Solar PV Analysis of Llanrwst, United Kingdom
The location at Llanrwst, Wales, United Kingdom, is decent but not optimal for generating energy via solar PV year-round. During the summer and spring seasons, the amount of sunlight available for solar energy production is relatively high with 5.31kWh/day and 4.39kWh/day respectively per kW of installed solar. This means that these two seasons are the most ideal times of year to generate solar power at this location.
However, during autumn and winter, the sunlight availability drops significantly to 1.94kWh/day and 0.90kWh/day respectively per kW of installed solar which makes these seasons less ideal for generating solar power.
For a fixed panel installation at this location, it's best to tilt panels towards south at an angle of 45 degrees in order to maximize total year-round production from solar PV.
In terms of environmental or other local factors that could impede solar production at this location; Llanrwst experiences moderate rainfall throughout the year which could potentially reduce sunlight exposure on some days thereby affecting energy output from your panels. In addition, there may also be potential obstructions such as buildings or trees that could cast shadows on your panels thus reducing their efficiency.
Preventative measures include choosing a spot with minimal shadowing throughout the day for panel installation and considering use of tracking systems that follow sun's movement across sky thereby ensuring maximum exposure even on less sunny days. Regular cleaning and maintenance can also help ensure greater energy production by removing any dirt or debris that might accumulate on your panels over time blocking sunlight absorption.
Lastly if possible install a battery storage system so you can store excess power produced during sunny periods (especially in spring/summer) then use it during less productive periods (autumn/winter). This will help you maintain consistent supply even when conditions aren't conducive for generation.
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 Llanrwst
Seasonal solar PV output for Latitude: 53.0814, Longitude: -3.7777 (Llanrwst, 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 45° South in Llanrwst, United Kingdom
To maximize your solar PV system's energy output in Llanrwst, United Kingdom (Lat/Long 53.0814, -3.7777) throughout the year, you should tilt your panels at an angle of 45° 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 Llanrwst, 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 Llanrwst, United Kingdom. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 45° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 37° South in Summer | 56° South in Autumn | 66° South in Winter | 45° 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 Llanrwst, 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 Llanrwst, 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 Llanrwst, United Kingdom
Llanrwst is located in the Conwy Valley in Northern Wales, United Kingdom. The topography of the area is characterized by a combination of flatlands along the valley bottom and hilly terrain on either side. It's surrounded by lush greenery with the Snowdonia National Park to its west.
For large-scale solar PV installations, flat or gently sloping lands are generally preferred as they allow for easier installation and maintenance, as well as optimal sun exposure. Therefore, the flatlands along the Conwy Valley would be more suitable for such projects.
However, it's important to consider other factors like local weather patterns (solar irradiance), land use restrictions and environmental impact before setting up a large-scale solar PV project. In particular, North Wales tends to have relatively high rainfall which could limit solar potential.
Also worth noting that areas within or near Snowdonia National Park may be protected under conservation laws that restrict such developments. Therefore, feasibility studies and consultations with local authorities would be necessary to identify specific suitable sites around Llanrwst for large scale solar PV installations.
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.
