exposure which increases the efficiency of solar panels.
Areas such as agricultural lands or industrial sites near Milford Haven could also be potential locations for large-scale solar PV projects because they often have less shading from trees or buildings compared to urban areas. However, any development will need to consider local planning regulations and environmental impact assessments.
In terms of weather conditions affecting solar energy production, Wales generally has less sunshine hours compared to other parts in the UK but still receives enough sunlight throughout the year that can make use of photovoltaic technology viable especially when combined with storage solutions or grid connections.
Please note that while geographic suitability is one factor in determining good locations for solar farms, there are many other factors including but not limited to: land ownership and usage rights; proximity to power grids; local climate conditions; local wildlife and biodiversity considerations; community support/opposition etc.
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.
