Macroom, Munster, Ireland, situated at latitude 51.9017 and longitude -8.9492, presents a mixed picture for solar PV energy generation throughout the year. Located in the Northern Temperate Zone, this area experiences significant seasonal variations in solar energy potential.
Seasonal Solar Performance
Summer stands out as the most productive season for solar energy in Macroom, Munster, with an average daily output of 5.61 kWh per kW of installed solar capacity. Spring follows closely behind, generating 4.69 kWh per day. However, the performance drops considerably during autumn and winter, with outputs of 2.21 kWh and 1.14 kWh per day, respectively.
These figures highlight the stark contrast between the warmer and colder months, with summer producing nearly five times more energy than winter. The extended daylight hours and generally clearer skies during summer contribute significantly to this increased productivity.
Optimal Panel Installation
To maximize year-round solar energy production in Macroom, Munster, fixed solar panels should be installed at a tilt angle of 44 degrees facing south. This angle has been calculated to optimize energy capture across all seasons, taking into account the Earth's elliptical orbit and the location's specific solar elevation angles.
Environmental and Weather Factors
Several factors can impact solar energy production in Macroom:
- Cloud cover: Ireland is known for its frequent cloudy weather, which can significantly reduce solar panel efficiency.
- Rainfall: Macroom experiences considerable rainfall throughout the year, which can affect panel performance and require regular cleaning.
- Short winter days: The limited daylight hours during winter months contribute to the low energy output during this season.
Preventative Measures
To mitigate these challenges and enhance solar energy production, consider the following measures:
- Use high-efficiency solar panels designed to perform well in low-light conditions.
- Install a robust mounting system to withstand strong winds and heavy rainfall.
- Implement an automated cleaning system or schedule regular manual cleaning to remove dirt and debris.
- Consider a hybrid system combining solar with other renewable energy sources to ensure consistent power supply year-round.
While Macroom's location presents some challenges for solar energy production, particularly during the colder months, proper installation techniques and preventative measures can help maximize the potential of solar PV systems in this area.
Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.

Solar output per kW of installed solar PV by season in Macroom
Seasonal solar PV output for Latitude: 51.9017, Longitude: -8.9492 (Macroom, 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 Macroom, Ireland
To maximize your solar PV system's energy output in Macroom, Ireland (Lat/Long 51.9017, -8.9492) 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 Macroom, 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 Macroom, 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 | 66° 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 Macroom, 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 Macroom, 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 Macroom, Ireland
The area surrounding Macroom, Ireland, located at latitude 51.9017 and longitude -8.9492, is characterized by a diverse and picturesque landscape typical of County Cork. The town itself is situated in a valley along the River Sullane, with gently rolling hills and low mountains forming the backdrop to the region. To the north and northwest of Macroom, the terrain becomes more rugged as it transitions into the Boggeragh Mountains. These mountains, while not particularly high by global standards, provide a striking contrast to the lower-lying areas around the town. The slopes are often covered in a patchwork of fields, forests, and open moorland, creating a visually appealing mosaic of colors and textures. South of Macroom, the landscape gradually becomes less hilly, with more expansive areas of relatively flat or gently undulating terrain. This area is dominated by agricultural land, interspersed with small woodlands and hedgerows that define field boundaries. The River Lee, which flows eastward towards Cork City, adds to the topographical variety of the region.
Potential for Large-Scale Solar PV
When considering areas near Macroom that might be suitable for large-scale solar photovoltaic (PV) installations, several factors come into play. The ideal locations would typically be relatively flat, open areas with good exposure to sunlight and minimal shading from nearby hills or forests. The lowland areas to the south and southeast of Macroom present the most promising opportunities for solar PV development. These regions offer more extensive tracts of level ground, which would simplify the installation process and maximize the efficiency of solar panels. The gentler terrain in this direction also means there's less likelihood of hills casting shadows over potential solar farms. However, it's important to note that while the topography in this area may be suitable, other factors such as land use, grid connectivity, and local planning regulations would also need to be considered. Additionally, given Ireland's northern latitude and frequently overcast weather, any large-scale solar PV project would need to be carefully planned to ensure optimal energy production despite these challenges. The hillier regions to the north and west of Macroom, while scenic, would generally be less suitable for large-scale solar installations due to their uneven terrain and potential for shading. These areas might be better suited for smaller, distributed solar projects or other forms of renewable energy such as wind power. In conclusion, while Macroom's surroundings offer a mix of topographical features, the flatter lands to the south provide the most promising locations for potential large-scale solar PV developments, subject to other necessary assessments and approvals.Ireland solar PV Stats as a country
