Loughrea, Connacht, Ireland, situated at latitude 53.1942 and longitude -8.5688, presents a moderate potential for solar energy generation through photovoltaic (PV) systems. This location in the Northern Temperate Zone experiences significant seasonal variations in solar output, which impacts the overall efficiency of solar installations.

Seasonal Solar Performance

The solar energy production in Loughrea follows a predictable pattern aligned with the changing seasons. Summer months offer the highest yield, with an average daily output of 4.89 kWh per kW of installed solar capacity. Spring follows closely behind, producing 4.28 kWh/day. However, autumn sees a substantial drop to 1.86 kWh/day, while winter experiences the lowest output at just 0.92 kWh/day per kW installed.

These figures indicate that solar energy generation is most effective from late spring through early autumn. During this period, longer daylight hours and generally clearer skies contribute to increased solar radiation reaching the panels.

Optimizing Panel Installation

To maximize year-round solar production in Loughrea, Connacht, fixed panels should be installed at a tilt angle of 45 degrees facing south. This orientation helps capture the most sunlight throughout the year, balancing the lower sun angle in winter with the higher summer sun.

Environmental and Weather Considerations

Several factors can impact solar production in Loughrea: 1. Cloud cover: Ireland's climate is known for frequent overcast conditions, which can significantly reduce solar output. 2. Rainfall: The region experiences considerable precipitation, which can temporarily decrease panel efficiency.

To mitigate these challenges, consider the following measures: 1. Use high-efficiency panels designed for diffuse light conditions. 2. Implement a robust cleaning schedule to remove rain residue and maximize light absorption. 3. Install a monitoring system to track performance and quickly identify any issues.

While Loughrea's location is not ideal for year-round solar production, strategic installation and maintenance can still yield substantial benefits, particularly during the more productive months. The significant seasonal variations underscore the importance of complementing solar PV with other energy sources or storage solutions for consistent year-round power supply.

Solar output per kW of installed solar PV by season in Loughrea

Seasonal solar PV output for Latitude: 53.1942, Longitude: -8.5688 (Loughrea, 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 Loughrea, Ireland

To maximize your solar PV system's energy output in Loughrea, Ireland (Lat/Long 53.1942, -8.5688) 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 Loughrea, 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 Loughrea, 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
37° South in Summer	56° South in Autumn	66° South in Winter	45° 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 Loughrea, 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 Loughrea, 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 Loughrea, Ireland

The topography around Loughrea, Ireland, is characterized by a diverse landscape that combines gentle rolling hills, flat plains, and low-lying areas. Situated in County Galway, Loughrea is nestled in the eastern part of the county, where the terrain transitions from the rugged west coast to the more subdued central lowlands of Ireland. The town of Loughrea itself sits on the northern shore of Lough Rea, a freshwater lake that gives the town its name. The lake is a prominent feature of the local landscape, covering an area of approximately 2.5 square kilometers. The land surrounding the lake is relatively flat, with a gradual rise in elevation as you move away from the water's edge. To the north and east of Loughrea, the terrain becomes more undulating, with a series of low hills and shallow valleys. These hills, while not particularly steep or high, provide a subtle contrast to the flatter areas near the lake. The countryside in this direction is predominantly rural, with a patchwork of fields, small woodlands, and scattered farmsteads. South and west of Loughrea, the landscape tends to be flatter, with expansive areas of open farmland. This region is part of the larger central plain of Ireland, known for its fertile soil and agricultural productivity. The terrain here is generally level, with only minor variations in elevation.

Areas Suitable for Large-Scale Solar PV

When considering locations for large-scale solar photovoltaic (PV) installations near Loughrea, several factors come into play. The most suitable areas would typically be: The flat, open farmland to the south and west of Loughrea presents the most promising opportunities for large-scale solar PV projects. These areas offer expansive, unobstructed spaces that receive good sunlight exposure throughout the day. The level terrain also simplifies construction and maintenance of solar arrays. Some of the gently sloping hillsides to the north and east of Loughrea could also be suitable, particularly those facing south or southwest. These locations may benefit from slightly increased solar radiation due to their orientation, although care would need to be taken to avoid areas with significant shadowing from nearby hills. It's important to note that while the topography around Loughrea offers potential for solar PV development, other factors such as grid connectivity, land ownership, and environmental considerations would also play crucial roles in determining the most appropriate sites. Additionally, given Ireland's climate, with its frequent cloud cover and relatively low solar radiation compared to more southern latitudes, careful planning and efficiency optimization would be essential for any large-scale solar project in this region.
