Solar PV Analysis of Limerick, Ireland
The location at Limerick, Munster, Ireland is moderately suitable for generating energy via solar photovoltaic (PV) systems year-round. It's not the most ideal location due to its position in the Northern Temperate Zone and variable weather conditions, but it can still produce a reasonable amount of electricity.
In terms of seasonal performance, summer and spring are the best times for solar generation at this location. During summer, you can expect around 5.11 kilowatt-hours (kWh) per day from each kilowatt (kW) of installed solar panels. In spring, this number drops slightly to approximately 4.42 kWh/day per kW.
Autumn sees a further drop in production with an average output of about 2.06 kWh/day per kW while winter has the lowest productivity with only about 1.04 kWh/day per kW generated on average.
To maximize total year-round production from your solar PV system in Limerick, Munster, it's recommended that fixed panel installations be tilted at an angle of 45 degrees facing South.
However, there are several factors that could impact solar production at this location:
1) Weather: Ireland is known for frequent cloud cover and rain which could reduce sunlight exposure on your panels.
2) Seasonal variations: As mentioned earlier, autumn and winter have significantly lower output compared to spring and summer due to shorter daylight hours during these seasons.
3) Local environment: Any large buildings or trees nearby could potentially cast shadows on your panels reducing their efficiency.
To overcome these challenges:
- Consider installing adjustable mounts so you can change the tilt angle according to season maximizing sunlight exposure throughout the year.
- Regularly clean your panels as dust or dirt accumulation along with bird droppings can affect their performance.
- If possible avoid shading by placing them away from tall structures or trees if any exist near your property.
- Depending upon local guidelines consider using microinverters or power optimizers. These devices can help to ensure that each individual panel operates at its maximum potential even if others are shaded or underperforming.
In conclusion, while Limerick, Munster, Ireland may not be the most ideal location for solar energy production due to its weather and seasonal variations, it is still possible to generate a reasonable amount of electricity with proper installation and maintenance of your solar PV system.
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 Limerick
Seasonal solar PV output for Latitude: 52.6669, Longitude: -8.6274 (Limerick, 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 Limerick, Ireland
To maximize your solar PV system's energy output in Limerick, Ireland (Lat/Long 52.6669, -8.6274) 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 Limerick, 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 Limerick, 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 Limerick, 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 Limerick, 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 Limerick, Ireland
Limerick, Ireland is located in the mid-western part of the country and is characterized by a mix of low-lying flat lands and rolling hills. The River Shannon, Ireland's longest river, runs through the city providing a significant water source. There are also several smaller rivers and streams in this region.
As for solar PV suitability, it would largely depend on specific factors such as sun exposure, land availability and local regulations. In general terms though:
1) Flat areas: Large scale solar PV installations require large tracts of relatively flat land to maximize sunlight exposure. The low-lying flat lands around Limerick could potentially be suitable for this.
2) Agricultural land: Some parts of Limerick are used for agricultural purposes. Depending on local regulations, these areas might be converted into solar farms without significantly impacting the landscape or local biodiversity.
3) Brownfield sites: These are previously developed sites that have been abandoned or underused. They can be found in urban areas around Limerick City where they could host rooftop solar installations or small ground-mounted systems.
However, it should also be noted that while Ireland does receive a reasonable amount of sunshine annually (particularly during summer months), its northern latitude means it has less potential for generating electricity from solar compared to countries closer to the equator.
For any potential site for large-scale Solar PV deployment detailed feasibility study including aspects like grid connectivity possibilities, environmental impact assessment etc., need to be conducted before finalizing the location.
Ireland solar PV Stats as a country
Ireland ranks 83rd in the world for cumulative solar PV capacity, with 136 total MW's of solar PV installed. Each year Ireland is generating 27 Watts from solar PV per capita (Ireland ranks 61st in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in Ireland?
Yes, there are a number of incentives available for businesses wanting to install solar energy in Ireland. The Sustainable Energy Authority of Ireland (SEAI) offers grants and other financial support for businesses that wish to install solar PV systems. Additionally, the government has introduced a Feed-in Tariff scheme which pays businesses for any excess electricity they generate from their solar panels. Finally, businesses may be eligible for tax relief on the cost of installing a solar system through the Accelerated Capital Allowance Scheme.
