Solar Energy Potential in Shannon, Munster, Ireland

Shannon, Munster, Ireland, located in the Northern Temperate Zone, presents a moderate potential for solar energy generation throughout the year. The seasonal variations in solar output are significant, with summer offering the highest production and winter the lowest. During summer, Shannon experiences peak solar energy generation, with an average daily output of 5.11 kWh per kW of installed solar capacity. This makes it the ideal season for solar power production in the region. Spring follows closely behind, with a daily average of 4.42 kWh/kW, providing excellent solar energy potential as daylight hours increase and weather conditions improve. Autumn sees a considerable decrease in solar output, with an average of 2.06 kWh/kW per day. This decline is due to shorter days and increased cloud cover typical of the season. Winter presents the most challenging period for solar energy generation in Shannon, Munster, with a daily average of only 1.04 kWh/kW. The low sun angle, shorter daylight hours, and frequent overcast conditions contribute to this reduced output.

Optimal Panel Installation

For fixed panel installations in Shannon, Munster, the ideal tilt angle to maximize year-round solar production is 45 degrees facing south. This angle helps optimize energy capture throughout the year, balancing the varying sun angles across seasons.

Environmental and Weather Factors

Several factors can impact solar energy production in Shannon: 1. Cloud cover: Ireland's climate is known for frequent cloud cover, which can significantly reduce solar panel efficiency. To mitigate this, high-efficiency panels designed for diffuse light conditions should be considered. 2. Rainfall: Shannon experiences considerable rainfall throughout the year. While rain can help keep panels clean, it also means fewer clear sky days. Installing panels with anti-reflective coatings can help maximize light absorption even in overcast conditions. 3. Wind: The region can experience strong winds, particularly during Atlantic storms. Ensuring robust mounting systems and regular structural inspections can prevent damage and maintain optimal panel positioning. 4. Temperature: Although Shannon's climate is generally mild, occasional temperature fluctuations can affect panel efficiency. Choosing panels with good temperature coefficients and ensuring proper ventilation can help maintain performance across various weather conditions. By taking these factors into account and implementing appropriate preventative measures, solar installations in Shannon can achieve better energy production despite the challenging environmental conditions.

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 Shannon

Seasonal solar PV output for Latitude: 52.6974, Longitude: -8.8635 (Shannon, 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 45° South in Shannon, Ireland

To maximize your solar PV system's energy output in Shannon, Ireland (Lat/Long 52.6974, -8.8635) 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 Shannon, 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 Shannon, Ireland. 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
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 Shannon, 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 Shannon, Ireland.

Our calculation method

1. Solar Position:
   We determine the Sun's position on the Winter solstice using the location's latitude and solar declination.
2. Shadow Projection:
   We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle.
3. 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 Shannon, Ireland

The topography around Shannon, Ireland, located at latitude 52.6974 and longitude -8.8635, is characterized by a mix of low-lying plains and gently rolling hills. This area is part of the Shannon Basin, a vast lowland region that surrounds the Shannon River, Ireland's longest waterway. The landscape is predominantly flat to slightly undulating, with elevations generally ranging from sea level to about 30 meters above sea level. The immediate vicinity of Shannon is dominated by the Shannon Estuary, where the river meets the Atlantic Ocean. This estuarine environment creates a unique coastal topography, with mudflats, salt marshes, and small islands dotting the waterway. Moving inland, the terrain gradually rises, forming subtle hills and shallow valleys. To the north and east of Shannon, the land becomes more varied, with occasional drumlin fields - small, elongated hills formed by glacial activity during the last ice age. These drumlins add texture to an otherwise relatively flat landscape, creating a patchwork of low rises and shallow depressions.

Suitability for Large-Scale Solar PV

When considering areas nearby that would be most suited to large-scale solar photovoltaic (PV) installations, several factors come into play. The ideal locations would combine favorable topography with minimal environmental and social impacts. The flat to gently sloping areas surrounding Shannon offer promising potential for solar PV development. These areas provide the necessary space and stable ground conditions for large arrays of solar panels. The open farmland to the east and southeast of Shannon, particularly in parts of County Limerick, could be well-suited for such projects. However, it's important to note that while the topography is generally favorable, other factors such as land use, grid connectivity, and local planning regulations would also play crucial roles in determining the most suitable sites. Additionally, care would need to be taken to avoid areas of ecological importance, such as wetlands near the Shannon Estuary or any protected natural habitats. The slightly elevated areas to the north and northeast, where the land begins to rise, might offer particularly good sites for solar PV. These locations could potentially benefit from slightly higher levels of solar radiation due to reduced shadowing effects and better exposure to the sun's path across the sky. In conclusion, while the topography around Shannon is generally conducive to solar PV development, a detailed site-specific analysis would be necessary to identify the most optimal locations, taking into account not just the physical landscape but also environmental, social, and infrastructural considerations.
