I am interested in buying some of your new black 250 watt panels. I understand that the aluminum frame is anodized black but are you using black solar cells? I have read recently that there is research into a new black solar cell that is much more efficient. Are the cells you use in these black panels different from the traditional blue cells we are all familar with. The second question involves the temperature difference as black would absorb more heat than blue and as I understand efficiency drops as temperature rises. And last, do you see the single panel (not kit) prices continue to drop dramatically or will it level off around $.75 /watt?
Thanks

The solar cells we use on our Monocrystalline Panels seem to be black, but they are just a very dark blue so they almost appear black in the sun. We do not use the new black solar cell you are talking about.
As far as your question on temperature, it is true that the efficiency does drop with a temperature increase. Monocrystalline Panels are generally more efficient, but under high temperatures the Monocrystalline Panels eventually become slightly less efficient than the Polycrystalline Panels.
We don't see the price decreasing that much more and believe it will level off at about $.75/watt. It would take another innovation in Solar Panels in order for the price to decrease dramatically.
