Thurles, Munster, Ireland, situated at coordinates 52.6849, -7.7995, presents a mixed picture for solar PV energy generation. Located in the Northern Temperate Zone, this site experiences significant seasonal variations in solar output, which impacts its overall suitability for year-round solar energy production.
Seasonal Solar Performance
The location demonstrates a stark contrast between summer and winter performance. During summer months, solar panels can generate a respectable 5.33kWh per day for each kW of installed capacity. Spring also shows promising results with 4.35kWh/day. However, autumn sees a significant drop to 2.04kWh/day, while winter performance plummets to a mere 0.96kWh/day.
These figures indicate that Thurles is most suitable for solar energy generation from late spring through early autumn. The extended daylight hours and generally clearer skies during this period contribute to higher energy yields. However, the substantial decrease in output during autumn and winter months presents challenges for consistent year-round energy production.
Optimal Panel Installation
To maximize year-round solar energy production at this location, fixed solar panels should be installed at a tilt angle of 44 degrees facing south. This angle has been calculated to optimize the capture of available sunlight throughout the year, taking into account the Earth's elliptical orbit and the site's specific latitude.
Environmental and Weather Considerations
Several factors could potentially impede solar production in Thurles. Ireland's climate is characterized by frequent cloud cover and rainfall, which can significantly reduce solar irradiance reaching the panels. Additionally, the region's northerly latitude results in shorter winter days, further limiting solar potential during colder months.
To mitigate these challenges, several preventative measures can be implemented:
- Use high-efficiency solar panels designed to perform well in low-light conditions
- Install a robust cleaning system to combat the effects of frequent rainfall and potential debris accumulation
- Consider incorporating energy storage solutions to balance out seasonal variations in production
While Thurles may not be ideal for year-round solar energy production, strategic installation and appropriate technology choices can still make solar PV a viable part of the local energy mix, particularly during the more productive months of the 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 104 locations across Ireland. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

Ideally tilt fixed solar panels 44° South in Thurles, Ireland
To maximize your solar PV system's energy output in Thurles, Ireland (Lat/Long 52.6849, -7.7995) 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 Thurles, Ireland
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 Thurles, Ireland. 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 |
|---|---|---|---|
| 36° South in Summer | 56° South in Autumn | 66° South in Winter | 44° 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 Thurles, Ireland
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 Thurles, Ireland.
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 Thurles, Ireland
The topography surrounding Thurles, Ireland, is characterized by gently rolling hills and fertile lowlands. Located in County Tipperary, this area is part of the broader Golden Vale region, known for its rich agricultural land. The landscape is a patchwork of green fields, divided by hedgerows and stone walls, with scattered farmsteads and small woodlands dotting the countryside. The River Suir meanders through the area, carving a shallow valley and contributing to the region's lush appearance. To the east and southeast of Thurles, the terrain gradually rises towards the Slieveardagh Hills, while to the west, the land remains relatively flat as it stretches towards the Silvermine Mountains in the distance.
Potential for Solar PV Development
When considering areas near Thurles for large-scale solar PV installations, several factors come into play. The gently undulating terrain offers some advantages for solar energy development, as it provides opportunities for optimal panel orientation without significant earthworks. The most suitable locations for solar farms would likely be found in the flatter areas to the west and southwest of Thurles. These regions benefit from fewer obstructions to sunlight and larger, contiguous parcels of land that could accommodate extensive arrays of solar panels. The agricultural nature of the land means that there are already many open fields that could potentially be repurposed for solar energy production. However, it's important to note that the region's high agricultural value may present challenges in terms of land-use competition. Any large-scale solar development would need to carefully balance energy production goals with the preservation of prime farmland. Areas to the north and northeast of Thurles, where the terrain becomes slightly more elevated, might also offer good potential for solar PV installations. These higher grounds could benefit from increased exposure to sunlight throughout the day, potentially improving the efficiency of solar panels. While the climate in Ireland is generally not considered ideal for solar energy due to its frequent cloud cover and rainfall, advances in solar technology have made it increasingly viable. The long summer days in this latitude can partially compensate for the reduced sunlight during winter months. Any development of large-scale solar PV in the Thurles area would require careful site selection, taking into account not only the topography but also proximity to electrical infrastructure, environmental considerations, and local planning regulations. The visual impact on the picturesque Irish countryside would also need to be carefully managed to maintain the region's aesthetic appeal.Ireland solar PV Stats as a country
