Solar PV Analysis of Caher, Ireland
The location at Caher, Munster, Ireland, which is in the Northern Temperate Zone, can produce a decent amount of energy from solar power throughout the year. However, the effectiveness varies greatly by season.
In summer and spring, you can expect to generate a good amount of energy - 5.39 kilowatt hours per day in summer and 4.42 kilowatt hours per day in spring for every kilowatt of solar panel installed. This means that these seasons are ideal for generating solar power due to longer daylight hours and more intense sunlight.
On the other hand, autumn and winter see a significant drop in production with only 2.10 kWh/day in autumn and even lower at 1.01 kWh/day during winter due to shorter days and less intense sunlight.
For fixed panel installations at this location, it's best to tilt panels at an angle of 44 degrees facing southwards for maximum year-round production from your solar PV system.
As for environmental or local factors that could impede solar production at this location; there could be several potential issues:
1) Ireland is known for its cloudy weather which could reduce the efficiency of your solar panels as they rely on sunlight.
2) The region's topography might also affect how much sun exposure your panels get depending on where they're placed.
3) Lastly, if there are buildings or trees around that cast shadows on your panels then this will also reduce their productivity.
To overcome these issues:
1) You might want to consider using advanced photovoltaic cells designed specifically for low-light conditions.
2) If possible try installing your panels on high ground or rooftops where they'll get more sun exposure.
3) Trim any nearby trees or structures casting shadows over your installation site if possible.
In conclusion, while Caher isn't perfect all year round for generating solar energy due to its seasonal variations and potential environmental challenges; with proper planning it can still be a viable location for solar energy production.
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 Caher
Seasonal solar PV output for Latitude: 52.3774, Longitude: -7.9257 (Caher, 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 44° South in Caher, Ireland
To maximize your solar PV system's energy output in Caher, Ireland (Lat/Long 52.3774, -7.9257) throughout the year, you should tilt your panels at an angle of 44° 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 Caher, 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 Caher, Ireland. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 44° 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 Caher, 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 Caher, 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 Caher, Ireland
Caher, Ireland is located in the southwestern part of the country and is characterized by a mix of flatlands and rolling hills. The region experiences a temperate maritime climate with mild winters and cool summers.
The topography around Caher includes open fields, pastures, forests, and some hilly areas. The landscape is generally green with rich vegetation due to frequent rainfall. There are also several rivers running through this area.
When considering large-scale solar PV installations, it's essential to take into account factors such as sunlight availability, land use restrictions, proximity to power grids for transmission purposes, environmental impacts among others.
Given these factors:
1. Open fields: These could be suitable for large-scale solar PV installations due to their flat nature which allows for easy installation and maximum exposure to sunlight.
2. Pasture lands: If not used intensively for agriculture or livestock rearing, these could also be potential sites for solar farms.
3. Unused or degraded lands: These can be rehabilitated through solar farm projects which can have additional benefits such as soil conservation.
However specific feasibility studies would need to be conducted on potential sites taking into account local regulations regarding land use for energy production projects as well as detailed site assessments including sun path analysis (to determine how much sunlight a location receives throughout the year), soil type analysis (to assess suitability of ground-mounted systems), etc.
It's worth noting that while Ireland does receive lower levels of sunshine compared to countries closer to the equator, it still receives enough sun that combined with advancements in solar technology make Solar PV viable especially during summer months when daylight hours are long.
As always though any specific project should conduct its own detailed feasibility study taking into account all relevant factors including those mentioned above but also economic ones like cost of installation vs projected returns etc.
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.
