Carrigaline, Munster, Ireland, located at 51.814° N latitude and -8.3964° E longitude, presents a moderate potential for solar energy generation throughout the year. This location in the Northern Temperate Zone experiences significant seasonal variations in solar output, which affects the overall efficiency of photovoltaic (PV) systems.
Seasonal Solar Output
The solar energy production in Carrigaline varies considerably across the four meteorological seasons. Summer yields the highest output at 5.55 kWh per day for each kilowatt of installed solar capacity. Spring follows with 4.62 kWh/day, while autumn sees a significant drop to 2.14 kWh/day. Winter experiences the lowest production at just 1.09 kWh/day per kW installed.
These figures indicate that solar energy generation is most effective during the longer, sunnier days of summer and spring. The substantial decrease in autumn and winter output is due to shorter daylight hours and increased cloud cover typical of Ireland's climate.
Optimal Panel Installation
To maximize year-round solar energy production in Carrigaline, Munster, fixed solar panels should be installed at a tilt angle of 44 degrees facing south. This angle optimizes the panels' exposure to sunlight throughout the year, balancing the seasonal variations in the sun's position.
Environmental and Weather Factors
Several factors can impact solar production in Carrigaline:
- Cloud cover: Ireland's climate is known for frequent overcast conditions, which can significantly reduce solar output.
- Rainfall: The region experiences considerable rainfall, which can temporarily decrease panel efficiency.
- Maritime climate: Proximity to the coast may lead to salt spray accumulation on panels, potentially affecting performance.
Preventative Measures
To mitigate these challenges and ensure optimal energy production, consider the following measures when installing solar PV systems in Carrigaline:
- Use high-efficiency panels designed for low-light conditions
- Install a robust cleaning system or schedule regular manual cleaning to remove salt deposits and other debris
- Implement micro-inverters or power optimizers to minimize the impact of partial shading
- Consider adding a battery storage system to maximize the use of generated energy during low-production periods
While Carrigaline's location presents some challenges for solar energy production, particularly during autumn and winter, proper system design and maintenance can still yield satisfactory results, especially during the more productive summer and spring months.
Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.

Ideally tilt fixed solar panels 44° South in Carrigaline, Ireland
To maximize your solar PV system's energy output in Carrigaline, Ireland (Lat/Long 51.814, -8.3964) 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 Carrigaline, 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 Carrigaline, 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 |
|---|---|---|---|
| 35° South in Summer | 56° 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 Carrigaline, 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 Carrigaline, 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 Carrigaline, Ireland
Carrigaline, located in County Cork, Ireland, sits in a picturesque landscape characterized by gently rolling hills and low-lying coastal areas. The town itself is nestled in a shallow valley, with the Owenabue River winding its way through the center before flowing into Cork Harbour to the east. The surrounding countryside is a patchwork of green fields, divided by hedgerows and stone walls, typical of rural Ireland. To the north and west, the land gradually rises, forming modest hills that provide panoramic views of the area. These hills, while not particularly steep or high, contribute to the varied topography of the region. To the south and east of Carrigaline, the terrain becomes flatter as it approaches the coastline. This area features a mix of agricultural land and wetlands, with some parts transitioning into mudflats and salt marshes near the shore of Cork Harbour.
Potential for Large-Scale Solar PV
When considering areas near Carrigaline for large-scale solar PV installations, several factors come into play. The gently sloping hills to the north and west of the town could potentially be suitable locations. These areas often receive good sun exposure and are less likely to be affected by coastal mists or fog that might occur closer to the harbour. The flatter agricultural lands to the south and east of Carrigaline might also be considered for solar PV projects. These areas typically have fewer obstructions that could cast shadows on solar panels, which is beneficial for maximizing energy production. However, it's important to note that the proximity to wetlands and the coast might introduce challenges related to environmental conservation and planning permissions. It's worth mentioning that while the topography around Carrigaline offers some potential for solar PV, Ireland's climate, characterized by frequent cloud cover and relatively low levels of direct sunlight compared to more southern latitudes, presents challenges for solar energy production. Any large-scale solar PV project in this area would need to carefully consider these factors, along with local zoning laws, grid connection possibilities, and community impact. Ultimately, detailed site surveys and environmental impact assessments would be necessary to determine the most suitable locations for large-scale solar PV installations in the vicinity of Carrigaline. These studies would take into account not just the topography, but also factors such as soil conditions, existing land use, proximity to electrical infrastructure, and potential ecological impacts.Ireland solar PV Stats as a country
