Best Orientation For Solar Panels Ireland

Your solar panel orientation is very important when it comes to maximising the amount of electricity that your solar panels will produce.

Best orientation for solar panels ireland.

To get the best out of your photovoltaic panels you need to angle them towards the sun. Usually this is the best direction because solar panels will receive direct light throughout the day. In the northern hemisphere the general rule for solar panel placement is solar panels should face true south and in the southern true north. Do solar panels work in ireland.

Solar panels have a quick payback are free of running costs and will greatly reduce your homes energy bills. Solar panels are the most common and affordable form of alternative energy available in ireland. 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. 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.

The following table gives the best dates on which to adjust. However there is a difference between magnetic south and true south that must be considered. The angle and orientation of your roof is a significant factor when considering installing solar panels. How much will your roof direction affect the output of your solar panels.

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. Even seai state that tube panels will far outperform flat panels. Not using all the excess energy generated during the day will go back to the grid which may not be beneficial for you. Yes solar pv systems will still generate electricity when there is daylight so they will still function on overcast days in ireland.

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. 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. Solar power in ireland utilizes the power from pv solar panels in conjunction with the electric battery or water heating storage to store any extra energy generated for use in non day light hours. If your latitude is between 25 and 50 then the best tilt angle for summer is the latitude times 0 93 minus 21 degrees.

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. For the best results solar panels should be oriented towards the south. This is because the sun is always in the southern half of the sky in the northern hemisphere. This depends on both the direction of your roof and the pitch of the roof.
