Eric. Re...Are we going to spend more fixing our roofs, how do they mount to the roof without causing leaks? What about high wind storm conditions? Do they create air foils of themselves?
Very well put. And that is what I tried to tell him. Washing of the panels is just one of many problems you have when you put them on the roof. However, if you build the house from scratch, not retrofit it, many of the problems you present can be taken care of, with proper engineering, even cleaning.
What most people here don't realize, is that I did business for 2 contractors, who built energy efficient homes, in the 80s. Both of them have quit building them; because the hype, difficulties and costs, didn't live up to the benefits, even on homes, built with energy efficiency from the scratch. Retrofits, by the mid to late 80's had also disappeared. And I haven't seen John, or anyone else address sufficiently the problems. Without that, solar, on homes will be a pipe dream. First solar needs to prove itself, under ideal conditions, (in the desert, under maximum sun, clean conditions), before solar can begin to think about anywhere else. |
