Caherdaniel, Munster, Ireland, situated on the southwestern coast of the country, offers moderate potential for solar PV energy generation throughout the year, with significant seasonal variations in production capabilities.
Seasonal Solar Production
The solar energy output at this location shows a clear pattern of seasonal fluctuation. During summer months, each kilowatt of installed solar capacity produces an impressive 5.24kWh per day. Spring follows as the second most productive season with 4.64kWh daily output per kilowatt installed. However, production drops significantly during autumn to 2.10kWh daily, and reaches its lowest point in winter with just 1.01kWh per day.
This pattern demonstrates that Caherdaniel's solar potential is heavily concentrated in the warmer months, with approximately 75% of annual production occurring during spring and summer. The six-month period from March through August represents the ideal time for solar energy generation at this location.
Optimal Installation Angle
For fixed panel installations in Caherdaniel, Munster, the ideal tilt angle to maximize year-round solar production is 44 degrees facing South. This specific angle has been calculated to optimize energy capture across all seasons based on the location's latitude and solar elevation patterns.
Environmental and Weather Challenges
Several significant factors may impede solar production at this coastal location:
- Marine salt spray can accumulate on panels, creating a film that reduces efficiency and potentially causes corrosion
- Frequent Atlantic weather systems bring cloud cover and precipitation
- Winter storms with high winds pose risks to panel installations
- Morning coastal fog, especially in summer months, can delay peak production hours
Mitigation Strategies
To address these challenges, several preventative measures are recommended during installation:
- Use marine-grade components and salt-resistant panel coatings
- Install robust mounting systems rated for coastal wind conditions
- Implement automated cleaning systems or schedule regular manual cleaning to remove salt deposits
- Consider micro-inverters or power optimizers to minimize production losses from partial shading
- Position arrays with sufficient elevation to avoid ground-level morning fog where possible
While Caherdaniel's location presents some challenges for solar energy production, particularly during winter months, proper system design and installation practices can help maximize the energy harvested during the productive spring and summer seasons.

Solar output per kW of installed solar PV by season in Caherdaniel
Seasonal solar PV output for Latitude: 51.7664, Longitude: -10.0936 (Caherdaniel, Ireland), 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 44° South in Caherdaniel, Ireland
To maximize your solar PV system's energy output in Caherdaniel, Ireland (Lat/Long 51.7664, -10.0936) 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 Caherdaniel, 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 Caherdaniel, 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 | 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 Caherdaniel, 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 Caherdaniel, 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 Caherdaniel, Ireland
The landscape around Caherdaniel, located on the southwestern coast of Ireland in County Kerry, features a dramatic and varied topography characteristic of Ireland's Atlantic coastline. This area sits on the renowned Ring of Kerry tourist route and forms part of the Iveragh Peninsula, offering a diverse terrain that transitions from rugged coastline to rolling hills and mountains.
Coastal Features
Caherdaniel overlooks the sheltered waters of Derrynane Bay, with the coastline characterized by a series of small coves, beaches, and rocky outcrops. The Atlantic Ocean has shaped this shoreline over millennia, creating a jagged perimeter with numerous inlets. Just offshore lie several small islands, including Deenish and Scariff Islands, which contribute to the area's picturesque maritime setting.Inland Topography
Moving inland from the coast, the terrain rises gradually through undulating hills covered with a patchwork of agricultural fields, heathland, and patches of woodland. This transitional landscape gives way to more substantial elevation changes as one approaches the central spine of the Iveragh Peninsula. The most significant topographical feature near Caherdaniel is the presence of the Macgillycuddy's Reeks mountain range, which dominates the northeastern horizon. While the highest peaks of this range (including Carrauntoohil, Ireland's tallest mountain) are some distance away, their foothills extend toward the Caherdaniel area, creating a backdrop of significant elevation.Valleys and Water Features
The topography is dissected by several river valleys that drain the upland areas, creating sheltered corridors of flatter land. These valleys often contain small streams and rivers that flow toward the Atlantic. The area also features scattered small lakes, particularly in the higher elevation zones to the north and east.Suitability for Solar PV Development
When considering locations for large-scale solar PV development near Caherdaniel, several factors related to the topography must be evaluated:South-Facing Slopes
The most promising areas for solar PV installation would be the gently sloping, south-facing hillsides that can be found in the transitional zones between the coastal plains and the higher mountains. These locations benefit from good solar exposure throughout the day and reduced shadowing effects from adjacent terrain.Lower Elevation Plateaus
Several relatively flat plateaus at moderate elevations inland from Caherdaniel offer potential for solar development. These areas typically have fewer constraints from steep slopes while still maintaining good solar access. The land between Caherdaniel and Waterville, for example, includes sections of more level terrain that could accommodate larger installations.Agricultural Transition Zones
The boundary areas where agricultural land meets rougher upland terrain often present opportunities for solar development. These locations frequently have lower agricultural productivity while offering reasonable access to existing infrastructure. Several such zones can be found in the broader Iveragh Peninsula, particularly moving east from Caherdaniel.Topographical Challenges
It's important to note that the mountainous nature of much of the surrounding region does present challenges for large-scale solar development. The numerous steep slopes, particularly in the northern and eastern directions, would make construction and maintenance difficult while potentially creating shadowing issues during parts of the day. Additionally, the coastal areas, while flat, are often subject to strong Atlantic winds and salt spray, which can impact solar equipment durability. The most sheltered valleys, while protected from these elements, may receive reduced direct sunlight due to shadowing from surrounding hills. The complex topography also means that careful site-specific assessment would be necessary, as solar radiation can vary significantly even over short distances in such varied terrain. Microclimate effects created by the mountains and coast further complicate the selection of optimal sites.Ireland solar PV Stats as a country
