    Does anyone have any experience with <SNIP> in roof solar panels?

    My plumber will be fitting the solar panels soon, 4 with a 500Ltr tank. They are included in the overall price for the plumbing and heating.

    I started looking for info on these panels and could not find much. Could someone give me hte heads up on them. Where are they made? How they compare to other in roof panels etc.

    The house is an ICF house which should mean a very small heating requirement.I have under floor heating throughout, approx 2,600 sq ft. With this in mind I was toying with the idea of using the solar panels to run the under floor heating. One thing that occurred to me though was that the solar panels are least efficient in winter, if they work at all. This is the time of year with the highest heat requirement. Would a boiler have to be used for the winter? Would the system then be pointless as the heating wouldn't be on during the summer?

    Mod Edit: No company names on thread please.

    PM sent with supplier details

    There are differing views on solar and space heating in Ireland, my opinion is that it doesn't make economic sense because of the reasons that you outlined above. It makes perfect sense for domestic hot water production though provided the system is designed around the water requirement of the household.

    500 Litre cylinder and 4 flat plate panels is a big system for DHW for an average family but I assume in your case the 500Lt cylinder is meant to act as a store for your underfloor heating.. Having said that it's unlikely your central heating will get any energy in winter after your DHW requirement has been satisfied..
