QuoteThey've done me well but for the $440 why not buy a 200 watt panel? I bought 3 205 watt panels for $364ea a month ago.

No, no, no, that is not what I said. I said "They do not carry the UL or any other approval. That means they will not pass inspection". The fact that the panels are being sold as blemished has nothing to do with UL approval. UL doesn't care if they are pretty. Mostly UL tests for electrical and mechanical safety. Things like does the wire used have insulation that is rated for high enough temperatures, does the insulation have UV resistance, is the conductor large enough to carry the maximum expected amperage, can the module handle high voltages when series connected, and other stuff. Other brands of panels are also sold as blemished from time to time. I missed out on some Sharp panels by a few weeks when I was looking. They had some kind of scratches on the aluminum frames. They still carried the UL, CE, Tuv approvals. Some Sun panels are simply not approved. Period. Doesn't matter if they have a perfect or blemished finish. On some models they come right out and say yes or no on UL. On others one has to search and sometimes still can not determine if the label indicates UL approved or not.Maybe I worry too much. I wonder why the manufacturer has not had the panels tested and approved. Maybe there's nothing at all wrong with them. Maybe the panels are deficient in some way? I have no way of knowing. I see them as a long term investment and that's why I bought a "name brand". I'm not saying that the Sharp are better or that the Sun are crap. However, as with anything from soup to nuts I do wonder how two products similar in nature can vary so widely in price. What I do know is that I have bought many things over the years. Sometimes I have gone for the low ball price just because I don't like to spend a lot of money. Sometimes that has been money foolishly spent when problems have developed prematurely. Sometimes I buy the cheaper thing with full knowledge that it is not going to be as durable as a more expensive item, but that's okay as it is being bought for a one time specific task. Sometimes the cheaper thing is wonderful and is at least as good as the more expensive brand name item. Costco's Kirkland brand AA alkaline batteries come to mind there. Anyhow, I just would like to be quoted correctly.
Quote from: MountainDon on August 16, 2010, 03:24:27 PMNot to initiate a flame war, but my understanding of the UL system is as follows.A manufacturer submits a product for testing. They pay for the testing process up front. If the item passes the UL scrutiny the manufacturer gets permission to have labels printed and applied to the products they then can sell as an approved item. The manufacturer supplies the products to be tested and pays for the testing and approval process. The manufacturer then buys labels from authorized sources. Yes, the labels have to be approved too. The manufacturer also pays subsequent fees for follow up testing on items selected at random as they are produced. Not every item labeled is actually tested.In other words, the manufacturer does not pay a fee based on the number of labels applied. If they get something approved and then don't sell any they have the up front costs paid. With the above being my understanding of the UL process I do not think it likely that the exact same products are sold as approved and unapproved and with such widely divergent prices. Maybe I'm misinformed. If so point me in the right direction.
