Solar PV Analysis of Tuam, Ireland
The location at Tuam, Connacht, Ireland is moderately suitable for generating energy via solar PV throughout the year. The highest amount of electricity output can be expected in summer and spring, with an average of 4.95kWh/day and 4.35kWh/day per kW of installed solar respectively. This means that these seasons are the best times to generate solar power because longer daylight hours and higher sun intensity result in more energy production.
On the other hand, autumn and winter see a significant drop in potential solar energy generation due to shorter days and lower sun intensity. In autumn, you can expect about 1.92kWh/day per kW of installed solar while winter drops even further to just 0.96 kWh/day per kW.
For a fixed panel installation at this location, tilting panels at an angle of 45 degrees South is recommended to maximize total year-round production from your solar PV system.
However, there could be environmental or weather factors that might affect your ability to generate sufficient power from your panels in Tuam, Connacht, Ireland - such as cloudy or rainy weather which is common here; this reduces sunlight exposure on your panels thereby reducing their efficiency.
To mitigate against these challenges:
1) Consider installing tracking systems so that your panels can follow the movement of the sun across the sky during daytime hours – maximizing their exposure to direct sunlight.
2) Regularly clean off any dirt or debris that may accumulate on your panels – this ensures they're working as efficiently as possible.
3) If feasible for you financially and logistically speaking: consider adding battery storage capacity into your setup – allowing you store excess power generated during peak periods (like sunny summer days), then use it later when conditions aren't as ideal (like overcast winter days).
In summary: While not perfect all year round due its geographical location & local climate conditions; with some smart planning & additional investment where possible - Tuam presents decent opportunities for effective solar energy generation.
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 Tuam
Seasonal solar PV output for Latitude: 53.5191, Longitude: -8.8491 (Tuam, 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 Tuam, Ireland
To maximize your solar PV system's energy output in Tuam, Ireland (Lat/Long 53.5191, -8.8491) 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 Tuam, 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 Tuam, 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 Tuam, 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 Tuam, 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 Tuam, Ireland
Tuam is located in the western part of Ireland, in County Galway. The topography around Tuam is relatively flat with low-lying areas and some gentle hills. The area is characterized by a mix of farmland, residential areas, and patches of woodland.
The climate in Tuam and the rest of Ireland is categorized as temperate maritime, which means it experiences mild temperatures but often has cloudy skies. This may limit the effectiveness of solar PV installations to some extent.
However, large-scale solar PV projects are not entirely dependent on high levels of sunlight; they can still operate efficiently under diffused light conditions. Therefore, the most suitable areas for large-scale solar PV near Tuam would be open spaces with minimal shading such as unused farmlands or industrial zones that have easy access to the grid infrastructure.
It's also worth noting that while Ireland doesn't get as much sun as more southern European countries do, it still gets enough to make solar power viable - especially given advancements in photovoltaic technology which allow efficient energy production even under less than ideal conditions.
As always though before any potential development could take place an appropriate site assessment would need to be conducted considering factors beyond just topography including local weather patterns and environmental impacts among others.
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.
