Dr. Ciaran Byrne:

There is another perspective, one that Mr. O'Mahony mentioned. To use a phrase, it is "solar bling". I do not mean this is a pejorative sense. One of our concerns is that, while we know the importance of retrofitting and improving the fabric of the home, we also know that people have a limited amount of funds to do that. There is another phrase – "You can only spend your money once". If the homeowner puts money into solar, will it impact negatively on his or her ability to insulate the fabric of the home?
