Solar PV Analysis of Malahide, Ireland
Malahide, Leinster, Ireland, situated at 53.454°N latitude and -6.1585°E longitude, presents a mixed picture for solar PV energy generation. Located in the Northern Temperate Zone, this coastal town experiences significant seasonal variations in solar energy production.
Seasonal Solar Output
Solar energy generation in Malahide peaks during the summer months, with an average daily output of 5.21 kWh per kW of installed solar capacity. Spring follows as the second most productive season, yielding 4.34 kWh/day. However, autumn sees a substantial drop to 2.07 kWh/day, while winter production plummets to a mere 0.96 kWh/day.
These figures highlight the stark contrast between summer and winter solar potential in Malahide. The long, relatively sunny days of summer provide excellent conditions for solar energy production. Conversely, the short, often overcast winter days significantly hamper solar output.
Optimal Panel Configuration
To maximize year-round solar energy production in Malahide, Leinster, fixed solar panels should be installed at a 45-degree angle facing south. This tilt angle optimizes the panels' exposure to sunlight throughout the year, balancing the low winter sun with the high summer sun.
Environmental and Weather Factors
Several factors can impede solar production in Malahide:
- Cloud cover: Ireland's climate is characterized by frequent cloud cover, which can significantly reduce solar irradiance.
- Rainfall: Malahide experiences considerable rainfall, which can affect panel efficiency and require more frequent cleaning.
- Coastal location: Proximity to the sea increases the risk of salt spray accumulation on panels, potentially reducing their effectiveness.
To mitigate these challenges, consider implementing the following measures:
- Use high-efficiency panels designed for diffuse light conditions
- Install a robust cleaning system or schedule regular manual cleaning
- Apply anti-corrosion coatings to protect against salt spray damage
- Implement microinverters or power optimizers to minimize the impact of partial shading
While Malahide's location presents some challenges for solar PV generation, proper system design and maintenance can still yield significant energy production, particularly during the spring and summer months.
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 Malahide
Seasonal solar PV output for Latitude: 53.454, Longitude: -6.1585 (Malahide, 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 Malahide, Ireland
To maximize your solar PV system's energy output in Malahide, Ireland (Lat/Long 53.454, -6.1585) 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 Malahide, 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 Malahide, 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 Malahide, 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 Malahide, 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 Malahide, Ireland
The topography around Malahide, Ireland, is characterized by a mix of gently rolling coastal plains and low-lying areas. Malahide itself is situated on the east coast of Ireland, along the Irish Sea. The terrain in this region is generally flat to slightly undulating, with elevations typically ranging from sea level to about 50 meters above sea level.
The immediate coastline features sandy beaches and some rocky outcrops. As you move inland, the landscape gradually rises, forming subtle hills and shallow valleys. The area is dotted with small streams and rivers that flow towards the sea, creating minor variations in the terrain. Much of the surrounding land is used for agriculture, with fields and pastures dominating the rural areas outside the town.
To the west and southwest of Malahide, the land becomes slightly more elevated, with gentle slopes leading towards the interior of County Dublin. However, there are no significant mountains or steep hills in the immediate vicinity.
Areas Suitable for Large-Scale Solar PV
When considering locations for large-scale solar photovoltaic (PV) installations near Malahide, several factors come into play. The most suitable areas would likely be found in the rural lands to the west and southwest of Malahide, where there are open spaces with minimal shading from trees or buildings. These areas offer the following advantages:
- Gently sloping terrain that can provide good sun exposure throughout the day
- Agricultural lands that may be available for solar farm development
- Relatively flat topography, which simplifies installation and reduces costs
- Proximity to existing electrical infrastructure for grid connection
However, it's important to note that while the topography in this region is generally favorable for solar PV, other factors such as local regulations, land availability, and environmental considerations would need to be carefully assessed before determining the most suitable locations for large-scale solar installations. Additionally, the relatively northern latitude of Malahide means that solar irradiance levels are lower compared to more southern locations, which could impact the overall efficiency and economic viability of large-scale solar projects in the area.
