Solar panels are the most common and affordable form of alternative energy available in ireland.
Best orientation for solar panels ireland.
How much will your roof direction affect the output of your solar panels.
While the angle of your solar panels is important a more important factor in your energy production is going to be the direction your panels face.
To get the best out of your photovoltaic panels you need to angle them towards the sun.
Get the latest and best technology for your investment.
For example a solar panel placed flat onto a west facing wall will produce about half the amount of electricity compared to being placed at a 30 degree angle on a south facing roof.
This depends on both the direction of your roof and the pitch of the roof.
However there is a difference between magnetic south and true south that must be considered.
The following table gives the best dates on which to adjust.
Usually this is the best direction because solar panels will receive direct light throughout the day.
Not using all the excess energy generated during the day will go back to the grid which may not be beneficial for you.
Do solar panels work in ireland.
Solar panels installed on a roof facing southwest or southeast will generally produce about 8 less power than the same panels in the same climate on a south facing roof.
This is because the sun is always in the southern half of the sky in the northern hemisphere.
Yes solar pv systems will still generate electricity when there is daylight so they will still function on overcast days in ireland.
The optimum angle varies throughout the year depending on the seasons and your location and this calculator shows the difference in sun height on a month by month basis.
As we re in the northern hemisphere the best solar panel orientation is obviously south but.
The angle and orientation of your roof is a significant factor when considering installing solar panels.
For the best results solar panels should be oriented towards the south.
What happens if your roof isn t facing south.
If your latitude is between 25 and 50 then the best tilt angle for summer is the latitude times 0 93 minus 21 degrees.
Even seai state that tube panels will far outperform flat panels.
In these conditions they will not be able to produce power at their maximum rated capacity the figure in kilowatts kw rather at some fraction of this figure.
If you are going to adjust the tilt of your solar panels twice a year and you want to get the most energy over the whole year then this section is for you.
Your solar panel orientation is very important when it comes to maximising the amount of electricity that your solar panels will produce.
