Located in the province of Connacht, Mayo is one of the most picturesque counties in Ireland, with its rugged coastline reaching into the Atlantic Ocean.
As well as having a stunning landscape, Co. Mayo is known for its islands, an apparition of the Virgin Mary, and being apparently unable to break free of a 73 year old curse.
With a population of 137,231, it is one of Ireland’s largest counties by number of inhabitants, as well as land area. It is one of three counties which claim to have the longest coastline in Ireland along with Doneal and Cork.

Mayo Solar Panels Adoption
In the first half of 2024, there were 27 solar panel installations for every 10,000 people – showing the growing popularity of solar energy in the county.
The latest data shows that the SEAI has awarded a total of 1,528 PV grants in Mayo since 2015.
The recent growth is put into sharp focus when looking at 2024 data – more than a third of the 1,528 grants have been this year alone!
Mayo Climate
One of the most westerly counties in Ireland, Mayo’s climate is affected by the Atlantic Ocean and its mountain ranges.
Mayo Sunshine Hours
Mayo receives more than enough sunshine for your rooftop solar panels to save you hundreds of euro per year on energy bills (and more than €1,000 for some people).
Ireland gets a surprising amount of sunshine per year – and it’s more than you might think.
Mayo’s mountain ranges and warm air coming in from the Atlantic means that the county gets more cloudy days and rainfall than other regions such as the southeast – but only sunlight is needed for solar panels to generate electricity.
And while pure sunshine is great, PV panels work every day regardless!
Mayo Towns and Villages
Mayo has a number of well-known and sizable towns and villages. Among the more well known are Castlebar, Westport, Ballina, and Knock.

Mayo attracts thousands of tourists each year from far and near, to its cliffs along the Atlantic coastline, and islands such as Achill.
Mayo also has a relatively high level of religious tourism with Catholics flocking to Knock Shrine to see where the Virgin Mary is said to have appeared to locals in 1871.
There is also an annual pilgrimage up Croagh Patrick where some participants climb the 764 meter high mountain in their bare feet.
