At however many mega degrees our sun is; you would think someone would have done this way, way back.
I bought the cansolair ra240 last march 05 but when I took the protective paper off the lense one of the cans was askew.
I called the cansolair owner-inventor guy up in New Foundland and his concern was great and he acted responsibly and effectively. Wild accents up there in Newfieland! I did return it to the warehouse got a replacement, installed it and have had some fine results ever since.
He explained that they had just received an order for 2500 units which overwhelmed the small local factory and so the error was due to a demand he had never seen, I understand. They had only sold several hundred during the past few years.
I hope to see more of these in use. I notice the times I do not have to heat now and the oil guy has been just driving by without stopping. They estimate some reasonable savings which I am not likley to dispute it seems to me. Other than condensation forming blowing an initial moisture content when it first fires up I have no concerns about the longevity or effectivness of this panel. The moisture might be a bonus in these drier months, I am just a bit concerned as to the materials being ill effected by it on the insides over some period of years.
It also worked as a dehumidifier at certain times during the summer although when it got really hot I covered the face with a foil pad to keep it from baking. It heats considerably at either end of the season here in the hills of north central Ma and when the snows reflection is present it amplifies the time on quite a bit in fact. I chose this over the flat panel because I wanted to support a small company and also the convexed shape looked like it would catch more rays. I thus far feel it was a wise investment and would recomend it indeed.
