Ballinasloe, Connacht, Ireland, situated at latitude 53.3288 and longitude -8.2151, presents a mixed picture for solar PV energy generation. Located in the Northern Temperate Zone, this town experiences significant seasonal variations in solar energy production throughout the year.

Seasonal Solar Energy Output

The solar energy output in Ballinasloe varies considerably across the four meteorological seasons. Summer stands out as the most productive period, with an average daily output of 4.95 kWh per kW of installed solar capacity. Spring follows closely behind, generating 4.35 kWh/day. However, the output drops significantly during autumn, producing only 1.92 kWh/day, and plummets to a mere 0.96 kWh/day in winter.

Optimal Times for Solar Generation

Given these figures, the ideal times for solar energy generation in Ballinasloe are clearly the summer months, followed by spring. During these seasons, longer daylight hours and higher sun angles contribute to increased solar panel efficiency. The period from late March to early September is likely to yield the best results for solar PV systems in this location.

Panel Tilt Angle for Maximum Efficiency

To maximize year-round solar energy production in Ballinasloe, Connacht, fixed solar panels should be installed at a tilt angle of 45 degrees facing south. This angle has been calculated to optimize the panels' exposure to sunlight throughout the year, taking into account the location's latitude and the Earth's elliptical orbit.

Environmental and Weather Factors

Several factors could potentially impede solar production in Ballinasloe:

1. Cloud cover: Ireland is known for its frequent overcast conditions, which can significantly reduce solar panel efficiency.
2. Rainfall: Ballinasloe experiences considerable rainfall throughout the year, which can affect solar panel performance.

To mitigate these challenges, consider implementing the following preventative measures:

• Use high-efficiency solar panels designed to perform well in low-light conditions.
• Install a robust cleaning system to keep panels free from rain residue and debris.
• Implement microinverters or power optimizers to minimize the impact of partial shading on overall system performance.

While Ballinasloe's location presents some challenges for solar PV energy generation, particularly during autumn and winter, the strong performance during spring and summer months still makes it a viable option for renewable energy production. With proper planning and the right equipment, a solar PV system can contribute significantly to the area's energy needs, especially during the brighter half of the year.

Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.

So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 104 locations across Ireland. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

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

Seasonal solar PV output for Latitude: 53.3288, Longitude: -8.2151 (Ballinasloe, 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 Ballinasloe, Ireland

To maximize your solar PV system's energy output in Ballinasloe, Ireland (Lat/Long 53.3288, -8.2151) 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 Ballinasloe, 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 Ballinasloe, 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	57° South in Autumn	67° 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 Ballinasloe, 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 Ballinasloe, 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 Ballinasloe, Ireland

The area surrounding Ballinasloe, Ireland, is characterized by a gently rolling landscape typical of the Irish Midlands. This region, located in eastern County Galway, features a mix of low-lying plains and subtle hills, creating a picturesque rural setting. The topography is generally flat to undulating, with elevations gradually increasing as you move away from the town center. The River Suck, a tributary of the River Shannon, meanders through the area, adding to the diverse landscape. Its floodplains contribute to the formation of wetlands and meadows in the vicinity. The surrounding countryside is predominantly composed of agricultural land, including pastures for grazing livestock and fields used for crop cultivation.

Potential for Solar PV Development

When considering areas near Ballinasloe for large-scale solar photovoltaic (PV) installations, several factors come into play. The most suitable locations would be those with minimal shading, good exposure to sunlight, and relatively flat terrain to reduce installation costs and maximize energy production. The gently sloping fields to the south and southwest of Ballinasloe could be particularly well-suited for solar PV development. These areas tend to have fewer obstructions and receive more direct sunlight throughout the day. Additionally, land that is currently used for low-intensity agriculture or is classified as marginal farmland might be ideal for solar installations, as it would have less impact on food production. It's important to note that while the topography around Ballinasloe is generally favorable for solar PV, other factors such as grid connectivity, local planning regulations, and environmental considerations would also need to be taken into account when identifying specific sites for large-scale solar projects. Consultation with local authorities and detailed site assessments would be necessary to determine the most appropriate locations for such developments.
