The two systems have different strengths and weaknesses. Ireland certainly has a greater abundance of wind than sunshine
One of the biggest barriers to people having their home or business fitted with renewable energy generating systems is the high upfront cost. And in this area solar PV comes out well ahead for a number of reasons.
There are a wide range of government support and subsidies available for the installation of solar panels. SEAI grants for homes and businesses, the TAMS3 scheme for farm installations. That’s not taking into account the 0% VAT rate for domestic solar PV systems. In contrast, there are currently no grant subsidies available for domestic wind turbines.
Positioning is also a factor. While small domestic wind turbines in the 400W range can be attached to a roof or chimney, if you want anything larger it’s likely going to have to go on the ground.
Then it will need to be positioned in a clear elevated location, away from any obstructions, such as your house. This means additional work wiring it into your home electrical grid. In contrast, the majority of small scale solar PV systems tend to be installed on the roofs of houses or businesses, with ground mounted arrays generally reserved for larger solar farms. Roof mounted systems are simple to wire up to your property.
Wind turbines, with their multiple moving parts, are also a higher maintenance option than solar PV, and will run up additional costs ensuring that they operate at maximum efficiency.
Overall, while wind energy is not pointless, for small scale production solar PV is more dependable and cheaper for homeowners and businesses in the majority of instances.
